Are sea ice changes impacting weather patterns in non-Arctic regions? A new study demonstrates that the recent cooler temperature trends may simply be a consequence of random, chaotic variability of the atmosphere, and a warming trend may eventually resume.
When a model simulates a larger sea-ice decline, how does the circulation outside the Arctic change? A new study addressed this question and suggested a more accurate winter Arctic sea-ice projection could be useful for constraining projections of winter Eurasian climate.
Over the past decades the Arctic has lost 65% of its sea ice volume. The atmosphere above the Arctic has been rapidly warming and moistening at the same time. The Arctic might be perceived as a remote and sparsely populated area, the changes there may be of relevance to the society in denser populated areas.
A significant amount of the methane naturally released into the atmosphere comes from the ocean. This has long puzzled scientists because there are no known methane-producing organisms near the ocean's surface. A team of MIT and University of Illinois researchers has made a discovery that could help to answer this 'ocean methane paradox.'
There's controversy in climate change research -- not whether climate change exists, but how the evidence is gathered and used to inform predictions. To help bring convergence to the field and potentially accelerate action, a special issue of the Advances in Atmospheric Sciences is highlighting recent scientific work.
NASA's Global Precipitation Measurement mission or GPM Core Observatory satellite passed over western India on Dec. 5, 2017 at (12:21 a.m. EST) 0521 UTC and found that the remnants of former Tropical Cyclone Ockhi has reached the coast.
A new paper by MBARI researchers Anela Choy, Steve Haddock, and Bruce Robison documents the first comprehensive study of deep-sea food webs, using hundreds of video observations of animals caught in the act of feeding off the Central California coast. The study shows that deep-sea jellies are key predators, and provides new information on how deep-sea animals interact with life near the ocean surface.
Marine invertebrates are impacted by the rising levels of underwater noise produced by humans, but the production of underwater noise is not only difficult to control, but the direct effect on marine invertebrates can be challenging to observe or measure. Researchers will present results on the use of a standing wave tube to simulate and measure the effects of anthropogenic noise on marine invertebrates at the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans.
Tropical Cyclone Ockhi is quickly weakening in the Arabian Sea and is expected to dissipate on Dec. 6 when it makes landfall in northwestern India. The Global Precipitation Measurement mission or GPM core satellite passed over Ockhi and looked at its rainfall as wind shear was affecting the storm.
Tropical Depression Dahlia was weakening into a remnant low pressure area when the Global Precipitation Measurement mission core satellite or GPM analyzed the storm's precipitation. GPM found the center devoid of rainfall and light rainfall to the east of center.
