Rising Seas -- Ultra High Definition Images from Greenland and Beyond

With an array of approaches including boots on the ground, aerial surveys, ship-board missions, model outputs, and the satellite view from space, NASA science makes major contributions to the study of sea level rise. This gallery contains both data visualizations and new 4K footage shot in Greenland in July, 2015.

  • 22-year Sea Level Rise

    23 year Sea Level Rise. Earth spins once before camera zooms into West Atlantic, East Pacific, and West Pacific regions
  • NASA GSFC MASCON Solution over Greenland from Jan 2004 - Jun 2014

    GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth's gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the mass of the Earth's ice sheets. This animations shows the change in the the Greenland Ice Sheet between January 2004 and June 2014. The 1-arc-deg NASA GSFC mascon solution data was resampled to a 998 x 1800 data array using Kriging interpolation. A color scale was applied in the range of +250 to -250 centimeters of equivalent water height, where blue values indicate an increase in the ice sheet mass while red shades indicate a decrease. In addition, the running sum total of the accumulated mass change over the Greenland Ice Sheet is shown on a graph overlay in gigatons.

    GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth's gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the mass of the Earth's ice sheets. This animations shows the change in the mass of the Antarctic Ice Sheet between January 2004 and June 2014 as measured by the pair of GRACE satellites. The 1-arc-deg NASA GSFC mascon solution data was resampled to a 5130 x 5130 data array using Kriging interpolation. A color scale was applied in the range of +250 to -250 centimeters of equivalent water height, where blue values indicate an increase in the ice sheet mass while red shades indicate a decrease. In addition, a graph overlay shows the running total of the accumulated mass change in gigatons. The data is first shown over the entire Antarctic Ice Sheet with the graph showing the total change in gigatons for the full ice sheet. The camera then zooms to focus on the West Antarctic Ice Sheet where much of the loss has taken place. The animation is shown again over this region while the graph of ice loss presents the change over West Antarctica alone. Regions composed of the floating ice shelves and thus not a part of the Antarctic Ice Sheet are shown in a pale shade of green.
  • Measuring Elevation Changes on the Greenland Ice Sheet

    This narrated animation shows the accumulated change in the elevation of the Greenland ice sheet between 2003 and 2012. This is the official release without the scrolling credits.

  • Greenland's Glaciers as seen by RadarSat
    2015.08.25
    An animation up the Greenland's Sermilik Fjord to the claving front of the Helheim Glacier, showing the change over time of the glacier front from 2000 to 2013.
  • Greenland Ice Sheet stratigraphy
    2015.01.23
    For nearly a century, scientists have been studying the form and flow of the Greenland Ice Sheet. They have measured the change in the elevation of the surface over time using satellites. They have drilled ice cores in the field to reveal a record of what the past climate was like. They have flown aircraft over the surface of the ice sheet laden with instruments to gleen information about the interior of the ice sheet and the bedrock below. Now a new analysis of this data has revealed a three dimensional map of the age of the ice sheet. This animation shows this new 3D age map of the Greenland Ice Sheet, explains how it was created and describes the three distinct periods of climate that are evident within the ice sheet. The full script of the narration is available here. More information is available here.
