Meltwater as a Local Source of Ice Nucleating Particles in the Central Arctic Summer

Geophysical Research Letters
Identifying sources of ice nucleating particles (INPs) in the central Arctic is important for understanding controls on the phase of Arctic mixed‐phase clouds (AMPCs).

Sea ice meiofauna distribution on local to pan‐Arctic scales

Ecology and Evolution, 2018
Arctic sea ice provides microhabitats for biota that inhabit the liquid‐filled network of brine channels and the ice–water interface. We used meta‐analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in

Improvement of Ice Surface Temperature Retrieval by Integrating Landsat 8/TIRS and Operation IceBridge Observations

Remote Sensing, 2023
Accurate retrieval of ice surface temperature (IST) over the Arctic ice-water mixture zone (IWMZ) is significantly essential for monitoring the change of the polar sea ice environment.

Automatic detection of Arctic polynyas using hybrid supervised-unsupervised deep learning [PDF]

The Cryosphere
Polynyas are open water or thin-ice areas within the ice pack. They play a crucial role for the Earth system, from deep water to cloud formation, causing large gas exchanges, and acting as hotspots for marine life.

Oil tanker under ice loadings

Scientific Reports, 2023
As a result of global warming, the area of the polar pack ice is diminishing, making merchant travel more practical. Even if Arctic ice thickness reduced in the summer, fractured ice is still presenting operational risks to the future navigation.

CLIMATE CHANGE AT HIGH LATITUDES: AN ILLUMINATING EXAMPLE

Zygon, 2018
A striking example is presented of a newly observed phenomenon in the ice‐covered Arctic Ocean that appears to be a consequence of changes in the physical forcing.

Unprecedented Beaufort Sea ice loss in late summer 2021 and its relationship to an extended period of unusually stormy weather

Environmental Research Letters
Previous case studies have linked cyclone-induced atmospheric forcing and/or upper-ocean processes to notable Arctic sea ice loss events in the summers of 2012 and 2016.

Seasonal and spatial variations in sea ice kinematics and their response to storms in the Arctic Transpolar Drift region in 2021–2022

Journal of Glaciology
Sea ice outflow through the Transpolar Drift (TPD) is essential in Arctic sea ice loss. Twenty-four buoys deployed in the Arctic Ocean during the summer of 2021 were used to analyse sea ice kinematics and deformation across the pack ice zone (PIZ) and ...

Environmental drivers of under-ice phytoplankton bloom dynamics in the Arctic Ocean

Elementa: Science of the Anthropocene, 2020
The decline of sea-ice thickness, area, and volume due to the transition from multi-year to first-year sea ice has improved the under-ice light environment for pelagic Arctic ecosystems.

Culturable diversity of Arctic phytoplankton during pack ice melting [PDF]

Elementa: Science of the Anthropocene, 2019
Massive phytoplankton blooms develop at the Arctic ice edge, sometimes extending far under the pack ice. An extensive culturing effort was conducted before and during a phytoplankton bloom in Baffin Bay between April and July 2016. Different isolation strategies were applied, including flow cytometry cell sorting, manual single cell pipetting, and ...
