Deep down, way deep down, there's something stirring - something very, very valuable. It's a race to the bottom - to the bottom of the oceans. It is Deep Sea Mining. As deep as 5000 metres, maybe more, lie a host of materials critical for modern society, from smartphones to electric cars to green energy. But how can be it be mined without ruining another beautiful, so-far untouched - yet valuable part of our planet? Joining us on skype from Kingston, Jamaica Michael Lodge, Secretary-General at the International Seabed Authority; from Washington DC, Conn Nugent, Project Director of Seabed Mining Project at the Pew Charitable Trusts; Regan Drennan, Research Assistant at UK Seabed Resource who studies the biodiversity of the ocean floor; Charlotte Middlehurst, a Contributing Editor at China Dialogue, focusing on China's growing interest in deep sea mining. Roundtable is a discussion programme with an edge.

Everyone is aware of off-shore oil rigs; these platforms drill down underwater for valuable resources just off the coast of many nations. But, deep in the ocean beyond national aquatic boundaries lies an abundance of natural resources such as gold, copper, manganese and zinc. State-sponsored companies are surveying and staking claim to these resources, but so far, no one has been granted approval to begin extracting them. The International Seabed Authority (ISA) — the governing body that oversees all activities in international waters (known as the Area) — is currently developing regulations for the extraction of marine minerals. Rules and procedures that govern liability for damage arising from mining activities will be crucial aspect of this regulatory framework. Who is responsible when an environmental disaster occurs as a result of mining activities? To assist in clarifying these legal issues of responsibility and liability, the Centre for International Governance Innovation (CIGI), the Commonwealth Secretariat and the Secretariat of the International Seabed Authority established the Liability Issues for Deep Seabed Mining project. Under the direction of Neil Craik (CIGI), Hannah Lily (Commonwealth Secretariat) and Alfonso Ascencio-Herrera (ISA Secretariat), this project seeks to provide a foundational understanding of key questions surrounding the further development of liability rules.

The contribution of the United Nations Convention on the Law of the Sea to good governance of the oceans and seas - The International Seabed Authority and the public, private and Humanity Interests The conservation and management of the oceans and the seas require an adequate international legal framework. This framework began to be formulated within the III United Nations Conference on the Law of the Sea during the seventies of the last century. It manifested itself in a large international agreement, which has been opened for signature on the 10th of December 1982 -- the United Nations Convention on the Law of the Sea -- of which, nowadays, more than 160 States and the European Union are parts of. In fact, the 10th of December 2012 marks the 30th anniversary of its signature. On that occasion, the IV Colloque ordinaire de l'Association Internationale du Droit de la Mer on "The Contribution of the United Nations Convention on the Law of the Sea to Good Governance of the Oceans and Seas" will be held at the Faculty of Law, University of A Coruña. The thirty years since the signature of this Convention allow us to examine its impact on the evolution of the maritime legal system, its adaptability to the transformations of maritime relations, and, to discuss the appropriateness or not for developing or reviewing this Convention or some of its rules and institutions.

=== Abstract === Deep-sea mining is the process of retrieving mineral deposits from the deep seabed, the area of the seabed below 200m. Whilst there has been interest in the deep seabed since the 1970s, there has been growing interest in recent years due to the depleting deposits from terrestrial sources of metals such as manganese, coupled with the increasing demand for the same metals in green technologies such as wind turbines. Each resource type will have specific challenges, solutions, technologies and mining techniques. In essence, all will require seafloor vehicles to crush and collect the material which will then be fed to the support vessel. However, as the deep sea remains understudied and poorly understood, there are many gaps in our understanding of its biodiversity and ecosystems. This makes it difficult to thoroughly assess the potential impacts of deep-sea mining and to put in place adequate safeguards to protect the marine environment. As there are likely to be impacts beyond our current knowledge, the International Seabed Authority (ISA) is operating a dual mandate of promoting the development of deep-sea minerals whilst ensuring that this development is not harmful to the environment. As such, they are currently going through the process of consultation with the international community (government representatives, scientific community, private contractors etc.) to ensure that the marine life is adequately protected. This presentation will discuss why deep seabed mining is gaining traction and review the governance to date looking at what is already in place and where the gaps are. === Speaker: David Carlin, Ocean Governance SIG - https://www.imarest.org/special-interest-groups/ocean-governance === David is the Science Director at CEFAS, and has worked primarily on science, evidence and advice in support of the regulation of activities in the marine environment.

Video presentations from the Morss Colloquium. http://www.whoi.edu/page.do?pid=28896 Deep-Sea Mining of Seafloor Massive Sulfides: A Reality for Science and Society in the 21st Century Deep-sea hydrothermal vent systems are attracting considerable interest from commercial mining companies. Vent systems precipitate seafloor massive sulfide (SMS) deposits that are rich in copper, gold, silver, and zinc. Although commercial firms are targeting inactive SMS deposits, these deposits are so little studied that it is unknown whether they harbor unique species or ecosystems. The new frontier of deep-sea exploration and mining raises a number of questions about the sustainable use of these resources and potential environmental impacts. This Workshop and Colloquium was held on April 1 - 2, 2009, and brought together scientists, specialists in marine conservation, mineral economics, international law, the International Seabed Authority, national interests in SMS, and representatives of industry and NGOs to inform each other, and the public, about this important topic. The issue of deep-sea mining of SMS is of global importance, connected to the global economy, society, and the conservation of unique marine life.

Surging demand for the metals used in electric car batteries is setting off a race to mine the deep seas. As the FT’s Henry Sanderson explains, the sea floor could contain more nickel, cobalt and rare earth metals than all land-based reserves combined. Miners say it may diversify supply, but environmentalists fear mining will do irreparable damage.

The focus will be on technologies for deep-sea mining, underwater vehicles, underwater robotics and ocean climate change advisory services, among other aspects. Ministry of Earth Sciences, Government of India is all set to launch ‘Deep Ocean Mission’ by January 2018. This will improve India’s position in ocean research field. Shri M Rajeevan, Secretary, Ministry of Earth Sciences announced. Secretary was speaking through video conference in the workshop arranged by National Institute of Oceanography, Dona Paula. Shri M S Nagar, Member Standing Committee, Ministry of Earth Science, Dr VSN Murthy, Director, National Institute of Oceanography were also present at the inauguration of the workshop on ‘Three decades of India acquiring Pioneer Investor Status- Achievements and way forward’. India achieved a lot in the field of ocean research; still it is long way to go, said Secretary M Rajeevan on this occasion. The program on Poly metallic nodules was initiated at CSIR-NIO with the collection of the first nodule sample from Arabian Sea on board the first Research Vessel Gaveshani on 26 January 1981. India was the first country in the world to have been given the Pioneer Area for exploration of deep-sea mineral viz. Polymetallic nodules in the Central Indian Ocean Basin in 1987. This was based on the extensive surveys carried out by the scientists of CSIR-NIO, on several research ships leading to the allocation of an area of 150,000 sq km to the country with exclusive rights under the UN Law of the sea. Subsequently, Environment Impact Assessment studies for nodule mining by CSIR-NIO, development of metal extraction process by CSIR-National Metallurgical Laboratory, Jamshedpur and CSIR- Institute for Minerals and Metals Technology, Bhubaneswar and development of mining technology by National Institute of Ocean Technology, Chennai, have been taken up under the national program on Polymetallic nodules funded by Ministry of Earth Sciences. Based on the resource evaluation, India has now retained an area of 75,000 sq km with an estimated resource of about 100 million tons of strategic metals such Copper,Nickel, Cobalt besides Manganese and Iron. A First Generation Mine-site (FGM) with an area of 18,000 sq km has been identified. Latest technologies for extraction of metals from the minerals have also been developed under the programme. Detailed environmental data has been collected for compliance with International Seabed Authorities requirements. Besides identifying the mineral resource and developing technologies for mining and extraction, the programme has also resulted in high impact research as well as manpower development.

“Oceanography: Mining Mineral In The Ocean” is an issue of the Science Screen Report, presented by United Technologies Sikorsky Aircraft, that discusses the potential and problems of have deep-sea mining for minerals. The issue opens with shots of the sea, which is a “reserve of global resources,” including metals from deep-sea nodules (polymetallic nodules). These nodules cover vast areas of the sea bottom, and their potential is the reason for a major deep-ocean project being carried out. Deep Sea Nodules can be the size of potatoes, and their porous structure accumulates layers of various metals. They are very slow growing, but sizeable nodules cover areas of the sea floor, providing a significant reserve of metals. As part of the project to determine the mining feasibility of nodules, the first self-propelled robot miner (01:38) is developed and tested. Scientists examine nodules in a lab (02:52), but to answer a number of questions surrounding them, the National Science Foundation uses Research Vessel Melvillle (03:12) to carry out underwater tests. Members of the crew lower sound beacons to create a grid (03:35). Then a robot mapping vehicle is lowered into the water to gather data within the grid. In the control room (04:10), the team monitors the robot’s data. The next step is the collection of sea floor samples (05:08); a box corer is lowered into the water to gather sample nodules, transporting nodules and their environment to the surface. Scientists examine the contents, conduct tests, and record data. The results indicate nodules may grow similar to coral. Next, piston corers (06:52) are used to take out samples of core sections of the floor to add to the mission’s overall understanding. After two weeks, the samples and data are collected, stored, and made accessible to over 50 research centers throughout the world. The next phase involves exploration ship Governor Ray (08:06), which monitors a sea mining research site, and Glomar Explorer (08:22), a surface platform ship (originally built as a deep-sea recovery platform for the CIA as part of Project Azorian also known as Project Jennifer) with an internal dry dock that holds the advanced robot miner. The crew preps for launch day by filling the dry dock, opening the doors (11:00), and moving the robot miner into the water. The robot miner hangs under the ship as pipe attachments are installed, connecting the miner and processor to transport nodule slurry. The robot miner is positioned and the processor is attached to it, enabling the mining operation to begin (12:18). Sonar and TV images show how easily the miner collects nodules as is moves across sea floor capturing images and harvesting nodules, which are crushed into a slurry and piped up to the ship. A commercial miner would be 10 times the size of the robot miner, but the smaller robot miner is the first step in the eventual commercial mining of the sea’s unique nodules. Background on this ... historic film is that it shows techniques used to conduct deep ocean mining of the sea floor, which were pioneered in the 1960s. The potential for this type of mining (particularly of manganese nodules) was never fully realized. Ironically, the program did end up providing the cover for the USNS Hughes Glomar Explorer (T-AG-193), a deep-sea drillship platform built for the United States Central Intelligence Agency Special Activities Division secret operation Project Azorian to recover the sunken Soviet submarine K-129, lost in April 1968. Hughes Glomar Explorer (HGE), as the ship was called at the time, was built between 1973 and 1974, by Sun Shipbuilding and Drydock Co. for more than US$350 million at the direction of Howard Hughes for use by his company, Global Marine Development Inc. This is equivalent to $1.67 billion in present-day terms. She set sail on 20 June 1974. Hughes told the media that the ship's purpose was to extract manganese nodules from the ocean floor. This marine geology cover story became surprisingly influential, spurring many others to examine the idea. But in sworn testimony in United States district court proceedings and in appearances before government agencies, Global Marine executives and others associated with Hughes Glomar Explorer project unanimously maintained that the ship could not be used in any economically viable ocean mineral operation.

Get the facts about the high seas—the two-thirds of our world’s oceans that are not under any country's jurisdiction. This quick whiteboard tutorial explains why these international waters are so important and how the United Nations can help protect high seas marine life and ocean resources. *TRANSCRIPT* Beyond the waters under the jurisdiction of coastal countries lies a vast region that few will ever see first-hand, but on which everyone on Earth depends. It’s known as the high seas and covers nearly half of the planet. These waters and the deep seabed that lie beneath them, were once thought to be empty— but they are actually full of life. Sea turtles, whales, sharks, and migratory fish spend much of their lives in these waters. They are also home to hydrothermal vents, unique seamounts and geomorphic structures, deep sea corals, uniquely adapted fish species, and tiny organisms—many of which have yet to be discovered. The high seas are vital to the global ocean ecosystem; providing much needed protein to a growing population. Nearly 10 million tons of fish are caught each year on the high seas—generating more than $16 billion once landed. And the fishing and shipping industries rely on the high seas to provide economic security and jobs. But the high seas are under threat. As shipping and fishing industries continue to grow and new activities such as rocket launches, power generation, aquaculture, and seabed mining emerge, the demands on the high seas are an increasing burden. While shipping, mining, and fishing are regulated by international organizations, there is still no management for many new activities, or coordinated governance of existing high seas industries. In June 2015, the United Nations agreed to begin negotiations over a new international treaty to protect high seas biodiversity. This treaty is the first of its kind and for how our valuable ocean resources are managed. The new treaty could allow countries to protect important and vulnerable parts of the high seas by creating marine protected areas and reserves. And it could require environmental impact assessments for commercial operations to determine when, where, and whether various activities should be allowed. Achieving a strong treaty will need the efforts of government leaders and officials from around the world—and broad support from those who make their living from the ocean, feed their families from it, or just love it. Now is the time to secure a robust new international agreement that ensures the health of the high seas for generations to come. For more information, visit www.pewtrusts.org/highseas.

"Common heritage of mankind" is a principle of international law which holds that defined territorial areas and elements of humanity's common heritage should be held in trust for future generations and be protected from exploitation by individual nation states or corporations. Immanuel Kant in his essay "Toward Perpetual Peace" claimed that the expansion of hospitality with regard to "use of the right to the earth's surface which belongs to the human race in common" would "finally bring the human race ever closer to a cosmopolitan constitution". The concept of "Common Heritage of Mankind", however, was first mentioned in the preamble to the 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict and specifically enunciated as an obligation under international law in the Outer Space Treaty of 1967. Some initial provisions of that treaty state: The concept of "common heritage of mankind" also appears in the Moon Treaty. Article 11 states that “ he Moon and its natural resources are the common heritage of mankind”. The Antarctic Treaty, though it does not mention the principle expressly, states in its preamble that its primary purpose is to ensure “in the interest of all mankind that Antarctica shall continue forever to be used exclusively for peaceful purposes and shall not become the scene or object of international discord”. The concept of 'Mankind' is also mentioned in other outer space treaties. 'Mankind' as a subject in international law also appears in the Preamble of the United Nations Charter, the Preamble of the North Atlantic Treaty and the Treaty on the Non-Proliferation of Nuclear Weapons .

Composed of nine volcanic islands that once thrived on the whaling industry, the Azores have since become a hot spot for research in marine biology due to its diverse ecosystems, as it is located above an active triple junction between the Eurasian, African, and North-American tectonic plates. In 2008, one year before Portugal submitted its proposal to extend its continental shelf to the United Nations, the Canadian mining company Nautilus Minerals Inc. presented a proposal for mineral prospection and exploration in six areas off the coast of the Azores. Despite the fact that deep sea mining continues to be under debate between different governmental bodies, no effort was done to inform the wider public or local citizens about such plans. For this episode we interviewed different specialists in marine biology based in the islands, among them José Nuno Gomes-Pereira, Teresa Cerqueira, Telmo Morato, and Gisela Dionísio, as well as member of the European Parliament Ricardo Serrão Santos, on the potential impacts of deep sea mining on local ecosystems and on the archipelago’s economical reality. What is Deep Sea Mining? is developed in collaboration with Margarida Mendes, curator and activist from Lisbon, Portugal, and founding member of Oceano Livre environmental movement against deep sea mining.

Recent years have seen increased survey and sampling expeditions to the Clarion-Clipperton Zone (CCZ), central Pacific Ocean abyss, driven by commercial interests from contractors in the potential extraction of polymetallic nodules in the region. Part of the International Seabed Authority (ISA) regulatory requirements are that these contractors undertake environmental research expeditions to their CCZ exploration claims following guidelines approved by the ISA Legal and Technical Commission (ISA, 2010). Section 9 (e) of these guidelines instructs contractors to “…collect data on the sea floor communities specifically relating to megafauna, macrofauna, meiofauna, microfauna, nodule fauna and demersal scavengers”. There are a number of methodological challenges to this, including the water depth (4000–5000 m), extremely warm surface waters (~28 °C) compared to bottom water (~1.5 °C) and great distances to ports requiring a large and long seagoing expedition with only a limited number of scientists. Both scientists and regulators have recently realized that a major gap in our knowledge of the region is the fundamental taxonomy of the animals that live there; this is essential to inform our knowledge of the biogeography, natural history and ultimately our stewardship of the region. Recognising this, the ISA is currently sponsoring a series of taxonomic workshops on the CCZ fauna and to assist in this process we present here a series of methodological pipelines for DNA taxonomy (incorporating both molecular and morphological data) of the macrofauna and megafauna from the CCZ benthic habitat in the recent ABYSSLINE cruise program to the UK-1 exploration claim. A major problem on recent CCZ cruises has been the collection of high-quality samples suitable for both morphology and DNA taxonomy, coupled with a workflow that ensures these data are made available. The DNA sequencing techniques themselves are relatively standard, once good samples have been obtained. The key to quality taxonomic work on macrofaunal animals from the tropical abyss is careful extraction of the animals (in cold, filtered seawater), microscopic observation and preservation of live specimens, from a variety of sampling devices by experienced zoologists at sea. Essential to the long-term iterative building of taxonomic knowledge from the CCZ is an “end-to-end” methodology to the taxonomic science that takes into account careful sampling design, at-sea taxonomic identification and fixation, post-cruise laboratory work with both DNA and morphology and finally a careful sample and data management pipeline that results in specimens and data in accessible open museum collections and online repositories. Box core procedures and recommendations are based on the protocols used and developed by the Craig R. Smith Lab, University of Hawaii.

The 21 mollusc species newly described thanks to the latest DNAtaxonomy methodology. Credit Adrian Glover, Thomas Dahlgren, Helena Wiklund Scientists working in the new frontier for deepsea mining have revealed a remarkable 2000% increase in our knowledge of the biodiversity of seafloor molluscs. Twentyone species, where only one was previously known, are reported as a result of the research which applied the latest DNAtaxonomy methodology to mollusc specimens collected from the central Pacific Clarion Clipperton Zone CCZ in 2013. They are all described in the open access journal ZooKeys. Among the discoveries is a monoplacophoran mollusc species regarded as a living fossil, since it is one the ancestors of all molluscs. This is the first DNA to be collected from this species and the first record of it from the CCZ mining exploration zone a vast 5millionkm² region of the central Pacific that is regulated for seabed mining by the International Seabed Authority. Despite over 100 survey expeditions to the region over 40 years of mineral prospecting, there has been almost no taxonomy done on the molluscs from this area, says lead author Dr Helena Wiklund of the The Natural History Museum in London NHM. Dr Wiklund undertook a comprehensive DNAbased study of the molluscs to confirm species identities and make data available for future taxonomic study. This was coupled with the expertise of the NHMs Dr John Taylor, who led the morphological work. The video will load shortly. This video shows sampling methodologies including box core sampling. Credit Adrian Glover, Thomas Dahlgren, Helena Wiklund The molluscs were found in samples taken on and in the mud surrounding the potatosized polymetallic nodules that are present in high abundance across the CCZ. These nodules are the target for potential deepsea mining being rich in cobalt, copper, nickel, manganese and other valuable minerals. The data are vital for the future environmental regulation of deepsea mining, but have als... Thank for watching, Please Like Share And SUBSCRIBE!!!

Papua New Guinea’s National Forest Authority has big plans to develop forest plantation. It seems an ambitious plan – 800, 000 hectares of commercial tree species by 2050. Is this achievable? And what obstacles are there, that may hinder fulfilling this target? Also on this episode, PNG has been a leader in the extractive industry, and this has been evident in recent years. The world’s first deep sea mining project, Solwara 1, being developed by Nautilus Minerals off the coast of East New Britain and New Ireland Provinces, has been in the spotlight right from the very start, and now, the Pacific Council of Churches has weighed in on that issue. - visit us at http://www.emtv.com.pg/ for the latest news...

Talk Overview 90% of geophysicists in the world explore for oil and gas. Another 5% explore for mineral resources. And another 4.9% teach and regulate the previous 95%. In today's world, fluctuating commodity prices and mountainous stockpiles of recycled metals tell us that we have too much oil, uranium, coal, and iron ore. Today and in the foreseeable future, what the world is drastically scarce of is clean water, clean soil, and a common cultural legacy. Those remaining less than 0.1% of geophysicists not accounted for, above, are dedicated to developing techniques to explore for potable water, mapping soil salinization, demining previously productive agricultural land, and delineating subsurface remains of culturally rich sites threatened by development. With examples from Africa, Asia, Australia, and the Middle East, we can see how these non-destructive subsurface investigation techniques can radically improve life not only on a local and regional scale, but even on a continent wide scale. And where we are not using these approaches, we can envision how the development of access to clean water, clean soil, and mankind's cultural legacies can be greatly improved. Speaker Profile Paul Bauman is the Technical Director of the Geophysics group at WorleyParsons, in Calgary, where he has been working since 1990. He is one of the world experts on near surface applications of borehole and surface geophysical methods as applied to investigations in water resources, archaeology, soil science, geotechnical engineering, subsurface contamination, and geohazard identification. Paul has a B.Sc.E. in Geological Engineering from Princeton University, a Minor in Near Eastern Studies from Princeton, and an M.Sc. in Earth Sciences from the University of Waterloo. Paul has published widely in peer reviewed journals, scientific volumes, and conference proceedings. He has presented geophysical papers at over 100 conferences in an extraordinarily wide range of disciplines including geophysics, soil science, hydrogeology, disaster relief, archaeology, water resource development, contaminant hydrogeology, mining, mine waste management, heavy oil, shallow gas, salt water intrusion, salt water intrusion, etc. He has been an invited speaker at many educational, professional, and government institutions including Princeton University, Boston University, California State, the University of Pennsylvania, the National Water Authority in Yemen, the Israel Museum in Jerusalem, the Royal BC Museum, and the Prince of Wales Northern Heritage Centre in Yellowknife. Aspects of his archaeogeophysical work have been the subject of a NOVA documentary (Ancient Refuge in the Holy Land), numerous radio and television interviews, a National Geographic movie entitled "Finding Atlantis," and numerous newspaper and magazine articles including in Time, National Geographic, and the Reader's Digest. Paul's work in the Cave of Letters and other sites is featured in the recently published popular books Secrets of the Cave of Letters: Rediscovering a Dead Sea Mystery; Digging Through the Bible: Modern Archaeology and the Ancient Bible; and Digging through History: Archaeology and Religion from Atlantis to the Holocaust. Ongoing archaeogeophysical projects include the subsurface imaging of a Roman bath house from the time of Jesus, located in Nazareth; the geophysical mapping of the ancient Phoenician harbour of Tel Akko, perhaps the first constructed harbour in the world; and the geophysical mapping of the destroyed and buried remains of a World War II Nazi extermination camp at Sobibor, Poland. A few water resource projects of note include the introduction of an entirely new approach to water exploration in Africa, which raised success rates in drilling from less than 20% to over 90% in Malawi; innovative and successful geophysical water exploration programs in Yemen which tapped previously unused aquifers in areas that had gone years without significant rainfall; and the secondment to UNICEF to assess the impact of the 2004 Boxing Day Tsunami to the water resources of Aceh Province in Indonesia, and to begin the redevelopment and rehabilitation of water supplies to the region -- besides being an experienced geophysicist and hydrogeologist, Paul speaks fluent Indonesian and Malay.

Earth's carbon cycle operates in different ways over short and long term timescales. Over timescales of years to decades the dominant global processes governing the amount of CO2 in the atmosphere are world photosynthesis by plants and algae, and respiration by consumer-organisms of organic compounds back to CO2 in air. Global air CO2 concentrations are broadly increasing as a result of the burning of fossil fuels by human civilization, but superimposed on that modern trend is a very old trend of yearly ups and downs in the concentration of CO2 in air. Our planet's forests are mostly in the northern hemisphere, and their springtime & summer intake of CO2 drops air concentrations by up to 5 or 6 ppm, and CO2 release during autumn & winter by decomposition of dead plant biomass (e.g. leaves) raises CO2 back up by about 5 or 6 ppm. It happens every year, and has for a geologically long time. Global reservoir box-models are useful in figuring out how cyclic processes like the carbon cycle operate. The atmosphere contains about 760 Gigatons (Gt) of carbon (C) and every year photosynthesis draws about 60 Gt of C out of the air. About half that amount of plant biomass is directly consumed by animals and microbes, which directly respire that carbon back to air as CO2. The other half of annual world plant primary-productivity, approximately, is deposited in soil and decomposed back to air as CO2. Soils and young marine sediments are a large reservoir of C, about 1,600 Gt, and organic carbon that enters this reservoir and is not immediately decomposed back to CO2 may spend centuries or longer in that form. In the oceans the situation is different because there are no oceanic trees, there are no long-living giant organisms that sequester lots of C. Most primary productivity in the oceans is accomplished by algae and other forms of phytoplankton, which are single-celled or multicellular microscopic life forms. Primary productivity in the oceans is focused at the top, in the photic zone where light can penetrate, roughly 100 m depth. Life grows there but as individual planktonic life forms die they fall down slowly through the deeper, darker ocean depths. As they fall they are almost completely decomposed by bacteria or eaten by zooplankton - tiny floating animals. Only about 1% of biomass that sifts down through the ocean water as "marine snow", dead plankton, finds its way into longer-term storage in sediment on the seafloor. Most falling biomass is converted back to CO2 dissolved in ocean water. The overall process of falling dead plankton decomposing on the way down is called the Marine Biological Pump, which has the overall effect of exporting C and nutrients from the shallow ocean and delivering them by gravity & decomposition to the deep ocean. The Marine Biological Pump depletes surface ocean waters of C & nutrients, and enriches the deep ocean in dissolved CO2 and nutrients derived from planktonic carcasses.

One of the most crucial national projects now ongoing in Ireland represents a significant potential which must now be tapped and augmented as part of the strategic and scientific global re-alignment now in process. The work currently underway and the plans being developed, as outlined on the Marine Institute website, give an indication of this potential. Besides the tremendous, immediate economic benefits of, for example, the development of ship building industries and an engineering capability for the new field of deep-ocean mining, the key prize for a new Irish Republic is the prospect of a leadership role at the forefront of scientific exploration which may have untold significance for mankind in the future. In July of this year, the Celtic Explorer sailed for the hydrothermal vents around the mid-Atlantic Ridge on a groundbreaking mission to research and catalogue the "alien" deep-sea chemosynthetic life forms which live without sunlight off of the heat-energy and chemicals which erupt from these ocean-floor vents. Patrick Collins, from the National University of Ireland Galway's Ryan Institute, was on board to catalogue and characterize the various species found at the vents. Collins leads Ireland's marine biological team currently investigating this unique and extraordinary ecosystem. Collins said that this research could give us valuable insight about how life might have evolved on other planets, as well as being a rich source of new understanding of biochemical processes with valuable medical and industrial applications. According to Patrick, "We hope to find a whole community of previously unknown species, increasing our understanding of deep sea biogeography. There is potential here to put Ireland on the global map as a serious player in deep sea science. This is all the more timely with the exploitation of deep sea and hydrothermal vents for precious metals and rare earth minerals now a reality." The development of the Shannon Estuary should be approached with the same bold view and nation building passion as was the building of the Shannon Scheme. This project, which aimed to electrify Ireland, inspired the then Governor of New York State, Franklin Delano Roosevelt, to enquire into the building of the scheme and to undertake the similar implementation of the Tennessee Valley Authority when he was elected President of the United States of America. But although plans were announced by the state-owned Shannon Foynes Port Company in 2004, for a 350 million euro investment to transform the River Shannon Estuary into one of Europe's largest cargo hubs, the plans have barely moved beyond the public discussion stage. Although the investment is a welcome move, it should be seen as only the first step towards the development of an international deep water shipping resource which will rival Shanghai and Rotterdam as the biggest port complex in the world. This new Shannon Super-Port, connected by high speed maglev rail to the Tuskar Tunnel between Wexford and Pembrokeshire, could facilitate the efficient delivery of freight right into the heart of Europe. The plan mandated by the provisions of the bailout package, to rationalize and sell off the Shannon Foynes Port Company, will no doubt be rejected by the Irish people, as it becomes clear what a crucial asset the Shannon Estuary is. http://www.larouchepac.com/node/20614 Full article: http://laroucheirishbrigade.wordpress.com/

Les explorations scientifiques menées dans les grands fonds depuis 40 ans ont identifié plusieurs processus géologiques et géochimiques conduisant à la concentration de métaux dans les nodules, les sulfures hydrothermaux et les encroutements de manganèse. Ces minéralisations sont générées par des processus actifs spécifiquement sous-marins. L’identification de leur potentiel économique se traduit, depuis quelques années, par des demandes de permis d’exploration. Dans les eaux internationales, l’International Seabed Authority (ISA) a accordé 19 nouveaux permis depuis 2010. Le développement de ces activités sous-marines nécessite de préciser les impacts potentiels de l'exploration et de l'exploitation sur les écosystèmes et de définir les services écosystémique qu'ils assurent. L’efficacité des actions d’exploration, de connaissance scientifique et de gestion environnementale est fortement liée à l’évolution des technologies de travail dans les grands fonds. source : http://www.college-de-france.fr/site/georges-calas/symposium-2015-06-04-15h15.htm

Japan launches survey of Pacific for rare earth metals: Japan is ready to start a survey of the Pacific Ocean, hoping to find large deposits of rare earth minerals, below the ocean floor. Used in everything from electronic devices to electric cars, securing a source of the metals would help Japan rely less on supplies from China. As the BBC's Rupert Wingfield-Hayes reports from Tokyo, the Japanese are motivated by political as well as economic concerns.
