Arctic Ocean surface geostrophic circulation 2003–2014 [PDF]

The Cryosphere, 2017
Monitoring the surface circulation of the ice-covered Arctic Ocean is generally limited in space, time or both. We present a new 12-year record of geostrophic currents at monthly resolution in the ice-covered and ice-free Arctic Ocean derived from ...

Algal Hot Spots in a Changing Arctic Ocean: Sea-Ice Ridges and the Snow-Ice Interface

Frontiers in Marine Science, 2018
During the N-ICE2015 drift expedition north-west of Svalbard, we observed the establishment and development of algal communities in first-year ice (FYI) ridges and at the snow-ice interface.

The Arctic Summer Cloud Ocean Study (ASCOS): overview and experimental design [PDF]

Atmospheric Chemistry and Physics, 2014
The climate in the Arctic is changing faster than anywhere else on earth. Poorly understood feedback processes relating to Arctic clouds and aerosol–cloud interactions contribute to a poor understanding of the present changes in the Arctic climate system,

Low Density of Top Predators (Seabirds and Marine Mammals) in the High Arctic Pack Ice

Scientifica, 2016
The at-sea distribution of top predators, seabirds and marine mammals, was determined in the high Arctic pack ice on board the icebreaker RV Polarstern in July to September 2014. In total, 1,620 transect counts were realised, lasting 30 min each.

Ice-tethered observational platforms in the Arctic Ocean pack ice

IFAC-PapersOnLine, 2016
Abstract: The Arctic Ocean faces rapid climate change, which impacts both physical and biological components of the marine ecosystem. Due to complicated and costly logistics inherent to sampling ice-covered areas, most studies conducted in the Arctic are based on relatively short-term sampling (weeks to months) centered around the minimum ice season.

A red tide in the pack ice of the Arctic Ocean [PDF]

Scientific Reports, 2019
AbstractIn the Arctic Ocean ice algae constitute a key ecosystem component and the ice algal spring bloom a critical event in the annual production cycle. The bulk of ice algal biomass is usually found in the bottom few cm of the sea ice and dominated by pennate diatoms attached to the ice matrix.

Assessing the representation of Arctic sea ice and the marginal ice zone in ocean–sea ice reanalyses [PDF]

The Cryosphere
The recent development of data-assimilating reanalyses of the global ocean and sea ice enables a better understanding of the polar region dynamics and provides gridded descriptions of sea ice variables without temporal and spatial gaps.

Arctic marginal ice zone interannual variability and change point detection using two definitions (1983–2022)

Environmental Research Letters, 2023
The ongoing decline in Arctic sea ice extent and thickness underscores the scientific significance of monitoring the marginal ice zone (MIZ), a transitional region between the open ocean and pack ice.

Estimation Method for Ice load of Managed Ice in an Oblique Condition

한국해양공학회지, 2018
Recently, as sea ice in the Arctic has been decreasing due to global warming, it has become easier to develop oil and gas resources buried in the Arctic region.

Spatial and Temporal Variations in the Extent and Thickness of Arctic Landfast Ice

Remote Sensing, 2019
Analyses of landfast ice in Arctic coastal areas provide a comprehensive understanding of the variations in Arctic sea ice and generate data for studies on the utilization of the Arctic passages.
