By Sarah Kaplan 13 November 2017 (The Washington Post) – In late 1992, 1,700 scientists from around the world issued a dire “warning to humanity.” They said humans had pushed Earth’s ecosystems to their breaking point and were well on the way to ruining the planet. The letter listed environmental impacts like they were biblical […]
By Roger Harrabin 10 November 2017 (BBC News) – Huge quantities of nitrate chemicals from farm fertilisers are polluting the rocks beneath our feet, a study says.Researchers at the British Geological Survey say it could have severe global-scale consequences for rivers, water supplies, human health and the economy.They say the nitrate will be released from […]
6 October 2017 (UvA News) – Gradual environmental changes due to eutrophication and global warming can cause a rapid depletion of oxygen levels in lakes and coastal waters. A new study led by professors Jef Huisman and Gerard Muyzer of the University of Amsterdam (UvA) shows that microorganisms play a key role in these disastrous […]
By Tim Schröder 3 August 2017(Helmholtz-Zentrum Geesthacht) – Nitrogen compounds are an important factor in the production of algal biomass. The team led by biologist Kirstin Dähnke from the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht has been carrying out extensive Elbe nitrogen measurements for this reason.These measurements have shown that regions upstream from […]
By Kathryn Hansen 2 August 2017 (NASA) – Looking over the edge of a boat, it would be easy to mistake the jewel-toned waters for the Caribbean Sea. But you are more likely to find geoducks and barnacles than you are to find grouper and white sandy beaches. In the Pacific Northwest, the water does […]
2 August 2017 (NOAA) – Scientists have determined this year’s Gulf of Mexico “dead zone,” an area of low oxygen that can kill fish and marine life, is 8,776 square miles, an area about the size of New Jersey. It is the largest measured since dead zone mapping began there in 1985.The measured size is […]
By Peter Brannen 11 July 2017 (The Atlantic) – “Who you with?” “I’m a science journalist,” I said, jolted from my reverie on the shoulder of I-68 in Maryland, where a crowd of geologists had gathered on a field trip to poke at some rocks revealed by the highway department’s dynamite. The rocks, slate gray […]
5 June 2017 (United Nations) – Opening a “game-changing” international conference on the health of the world’s oceans and seas, top United Nations officials today urged coordinated global action to protect the planet.Speaking in the UN General Assembly Hall, Secretary-General António Guterres cautioned Governments that unless they overcome short-term territorial and resource interests, the state […]
12 May 2017 (University of Exeter) – Dramatic drops in oceanic oxygen, which cause mass extinctions of sea life, come to a natural end – but it takes about a million years. The depletion of oxygen in the oceans is known as “anoxia”, and scientists from the University of Exeter have been studying how periods […]
ATLANTA, Georgia, 3 May 2017 (Georgia Tech) – A new analysis of decades of data on oceans across the globe has revealed that the amount of dissolved oxygen contained in the water – an important measure of ocean health – has been declining for more than 20 years. Researchers at Georgia Institute of Technology looked […]
