RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. Here, metal crosses create an above-ground microsite that can increase soil moisture by providing shade and collecting debris under some conditions.

RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. This photo shows the mulching treatment, which can increase soil moisture and lead to higher plant survival under some conditions.

USGS staff survey the Mill River near the former Hopewell Mills Dam site in Taunton, Massachusetts. Surveys at the dam-removal and culvert-retrofit sites provided topographic and bathymetric data for hydraulic models developed for the study.

A broken concrete foundation and some shattered floor tiles were all that remained of the sea turtle researchers' field station and home base after Category Four Hurricane Michael struck Cape San Blas on Oct. 10, 2018.

HVO staff visited the summit of Mauna Loa on foot to repair the webcam. The weather was perfectly clear, and views of the caldera floor showed nothing unusual.

Serapeum, a Roman Marketplace in Pozzuoli, Italy, records deformation of Campi Flegrei caldera over two millennia. It was built above sea level about 2000 years ago, but mollusk borings on the large marble columns indicate that it subsided by 7 meters (23 feet) below sea level before being uplifted above sea level once more in the past several hundred years.

The USGS collaborates with NASA, the University of Florida, National Park Service, and the U.S. Fish and Wildlife Service to assess coastal erosion hazards affecting space program infrastructure, habitat, and wildlife populations.
