Classifying the Ice Seasons 1982-2016 Using the Weighted Ice Days Number as a New Winter Severity Characteristic [PDF]
, 2017 Sea ice is a key climate factor and it restricts considerably the winter navigation in severe seasons on the Baltic Sea. So determining ice conditions severity and describing ice cover behavior at severe seasons are necessary.

Bohai Sea Ice Parameter Estimation Based on Thermodynamic Ice Model and Earth Observation Data
Remote Sensing, 2017 We estimate two essential sea ice parameters—namely, sea ice concentration (SIC) and sea ice thickness (SIT)—for the Bohai Sea using a combination of a thermodynamic sea ice model and Earth observation (EO) data from synthetic aperture radar (SAR) and ...

Assimilation of ice and water observations from SAR imagery to improve estimates of sea ice concentration [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2015 In this paper, the assimilation of binary observations calculated from synthetic aperture radar (SAR) images of sea ice is investigated. Ice and water observations are obtained from a set of SAR images by thresholding ice and water probabilities ...

Variability of the Northern Annular Mode's signature in winter sea ice concentration [PDF]
, 2003 Historical winter sea ice concentration data are used to examine the relation between the Northern Annular Mode (NAM) and the sea ice concentration in the Nordic seas over the past 50 years.

The Cryosphere, 2019 . We report on results of a systematic inter-comparison of 10 global sea-ice concentration (SIC) data products at 12.5 to 50.0 km grid resolution for both the Arctic and the Antarctic. The products are compared with each other with respect to differences

Version 2 of the EUMETSAT OSI SAF and ESA CCI sea-ice concentration climate data records
The Cryosphere, 2018 . We introduce the OSI-450, the SICCI-25km and the SICCI-50km climate data records of gridded global sea-ice concentration. These three records are derived from passive microwave satellite data and offer three distinct advantages compared to existing ...

Quantifying fusion born ion populations in magnetically confined plasmas using ion cyclotron emission [PDF]
, 2016 Ion cyclotron emission (ICE) offers unique promise as a diagnostic of the fusion born alpha-particle population in magnetically confined plasmas. Pioneering observations from JET and TFTR found that ICE intensity $P_{ICE}$ scales approximately linearly ...

The Migration Pattern of Atrazine during the Processes of Water Freezing and Thawing
Toxics, 2022 Atrazine, one of the most commonly used herbicides in the world, is of concern because of its frequent occurrence in various water bodies and the potential threat it constitutes to ecosystems. The transport of contaminants in seasonally ice-covered lakes

The impact of a seasonally ice free Arctic Ocean on the temperature, precipitation and surface mass balance of Svalbard [PDF]
, 2012 The observed decline in summer sea ice extent since the 1970s is predicted to continue until the Arctic Ocean is seasonally ice free during the 21st Century. This will lead to a much perturbed Arctic climate with large changes in ocean surface energy flux.
