Nontidal network mapper
The nontidal network mapper is a story map that provides the primary findings for nitrogen, phosphorus and suspended-sediment trends, and gives the user tools to further examine the results for river basins and individual sites. Data used in the mapper, and the methods used to compute trends and loads, can also be accessed from the tool.

Analog dial gage (left) and a digital linear potentiometer (right)
An analog dial gage (left) and a digital linear potentiometer (right with blue barrel) used to measure land-surface movement in response to aquifer system deformation at the USGS Nansemond extensometer. The potentiometer is the primary instrument for the extensometer with a resolution of about 0.00001 feet (0.003048 millimeters) and a travel range of 0.328084 feet (100
