Ice production and salt rejection of Laptev Sea polynyas,using model and remote sensing data
The Laptev Sea polynyas in the Siberian Arctic are well recognized as strong ice producers [1, 2] and may play a critical role with regards to sea ice volume changes in the Arctic. These flaw polynyas were studied during two seasonal cycles (2007 – 2009) by the Russian-German research project “Laptev Sea System” [3]. A focus was set on an investigation of the contribution of the West New Siberi...
متن کاملMultisensor data and thermodynamic sea-ice model based sea-ice thickness chart with application to the Kara Sea, Arctic Russia
We introduce a method to construct an ice thickness chart using two satellite datasets and a one-dimensional high-resolution thermodynamic snow and sea-ice model (HIGHTSI). Thin-ice thickness up to 40 cm is retrieved using MODIS ice surface temperature data. For thicker ice, thickness is retrieved from a combination of SAR image and background level ice thickness chart Hi provided by HIGHTSI. B...
متن کاملBohai Sea Ice Parameter Estimation Based on Thermodynamic Ice Model and Earth Observation Data
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 microwave radiometer. We compare the SIC and SIT estimation results with in-situ measurements conducted in the study area and estimates based on ...
متن کاملSea ice production and export from coastal polynyas in the Weddell and Ross Seas
[1] For 1992–2008, we use data from the Special Sensor Microwave/Imager (SSM/I) and the Advanced Microwave Scanning Radiometer‐EOS (AMSR‐E) to examine differences in ice production and export in the Weddell and Ross Seas. We find that the Ross production is three times that in the Weddell; the Ross export, twice that in the Weddell. In the Ross, the ice production has a statistically significan...
متن کامل3a.7 Parallel Climate Model Simulations with a Dynamic-thermodynamic Ice Thickness Distribution Model
Global climate model simulations are influenced by the explicit or parameterized physical processes that they include. Most climate models have some representation of sea ice in the polar regions, which contributes to ice-albedo feedback and a dramatic increase in climate change in the polar regions. Some sea ice components of coupled climate models have been improved in recent years to include...
