From Bright Windows to Dark Spots: Snow Cover Controls Melt Pond Optical Properties During Refreezing
Melt ponds have a strong impact on the Arctic surface energy balance and the ice-associated ecosystem because they transmit more solar radiation compared to bare ice. In the existing literature, melt ponds are considered as bright windows to the ocean, even during freeze-up in autumn. In the central...
