States L2 Landing Page Tabs
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.

Climate Change, Hydrologic Responses and Impacts on Carbon Cycling as Inferred by Changes in Fluvial Dissolved Organic Carbon Fluxes
This project investigates the links between terrestrial and marine carbon cycling and fluvial transport of freshwater and dissolved organic carbon (DOC) to the near-coastal ocean. The project analyzes DOC export that integrates complex interacting processes in natural and human-impacted terrestrial and aquatic environments. Changes in DOC export may indicate changes in terrestrial ecosystem...
Geospatial Dataset of Wells and Attributes in the New England Groundwater Level Network, 2017
The drought of 2016 affected hydrologic conditions throughout New England. Responses of USGS groundwater observation wells to this event, however, were not uniform and were sometimes markedly different from site to site. Although USGS scientists were able to provide explanations for most of these situations, the event highlighted the need for additional well information to develop quantitative...

Development of Streamflow Record Extension Equations in New Hampshire
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...
Bird Banding Laboratory
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...
Nutrient Loads from the Upper Connecticut River Watershed
River-borne nutrients, especially nitrogen, contribute to water-quality degradation in Long Island Sound. The Connecticut River is the largest tributary to the Sound, and quantification of nutrient loads from the three upper States in the watershed, as well as the State of Connecticut, is essential for prioritizing efforts to improve the Sound’s water quality.

Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

The NWIS mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.
Interactively explore assessment summary information for continuous (unconventional) assessments conducted at the USGS from 2000-2018. The assessment results data used to generate this visualization can be downloaded here in Excel Format. These data represent all assessment results for Continuous Assessments only from 2000-2018.
The USGS Coastal and Marine Geology Program (CMGP) Internet Map Server is an interactive mapping service which allows the user to explore and download GIS data sets published by CMGP.

The National Water Information System (NWIS) web application provides access to real-time and historical surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.

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.

The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and NOAA with contributions from other federal agencies. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and Fall.

The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.

This portal contains U.S. Geological Survey (USGS) video and photography of the seafloor off of coastal California and Massachusetts, and aerial imagery of the coastline along segments of the Gulf of Mexico and mid-Atlantic coasts. These data were collected as part of several USGS Coastal and Marine Geology Program Seafloor Mapping projects and Hurricane and Extreme Storm research.

Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
A dataset of well information and geospatial data was developed for 426 USGS observation wells in New England. The active well network at the end of water year 2017, consisting of 247 wells, is shown on the interactive map. Water levels in the active network were measured monthly at 164 wells and continuously (15-minute to 1-hour measurement frequency) at 83 wells.

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.
