				<media:description><![CDATA[This low-level helicopter survey is designed to remotely study geologic units that lie below land surface. It is part of an ongoing USGS program to identify features such as changes in rock types, ultimately providing a better understanding of the geology and hydrology of the area. 

Operated by experienced pilots who are specially trained for low-level flying, the helicopter flies in a pattern of closely spaced, parallel lines at low heights above ground.  The instruments are housed in a tube suspended under the helicopter.

				<media:description><![CDATA[The Geologic Map of North America is a product of GSA's Decade of North American Geology (DNAG) project. At a scale of 1:5,000,000, this map covers ~15% of Earth's surface and differs from previous maps in several important respects: it is the first such map to depict the geology of the seafloor, the first compiled since the general acceptance of plate-tectonic theory, and the first since radiometric dates for plutonic and volcanic rocks became widely available. It also reflects enormous advances in conventional geologic mapping, advances that have led to a significant increase in the complexity of the map. The new map, printed in 11 colors, distinguishes more than 900 rock units, 110 of which are offshore. It depicts more than seven times the number of on-land units as are shown on its immediate predecessor, as well as many more faults and additional features such as volcanoes, calderas, impact structures, small bodies of unusual igneous rocks, and diapirs.]]></media:description>

These tripods recorded data quantifying the currents, waves, turbidity, temperature and salinity at several levels near the seafloor between January and April 2009. More information about the oceanographic measurements typically made by the USGS sediment transport group is available at http://woodshole.er.usgs.gov/pubs/of2007-1194/.
