Ponded ice

Webfor a portion of ponded ice of elementary area δa and thickness h, such pressure head is due to the hydrostatic pressure of the column of water in the pond overlying ice on δa, whose height is w,is(pin −pout) = ρwgδaw. The dischargeq equals the time variation of the overlying volume of water, V˙ = δaw˙, providing w˙ =−k ρwgw ηh, (11) WebDFS5.2 gives lower ponded ice area than JRA-55 Formation of sea ice →flattening of the ITD Topo. redistributes the melt water over the newly formed thin ice categories => shallow but extended melt ponds over the sea ice. The effect of the ponds on the total sea ice extent is restricted to summer months.

WebUnder-ice irradiance measurements were done on ponded first-year pack ice along three transects during the ICE12 expedition north of Svalbard. Webponded first-year pack ice along three transects during the ICE12 expedition north of Svalbard. Bulk transmittances (400–900nm) were found to be on average 0.15–0.20 under bare ice, and 0.39–0.46 under ponded ice. Radiative transfer modelling was done with a plane-parallel model.

WebOct 31, 2015 · In contrast, ponded ice absorbs or transmits to the ocean more than three-quarters of the incident sunlight. Characterization of the heat balance of a summertime ice cover is largely dictated by its pond coverage, and light transmittance through ponded ice shows strong contrast between first-year and multiyear Arctic ice covers. WebMay 11, 2024 · Abstract. Melt ponds on sea ice play an important role in the Arctic climate system. Their presence alters the partitioning of solar radiation: decreasing reflection, increasing absorption and transmission to the ice and ocean, and enhancing melt. The spatiotemporal properties of melt ponds thus modify ice albedo feedbacks and the mass …
