ASTER-Derived High-Resolution Ice Surface Temperature for the Arctic Coast
Ice surface temperature (IST) controls the rate of sea ice growth and the heat exchange between the atmosphere and ocean. In this study, high-resolution IST using the Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) thermal infrared

New insight into the influence of the Greenland high on summer Arctic sea ice
The Greenland high (GL-high) coincides with a local center of action of the summer North Atlantic Oscillation and is known to have significant influence on Greenland ice sheet melting and summer Arctic sea ice. However, the mechanism behind the influence

Prediction of Arctic Sea Ice Concentration Using a Fully Data Driven Deep Neural Network
The Arctic sea ice is an important indicator of the progress of global warming and climate change. Prediction of Arctic sea ice concentration has been investigated by many disciplines and predictions have been made using a variety of methods.

The early twentieth century warming and winter Arctic sea ice [PDF]
The Arctic has featured the strongest surface warming over the globe during the recent decades, and the temperature increase has been accompanied by a rapid decline in sea ice extent.

Classification of sea ice types in Sentinel-1 synthetic aperture radar images [PDF]
A new Sentinel-1 image-based sea ice classification algorithm using a machine-learning-based model trained in a semi-automated manner is proposed to support daily ice charting.

Optimization of the k-nearest-neighbors model for summer Arctic Sea ice prediction
The Arctic sea ice plays a significant role in climate-related processes and has a considerable effect on humans, however accurately predicting the Arctic sea ice concentration is still challenging.

Unraveling the Arctic Sea Ice Change since the Middle of the Twentieth Century
Changes in Arctic sea ice since the middle of the last century are explored in this study. Both observations and climate model simulations show an overall sea ice expansion during 1953–1970 but a general sea ice decline afterward. Anthropogenic aerosols,

Bacteria and viruses in Arctic Sea ice
We studied vertical distribution of bacteria and viruses in different layers of the Arctic sea ice drilled at the North Pole. The sampled multi-year ice was characterized by uneven vertical distribution of bacterial abundance. This characteristic varied within the range of 8±1.2 ×103 to 95±2.6 ×103 cells ml-1. The average bacterial abundance was 28±2.9×
