At least 300 active volcanoes dot the Kamchatka Peninsula, which lies along the geologically active Pacific Ring of Fire. Landsat 8 caught this plume of ash and smoke streaming from one of these volcanoes - Klyuchevskaya - on January 10, 2018.

Measuring streamflow, Yellowstone River at Lake Outlet

On January 8, 2018, Kīlauea Volcano's summit lava lake level was 38 m (125 ft) below the rim of "Overlook crater," the small crater that formed above the active vent in Halema‘uma‘u.

 During wintry conditions, streamflow is often measured under ice. This often means using an ice auger to cut holes through the ice, at increments across the full width of the stream.

USGS hydrologic technicians Kevin Baker (shown in the picture) and Jarvis Kaderlik found the Souris River near Westhope, ND (streamgage 05124000) to be at zero flow on January 4, 2018.

First high-definition thermal image of the Halema‘uma‘u lava lake in the New Year, taken shortly after midnight on January 1, 2018. This camera was deployed to track the dynamic surface activity of the lava lake at the summit of Kīlauea.

A massive iceberg broke off Pine Island Glacier, Antarctica, in September 2017. Instead of drifting out to sea after calving, sea ice impeded the iceberg’s movement, and it cracked up into countless pieces nearly on the spot. Even though it broke up relatively quickly for an iceberg, it is more of a slow-motion shattering.

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

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.
