ICESat-2 Maps Subglacial Lakes in Antarctica
July 29, 2021, 3 p.m.
Read moreData visualization featuring precise map of Mercer and Conway subglacial lakes in West Antarctica. The visualization sequence starts with a view of the Americas and slowly zooms into the suture between the Mercer and Whillans ice streams. Surface-height anomaly data from NASA s ICESat-2 mission for Conway and Mercer subglacial lakes. This sequence includes colorbar, timestamp, scale bar information. This set of frames provides the subglacial lakes data overlay geo-registered on top of the New Landsat Image Mosaic of Antarctica (LIMA). Frames are provided in 4K and HD resolution. This set of frames provides the data layer of the subglacial lakes visualization sequence. Frames are provided with transparency in 4K and HD resolutions. Outlines of Lake Conway (left) and Lake Mercer (right). This still image is provided with transparency. Scale bar provided in 4K and HD resolutions. This set of frames provides the timestamp overlay of the subglacial lakes data visualization sequence. Frames are provided with transparency in 4K rersolution. Still image of colorbar layer for the subglacial lakes data visualization sequence. The still image is provided with transparency in 4K resolution. Colorbar (with annotations) of subglacial lake surface-height anomalies. Colorbar created for the subglacial lakes data. Brown-white-blue divergent colorbar to separate the subglacial lake height anomalies above (orange/low to brown/high) and below (light blue/shallow to dark blue/deep) surface. The colorbar is applied to the study area of Lake Conway and Lake Mercer.
