Polarstern expedition: Autonomous underwater vehicle dives under the Arctic ice
The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association for the first time sent its Autonomous Underwater Vehicle (AUV) on an under-ice mission at about 79° North. The four-metre-long, torpedo shaped underwater vehicle was deployed from the research icebreaker Polarstern under heavy pack ice. The vehicle was subsequently recovered by helicopter.
Best hope for saving Arctic sea ice is cutting soot emissions, say researchers
Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new study. But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice before it all melts.
Marine biodiversity strongly linked to ocean temperature
Scientists have mapped and analyzed global biodiversity patterns for over 11,000 marine species ranging from tiny zooplankton to sharks and whales.
Marine phytoplankton declining: Striking global changes at the base of the marine food web linked to...
A new article reveals for the first time that microscopic marine algae known as phytoplankton have been declining globally over the 20th century. Phytoplankton forms the basis of the marine food chain and sustains diverse assemblages of species ranging from tiny zooplankton to large marine mammals, seabirds, and fish.
