Locations of survey points, a photographic record of each site, field observations of vegetation cover and descriptions of oil coverage in the water and on plants, including measurements of the distance of oil penetration from the shoreline.
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.
Monitoring soil temperature, soil moisture, air temperature, and overall thickness of the soil and sediment that is above the permafrost, therefore undergoing freeze-thaw cycles. Climate change may affect this active layer; we want to know how it does.
This unusual form of hydrocarbons can alter the thermal properties of host sediments; the analysis presented here helps us understand how those sediments might behave under natural or human-induced changes in the environment.
Information on aquifers in upstate New York which consist of unconsolidated deposits of sand and gravel that occupy major river and stream valleys or lake plains. Links to aquifer maps at scales 1:24,000 or 1:250,000 and cooperative publications.
Grain-size analysis of marine sediments of the U.S. eastern coast with sampling and lab methods, surficial sediment database in three formats (Excel, Dbase IV, ASCII), and use of geographic mapping tools for visualizing sediment data layers.
Describes and provides links to USGS research in the location of the estuary and coast of Long Island, New York, to map the sea floor and to study sediment transport, contaminants, and sand resources and coastal vulnerability.
This booklet presents a generalized summary of the nature, workings, publications, and hazards of the common types of volcanoes around the world, along with a brief introduction to the techniques of volcano monitoring and research.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.
