New Hampshire is in the temperate broadleaf and mixed forests biome and is the state with the highest percentage of timberland area in the country. Much of the state, in particular the White Mountains, is covered by the conifers and northern hardwoods of the New England-Acadian forests. New Hampshire also has the shortest ocean coastline of any state in the United States, approximately18 miles.
The New England WSC has initiated a series of seminars to highlight diverse hydrographic assignments.

The USGS and the New Hampshire Department of Transportation are conducting preliminary research into the causes of iron fouling in water at roadway construction sites where blasted bedrock is used as on-site fill material.
FEMA has requested USGS expertise in hydraulics, hydrology, and mapping to general Flood Insurance Maps for New England.
Currently, there are 16 designated rivers in New Hampshire in need of daily mean streamflow estimates for managing instream flows. Many of New Hampshire’s Designated Rivers have current and/or historical streamflow data that may be used to extend an existing streamgages streamflow record in time through record extension techniques. Evaluating the feasibility of record extension techniques to...
The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

NOAA's National Water Model (NWM) represents the next generation of river forecasting by NOAA. The NWM is based on the National Hydrography Dataset at a scale of 1:100,000 and is being developed to provide continuous modeled river flows for all 2 million plus river reaches in the model.
The Seabird Research Program at PWRC is focused on studying the ecology of species present across the Atlantic Coast. This program was a natural progression of PWRC's historic work studying the coastal ecology of wildlife in and around the Chesapeake Bay. We now focus on the three key areas on a variety of species: physiology, avoided bycatch, and movement ecology.

Concentrations of arsenic in water from public-supply and domestic wells in New Hampshire (2004-2006)
Groundwater samples from public and private drinking water wells throughout the state of New Hampshire were analyzed for total Arsenic (As). Samples were collected after pH, specific conductivity, dissolved oxygen, and water temperature had met stabilization criteria as outlined in the USGS National Field Manual (United States Geological Survey 2005).

Location data are censored to the county level.
USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map.

USGS field crews are deploying storm-tide and wave sensors today from Maine to Delaware to track and study a Nor’easter forecasted to begin tomorrow.
Significant flooding along the coast of Massachusetts occurred Thursday, January 4, 2018, caused by a powerful blizzard. Peak storm surge of approximately 3.00 feet occurred at the astro high tide; and, according to the National Weather Service, is the highest since records began at the Boston tide station in 1921.
A carbonatite here, a glacial moraine there, a zig-zagging fault or two, even a behemoth of a batholith. The geology of the 50 States is an enormous patchwork of varied forms, beautiful in their variance but challenging to present as a single map.
A high-tech buoy that monitors water quality in real time was just installed in one of New England’s most popular lakes, where in the future it will help with determining when swimmers should and shouldn’t be in the water.
