Sea Ice Melt Ponds: Snow, SSL, and Pond Depths


Snow, surface scattering layer (SSL), or melt pond depths are measured by inserting a metal probe with centimeter gradations into the surface until it struck hard ice. Positive (+) measurements reflect snow or loose decaying ice crystals known as the surface scattering layer, while negative (-) measurements indicate melt pond depths. Measurements were made every 0.5m, along the transect lines.
