Station 01124151 Quinebaug River West Thompson Connecticut. The photo shows the orifice line that senses the river stage. The orifice is out of water, so we were not able to collect stage or discharge data.

Researchers instruct volunteers on how to collect dragonfly larvae in Glacier NP as a part of the Dragonfly Mercury Project.

Safety is a top priority. USGS staff recently improved access to field sites at the Herring River estuary within the Cape Cod National Seashore to provide safer paths through a phragmites wetland.

Merrimack River near Aiken St Bridge, Lowell, Massachusetts (USGS ID: 010965985).

The site is one of the Merrimack project water quality sampling and monitoring stations.

Instruments continue to collect vital data during workplace closures. Here staff perform maintenance on an eddy flux tower located within a phragmites wetland at the Cape Cod National Seashore. The instruments on this tower measure methane and CO2 fluxes related to plant and soil processes day in and day out for the entire year.

USGS hydrographer Dave Thompson makes a near-peak flood measurement off a bridge at Tenmile River in Tusten, New York.

When wetland plants in the northeast emerged this spring, USGS scientists were working from home and unable to start many planned research activities. However, many instruments were already deployed and continued to collect information critical to USGS research.

Locations of multichannel seismic reflection profiles (in black), collected during cruise FA2020-14. The profiles are overlain on colored and shaded multibeam bathymetry, Lidar topography (green and white) and near-shore bathymetry (darker blue), and NOAA coastal relief model (light blue and white).

Hydrologic technician measured the streamflow of ice-covered rivers in Northern Maine as part of the North Index Trip. Certain gages are considered "Index" sites because they make for good references when comparing discharges of nearby streamgages, especially in frozen conditions.
