The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick and over 3 km (1.9 mi) thick at its maximum. [ 2 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N , near ...

The Greenland Ice sheet Mapping Project (GrIMP) creates and provides benchmark data sets for observing Greenland ice sheet change and stability. The temporal range of data ranges from the year 1985 to present.

2024年12月25日 · The Greenland Ice Sheet is a single ice sheet or glacier covering about 80 percent of the island of Greenland. It is the largest ice mass in the Northern Hemisphere, globally second in size to only the Antarctic ice mass.

In addition to generating daily maps and graphs of surface melt data, Ice Sheets Today provides the following data tools with a focus on the Greenland Ice Sheet. Greenland Surface Melt Extent Interactive Chart. Explore the interactive graph below and look at …

2024年5月28日 · The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere. It lies from 71 ° N northwards, between the Atlantic and the Arctic Ocean [1]. Almost 80% of Greenland’s landmass is covered by the ice sheet, expanding an area over 1.7 million km 2 .

We summarize the mass changes for the 2024 mass balance year, 1 September 2023 through 31 August 2024, and discuss influential factors. The Greenland Ice Sheet gains mass chiefly from snow accumulation and loses mass through meltwater runoff and discharge of solid ice into the ocean (i.e., calving icebergs).

2015年1月26日 · A three-dimensional view of the age and structure of the Greenland Ice Sheet. Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first-ever comprehensive map of layers deep inside the Greenland Ice Sheet.
