Platelet Ice Under Arctic Pack Ice in Winter [PDF]
Geophysical Research Letters, 2020 The formation of platelet ice is well known to occur under Antarctic sea ice, where subice platelet layers form from supercooled ice shelf water. In the Arctic, however, platelet ice formation has not been extensively observed, and its formation and ...

Sympagic Fauna in and Under Arctic Pack Ice in the Annual Sea-Ice System of the New Arctic [PDF]
Frontiers in Marine Science, 2020 A strong decline and thinning of the Arctic sea-ice cover over the past five decades has been documented. The former multiyear sea-ice system has largely changed to an annual system and with it the dynamics of sea-ice transport across the Arctic Ocean ...

The operational determination of wind stress on the Arctic ice pack
, 1977 Abstract : The performance of routine FNWC sea level pressure analyses and forecasts in the Beaufort Sea is evaluated for driving an ice model. The geostrophic winds determined from the FNWC pressure fields are compared to geostrophic winds determined from the AIDJEX experiment observations.

A red tide in the pack ice of the Arctic Ocean [PDF]
Scientific Reports, 2019 In 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

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.

The seeding of ice algal blooms in Arctic pack ice: The multiyear ice seed repository hypothesis
Journal of Geophysical Research: Biogeosciences, 2017 During the Norwegian young sea ICE expedition (N‐ICE2015) from January to June 2015 the pack ice in the Arctic Ocean north of Svalbard was studied during four drifts between 83° and 80°N.

Oxygen fluxes beneath Arctic land-fast ice and pack ice: towards estimates of ice productivity [PDF]
Polar Biology, 2018 Sea-ice ecosystems are among the most extensive of Earth’s habitats; yet its autotrophic and heterotrophic activities remain poorly constrained. We employed the in situ aquatic eddy-covariance (AEC) O2 flux method and laboratory incubation techniques ...

Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ice [PDF]
Scientific Reports, 2017 The Arctic icescape is rapidly transforming from a thicker multiyear ice cover to a thinner and largely seasonal first-year ice cover with significant consequences for Arctic primary production.

Studies of the Mass Budget of Arctic Pack-Ice Floes [PDF]
Journal of Glaciology, 1965 AbstractThe processes of melting, freezing, precipitation, evaporation and condensation were considered in the computation of the mass budget of an ice floe in the northern Chukchi Sea. It was bound that condensation and evaporation contribute negligible amounts, and that melting accounted for the largest loss from the upper surface of the floe.
