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

Culturable diversity of Arctic phytoplankton during pack ice melting [PDF]
Elementa: Science of the Anthropocene, 2020 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.

Status and trends in the structure of Arctic benthic food webs [PDF]
Polar Research, 2015 Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it is projected that the Arctic Ocean will become seasonally ice-free by 2040.

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 (H14CO3−, [3H] thymidine and [3H] leucine) to assess productivity in Arctic sea-ice using different ...

Under-ice fauna abundance of Arctic pack ice north of Svalbard during the Polarstern expedition PS92 in 2015 [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. Less sea ice is reaching the Fram Strait and more ice and ice-transported material is released in the

A Submarine Sonar Study of Arctic Pack Ice [PDF]
Journal of Glaciology, 1975 AbstractA continuous profile of the Arctic Ocean ice canopy from Spitsbergen to the North Pole was made with 48 kHz echo sounders mourned on a nuclear submarine. A semi-automatic digitizer was used to measure coordinates from the records at a frequency of about 1 000 points per linear kilometre of track.

Relating arctic pack ice stress and deformation under winter conditions [PDF]
Journal of Geophysical Research: Oceans, 2002 Together, thermodynamic and dynamic processes determine the thickness distribution of the ice cover on polar oceans, which governs the exchange of energy between the atmosphere and the ocean. Key to the dynamic processes is the mechanical behavior of the ice cover. During the Surface Heat Budget of the Arctic Ocean (SHEBA) field experiment, we deployed

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.
