This is a sample of rutile, one of the primary mineral sources of titanium. While as a metal, titanium is well known for corrosion resistance and for its high strength-to-weight ratio, approximately 95% of titanium is consumed in the form of titanium dioxide (TiO₂), a white pigment used in paints, paper, and plastics.

The use of acoustic Doppler current profilers (ADCPs) from a moving boat is now a commonly used method for measuring streamflow. The technology and methods for making ADCP-based discharge measurements are different from the technology and methods used to make traditional discharge measurements with mechanical meters.

USGS research oceanographers Jenna Brown and Joe Long installed this video camera atop the Shoreline Island Resort hotel in Madeira Beach, Florida. Starting in February 2017, the camera has recorded video for 17 minutes every hour during daylight hours.

In July of 2016, a team from the Climate and Land Use Research and Development Program took a trip to South Carolina to study outcrops of the “Canepatch” and “Socastee” formations along the Intra-Coastal Waterway, near Myrtle Beach. The age of these fossiliferous marine units has been controversial for several decades.
