The influence of sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms in the Chukchi Sea
A coupled biophysical model is used to examine the impact of changes in sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms (MUPBs) in the Chukchi Sea of the Arctic Ocean over the period 1988–2013. The model is able to reproduce the basic features of the ICESCAPE (Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environ...
متن کاملNutrient status of snow cover and sea ice in the southern Sea of Okhotsk
Samples of sea ice and snow cover on sea ice were collected with the icebreaker P/V Soya in early February 2007 in the southern Sea of Okhotsk in order to evaluate the amount of nutrients in the sea ice and snow. The concentration of nitrate + nitrite, phosphate and silicic acid in the samples was measured in conjunction with such physical parameters as temperature, salinity, oxygen isotopic ra...
متن کاملKu-band radar penetration into snow cover on Arctic sea ice using airborne data
Satellite radar altimetry provides data to monitor winter Arctic sea-ice thickness variability on interannual, basin-wide scales. When using this technique an assumption is made that the peak of the radar return originates from the snow/ice interface. This has been shown to be true in the laboratory for cold, dry snow as is the case on Arctic sea ice during winter. However, this assumption has ...
متن کاملActual and insolation - weighted Northern Hemisphere snow cover and sea - ice between 1973 – 2002
Actual and insolation-weighted Northern Hemisphere snow cover and sea ice are binned by latitude bands for the years 1973–2002. Antarctic sea-ice is also analyzed for the years 1980–2002. The use of insolation weighting provides an improved estimate of the radiative feedbacks of snow cover and sea-ice into the atmosphere. One conclusion of our assessment is that while a decrease in both areal a...
متن کاملSnow on Antarctic Sea Ice
Snow on Antarctic sea ice plays a complex and highly variable role in air-sea-ice interaction processes and the Earth’s climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics: snow thickness and snow type and their geographical and seasonal variations; snow grain size, density, and salinity; frequency of occurrence of slush; thermal conduct...
