USGS scientists install a thermal imaging system in the National Park of American Samoa off the south shore of Ofu, Manua. The system detects temperature variations, like a colder freshwater plume that emanates from the shore.

The sampling mechanism (on blue tarp) is prepared and the Unoccupied Aircraft System (UAS) is inspected just before take off to collect water from the Halema‘uma‘u crater lake. Brightly colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water.

The tidal gage is located at the confluence of Coyote Creek and Alviso Slough, and is accessible only by boat. The estuary is fed by the Sacramento and San Joaquin Rivers, and various tributaries in the Central Valley.

USGS researchers Chris Moore and Mitchell Lemon took a trip on the R/V Weatherbird in January of 2020 with the University of South Florida College of Marine Science as part of a study on carbon dioxide in the Gulf of Mexico. Carbon Dioxide, or CO2, is a greenhouse gas that can be absorbed by the ocean.

El Servicio Geológico de los EE. UU. ha publicado un informe sobre la duración potencial de las réplicas de la secuencia (serie) del terremoto del Suroeste de Puerto Rico en el 2020 que puede ser usado como guía en las decisiones de política pública, otras acciones y ayudar a las personas a mantenerse seguras y cuidarse a sí mismas y a los demás.

This core sample was taken from an elkhorn coral reef offshore of the Fort Lauderdale region of Florida. Samples from coral skeletons are taken from numerous locations in the core for radiocarbon dating, which tells scientists the age of each coral and of sections within the reef. The corals in this core lived from 7,100 to 6,200 years ago.

This piece of a core sample taken from offshore of the Fort Lauderdale region of Florida is from an elkhorn coral that lived 6,200 years ago. Coral type, orientation of corallites, and evidence of other fauna and characteristics within the core sample are used to determine how reliable the coral sample is to use for past sea-level reconstruction.
