The bulk of the research took place in the Beaufort and Chukchi seas in summer and A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, a new study from NASA shows. The current is part of a delicate Arctic environment that is now flooded with fresh water, an effect of human-caused climate change. Using 12 years of satellite data, scientists have measured how this circular current, called the Beaufort Gyre, has precariously balanced an influx of unprecedented amounts of cold, fresh water — a change that could alter the currents in the Atlantic Ocean and cool the climate of Western Europe. The Beaufort Gyre keeps the polar environment in equilibrium by storing fresh water near the surface of the ocean.

By University of Gothenburg April 9, With the help of the uncrewed submarine Ran that made its way under Thwaites glacier front, the researchers have made a number of new discoveries. We plan to build on these exciting findings with further missions under the ice next year. The submersible has, among other things, measured the strength, temperature, salinity, and oxygen content of the ocean currents that go under the glacier. The ice sheet in West Antarctica accounts for about ten percent of the current rate of sea level rise; but also the ice in West Antarctica holds the most potential for increasing that rate because the fastest changes worldwide are taking place in the Thwaites Glacier.
Celebrating 20 years of improving harmful algal bloom research with citizen science. NOAA is moving into the digital age by phasing out paper nautical charts over five years. EJ Van Den Ameele, chief of Coast Survey's marine chart division, to learn how this transition will affect mariners and why electronic charts offer many advantages over paper.
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris, cause ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute to greenhouse gas emissions. The best known of these is the Great Pacific garbage patch which has the highest density of marine debris and plastic, visible from space in certain weather conditions.
