Underwater acoustic localization of marine mammals and vehicles

Wed, 22 Nov 2017 00:00:00 EST

(IMDEA Networks Institute) Researchers at IMDEA Networks (Spain) in collaboration with University of Haifa (Israel) have developed an underwater acoustic system for the localization of marine mammals, underwater vehicles and other sound sources in the ocean, using no more than a single hydrophone (basically an underwater microphone) as a receiver.

Scientists find why CP El Niño is harder to predict than EP El Niño

Wed, 22 Nov 2017 00:00:00 EST

(Institute of Atmospheric Physics, Chinese Academy of Sciences) It's found that the skill scores for EP events were significantly better than those for CP events at all lead times. The possible reasons are related to the systematic forecast biases coming mostly from the prediction of CP events; and systematic error characterized by an overly warm eastern Pacific during the spring season, indicating a stronger spring prediction barrier for CP El Niño.

Wed, 22 Nov 2017 00:00:00 EST

(PLOS) Bowhead whales molt and rub on large rocks -- likely facilitating exfoliation -- in coastal waters in the eastern Canadian Arctic during late summer, according to a study published Nov. 22, 2017, in the open-access journal PLOS ONE by Sarah Fortune from University of British Columbia, Canada, and colleagues.

Scientists discover most blue whales are 'right-handed' -- except when they swim upward

Mon, 20 Nov 2017 00:00:00 EST

(Oregon State University) A team of scientists that used motion-sensing tags to track the movements of more than five dozen blue whales off the California coast discovered that most have a lateralization bias - in other words, they essentially are 'right-handed' or 'left-handed.'

Study urges global-change researchers to embrace variability

Wed, 15 Nov 2017 00:00:00 EST

(Virginia Institute of Marine Science) A new review article presents evidence that argues for a more nuanced approach to the design of global-change experiments -- one that acknowledges and purposefully incorporates the variability inherent in nature.

Pacific Island countries could lose 50-80 percent of fish in local waters under climate change

Wed, 15 Nov 2017 00:00:00 EST

(Nippon Foundation-Nereus Program) Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new Nippon Foundation-Nereus Program study published in Marine Policy. This area of the ocean is projected to be the most severely impacted by aspects of climate change.

Wed, 15 Nov 2017 00:00:00 EST

(NASA/Goddard Space Flight Center) The Global Precipitation Measurement mission or GPM core satellite provided data on rainfall over Vietnam from the remnants of former Tropical Storm Haikui.

Scripps scientists use photomosaic technology to find order in the chaos of coral reefs

Wed, 15 Nov 2017 00:00:00 EST

(University of California - San Diego) In a study published recently in Coral Reefs, scientists from the Scripps Institution of Oceanography at UC San Diego created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll using advanced imaging and digitization technology.

Shifting presence of North Atlantic right whales tracked with passive acoustics

Wed, 15 Nov 2017 00:00:00 EST

(NOAA Northeast Fisheries Science Center) A new study confirms what marine mammal researchers have suspected for a while: right whales use nearly the entire eastern seaboard during the winter, and they move around a lot more than was previously thought. How long they spend in some areas of their range has also changed in recent years.
