Sea Ice Concentration and Sea Ice Extent Mapping with the Fsscat Mission: A Neural Network Approach
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Knowledge about sea ice concentration and extent in polar regions is of great interest both for economic interests, and as a proxy of the climate change. Retrieved maps are based on data from microwave radiometers, which are currently provided by large satellite missions. Nowadays, CubeSats have proven to be a cost-effective alternative.

Sea salt as an ice core proxy for past sea ice extent: A process‐based model study [PDF]
Journal of Geophysical Research D: Atmospheres, 2014 AbstractSea ice is a reflection of, and a feedback on, the Earth's climate. We explore here, using a global atmospheric chemistry‐transport model, the use of sea salt in Antarctic ice cores to obtain continuous long‐term, regionally integrated records of past sea ice extent, synchronous with ice core records of climate.

Global Warming and Northern Hemisphere Sea Ice Extent
Science, 1999Surface and satellite-based observations show a decrease in Northern Hemisphere sea ice extent during the past 46 years. A comparison of these trends to control and transient integrations (forced by observed greenhouse gases and tropospheric sulfate aerosols) from the Geophysical Fluid Dynamics Laboratory and Hadley Centre climate models reveals that ...

Arctic sea ice extent and thickness
Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1995Abstract Current knowledge on Arctic sea ice extent and thickness variability is reviewed, and we examine whether measurements to date provide evidence for the impact of climate change. The total Arctic ice extent has shown a small but significant reduction of (2.1 ± 0.9)% during the period 1978-87, after apparently increasing from a ...

SMOS Sea Ice Thickness Data Product Quality Control by Comparison with the Regional Sea Ice Extent
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Brightness temperature data from wave Imaging Radiometer using Aperture Synthesis (MIRAS) on board the European Space Agency's (ESA) Soil Moisture and Ocean Salinity (SMOS) mission have been used to derive the thickness of thin sea ice for the Arctic freeze-up period.

Regional variability of Antarctic sea ice extent
Russian Meteorology and Hydrology, 2016Interannual and seasonal variability of regional distribution of Antarctic sea ice extent is studied using monthly mean data on sea ice concentration in 1970-2012. The correlation is estimated between the variations in the area of floating ice in West and East Antarctica as well as in the Atlantic, Pacific, and Indian sectors of the Southern Ocean and ...

Expected Arctic Sea Ice extent as on 2036
2016 International Conference on Recent Advances and Innovations in Engineering (ICRAIE), 2016This paper is an extension to the paper entitled “Arctic Sea Ice Variability and Trend over Past Two Decade” presented in National Symposium on Weather & Climate Extremes, Chandigarh [1]. There the arctic sea ice variability was studied from 1990 to 2012 only.

Ice extent in the Greenland Sea 1978–1995
Deep Sea Research Part II: Topical Studies in Oceanography, 1999Abstract During the European Subpolar Ocean Programme (ESOP) project from 1993 to 1995, very little ice was formed in the central Greenland Sea. The large-scale ice cover in the area during the period October 1978 to June 1995 has been mapped using passive microwave data from the scanning multichannel microwave radiometer (SMMR) and the special ...

Antarctic Sea Ice Extent Variability and Its Global Connectivity*
Journal of Climate, 2000Abstract This study statistically evaluates the relationship between Antarctic sea ice extent and global climate variability. Temporal cross correlations between detrended Antarctic sea ice edge (SIE) anomaly and various climate indices are calculated. For the sea surface temperature (SST) in the eastern equatorial Pacific and tropical Indian Ocean, as

The antarctic winter; simulations with climatological and reduced sea‐ice extents
Quarterly Journal of the Royal Meteorological Society, 1989AbstractThe southern hemisphere climatology of a recent version of the Meteorological Office 11‐layer general circulation model is presented. The simulated climate is compared with observational data, including Meteorological Office operational analyses for the period 1983‐1987.
