PROCEDURE OF EXTRACTING THIN ICE AREAS IN THE SEA OF OKHOTSK USING MODIS DATA [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
The latest IPCC report clearly stated that the human influence is the main reason of sea ice reduction in the Arctic. Importance of sea ice monitoring from space is increasing.

Grease-ice thickness parameterization [PDF]

open access: yesAnnals of Glaciology, 2011
AbstractGrease ice is a mixture of sea water and frazil ice crystals forming in Arctic and Antarctic waters. the initial grease-ice cover, or the grease ice forming during winter in leads and polynyas, may therefore have mixed properties of water and ice.

Airborne electromagnetic sea ice thickness sounding in shallow, brackish water environments of the Caspian and Baltic Seas [PDF]

open access: yes, 2006
Ice engineering projects often rely on the knowledge of ice thickness in shallow, brackish water like in the Baltic and Caspian Seas. By means of field data and model results, the paper shows that helicopter-borne electromagnetic induction measurements ...

Antarctic ice sheet thickness estimation using the horizontal-to-vertical spectral ratio method with single-station seismic ambient noise [PDF]

open access: yesThe Cryosphere, 2018
We report on a successful application of the horizontal-to-vertical spectral ratio (H / V) method, generally used to investigate the subsurface velocity structures of the shallow crust, to estimate the Antarctic ice sheet thickness for the first time.

Measuring and inferring the ice thickness distribution of four glaciers in the Tien Shan, Kyrgyzstan

open access: yesJournal of Glaciology, 2021
Glaciers in the Tien Shan mountains contribute considerably to the fresh water used for irrigation, households and energy supply in the dry lowland areas of Kyrgyzstan and its neighbouring countries. To date, reconstructions of the current ice volume and

Arctic sea ice thickness, volume, and multiyear ice coverage: losses and coupled variability (1958–2018)

open access: yesEnvironmental Research Letters, 2018
Large-scale changes in Arctic sea ice thickness, volume and multiyear sea ice (MYI) coverage with available measurements from submarine sonars, satellite altimeters (ICESat and CryoSat-2), and satellite scatterometers are summarized. The submarine record

Estimating ice discharge of the Antarctic Peninsula using different ice-thickness datasets

open access: yesAnnals of Glaciology, 2023
The Antarctic Peninsula Ice Sheet (APIS) has become a significant contributor to sea-level rise over recent decades. Accurately estimating the ice discharge from the outlet glaciers of the APIS is crucial to quantify the mass balance of the Antarctic ...

Ice thickness, volume and subglacial relief of Djankuat Glacier (Central Caucasus)

open access: yesЛëд и снег, 2015
In this paper we present and discuss results of radio-echo sounding and modelling of ice thickness of the Djankuat Glacier. This glacier is the reference one for the Central Caucasus and was earlier studied comprehensively, but direct ice thickness ...

Impact of assimilating sea ice concentration, sea ice thickness and snow depth in a coupled ocean–sea ice modelling system

open access: yesThe Cryosphere, 2019
. The accuracy of the initial state is very important for the quality of a forecast, and data assimilation is crucial for obtaining the best-possible initial state.

Enhancing sea ice knowledge through assimilation of sea ice thickness from ENVISAT and CS2SMOS [PDF]

open access: yesThe Cryosphere
Arctic sea ice extent has declined significantly over the past four decades, opening up the Arctic to shipping and resource extraction while also impacting wildlife and local communities.
