Erosion May Transform The Arctic Food Chain

Erosion May Transform The Arctic Food Chain | Océan et climat, un équilibre nécessaire | Scoop.it
As climate change continues to grip the Arctic—causing the oceans to rise, permafrost to thaw and sea ice to melt—scientists believe they've discovered an unexpected consequence of the shifting landscape. Changes along the coastline are altering the composition of the Arctic Ocean, in ways that could fundamentally

New report calls for research to better understand, predict Gulf of Mexico's loop current system

New report calls for research to better understand, predict Gulf of Mexico's loop current system | Océan et climat, un équilibre nécessaire | Scoop.it
A new report calls for an international, multi-institutional comprehensive campaign of research, observation, and analysis activities that would help improve understanding and prediction of the Gulf of Mexico's Loop Current System (LCS). The position, strength, and structure of the LCS -- the dominant ocean circulation feature in the Gulf -- has major implications for oil and gas operations, hurricane intensity, coastal ecosystems, oil spill response, the fishing industry, tourism, and the region's economy.

The ocean is losing its breath -- here's the global scope: In broadest view yet of world's low oxygen, scientists reveal dangers and solutions

The ocean is losing its breath -- here's the global scope: In broadest view yet of world's low oxygen, scientists reveal dangers and solutions | Océan et climat, un équilibre nécessaire | Scoop.it
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 tenfold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms.

Scientists have uncovered the ocean conditions that support a massive summertime bloom of algae that spans 16 percent of the global ocean. Known as the Great Calcite Belt, this dense group of a microscopic phytoplankton, coccolithophores, can be seen in satellite images as turquoise swirls in the dark blue water of the Southern Ocean.

Melting Ice Could Mess Up Deep-Sea Chemistry

Melting Ice Could Mess Up Deep-Sea Chemistry | Océan et climat, un équilibre nécessaire | Scoop.it
Melting glaciers might be making ocean water more acidic, an unexpected finding that's given scientists new cause for concern. A new study published yesterday in the journal Nature Climate Change suggests surprising ways that climate change is drastically altering the water chemistry in deep seas—a process that may happen faster than researchers anticipated.
