Empirical sea ice thickness retrieval during the freeze-up period from SMOS high incident angle observations [PDF]

The Cryosphere, 2014
Sea ice thickness information is important for sea ice modelling and ship operations. Here a method to detect the thickness of sea ice up to 50 cm during the freeze-up season based on high incidence angle observations of the Soil Moisture and ...

Sea ice dynamics across the Mid-Pleistocene transition in the Bering Sea

Nature Communications, 2018
Modelling studies propose sea ice to be one of the underlying mechanisms for the Mid-Pleistocene transition. Here, the authors show Mid-Pleistocene subarctic North Pacific sea ice dynamics based on biomarkers and biogenic opal accumulation rates ...

Effect of compressive loading on first-year sea-ice permeability

Journal of Glaciology, 2018
The permeability of sea ice can strongly affect the dissipation of wave energy into the ice pack. Sea-ice permeability is known to be impacted by the brine volume fraction and the blockage of flow pathways by the freezing of infiltrating lower salinity ...

Sub-kilometre scale distribution of snow depth on Arctic sea ice from Soviet drifting stations

Journal of Glaciology, 2022
The sub-kilometre scale distribution of snow depth on Arctic sea ice impacts atmosphere-ice fluxes of energy and mass, and is of importance for satellite estimates of sea-ice thickness from both radar and lidar altimeters.

The gravitationally consistent sea-level fingerprint of future terrestrial ice loss [PDF]

, 2013
We solve the sea-level equation to investigate the pattern of the gravitationally self-consistent sea-level variations (fingerprints) corresponding to modeled scenarios of future terrestrial ice melt.

New insight from CryoSat-2 sea ice thickness for sea ice modelling [PDF]

The Cryosphere, 2019
Estimates of Arctic sea ice thickness have been available from the CryoSat-2 (CS2) radar altimetry mission during ice growth seasons since 2010. We derive the sub-grid-scale ice thickness distribution (ITD) with respect to five ice thickness categories ...

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]

, 2014
Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics [PDF]

, 2015
Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream (IIS) catchment.

Towards an improved organic carbon budget for the western Barents Sea shelf [PDF]

Climate of the Past, 2014
There is generally a lack of knowledge on how marine organic carbon accumulation is linked to vertical export and primary productivity patterns in the Arctic Ocean.

Towards improving short-term sea ice predictability using deformation observations [PDF]

The Cryosphere, 2023
Short-term sea ice predictability is challenging despite recent advancements in sea ice modelling and new observations of sea ice deformation that capture small-scale features (open leads and ridges) at the kilometre scale.
