The Arctic sea ice is characterised by means of profound alterations brought on by floor melting techniques and the formation of soften ponds in summer time. soften ponds give a contribution to the ice-albedo suggestions as they decrease the outside albedo of sea ice, and for this reason speed up the decay of Arctic sea ice. To quantify the melting of the full Arctic sea ice, satellite tv for pc dependent observations are important. as a result of diversified spectral houses of snow, ice, and water, theoretically, multi-spectral optical sensors are important for the research of those detailed floor forms. This research demonstrates the opportunity of optical sensors to become aware of soften ponds on Arctic sea ice. For the 1st time, an Arctic-wide, multi-annual soften pond facts set for the years 2000-2011 has been created and analyzed.
