Geophysical surveys at the land surface help scientists explore the subsurface geology. Here geologists collect geophysical data using geophones. In the resulting geophysical profile, colors highlight key horizons.

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species.

Geochemists use platinum, silica, and ceramic crucibles, shown here in a glass container called a desiccator. Silica is used because it is resistant to extremely high temperatures and because it is chemically inert. Silicon, linked up with a pair of oxygen molecules as silicon dioxide, is known as silica.

When you’re planning to explore someplace new, it’s always a good idea to bring a map so you can avoid dangerous terrain. This is true whether you’re heading out for a hike on Earth or you’re landing a rover on Mars!

William T. Pecora, Director of the USGS from 1965 to 1971, is largely responsible for two major contributions to science in the public interest: the creation of a national earthquake research center at the USGS facility in Menlo Park, CA, and the Landsat series of Earth observing satellites.

Founded by the Spanish in 1565, St. Augustine, Florida is the oldest settlement of European origin in the United States. The Spanish fortress of Castillo de San Marcos in St. Augustine was built from 1672-1695 and is made of coquina, a soft, impact-absorbing stone composed of sea shells.
