            "description": "On Enceladus under a crust of ice lies a global ocean of salty water. Jets, supplied by that ocean, gush from the surface of the moon and feed into the entire system of Saturn. NASA’s James Webb Space Telescope first look at this ocean world is revealing that a plume spouts water out more than 20 times the size of the moon itself. Enceladus, together with its sub-surface ocean, is one of the most exciting scientific targets in our solar system in the search for life beyond Earth. Sandwiched between the moon’s icy outer crust and its rocky core is a global reservoir of salty water. Geyser-like volcanos spew jets of ice particles, water vapor, and organic chemicals out of crevices in the moon’s surface informally called ‘tiger stripes.’ In this video, we show a possible scenario of how water could be being sourced from hydrothermal vents in the sub-surface ocean to generate the observed plumes. || ",

            "description": "Our understanding of what lies beneath the world's biggest ice sheet has taken another leap forward. Thanks to work led by the British Antarctic Survey, scientists have a new 3D map of Antarctica’s ice and bedrock. The map, called Bedmap2, incorporates millions of new measurements, including data collected by NASA's ICESat satellite and airborne Operation IceBridge mission. The result is a virtual reconstruction of the continent’s bedrock topography and ice layers captured in never-before-seen detail. Antarctica plays a large role in the global climate system. The melting and emptying of its ice into the sea influences ocean currents and the rate of sea level rise. By having a precise map of Antarctica’s mountains, ridges, slopes and valleys—all of which affect how fast the continent's ice travels across the ice sheet—scientists can better predict future rates of ice flow.

            "description": "In certain parts of Antarctica, the ice is disappearing—fast. To better understand how and why this is happening, NASA's Operation IceBridge mission uses a suite of advanced instruments aboard its DC-8 aircraft to survey the continent's layered ice deposits and underlying bedrock. One place scientists are looking at closely is the Getz Ice Shelf. The underside of this 300-mile-long floating tongue of ice hanging off West Antarctica is being eaten away by warm ocean currents. And a thin crack on its surface threatens to calve a large piece of it into the sea. In 2012, researchers mapped regions near the ice shelf's grounding line, the point where the ice leaves the support of land and begins to float on water, to determine how much ice is being lost to the ocean, and at what rate.

            "description": "Using five years of data from NASA's Ice, Cloud and land Elevation Satellite (ICESat), a team of NASA and university scientists made the first basin-wide estimate of the thickness and volume of the Arctic Ocean ice cover between 2003 and 2008. The scientists found that younger, thinner ice has replaced older, thicker ice as the dominant type over the past five years. Until recently, the majority of Arctic ice survived at least one summer and often several. That balance has now flipped. Seasonal ice, or ice that melts and re-freezes every year, now comprises about 70 percent of the Arctic sea ice in wintertime, up from 40 to 50 percent in the 1980s and 1990s. Thicker ice - surviving two or more years - now comprises just 10 percent of ice cover, down from 30 to 40 percent in years past.Sea ice thickness has been hard to measure directly so scientists have typically used estimates of ice age to approximate thickness. With ICESat, NASA scientists were for the first time able to monitor the ice thickness and volume changes over the entire Arctic Ocean. The Arctic ice cap grows each winter as the sun sets for several months and intense cold sets in. The total volume of winter Arctic ice is equal to the volume of fresh water in Lake Superior and Lake Michigan combined. Some of that ice is naturally pushed out of the Arctic by winds, while much of it melts in place. But not all of the ice in the Arctic melts each summer, and the thicker, older ice that survives one or more summers is more likely to persist through the next summer. This older, thicker ice is declining thinner ice that is more vulnerable to summer melt. Seasonal sea ice usually reaches about 2 meters (6 feet) in thickness, while ice that has lasted through more than one summer averages 3 meters (9 feet), though it can grow much thicker in some locations near the coast. From 2003 to 2008, multi-year ice has thinned by an average of 60 centimeters (2 feet). The total ice volume in winter has decreased by 6,300 cubic kilometers, or 40 percent. The maximum extent of multi-year ice is now one-third of what it was in the 1990s. || ",
