All types of processes involving geological structures.
Ground-shaking hazard from earthquakes [ More info] Postcard available for downloading and printing.
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.
