Winter storms accelerate the demise of sea ice in the Atlantic sector of the Arctic Ocean [PDF]

, 2019
International audienceA large retreat of sea-ice in the 'stormy' Atlantic sector of the Arctic ocean has become evident through a series of record minima for the winter maximum sea-ice extent since 2015.

Sea-ice meiofauna biomass, carbon demand, and secondary production in Arctic pack ice north of Svalbard during the Polarstern expedition PS92 in spring 2015

, 2021
We investigated the biomass, carbon demand, and secondary production of sea-ice meiofauna (here heterotrophs >10μm) at eight ice stations on Arctic pack ice north of Svalbard. Sampling was conducted during spring 2015 by sea-ice coring. The biomass (µgCm-

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.

Improving the spatial distribution of modeled Arctic sea ice thickness

, 2005
The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the

Hydraulic controls of summer Arctic pack ice albedo [PDF]

Journal of Geophysical Research: Oceans, 2004
Linkages between albedo, surface morphology, melt pond distribution, and properties of first‐year and multiyear sea ice have been studied at two field sites in the North American Arctic between 1998 and 2001. It is shown that summer sea‐ice albedo depends critically on surface melt‐pond hydrology, controlled by melt rate, ice permeability, and ...

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.

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.

Vertical profiling of aerosol particles and trace gases over the central Arctic Ocean during summer [PDF]

Atmospheric Chemistry and Physics, 2013
Unique measurements of vertical size-resolved aerosol particle concentrations, trace gas concentrations and meteorological data were obtained during the Arctic Summer Cloud Ocean Study (ASCOS, www.ascos.se), an International Polar Year project aimed at ...

The number and distribution of polar bears in the western Barents Sea

Polar Research, 2017
Polar bears have experienced a rapid loss of sea-ice habitat in the Barents Sea. Monitoring this subpopulation focuses on the effects on polar bear demography.
