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 ...

Environmental drivers of under-ice phytoplankton bloom dynamics in the Arctic Ocean

open access: yesElementa: Science of the Anthropocene, 2020
The decline of sea-ice thickness, area, and volume due to the transition from multi-year to first-year sea ice has improved the under-ice light environment for pelagic Arctic ecosystems.

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.

Increasing Mobility of High Arctic Sea Ice Increases Marine Hazards Off the East Coast of Newfoundland [PDF]

open access: yes, 2020
Heavy ice conditions along Canada’s east coast during spring 2017 presented hazardous conditions for the maritime industry and required the Canadian Coast Guard to pull its research icebreaker, CCGS Amundsen, off its scientific cruise to provide ice ...

The progress in the study of Arctic pack ice ecology [PDF]

open access: yes, 2004
The sea ice community plays an important role in the Arctic marine ecosystem. Because of the predicted environmental changes in the Arctic environment and specifically related to sea ice, the Arctic pack ice biota has received more attention in recent ...

Quantitative Use of Satellite Vidicon Data for Delimiting Sea Ice Conditions [PDF]

open access: yes, 1973
Although television pictures from Earth satellites have been used for over ten years to detect major sea ice features, direct photo-interpretation methods have been supplemented with a fully-automated technique employing Composite Minimum Brightness (CMB)

Overview of the MOSAiC expedition: Snow and sea ice [PDF]

open access: yes, 2022
Year-round observations of the physical snow and ice properties and processes that govern the ice pack evolution and its interaction with the atmosphere and the ocean were conducted during the Multidisciplinary drifting Observatory for the Study of ...

Vertical sonar beam width and scanning behavior of wild belugas (Delphinapterus leucas) in West Greenland.

open access: yesPLoS ONE, 2021
Echolocation signals of wild beluga whales (Delphinapterus leucas) were recorded in 2013 using a vertical, linear 16-hydrophone array at two locations in the pack ice of Baffin Bay, West Greenland.

Taking stock of arctic sea ice and climate [PDF]

open access: yes, 2009
The relationship among the cause-and-effect of the Arctic atmosphere, sea ice, and ocean is discussed. The increased vulnerability of the Arctic system to anomalous atmospheric forcing can be argued from the perspective that recent ice loss is the result
