A scientist takes a gravity reading at a station located on the down-dropped block of Kīlauea caldera, which subsided as an intact structure, while a second gravity instrument (foreground) records data. Many of the preexisting gravity stations, which have been measured for years, survived Kīlauea's 2018 summit collapse.

U.S. Geological Survey (USGS) scientist working on data analysis of cyanotoxins in water samples

A USGS scientist prepares a sample to test the effect of antibiotics on denitrifying bacteria within a glove box. A glove box allows scientists to work with samples in an anaerobic (no oxygen) atmosphere, the conditions under which denitrification occurs.
