Ocean oxygen levels dropping as world warms – “The decline in ocean oxygen ranks among the most serious effects of human activities on the Earth’s environment”

4 January 2018 (Smithsonian Environmental Research Center) – In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside […]

Global warming has quadrupled ocean dead zones – “The decline in ocean oxygen ranks among the most serious effects of human activities on the Earth’s environment”

4 January 2018 (SERC) – In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as […]

Large river systems are main culprits for plastic pollution in the oceans – “It is still impossible to foresee the ecological consequences of this. One thing is certain, however: this situation cannot continue.”

17 October 2017 (UFZ) – Every year, millions of tonnes of plastic debris ends up in the sea – a global environmental problem with unforeseeable ecological consequences. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was […]

Orcas headed to extinction unless we get them more chinook and quieter waters – “There is an urgency here that is not well-appreciated; they are certainly in jeopardy”

By Lynda V. Mapes 27 October 2017 (The Seattle Times) – Orca whales are on a path to extinction within a century unless they get a big increase of chinook salmon to eat, and significantly quieter seas in which to find their food, a new study has found.The research, published in the journal Scientific Reports, […]
