What we commonly see accumulating at the sea surface is “less than the tip of the iceberg, maybe a half of 1% of the total,” says Erik Van Sebille, an oceanographer at Utrecht University in the Netherlands.
Plastic, Cigarette Butts Pollute Swiss Rivers & Lakes
The study, which took a “citizen science” approach to data collection, is the first of its kind in Switzerland. More than 150 trained volunteers participated. In total, they examined 95,971 pieces of litter collected on the shores of Swiss rivers and lakes.
New Research Documents Environmental Change Through Dolphin Skin Cells
“We documented for first time marked changes in the pelagic food web length in response to various natural and anthropogenic related stressors,” said lead author Rocio I. Ruiz-Cooley, formerly of NOAA Fisheries’ Southwest Fisheries Science Center and now at Moss Landing Marine Laboratories. “This tells us that the food web is very dynamic, and reveals changes with the ecosystem around it.”
Plastics Found Near North Pole
More than five trillion pieces of plastic are estimated floating on the surface of the world’s oceans. It has been claimed that there is now enough plastic to form a permanent layer in the fossil record.
Coral Reef Death Impacting Sea Levels
In the Florida Keys, the U.S. Virgin Islands and Maui, coral reef degradation has caused sea floor depths to increase as sand and other sea floor materials have eroded over the past few decades, the USGS study found. In the waters around Maui, the sea floor losses amounted to 81 million cubic meters of sand, rock and other material – about what it would take to fill up the Empire State Building 81 times, the researchers calculated.
Researchers Explains Coral Reef Bleaching
We now have a 2017 event, which is not quite as bad as 2016, but certainly worse than the first two events that we studied [in 1998 and 2002]. That is significant because it postpones any hope of recovery. The current bleaching occupies a different geographical footprint from last year, which is bad news because it means between last year and this year a much greater extent of the Great Barrier Reef has now been damaged. In 2017, the hot water was in the middle of the Great Barrier Reef, the central section; last year it was in the north.
Shocking Report on Global Seabird Decline
Some of the largest population declines, according to the report, include terns at 85.8 percent. Frigatebirds decline by up to 81.7 percent. Petrels declines followed at 79.6 percent, while cormorants and shags populations dropped by up to 73.6 percent.
Puget Sound Jellyfish Population Signifies Ecosystem Change
FRISCO — Biologists looking at 40 years of fisheries data from Puget Sound have documented a dramatic shift in marine species. Key fish in the food chain, like herring and smelt, have declined, while the number of jellyfish has increased… Read More ›
Phthalates Found in Aleutian Island Seabirds
The chemicals that Padula looks for in sea birds are called phthalates. They are a family of chemicals used to make plastic more flexible, and they can leach into the muscle and liver tissues of birds.
Padula found those chemicals in all of the birds she collected in the west Aleutians. But only some birds had visible pieces of plastic in their stomach.
Studying a Changing Arctic Ocean
Changes in the Arctic Ocean are so profound that the region is entering what amounts to “a new era”, according to Norwegian scientists. A switch from a permanent cover of thick ice to a new state where thinner ice vanishes… Read More ›
