Deepwater Horizon spill: Much of the oil at bottom of the sea

This item was filled under Climate
Due to its unprecedented scope, the damage assessment caused by the 2010 Deepwater Horizon spill in the Gulf of Mexico has been a challenge. One unsolved puzzle is the location of 2 million barrels of submerged oil thought to be trapped in the deep ocean....

Penguin chick weights connected to local weather conditions

This item was filled under Climate
Oceanographers have reported a connection between local weather conditions and the weight of Adélie penguin chicks. Adélie penguins are an indigenous species of the West Antarctic Peninsula (WAP), one of the most rapidly warming areas on Earth. Since 1950, the average annual temperature in the Antarctic Peninsula has increased 2 degrees Celsius on average, and 6 degrees Celsius during winter....

Climate change caused by ocean, not just atmosphere

This item was filled under Climate
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. A new study reveals another equally important factor in regulating Earth's climate. Researchers say the major cooling of Earth and continental ice build-up in the Northern Hemisphere 2.7 million years ago coincided with a shift in the circulation of the ocean....

Law of the Sea authorizes animal tagging research without nations’ consent, experts say

This item was filled under Climate
Scientists who study migratory marine animals can rarely predict where the animals' paths will lead. Researchers now argue that coastal nations don't have precedent under the law of the sea to require scientists to seek advance permission to remotely track tagged animals who may enter their waters. Requiring advance consent undermines the goals of the law, which is meant to encourage scientific research for conservation of marine animals....

Bodies at sea: Ocean oxygen levels may impact scavenger response

This item was filled under Climate
An ocean's oxygen levels may play a role in the impact of marine predators on bodies when they are immersed in the sea, according to researchers, who deployed a trio of pig carcasses into Saanich Inlet off Vancouver Island and studied them using an underwater camera via the internet....

Desert streams: Deceptively simple

This item was filled under Climate
Volatile rainstorms drive complex landscape changes in deserts, particularly in dryland channels, which are shaped by flash flooding. Paradoxically, such desert streams have surprisingly simple topography with smooth, straight and symmetrical form that until now has defied explanation....

Top marine scientists call for action on ‘invisible’ fisheries

This item was filled under Climate
To protect our oceans from irreversible harm, governments, conservationists, and researchers around the world must address the enormous threat posed by unregulated and destructive fisheries, say top marine scientists....

A New Perspective on U.S. Great Lakes

This item was filled under News
Any geography student who's viewed a map of the United States has surely marveled at the vast expanse of the nation's Great Lakes, which contain nearly 20 percent of the Earth's surface water. To stand on the shore of any one of these freshwater inland seas--Superior, Michigan, Huron, Erie, or Ontario--is to gaze across boundless waters to a distant horizon. Now, NOAA's Office for Coastal Management provides another perspective on these impressive water bodies with its new Lake Level Viewer for the U.S. Great Lakes.

Study of mitochondrial DNA reveals how loggerhead turtle reached Mediterranean

This item was filled under Climate
To date, it was thought that the loggerhead turtle arrived to the Mediterranean from North America and the Caribbean after the last glacial period. However, latest scientific studies show that this marine species colonized the Mediterranean between 20,000 and 200,000 years ago, so the colonization event took place before the last glacial period....
