Sea ice transports in the Weddell Sea [PDF]
Journal of Geophysical Research: Oceans, 2001 Time series of sea ice draft in the Weddell Sea are evaluated together with hydrographic observations, satellite passive microwave data, and ice drift for estimation of the freshwater fluxes into and out of the Weddell Sea. Ice draft is measured with moored upward looking sonars since 1990 along two transects across the Weddell Gyre.

Assimilation of sea ice motion in a finite‐element sea ice model [PDF]
Journal of Geophysical Research: Oceans, 2009 A finite‐element sea ice model (FESIM) is applied in a data assimilation study with the singular evolutive interpolated Kalman (SEIK) filter. The model has been configured for a regional Arctic domain and is forced with a combination of daily NCEP reanalysis data for 2‐m air temperature and 10‐m winds with monthly mean humidities from the ECMWF ...

Improving Multiyear Sea Ice Concentration Estimates with Sea Ice Drift [PDF]
Remote Sensing, 2016 Multiyear ice (MYI) concentration can be retrieved from passive or active microwave remote sensing observations. One of the algorithms that combines both observations is the Environmental Canada Ice Concentration Extractor (ECICE). However, factors such as ridging, snow wetness and metamorphism can cause significant changes in brightness temperature ...

, 2020 1) The annual cycle of atmospheric methane in southern high latitudes is extremely highly correlated with Antarctic sea ice extent. 2) The annual cycle of atmospheric methane in the Arctic is highly correlated with Antarctic or Arctic plus Antarctic sea ice extent.

In Situ Experimental Study of the Friction of Sea Ice and Steel on Sea Ice [PDF]
Applied Sciences, 2018 The kinetic coefficient of friction μk was measured for sea ice, stainless steel, and coated steel sliding on a natural sea ice cover. The effects of normal stress (3.10–8.11 kPa), ice columnar grain orientation (vertical and parallel to the sliding direction), sliding velocity (0.02–2.97 m·s–1), and contact material were investigated.

Sea ice phenology in the Caspian Sea
Advances in Oceanography and Limnology, 2021 To understand the spatial and temporal variations in the extent and timing of sea ice in the Caspian Sea (CS), 15 years of sea ice presence and its phenology (freeze-up, break-up, and duration) were studied in the Northern CS (NCS) for a period from 2004 to 2018.

The northern sector of the last British ice sheet : maximum extent and demise [PDF]
, 2008 Strongly divided opinion has led to competing, apparently contradictory, views on the timing, extent, flow configuration and decay mechanism of the last British Ice Sheet.

Prediction of monthly Arctic sea ice concentrations using satellite and reanalysis data based on convolutional neural networks [PDF]
, 2020 Changes in Arctic sea ice affect atmospheric circulation, ocean current, and polar ecosystems. There have been unprecedented decreases in the amount of Arctic sea ice due to global warming.

, 2022 Abstract 1) Atmospheric oxygen cycles on a seasonal basis, as does carbon dioxide. 2) Photosynthesis is likely contributing to these cycles, but the dominant spatial regions are unknown and the contribution of marine plankton has been assumed to be small. 3) I test and confirm the prediction that seasonal sea ice and oxygen rates are highly

Sea ice is a mushy layer [PDF]
Geophysical Research Letters, 2006 Sea ice is a two‐phase, two‐component, reactive porous medium: an example of what is known in other contexts as a mushy layer. The fundamental conservation laws underlying the mathematical description of mushy layers provide a robust foundation for the prediction of sea‐ice evolution.
