Swimming paths of control (left) and copper (right) exposed fish
Swimming paths of control (left) and copper (right) exposed fishBehavioral Toxicology Laboratory — Columbia, Missouri. Swimming paths of control (left) and copper (right) exposed fish demonstrate changes in swimming behavior detected following exposure to metals. Such changes can impact ability of fish to survive.

fantail of the R/V Savannah
The fantail of the R/V Savannah loaded with USGS gear recovered from near Matanzas Inlet, FL. The data collected by the sensors in winter 2018 will be used to assess storm effects on coastal inlet dynamics.

lava lake within Halema‘uma‘u crater about 3 weeks before magma began
lava lake within Halema‘uma‘u crater about 3 weeks before magma beganThe active lava lake within Halema‘uma‘u crater about 3 weeks before magma began to withdraw from beneath the crater. Visible in the middle left of the photo behind the plume, is the old Overlook parking area, closed since 2008. The parking area slumped into the crater by June 21. View is toward the southwest.

Image of the Week - Landsat's View of the Boston Marathon
Image of the Week - Landsat's View of the Boston MarathonThis is a view of the route the Boston Marathon will take, as seen from Landsat 8.
At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.
