For the first time, high-resolution images show the three-dimensional structure of massive ice deposits on Mars. 

This high-resolution NASA HiRISE image shows a detailed subsection of an icy scarp on Mars in enhanced color.

This digital elevation model was created using structure from motion software mounted to an Unmanned Aerial System (UAS) to analyze bridge scour. Studies using UAS have included stream temperature analyses, bird and mammal surveys, coastal change mapping, sandbar habitat surveys, fluvial erosion rates, microclimate mapping, air quality analysis, plant stress as

Dry wash in San Rafael Desert with white surface salts. White efflorescent salts form on the soil surface as water evaporates from the soil leaving the salt at the surface. 

Rangelands of the desert Southwest can be in a degraded condition and lacking perennial vegetation, which can lead to exposed soil and erosion.

The CMHRP is testing the calcification rates of different genetic strains of threatened Elkhorn coral (Acropora palmata) to advise local and Federal agencies engaged in coral reef restoration.

Estimated and measured ocean depths (bathymetry) from Madeira Beach, Florida. Each panel shows same geographic area. m = meters. Left: Snapshot transformed from original oblique camera view to overhead “map” view. Middle: Bathymetry estimated by applying cBathy algorithm to July 2017 video imagery. Right: Bathymetry measured with sonar in February 2017.

Examples of sediment dynamics offshore of barrier islands include the development and erosion of shoals, tidal deltas, and sand ridges.

Fish Creek wanders through the National Petroleum Reserve-Alaska, a 22.8 million acre region managed by the Bureau of Land Management on Alaska's North Slope. USGS has periodically assessed oil and gas resource potential there. These assessments can be found here.

Gila monsters are one of only two venomous lizard species in the world. They live in the southwestern U.S. and in Mexico. This animated GIF comes from a video that short features USGS Emeritus Research Ecologist, Cecil Schwalbe describing details of Gila monster biology and ecology and how he survived a very painful Gila monster bite.
