Permafrost coasts make up about one third of the Earth's total coastline. As a result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the Arctic Ocean. A new study published in the journal Geophysical Research Letters now shows that large amounts of carbon dioxide are potentially being produced along these eroding permafrost coastlines in the Arctic.
A study by researchers at Woods Hole Oceanographic Institution (WHOI) shows that the microbial communities inside whales may play an important role in the digestion of one of the ocean's most abundant carbon-rich lipids, known as a wax ester.
The European Research Council ERC has awarded an 11 million Euro Synergy grant called Deep Purple to Liane G. Benning at the GFZ German Research Centre for Geosciences in Potsdam, Germany, Alexandre Anesio at Aarhus University, Denmark, and Martyn Tranter at University of Bristol, UK. Their common goal is to examine over the next six years (starting in 2020) the role of glacier algae in progressively darkening the Greenland Ice Sheet surface in a warming climate.
Stormquakes are a phenomenon characterized by seismic activity originating at the ocean floor due to powerful storms. Heavy storms, like hurricanes or nor'easters, can create seismic waves as large as magnitude 3.5 quakes. These tremors caused by the effects of storms on the seafloor are what researchers call stormquakes. Catherine de Groot-Hedlin, who was part of the group that first observed stormquakes, will discuss their properties and meteorological significance at the 178th ASA Meeting.
Researchers from Kiel University (CAU), in cooperation with the NORe museum association for the North and Baltic Sea region and the Senckenberg Research Institute and Natural History Museum in Frankfurt, have managed to shine some light on the decline in numbers of the European oyster. They have concluded that the occurrence of the invasive American slipper limpet (Crepidula fornicata) is not one of the main causes for the European oyster dying out -- unlike previously assumed.
At a time when ocean noise is receiving increased global attention, researchers at Oregon State University have developed an effective method to use an underwater robotic glider to measure sound levels over broad areas of the sea.
