Estimating summer ocean heating in the arctic ice pack using high-resolution satellite imagery
Recent observations have shown that the sea ice coverage and thickness in the Arctic Ocean is significantly decreasing. Areas of the Arctic that have traditionally been covered year-round with thick multiyear ice are being replaced by thinner first-year ice and open water. This results in increased...
