Daily Arctic Sea Ice Extent Images are of fine resolution (at 2.25km) than any available product for the Arctic region and are disseminated at the VEDAS (Visualization of Earth observation Data and Archival System) portal of SAC from 2016 onwards....
Researchers found thatduring the last interglacial period many shallow68_(pool) of waterformed on the surfaceof the Arctic sea ice during spring and summer These pools known as met ponds, played akey role in the melting of the sea ice. This is because69 there are larger areas of meltponds,...
Using 12 years of satellite data,NASAscientists have measured how the influx of cold, fresh water is affecting the Beaufort Gyre, a major Arctic current. 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...
The interval was then reduced by shrinking the STs thresholds to the halfway point between the current interval boundary and to and the estimation of SC updated until only one other point remained. Dates when CHN1s <= CHN1s(to) or with STs > Tmax were mapped as snow free. Dates when ...
indicator of the health of the Arctic. It is important as thicker ice acts as an insulating blanket, stopping the ocean from warming up the atmosphere in winter, and protecting the ocean from the sunshine in summer. Thinner ice is also less likely to survive during the Arctic summer melt....
So why after all those dire predictions of doom and devastation has Arctic sea ice cover come roaring back so quickly over the last few years? Nobody knows – apparently not one scientist on the planet can tell you, writes Willis Eschenbach in a short essay for the climate alarmism...
Reports from fishermen, seal hunters and explorers all point to a radical change in climate conditions in the Arctic zone. Expeditions report that scarcely any ice has been met with as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still ...
sea ice thickness; thermodynamic parameters; neural network; Arctic1. Introduction Sea ice is a crucial component of the Earth’s cryosphere. Sea ice covers the sea surface and the energy transfer between the ocean–ice–atmosphere is the main reason for its freezing and melting. In winter, ...
To meet the increasing sailing demand of the Northeast Passage of the Arctic, a daily prediction model of sea ice concentration (SIC) based on the convolutional long short-term memory network (ConvLSTM) algorithm was proposed in this study. Previously, similar deep learning algorithms (such as co...
Sometimes the tedium of trading can be thought of as waiting day after day in an ice house for the weather to turn favorable. Amundsen was a big proponent of routines, small incentive contests and the shunning of idleness during his arctic times with his men–much here to think of and use...
