Recent Coastal and Marine Fieldwork - April-May 2019
In May 2019, USGS coastal and marine scientists visited several coastal and offshore locations, studying reservoir sediment after a wildfire disaster in California, a new remote-control surveying boat in Massachusetts, hypersaline lake sediments in the Dominican Republic, and much more.
