A geologic and oceanographic study of the waters and Continental Shelf of Gulf of the Farallones adjacent to the San Francisco Bay region. The results of the study provide a scientific basis to evaluate and monitor human impact on the marine environment.
By measuring the current and historical growth rates of coral skeletons, and using field experiments, we intend to find out whether rising atmospheric CO2 and rising sea levels will cause coral reefs to erode and cease to function.
New synoptic data from samples collected in the Arctic Ocean and insights into the patterns and extent of ocean acidification. This foundational geochemical information will help us to understand potential risks to Arctic resources.
Topics in Coastal and Marine Sciences provides background science materials, definitions, and links to give a common context for users from a variety of backgrounds. Coastal erosion was chosen as the first topic.
The report describes a strategy for monitoring, modeling, and research activities to support management decisions to improve water-quality conditions in the Mississippi River Basin, reduce hypoxia in the northern Gulf of Mexico, and improve conditions for
Analysis of sea-surface temperature in the Indian Ocean shows that warming correlates with east African rainfall; the effect on atmospheric convection and precipitation over the Indian Ocean is greater than that associated with El Niño (ENSO).
Downloadable files of digital bathymetry of U.S. waters, the Bering and Chukchi Seas, Bering Strait, and Gulf of Anadyr in polygon ARC/INFO. Coverage generated from both digital and paper bathymetry sources developed to support marine research.
Access to InfoBank, an online data catalog, to browse or retrieve coastal and marine geology program information, images, and data on gravity, bathymetry, seismic activity, magnetics, samples, facilities, cruises and equipment.
Describes the content metadata standard used by the Marine Realms Information Bank, a distributed geolibrary that catalogues and provides access to information about marine, coastal, and lake environments.
Use of diatoms in biostratigraphy, coastal and estuarine studies, paleoceanology, paleoliminology, earthquake studies, environmental quality and forensic studies. Includes listing of USGS diatom projects and links to other diatom websites.
Direct measurement of an important indicator of interannual variability is extended, using geological proxy measures, farther back in time to well before modern measurements were made. This tells us about the history of climate variability.
This updated global inventory reports on natural gas hydrate recovered or inferred from geophysical, geochemical, or geological evidence. Includes links to world location maps, inventories, references and posters. Also in PDF format files.
Downloadable data with software showing composite average ocean characteristics (sea-surface temperature and sea-ice concentration). Includes documentation, source code, data, and executable programs for Linux and Microsoft Windows.
GLORIA is a digital sidescan sonar capable of producing digital image maps of the sea floor from reflected sound waves. Site includes description of digital processing, mosaicking, and links to samples of image maps.
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.
Study of the effects on the Gulf of the Farallones National Marine Sanctuary resulting from the disposal of San Francisco dredged material and barrels of low-level radioactive waste with links to publications and atlas with digital images.
Bibliography of publications relating to the research of the United States Geological Survey, Woods Hole, MA dating from 1962 to the present with links to publications that are online. Listed by series and with a free text search option.
Brief description of the research program to inventory the natural resources of Monterey Bay National Marine Sanctuary with links to cruises, and publications and products, including an internet map server, imagery, and geologic descriptions.
Information on mollusks and uses of the identification of fossil mollusks in the fields of biostratigraphy, geochronology, paleocoeanography, paleoecology and ecosystems history. Links to experts and related USGS projects.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat.
Report on satellite imagery collected by the NOAA Advanced Very High Resolution Radiometer (AVHRR) on NOAA polar-orbiting weather satellites. Links are provided to imagery of north-central Gulf of Mexico and of the Lake Pontchartrain.
The Sediment Transport Instrumentation Facility at USGS Woods Hole Field Center maintains and deploys oceanographic instrumentation for the study of coastal and ocean circulation and sediment transport.
USGS project to understand coastal evolution and modern beach behavior; to identify and model the physical processes affecting coastal ocean circulation and sediment transport; and to identify sediment sources and construct a regional sediment budget.
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.
An introduction to three related USGS digital libraries: the general-purpose Marine Realms Information Bank (MRIB); the regionally focused Monterey Bay Science (MBS) Digital Library; and the topically focused Coastal Change Hazards (CCH) Digital Library.
Article from American Scientist on study of the San Francisco Bay estuary as a component of the global climate system showing that natural fluctuations might be mistaken for anthropogenic trends affecting waterflow and salinity.
Fact sheet on the sea-floor mapping facility at Woods Hole describing state-of-the-art technology used to produce accurate geologic maps of the sea floor and reporting on its data-acquisition, data-processing, and archiving capabilities.
