This site is designed to provide information on federal interagency and cooperative developments related to coastal sand and gravel resources and management issues along the Atlantic continental margin.
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.
This publication focuses on the geological framework and sedimentary processes of the Lake Pontchartrain Basin and provides links to interactive tools, regional research, and sediment data in GIS formats for display and analysis.
Report of completed reservoir sediment studies in Kansas using a combination of bathymetric surveying, sediment coring, chemical analysis, and statistical analysis to understand the quantity and quality of deposited sediment.
Overview of studies of marine sediment on the continental shelf south of Los Angeles contaminated with DDT and PCBs from past sewage effluent discharges with links to research on Santa Monica Bay, Los Angeles Shelf and Palos Verdes Peninsula.
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
This web site is an outgrowth of an agreement between the USGS and the New England Aquarium, designed to summarize and make available results of scientific research. It will also present educational material of interest to wide audiences.
Overview with links to studies on the effects of human activity on the San Francisco estuary with loss of historic fresh and saltwater tidal marshes reducing habitats, introducing contaminants in waste, and creating dredging problems.
Field methods, topics of investigation, shoreline changes, publications, and satellite imagery related to geologic and hydrologic processes affecting Lake Pontchartrain and adjacent lakes which form a large estuary in the Gulf Coast region.
Proxy methods allow us to estimate ancient ocean temperatures but only if the method is calibrated using modern samples for which we measure the temperature. This is a proxy method using a sediment trap to collect planktonic foraminifera.
Overview of Klamath ecological research and links to USGS Klamath studies on ground water, nutrients, sediment oxygen demand, and fish response to water quality, sucker ecology, publications, bibliographies, and data.
Characteristics of recent tsunami deposits, with the knowledge we have about the events that caused them, give us ways to recognize ancient deposits of this type and infer characteristics of those ancient tsunamis as well.
Description of research studies of the Lake Roosavelt-Upper Columbia area on contaminants and effects on environmental health with links to publications and products, partners, related links, project summaries, and contacts.
The U.S. Geological Survey established a sediment trap in the northern Gulf of Mexico to collect time-series data on the flux and assemblage composition of live planktic foraminifers. This report provides an update of the 2008 time-series data to include
Project is designed to integrate studies from a number of researchers compiling data from terrestrial, marine, and freshwater ecosystems within south Florida. Links to publications, maps, posters, and data of studies.
Report on the status of the biota and ecological factors of the inland lakes of the Great Lakes Cluster Parks: Indiana Dunes, Sleeping Bear Dunes,and Pictured Rocks National Lakeshores and Isle Royale and Voyageurs National Parks. (PDF file, 321 p.)
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.
Overview of interdisciplinary research on the Tampa Bay estuary of the Gulf of Mexico with links to digital library, interactive mapping, reports, posters, water chemistry maps, meetings and conferences, scientist directory, and field trips.
Summary of part of the USGS interdivisional Mississippi Basin Carbon project that will study the changes in climate and the environment through carbon cycle changes recorded in lake sediments in the Upper Mississippi River Basin.
