Models may help reduce bycatch from longline fishing
Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after becoming snagged or entangled in longline fishing gear. Models developed by a Duke-led research team may help reduce the threat by giving regulatory agencies a new tool to predict the month-by-month movements of longline fleets on the high seas and determine where and when by-catch risks are greatest.

The anemonefish is more familiarly known as the clownfish, as its bright coloration reminds of the face painting of a clown. The striking and unique coloration consists of white stripes on an orange background, but its biological function has remained a mystery thus far. Now, a study by the researchers of the University of Turku and the University of Western Australia has revealed new information on the coloration of the fish. (2018-08-06)

Arctic cyclone limits the time-scale of precise sea-ice prediction in Northern Sea Route?
Climate change has accelerated sea-ice retreat in the Arctic Ocean, leading to new opportunities for summer commercial maritime navigation along the Northern Sea Route. International researchers led by Japan's National Institute of Polar Research demonstrated a new system for forecasting sea-ice thickness in early summer in the East Siberian Sea. The system was accurate up to 3 days ahead, representing high potential for use in operational maritime navigation of the Northern Sea Route. (2018-08-01)

The results, published in the current issue of PNAS, could lead to better ways to control sea lampreys. (2018-08-01)

Scientists draw new connections between climate change and warming oceans
Earth scientists exploring how ocean chemistry has evolved found similarities between an event 55 million years ago and current predicted trajectories of planet temperatures, with regards to inputs of CO2 into the atmosphere and oxygen levels in the oceans. As the oceans warm, oxygen decreases while hydrogen sulfide increases, making the oceans toxic and putting marine species at risk. (2018-08-01)

Fishing fleets travelling further to catch fewer fish
Industrial fishing fleets have doubled the distance they travel to fishing grounds since 1950, which means that they are now able to reach 90 percent of the global ocean, but are catching only a third of what they did 65 years ago per kilometer traveled. (2018-08-01)

Glaciers in East Antarctica also 'imperiled' by climate change, UCI researchers find
A team of scientists from the University of California, Irvine has found evidence of significant mass loss in East Antarctica's Totten and Moscow University glaciers, which, if they fully collapsed, could add 5 meters (16.4 feet) to the global sea level. (2018-07-26)

Great Barrier Reef reveals rapid changes of ancient glaciers
New analysis of the first Great Barrier Reef samples covering the time 22,000 years ago to 19,000 years ago finally adds detail to the poorly understood Last Glacial Maximum (27,000 to 20,000 years ago), providing valuable insights for models of climate and ice sheet dynamics. 'Current models of glacier dynamics may be too conservative. The possibility of rapid increases or decreases in sea level should be considered,' said UTokyo's Professor Yusuke Yokoyama. (2018-07-25)

NE Australian marine heatwave shakes up coral reef animal populations
Research published today in Nature describes upheaval among fish and invertebrate communities after a marine heatwave hit Australia's Great Barrier Reef and Coral Sea in early 2016. The IMAS-led study analysed data collected across these areas by the Reef Life Survey (RLS) citizen science program. It identified important changes in reef-animal communities that may affect the resilience of coral reefs, potentially reducing the capacity of corals to rebuild after mass bleaching. (2018-07-25)

Vessel tracking exposes the dark side of trading at sea
Transshipment -- exchanging seafood, crew or supplies between boats at sea -- is common in many fisheries, but it creates opportunity for illegal activity involving drugs and people. This first large-scale analysis of transshipment events exposes the potential extent of the unmanaged exchange of goods at sea. The study provides first ever public view of the extent to which these exchanges could be occurring, showing the need for a global collaboration to improve fisheries management (2018-07-23)

Texas A&M study: Sahara dust may make you cough, but it's a storm killer
The bad news: Dust from the Sahara Desert in Africa -- totaling a staggering 2 to 9 trillion pounds worldwide -- has been almost a biblical plague on Texas and much of the Southern United States in recent weeks. The good news: the same dust appears to be a severe storm killer. (2018-07-20)

New study puts a figure on sea-level rise following Antarctic ice shelves' collapse
Scientists have shown how much sea level would rise if Larsen C and George VI, Antarctic ice shelves at risk of collapse, were to break up. While Larsen C has received much attention due to the break-away of a trillion-tonne iceberg from it last summer, its collapse would contribute only a few millimetres to sea-level rise. The break-up of the smaller George VI Ice Shelf would have a much larger impact. The research is published today in The Cryosphere. (2018-07-19)

Reconstruction of Arctic Barents-Kara sea ice extent changes over the last millennium
The Arctic Barents-Kara Sea is considered as one of the cradles for cold waves over the Eurasian continent, and it's a key sea sector that is closely connected with cold waves over Eurasia.
