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!.

Video: Electric eels may be some of the most sophisticated marine predators in the animal kingdom, according to a recent Current Biology paper by Vanderbilt University researchers. Check out video of them in action here and read about their specialized hunting techniques on EurekAlert!.

NASA sees Tropical Storm Patricia's lopsided heavy rains along Mexican coast
NASA's GPM satellite saw that the western side of Tropical Storm Patricia was packing most of the storm's moderate and heavy rainfall when it passed overhead in space. Patricia was close to the coast of western Mexico, and triggered warnings and watches. Patricia intensified into a hurricane on Oct. 22.

Fish farming gobbles up phosphorus
Fish farming is the largest source of phosphorus emissions in Norway, generating about 9,000 tonnes a year. Finding ways to reuse the waste from the fish farming industry could cut consumption of this important and increasingly scarce resource.

Gear, not geoducks, impacts ecosystem if farming increases
The equipment used to farm geoducks, including PVC pipes and nets, might have a greater impact on the Puget Sound food web than the addition of the clams themselves. That's one of the findings of the first major scientific study to examine the broad, long-term ecosystem effects of geoduck aquaculture in Puget Sound.

Ocean heat content reveals secrets of fish migration behaviors
Researchers at the University of Miami Rosenstiel School of Marine and Atmospheric Science developed a new method to estimate fish movements using ocean heat content images, a dataset commonly used in hurricane intensity forecasting. With Atlantic tarpon as the messenger, this is the first study to quantitatively show that large migratory fishes, such as yellowfin and bluefin tunas, blue and white marlin, and sailfish have affinities for ocean fronts and eddies.

Antarctic species threatened by willful misinterpretation of legal treaty
Some countries argue that setting up marine protected areas in the Southern Ocean would interfere with their right to 'rational use' of natural resources.

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.
