Description of Long Island Sound projects and links to research topics, data, publications, photos, and technology on sediment transport, sea floor mapping, contaminant sampling, sediment texture, and environmental issues.
Gulf of Maine regional overview interactive map depicting research activities of the U.S. Geological Survey showing surficial sample sites, bathymetry, continental margin and coastal areas.
Geological research of the Stellwagen Bank National Marine Sanctuary sea floor are presented in the form of maps, posters, fact sheets, sonar images, and bottom photographs.
Boston Harbor/Massachusetts Bay Studies research project conducted as part of Boston Harbor cleanup to predict the fate of contaminants and sediments introduced to Massachusetts' coastal waters from sources that include Boston sewage outfall.
Research findings and examples of application to real problems--chemical reactions between nitrate, iron, and oxygen can affect the mobility of trace amounts of arsenic.
The USGS in Augusta, Maine monitors river and ice conditions in areas of ice accumulation on the Kennebec River near Augusta providing real-time river stage data and real-time pictures of ice conditions at this location.
The 258 organic compounds in this assessment are man-made: pesticides, solvents, gasoline hydrocarbons, personal-care and domestic-use products, pavement and combustion-derived compounds. None were found in concentrations deemed dangerous at this time.
Mathematical models predict overall streamflow, runoff, subsurface flow, groundwater flow, and soil moisture in this area in response to four different greenhouse gas emission scenarios.

Proposed removal of dams will change the characteristics of stream flow and will affect fish that swim upstream to spawn. A mathematical model of the river flow tells us where the likely problems will be located and how the flow will change.
