As part of the Remote Sensing of Coastal Change and Florence Supplemental projects we have been developing novel workflows for repeat-mapping of ­­­coastal environments at order decimeter resolution over up to hundreds of kilometers in a single day, using Structure-from-Motion photogrammetry or SfM, from crewed aerial platforms.

USGS samples water within wetlands to understand which environmental drivers impact carbon cycle and sediment accretion. Here USGS staff (Jennifer O'Keefe Suttles) pumps water from at Phragmites wetland, Mashpee, MA, to analyze at the Woods Hole Coastal and Marine Science Center Environmental Geochemistry lab.

Tropical Storm Eta affected beaches along Florida's Gulf Coast in November 2020. Some dunes were eroded up to several feet due to the high water levels associated with the storm. Madeira Beach is home to many people and animals, and erosion events such as this can affect both habitat and infrastructure.

Tropical Storm Eta had effects on Florida's Gulf Coast beaches, including dune erosion and overwash. This image from the coast cam at Madeira Beach, Florida captured high water levels and resulting overwash of sand onto the patio of the Shoreline Resort.

An image of 24 June 2020 (B4) and prehistoric (P2) outlier rockfall boulders within the Mount Whitney Trailhead Campground. Boulder P2 is approximately 3 m tall. The blue dashed line indicates one of several tent sites affected by the 2020 rockfalls.

Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys. Pictured here is one of 30 stations located in in Dry Tortugas National Park.

This screenshot was taken from a video created for the virtual 2020 St. Petersburg Science Festival that discussed Coastal Change Hazards research at the USGS. Justin Birchler is seen walking up the beach with GPS equipment to measure the elevation of the beach.

Waves are the motion of the water's surface, usually caused by the transfer of energy from wind. Wave energy causes the water to move in a circular motion. The height and length of these waves combined with the slope of the beach influence how high the water can reach up on the coast.
