  • Deep sea mining — a dangerous experiment

    Pacific governments should not approve deep-sea mining until more is known about its likely impact, says conservation biologist Mellie Samson Jr. Deep sea mining (DSM) is the new frontier in extractive mining. For the companies involved, as well as the governments that own the mining rights, it offers substantial profits. However DSM is still experimental in nature, with ...

  • Deep sea mining: exploration is inevitable

    Despite concern over adverse impacts, deep marine mineral exploration is set to become a global industry, says geologist Chris Yeats. Global demand for metals continues to grow, fuelled largely by increasing populations and the industrialisation and urbanisation of China and India. To meet this demand, the international ...

  • NASA Science Zeros in on Ocean Rise: How Much? How Soon?

    Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future. Members of NASA's new ...

  • Chile establishes the largest marine protected area in the Americas

    Earlier today Chilean president Michelle Bachelet announced the formation of Nazca-Desventuradas Marine Park — the largest marine protected area in the Americas. Located more than 850 kilometers (530 miles) northwest of Santiago in ...

  • Ocean carbon: A dent in the iron hypothesis

    Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the ...

  • Seeding the oceans may not stop climate change

    Geo-engineering against climate change – Seeding the oceans with iron may not address carbon emissions Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large quantities of iron salts in the oceans to ...

  • The number one thing we can do to protect Earth’s oceans

    Marine governance favors consumption and commerce over conservation. Here's what we can do about it. When New England fishers complained of working harder and harder to catch fewer and fewer fish, Spencer Baird assembled a scientific team to investigate. Though a fishery failure would once have seemed inconceivable, Baird wrote in his report, “an alarming decrease of the ...

  • Where Has All the Ice Gone?

    As the earth warms, glaciers and ice sheets are melting and seas are rising. Over the last century, the global average sea level rose by 17 centimeters (7 inches). This century, as waters warm and ice continues to melt, seas are projected to rise nearly 2 meters (6 feet), inundating coastal cities worldwide, such as New York, London, and Cairo. Melting sea ice, ice sheets, and mountain glaciers ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • How a new source of water is helping reduce conflict in the Middle East

    Scientists and others look to desalination as a way to unite longtime enemies in a common cause. Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Enhancement of Terrestrial Carbon Sink Potential: A Possible Contribution to Mitigating Global Warming

    Introduction Climate researcher Klaus Hasselmann, Director of the Max-Planck-Institut (MPI) for Meteorology in Hamburg and a project co-ordinator of EC’s Environment and Climate Programme, was one of the first scientists to warn that recently observed global warming trends have a discernible human related forcing component. Climate model calculations show, that global warming is closely related ...
