Local ice pressures for multiyear ice accounting for exposure
Cold Regions Science and Technology, 2010Abstract Local pressures are generally determined based on extreme pressures obtained in measurements. The exposure of structural components is an issue that needs attention. Exposure can be considered in everyday terms as “the longer you fish, the bigger the fish you catch.” In the case of design of offshore structures for ice environments, the more

Remote sensing of multiyear ice in the Antarctic
2021<p>The changing sea ice cover of polar seas is of key importance for the exchange of heat and moisture between atmosphere and ocean and hence for weather and climate, and in addition, the sea ice and its long-term changes are &#160;an indicator for global change.

Total and Methylated Mercury in Arctic Multiyear Sea Ice
Environmental Science & Technology, 2014Mercury is one of the primary contaminants of concern in the Arctic marine ecosystem. While considerable efforts have been directed toward understanding mercury cycling in the Arctic, little is known about mercury dynamics within Arctic multiyear sea ice, which is being rapidly replaced with first-year ice.

A thermal ice drill for profiling thick multiyear ice
Cold Regions Science and Technology, 1987Abstract An open-system hot water drill for arctic winter operation was developed to rapidly penetrate thickice features for the purpose of measuring ice thickness and for placing instrumentation into and beneath the ice. The thermal drill is composed of five modules, which can be quickly joined or disassembled.

Multiyear Arctic Sea Ice Classification Using OSCAT and QuikSCAT
IEEE Transactions on Geoscience and Remote Sensing, 2016Arctic sea ice can be classified as first-year (FY) or multiyear (MY) based on data collected by satellite microwave scatterometers. The Oceansat-2 Ku-band Scatterometer (OSCAT) was operational from 2009 to 2014 and is here used to classify ice as FY or MY during these years.

Improving Multiyear Ice Concentration Estimates With Reanalysis Air Temperatures
IEEE Transactions on Geoscience and Remote Sensing, 2016Multiyear ice (MYI) characteristics can be retrieved from passive or active microwave remote sensing observations. One of the algorithms that combine both observations to identify partial concentrations of ice types (including MYI) is the Environment Canada Ice Concentration Extractor (ECICE).

Arctic ice transformations: multiyear ice changes in comparison with summer minima
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003Passive satellite microwave data provide an extended time series for long-term monitoring of polar processes. Though the Arctic ice cover is composed of several types of ice, two major types of ice, which have explicitly different microwave emissivities, dominate in the region.
