Melt season in the Arctic Ocean has consistently experienced record lows in recent years. This year, a record low for the sea-ice extent (the area of ocean covered by the ice) was set in March, with relatively rapid ice loss continuing through May, according to NASA scientists. Although the melting slowed in June — likely keeping this year's summertime sea-ice minimum extent from setting a new record low — the Arctic ice is not bouncing back, the scientists said.
