Around 2005, southern right whale calves off the coast of Argentina began dieing off at an unprecented rate (from 6 per year in 2005 to around 65 per year from 2005 to 2014). Scientists have never determined the cause until a recent Marine Mammal Science paper named a likely culprit: toxic algae blooms. Read about the new findings on EurekAlert!.

California 2100: More frequent and more severe droughts and floods likely
A study published in Nature Communications suggests that the weather patterns known as El Nino and La Nina could lead to at least a doubling of extreme droughts and floods in California later this century.

Beavers take a chunk out of nitrogen in Northeast rivers
Beavers, once valued for their fur, may soon have more appreciation in the Northeastern United States. There they are helping prevent harmful levels of nitrogen from reaching the area's vulnerable estuaries. By creating ponds that slow down the movement of water, they aid in removing nitrogen from the water.

This fish out of water cools down fast: Study
The tiny mangrove rivulus fish cools down by jumping out of water, according to a new study from the University of Guelph. The fish lives in tropical climates, and when the water is warm, will jump out to cool its body temperature down by air-chilling itself. This is an example of evaporative cooling. As temperatures warm in this area due to climate change, this could happen more often.

This week from AGU: Arctic sea ice, ocean circulation, sea level rise & research papers
Anticipated declines in human-produced aerosols could have a significant effect on Arctic sea ice cover over the remainder of the 21st century, accounting for up to 40 percent of the decline in sea ice extent that could occur in the region by 2100, shows a new Geophysical Research Letters study.

Nano power grids between bacteria
Microorganisms in the sea organize their power supply via tiny power-cables, thus oxidizing the greenhouse gas methane.

Analysts see nations' misuse of 'rational use' when it comes to fishing rights
The term 'rational use,' as applied to fishing rights in Antarctic waters, has been misused by certain countries, an analysis by a team of researchers has concluded. Its work, which comes ahead of the 34th international convention where these matters are negotiated, posits that some nations mistakenly see the term as a license for unrestricted fishing.

EMB Brussels event to highlight the importance of ocean research in addressing climate change
A scientific forum, The Ocean-Climate Nexus, organized by the European Marine Board (EMB), will be held at the European Parliament in Brussels on Oct. 21, 2015 at 16.00. The special parliament event is being hosted by former EMB vice-Chair, MEP Ricardo Serrao Santos.

Unmanned NOAA hexacopter monitors health of endangered Southern Resident killer whales
A NOAA Fisheries research team flying a remotely operated hexacopter in Washington's San Juan Islands in September collected high-resolution aerial photogrammetry images of all 81 Southern Resident killer whales that showed the endangered whales in robust condition and that several appear to be pregnant.

Prawns reveal the secrets of innovation
Small and hungry prawns are more likely to be resourceful in the face of adversity than their less desperate counterparts according to new research published today in the journal PLOS ONE. However the study found that size and hunger have different effects depending on whether the prawns are acting alone or in a group. Small individuals were more likely to innovate when alone, but when in a group, size didn't matter and it was the hungry prawns that tended to be most resourceful.

Formation of coastal sea ice in North Pacific drives ocean circulation and climate
An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing climate on regional and global scales. Coastal sea ice formation takes place on relatively small scales, however, and is not captured well in global climate models.
