WASHINGTON D.C., 25 January 2018 (AGU) – Man-made phosphorus pollution is reaching dangerously high levels in freshwater basins around the world, according to new research. A new study published in Water Resources Research, a journal of the American Geophysical Union, estimated the global amount of phosphorus from human activities that entered Earth’s freshwater bodies from […]
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 […]
By James F. McCarty 11 October 2017 (The Plain Dealer) – Approaching the end of another summer marked by a substantial algal bloom in Lake Erie’s western basin, environmental and conservation groups released separate reports Tuesday that came to the same conclusion: Ohio, Michigan and Ontario are falling far short in their efforts to reduce […]
By Alan Burdick 21 September 2017 (The New Yorker) – Every spring, in alpine regions around the world, one of Earth’s tiniest migrations takes place. The migrants are single-celled green algae; they are kin to seaweed, but instead of living in the sea they live in snow. (Snow weed, maybe?) They spend the winter deep […]
By Phuong Le 28 August 2017 SEATTLE (Associated Press) – A marine net pen holding 305,000 farmed Atlantic salmon collapsed recently, releasing thousands of fish into Puget Sound and renewing concerns that a new proposed salmon farm could harm wild salmon stock and cause other environmental damage. The release at Cooke Aquaculture’s facility comes as […]
MEDFORD/SOMERVILLE, 15 August 2017 (Tufts Now) – Harmful algal blooms known to pose risks to human and environmental health in large freshwater reservoirs and lakes are projected to increase because of climate change, according to a team of researchers led by a Tufts University scientist. The team developed a modeling framework that predicts that the […]
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 Jenny Staletovich13 February 2017 SHARK RIVER (Miami Herald) – At the bottom of the Everglades along the mouth of the Shark River, a towering mangrove forest stands in a place few people outside anglers and researchers ever see: at the edge of a vast shallow bay where the salty sea and freshwater marshes conspired […]
By Claire Salisbury14 February 2017 (Mongabay) – From the Amazon Basin to boreal forests, and from the Mekong to the Himalayan foothills, rivers worldwide are being targeted for major new dams in a global hydropower boom that also aims to supply drinking water to exploding human populations and to facilitate navigation on the planet’s rivers; […]
10 February 2017 (Stockholm Resilience Centre) – A paper recently published in the journal The Anthropocene Review puts the current rate of change of Earth’s life support system in the context of the last 4-billion-year evolution of the biosphere. The paper, which is written by the centre’s Owen Gaffney and senior research fellow Will Steffen, […]
