WebTransmittances through the ponded ice were roughly an order of magnitude larger than the bare ice . The peak transmittance was 0.46 at 425 nm for ponded ice and 0.034 at 520 nm for bare ice. In both bare and ponded ice cases, transmittances decreased sharply beyond 700 nm owing to increased absorption by the ice.

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. While sim-ulated transmittances deviate significantly ... 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.
