• Greenland - East View Geospatial

    Geological mapping began in western Greenland, but extended to eastern Greenland in the late 1960s and later to North Greenland in cooperation with the KMS orthophotomapping project. The basic series are restricted to the ice-free coastal zone and comprise a series of 1:100,000 scale sheets, and a more extensive series of bedrock and quaternary sheets, mostly at 1:500,000 scale.

  • Geographic information system - Wikipedia

    A geographic information system (GIS) is a conceptualized framework that provides the ability to capture and analyze spatial and geographic data. GIS applications (or GIS apps) are computer-based tools that allow the user to create interactive queries (user-created searches), store and edit spatial and non-spatial data, analyze spatial information output, and visually share the results of these operations by presenting them as maps.

  • Greenland Ice Sheet Today | Surface Melt Data presented by NSIDC

    Overview of ConditionsConditions in ContextAcknowledgementsSurface melting on the Greenland ice sheet ramped down at a near-normal pace in the weeks following the major melt event of early August (Figure 1). Only a few minor late-season melt events occurred in September and October. Overall, melting on the Greenland ice sheet for 2019 was the seventh-highest since 1978, behind 2012, 2010, 2016, 2002, 2007, and 2011 (Figure 2). Since 2000, the ice sheet has experienced a general increase in melting, with melt-day area for 2019 totaling 28.3 million square kilometers (10.9 million square miles) for the season. Melting was observed over nearly 90 percent of the island on at least one day, reaching the Summit Station and much of the high-altitude areas. It was particularly intense along the northern edge of the ice sheet, where compared to the 1981 to 2010 average, melting occurred for an additional 35 days. The number of days with melting was slightly above average along the western flank of the ice sheet as well, with about 15 to 20 more days...
