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.
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.
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.
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.
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.
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.
