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

Single-particle characterization of the high-Arctic summertime aerosol [PDF]
Atmospheric Chemistry and Physics, 2014 Single-particle mass-spectrometric measurements were carried out in the high Arctic north of 80° during summer 2008. The campaign took place onboard the icebreaker Oden and was part of the Arctic Summer Cloud Ocean Study (ASCOS).

Frost flower chemical signature in winter snow on Vestfonna ice cap, Nordaustlandet, Svalbard [PDF]
The Cryosphere, 2009 The chemistry of snow and ice cores from Svalbard is influenced by variations in local sea ice margin and distance to open water. Snow pits sampled at two summits of Vestfonna ice cap (Nordaustlandet, Svalbard), exhibit spatially heterogeneous soluble ...

Scaling aspects of the sea-ice-drift dynamics and pack fracture [PDF]
Ocean Science, 2007 A study of the sea-ice dynamics in the periods of time prior to and during the cycles of basin-wide fragmentation of the ice cover in the Arctic Ocean is presented. The fractal geometry of the ice-sheets limited by leads and ridges was assessed using the

Wave–sea-ice interactions in a brittle rheological framework [PDF]
The Cryosphere, 2021 As sea ice extent decreases in the Arctic, surface ocean waves have more time and space to develop and grow, exposing the marginal ice zone (MIZ) to more frequent and more energetic wave events.

Atmospheric highs drive asymmetric sea ice drift during lead opening from Point Barrow [PDF]
The Cryosphere, 2023 Throughout winter, the winds of migrating weather systems drive the recurrent opening of sea ice leads from Alaska's northernmost headland, Point Barrow.

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

A Study of the M-2 Tide in the Ice-Covered Arctic Ocean [PDF]
Modeling, Identification and Control, 1981 A model to study M2 tide propagation in the Arctic Ocean based on the equation of motion of the water and the pack ice, is considered. The mechanics of the ice floe interaction is described by the non-linear viscous constitutive loaw.

Variability and changes of Arctic sea ice draft distribution – submarine sonar measurements revisited [PDF]
The Cryosphere, 2011 Changes in the mean sea ice thickness and concentration in the Arctic are well known. However, quantitative information about changes in the ice thickness distribution and the composition of the pack ice is lacking.
