The early twentieth century warming and winter Arctic sea ice [PDF]
The Cryosphere, 2012 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.

Oceanography, 2022 Our understanding of Arctic sea ice and its wide-ranging influence is deeply rooted in observation. Advancing technologies have profoundly improved our ability to observe Arctic sea ice, document its processes and properties, and describe atmosphere-ice-ocean interactions with unprecedented detail.

Optimization of the k-nearest-neighbors model for summer Arctic Sea ice prediction
Frontiers in Marine Science, 2023 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.

Classification of sea ice types in Sentinel-1 synthetic aperture radar images [PDF]
The Cryosphere, 2020 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.

Unraveling the Arctic Sea Ice Change since the Middle of the Twentieth Century
Geosciences, 2023 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
Oceanology, 2018 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×

Improving Met Office seasonal predictions of Arctic sea ice using assimilation of CryoSat-2 thickness [PDF]
The Cryosphere, 2018 Interest in seasonal predictions of Arctic sea ice has been increasing in recent years owing, primarily, to the sharp reduction in Arctic sea-ice cover observed over the last few decades, a decline that is projected to continue.

Robust Arctic warming caused by projected Antarctic sea ice loss
Environmental Research Letters, 2020 Over the coming century, both Arctic and Antarctic sea ice cover are projected to substantially decline. While many studies have documented the potential impacts of projected Arctic sea ice loss on the climate of the mid-latitudes and the tropics, little

Remote Sensing, 2023 With global warming, the decrease in sea ice creates favorable conditions for Arctic activities. Sea surface temperature (SST) is not only an important driven factor of sea ice concentration (SIC) changes but also an important medium of the ocean ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
