Study of the impact of ice formation in leads upon the sea ice pack mass balance using a new frazil and grease ice parameterisation [PDF]

open access: yes, 2015
Leads are cracks in sea ice that often form due to deformation. During winter months leads expose the ocean to the cold atmosphere resulting in supercooling and the formation of frazil ice crystals within the mixed layer.

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

open access: yesThe 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.

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

open access: yesRemote 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.

Winter sea ice export from the Laptev Sea preconditions the local summer sea ice cover and fast ice decay [PDF]

open access: yesThe Cryosphere, 2017
Ice retreat in the eastern Eurasian Arctic is a consequence of atmospheric and oceanic processes and regional feedback mechanisms acting on the ice cover, both in winter and summer.

Impact of rheology on probabilistic forecasts of sea ice trajectories: application for search and rescue operations in the Arctic [PDF]

open access: yes, 2018
We present a sensitivity analysis and discuss the probabilistic forecast capabilities of the novel sea ice model neXtSIM used in hindcast mode. The study pertains to the response of the model to the uncertainty on winds using probabilistic forecasts of ...

Sea-Ice Morphology Change in the Canada Basin Summer: 2006–2015 Ship Observations Compared to Observations From the 1960s to the Early 1990s

open access: yesFrontiers in Earth Science, 2018
An ice watch, encompassing visual observation of sea ice conducted from the ship's bridge, is typically performed on sea-ice oriented research cruises.

Transition in the fractal geometry of Arctic melt ponds [PDF]

open access: yesThe Cryosphere, 2012
During the Arctic melt season, the sea ice surface undergoes a remarkable transformation from vast expanses of snow covered ice to complex mosaics of ice and melt ponds.

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

open access: yes한국해양공학회지, 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.

Measurements of bubble size spectra within leads in the Arctic summer pack ice [PDF]

open access: greenOcean Science, 2010
Abstract. The first measurements of bubble size spectra within the near-surface waters of open leads in the central Arctic pack ice were obtained during the Artic Summer Cloud-Ocean Study (ASCOS) in August 2008 at 87–87.6° N, 1–11° W. A significant number of small bubbles (30–100 μm diameter) were present, with concentration decreasing rapidly with ...

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

open access: yesPolar 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.
