Erosion of a sea stack over 100 years [More info]
Series of photographs showing the demise of Jump-off Joe, a sea stack at Nye Beach, Newport, Oregon from 1890 as a result of erosion.
PDF Evidence of multidecadal climate variability in the Gulf of Mexico [More info]
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.
Geologic history of Cape Cod, Massachusetts [More info]
Describes the history, geologic changes (including the glacial formation and sea level changes), and geologic mapping of Cape Cod, Massachusetts.
GLORIA Mapping Program [More info]
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.
Gulf of Maine internet map [More info]
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.
Gulf of Mexico Climate-History Calibration Study [More info]
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.
Hydrates cruise in the Gulf of Mexico [More info]
Investigation of the upper- and middle continental slope of the Mississippi Canyon, including the Gulf of Mexico, for the distribution of gas-hydrate deposits with links to a DEM image map, bathymetry data, and research technology.
PDF Inventory and protection of salt marshes from risks of sea-level rise at Acadia National Park, Maine [More info]
Will salt marshes survive if sea level rises quickly? The answer depends on whether the areas surrounding them can allow salt marsh fauna and flora to migrate there. Local topography, both natural and manmade, is the main factor limiting this migration.
Long Island Sound [More info]
Long Island Sound interactive map with GIS datasets and sonar imagery.
Long Island Sound sidescan sonar mosaics [More info]
Sidescan sonar image, surficial geologic interpretation, and bathymetry of the Long Island Sound sea floor.
