Anomalous collapses of Nares Strait ice arches leads to enhanced export of Arctic sea ice

open access: yesNature Communications, 2021
The ice arches that usually develop at the northern and southern ends of Nares Strait play an important role in modulating the export of Arctic Ocean multi-year sea ice.

Record low Antarctic sea ice coverage indicates a new sea ice state

open access: yesCommunications Earth & Environment, 2023
In February 2023, Antarctic sea ice set a record minimum; there have now been three record-breaking low sea ice summers in seven years. Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and ...

Regime shift in Arctic Ocean sea ice thickness

open access: yesNature, 2023
Manifestations of climate change are often shown as gradual changes in physical or biogeochemical properties^ 1 . Components of the climate system, however, can show stepwise shifts from one regime to another, as a nonlinear response of the system to a ...

Robust but weak winter atmospheric circulation response to future Arctic sea ice loss

open access: yesNature Communications, 2022
The possibility that Arctic sea ice loss weakens mid-latitude westerlies, promoting more severe cold winters, has sparked more than a decade of scientific debate, with apparent support from observations but inconclusive modelling evidence.

The Copernicus Global 1/12° Oceanic and Sea Ice GLORYS12 Reanalysis

open access: yesFrontiers in Earth Science, 2021
GLORYS12 is a global eddy-resolving physical ocean and sea ice reanalysis at 1/12° horizontal resolution covering the 1993-present altimetry period, designed and implemented in the framework of the Copernicus Marine Environment Monitoring Service (CMEMS).

Seasonal Arctic sea ice forecasting with probabilistic deep learning

open access: yesNature Communications, 2021
Anthropogenic warming has led to an unprecedented year-round reduction in Arctic sea ice extent. This has far-reaching consequences for indigenous and local communities, polar ecosystems, and global climate, motivating the need for accurate seasonal sea ...

INCORRECT MATCH DETECTION METHOD FOR ARCTIC SEA-ICE RECONSTRUCTION USING UAV IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Shapes and surface roughness, which are considered as key indicators in understanding Arctic sea-ice, can be measured from the digital surface model (DSM) of the target area.

Surface roughness signatures of summer arctic snow-covered sea ice in X-band dual-polarimetric SAR

open access: yesGIScience & Remote Sensing, 2020
Surface roughness of sea ice is primary information for understanding sea ice dynamics and air–ice–ocean interactions. Synthetic aperture radar (SAR) is a powerful tool for investigating sea ice surface roughness owing to the high sensitivity of its ...

Retrieval and parameterisation of sea-ice bulk density from airborne multi-sensor measurements [PDF]

open access: yesThe Cryosphere, 2022
Knowledge of sea-ice thickness and volume depends on freeboard observations from satellite altimeters and in turn on information of snow mass and sea-ice density required for the freeboard-to-thickness conversion.

Ice platelets below Weddell Sea landfast sea ice [PDF]

open access: yesAnnals of Glaciology, 2015
AbstractBasal melt of ice shelves may lead to an accumulation of disc-shaped ice platelets underneath nearby sea ice, to form a sub-ice platelet layer. Here we present the seasonal cycle of sea ice attached to the Ekström Ice Shelf, Antarctica, and the underlying platelet layer in 2012. Ice platelets emerged from the cavity and interacted with the fast-
