The Arctic is melting faster than we thought it would. In fact, Arctic ice extent is at a record low. When that happens—when a natural system behaves differently than scientists expect—it's time to take another look at ...

When spring arrives in the Arctic, both snow and sea ice melt, forming melt ponds on the surface of the sea ice. Every year, as global warming increases, there are more and larger melt ponds.

In 2011, researchers observed something that should be impossible—a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. ...

When spring comes to the Arctic, the breakup of the cold winter ice sheets starts at the surface with the formation of melt ponds. These pools of melted snow and ice darken the surface of the ice, increasing the amount of ...

Two key climate change indicators—global surface temperatures and Arctic sea ice extent—have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite ...

This summer, with sea ice across the Arctic Ocean shrinking to below-average levels, a NASA airborne survey of polar ice just completed its first flights. Its target: aquamarine pools of melt water on the ice surface that ...

Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal clear pools.

Sea ice in summer looks dramatically different than sea ice in winter, even in the polar Arctic. Summer snowmelt, pools of water on thinning ice and exposed ocean replace vast winter expanses of white snow-covered ice – ...
