Geomorphically diverse settings that are experiencing climate-change impacts or are expected to in the coming decades (from upper left to lower right: eroding permafrost coast, river channel, drylands, cryosphere, steep hillslopes, and a recently burned region; photographs by U.S. Geological Survey).

An animation showing tectonic faults across the Eastern Pacific Ocean from space. The San Andreas fault in California is shown in green, and the Cascadia Subduction Zone north of it is shown in yellow. The animation ends at the location of Queen Charlotte-Fairweather fault (in yellow), displaying the latest 30-meter terrain model.

A computed-generated image showing the bathymetry of the Queen Charlotte Fault and the elevation of mountains in the nearshore area, using bathymetry and lidar data.

Our Nation’s coastlines are almost 100,000 miles long. These extensive coastal areas stretch from Maine’s Atlantic shores in the northeast, south along the shores of the Gulf of America and insular areas in the Caribbean.

A diagram that compares hand-digitization versus human-in-the-loop image segmentation workflows. The image (a) is the first in data set F, captured by Landsat 8 on 15 February 2015. The hand-drawn polygons (b) are rasterized to create a label image (c). Subplots (d) and (e) show details from the two regions identified in (c).
