  • Shedding light on the cinderellas of the deep sea

    Ocean sponges from shallower waters have already been shown to be valuable sources for new medicinal drugs to treat cancers and for antibiotics, and it is expected that deepwater sponges will be equally valuable, if not more so. A groundbreaking new report, Deep-sea Sponge Grounds: Reservoirs of Biodiversity, which consolidates knowledge on the biology and ecology of deep-water sponge grounds, ...

  • Review claims `poor science` in deep-sea mining report

    A debate has erupted over the scientific validity of the environmental impact statement (EIS) of the world's first deep-sea mine, located off the coast of Papua New Guinea (PNG). The furore may push the PNG government to convene a further roundtable meeting for experts, before the mine becomes operational next year. ...

  • India backs exploration of rare earths in deep sea

    With China controlling most of valuable rare-earth mineral supplies, India makes a strategic move to back exploration off its own coast, writes Paula Park. India has joined the race to explore and develop deep-sea mining for rare earth elements — further complicating the geopolitics surrounding untapped sources of valuable minerals beneath the oceans. The country is building ...

  • Scientific sub makes deep-sea discoveries

    The collaborative voyage of US and Australian researchers was led by chief scientists Dr Jess Adkins from the California Institute of Technology and Dr Ron Thresher from CSIRO’s Climate Adaptation and Wealth from Oceans Flagships. “We set out to search for life deeper than any previous voyage in Australian waters,” Dr Thresher says. “We also gathered data to assess the threat posed by ocean ...

  • New directions for protecting deep-sea biodiversity

    The deep sea is vulnerable to human impacts and environmental changes. A recent report provides an insight into deep-sea ecosystems and makes recommendations for future research and policies to protect deep-sea species and habitats. Two thirds of the Earth's surface is covered by ocean waters more than 200 metres deep, referred to collectively as the deep sea. Yet there remains a lack of ...

  • Southern Ocean winds open window to the deep sea

    The researchers’ findings – published on-line today in Nature Geoscience – provide new insights into natural processes which have a major influence on the rate of climate change. The surface-mixed layer is a crucial pathway between the atmosphere and the deeper layers of the ocean. Changes in the depth of the mixed layer can affect air-sea exchange, carbon and heat storage in the ocean, and the ...

  • Pacific islands seek protection from deep-sea mining

    Surging interest in deep-sea metal mining in the Pacific Ocean has prompted island nations to work together to develop the scientific capacity needed to protect their environment. The move follows the discovery of large deposits of rare-earth metals such as scandium on the seabed near Hawaii, Tahiti ...

  • Pew Urges Reforms to EU Deep-Sea Fishing Regulations

    The Pew Environment Group today encouraged the European Commission to implement significant reforms to EU deep-sea fishing regulations. The Commission is preparing to release its deep-sea access regime proposal before the end of the first quarter of 2012. In a new policy analysis, " ...

  • Expedition to test new technologies for deep sea deposit exploration

    A research cruise this summer, led by the National Oceanography Centre (NOC), will address the massive technical challenges in exploring for sea-floor mineral deposits. This expedition will take place on board the RRS James Cook, marking a decade of service that has seen this ship travel 218,972 miles in pursuit of science – the equivalent of circumnavigating the globe ten times. Seafloor ...

  • Conservation Organizations: NAFO Falls Short on Deep-Sea Protections

    The 33rd annual meeting of the Northwest Atlantic Fisheries Organization (NAFO) ended today with countries failing to agree on significant, additional measures to safeguard vulnerable deep-sea marine ecosystems. While NAFO has made progress since 2006 in closing certain seamounts and areas of corals and sponges to fishing—including deciding at this year's ...

  • Deep-sea mining looms on horizon as UN body issues contracts

    The deep oceans span more than half the globe and their frigid depths have long been known to contain vast, untapped deposits of prized minerals. These treasures of the abyss, however, have always been out of reach to miners. But now, the era of deep seabed mining appears to be dawning fueled by technological advances in robotics and dwindling land-based deposits. Rising demand for copper, ...

  • Study Shows Widespread Climate Changes Underway in B.C`s Oceans Affecting Fisheries, Deep Sea-Diversity and Coastal Habitats

    A newly-released report by WWF and the Canadian Parks and Wilderness Society (CPAWS) reveals that the effects of climate change are reducing fish habitat on B.C.'s coast, threatening the province's lucrative groundfish and shellfish fisheries. The study is the first regional synthesis of its kind to document observed and expected impacts of a changing global climate on B.C's marine ecosystems and ...

  • New research questions just how cold the Antarctic deep seas can get

    Scientific knowledge of the deep seas surrounding the Antarctica is minimal at best, which is why new research missions are valuable to increasing our knowledge of the area. One such recent mission has revealed that the Antarctic deep sea is getting colder, and that this drop in temperature may have important implications for the circulation of the oceanic water masses. This is the first result ...

  • Rising Sea Levels – The New Reality

    Water may be flowing from the Greenland icecap and into the sea more quickly than anybody expected. It doesn’t mean that global warming has got conspicuously worse: rather, researchers have had to revise their understanding of the intricate physiology of the northern hemisphere’s biggest icecap. Climate calculations Since ...

  • Encroaching sea already a threat in Caribbean

    The old coastal road in this fishing village at the eastern edge of Grenada sits under a couple of feet of murky saltwater, which regularly surges past a hastily-erected breakwater of truck tires and bundles of driftwood intended to hold back the Atlantic Ocean. For Desmond Augustin and other fishermen living along the shorelines of the southern Caribbean island, there's nothing theoretical about ...

  • Deep concern over invisible threat to Antarctic glaciers

    The Antarctic ice shelf is under threat from a silent, invisible agency – and the rate of melting of glaciers has trebled in the last two decades. The ocean waters of the deep circumpolar current that swirl around the continent have been getting measurably warmer and nearer the ocean surface over the last 40 years, and now they could be accelerating glacier flow by melting the ...

  • Deep-ocean sentinels on northern climate watch

    Up to 3,000 metres tall and carrying an array of special marine sensors, the moorings were deployed earlier this month as part of an international collaboration to monitor the Timor Passage and Ombai Strait – two strategic deep ocean channels which act as 'chokepoints' in the global system of ocean currents. Valued at over $1 million, the moorings were deployed as part of Australia's ...

  • We will need to adapt to rising sea levels

    “The good news is that a recent concentration of science resources is improving our insight into ocean and ice dynamics, and scientific measurement of the rate of sea-level rise,” says the book’s lead editor, CSIRO Fellow and oceanographer Dr John Church. “The way the world responds to climate change will become increasingly reliant on a sophisticated integrated ...
