MARC recordFormation of turbid ice during autumn freeze-up in the Kara Sea / Lars H. Smedsrud.
| Title: | Formation of turbid ice during autumn freeze-up in the Kara Sea / Lars H. Smedsrud. |

| Abstract: | Estimates mass of ice-rafted sediment in turbid sea ice on Kara Sea. Presents one-dimensional vertical model of sediment entrainment by aggregation with frazil ice crystals that are diffused downward by wind-generated turbulence during autumn freeze-up. Selects six areas of Kara shelf (depths <100 m) and typical vertical stratifications (salinity profiles) based on CTD data. Discusses model initialisation with river inflow and sediment processes, and wind, snow and air temperature data from local meteorological stations used as forcing for frazil and sediment model. Finds freeze-up has capacity to incorporate total summer sediment discharge into surface ice. Presents tests of sensitivity to forcing, discusses model limitations, and compares results with available field data. |
