USGS scientist Margaret Lamont measures a Kemp’s ridley sea turtle recovered from the cold waters of St. Joseph Bay. Rescued sea turtles are weighed, measured andmarked with an identifier, and are examined to determine if they need medical attention. Photo by USGS.

When water temperatures drop below 50 degrees Fahrenheit (10 degrees Celsius), cold-blooded sea turtles, like this Kemp’s ridley, can become cold-stunned. They are unable to swim or even raise their heads out of the water to breathe, which can lead to drowning. Photo by Margaret Lamont, USGS

USGS scientists Daniel Catizone (left) and David Seay (center) joined federal and state workers and volunteers in rescuing an estimated 1,000 cold-stunned sea turtles, making this the second largest sea turtle rescue of the 21^st century. Photo by Margaret Lamont, USGS

Eglin Air Force Base biologist Kathy Gault (left) and Dave Seay (right), a contract biologist working with the USGS, hauled cold-stunned sea turtles to safety along the icy shore of Cape San Blas. Scientists and licensed volunteers walked the beaches and marshes, loading cold-stunned sea turtles into kayaks.

This image of the Ross Archipelago near the McMurdo Station in Antarctica was acquired January 1, 2018, by Landsat 8, almost exactly a decade after USGS and NASA officials signed off on a Landsat Data Distribution Policy that made Landsat images free to the public.

Eroding bluffs on Moss Landing State Beach, California, March 2016

Eroding permafrost on Alaska’s Arctic Coast. Inundation of permafrost like this produced subsea permafrost

Gas hydrate (white material) binding together coarse-grained sediments made up of pebble-sized rocks. This sample was recovered during a project to explore permafrost-associated gas hydrates in Canada’s Mackenzie Delta.

A large outbreak of gypsy moth (Lymantria dispar) caterpillars attacked the hardwood forests of the northeastern United States in 2016. A fungus (Entomophaga maimaigaM) introduced from Japan has kept gypsy moth populations at relatively low levels since the late 1980s.

Multichannel seismic-reflection profile across the Queen Charlotte-Fairweather fault, acquired aboard the R/V Norseman in August 2016. Dashed red line in enlarged section at lower right is the Queen Charlotte-Fairweather fault. m, meter; km, kilometer; ms, millisecond.

Orthomosaic images of Matanzas, Florida, from (a) before and (b) after Hurricane Matthew, and (c) a digital elevation model (DEM) showing the associated topographic change. Note, these results were produced by applying Structure-from-Motion (SfM) to NOAA oblique photographs, but similar results can be obtained using UAS aerial imagery.

Perspective views of multibeam bathymetry data acquired by the USGS aboard the R/V Medeia. Shallower depths in red. Arrows point to the distinct line in the seafloor associated with the Queen Charlotte-Fairweather fault.

Resurrection Bay on August 8, 2016. The water appeared calm in the shelter of the inner bay, but closer to the entrance, swells coming in from the Gulf of Alaska were breaking on a small beach where the three boaters had capsized.
