USGS pilot Sandy Brosnahan and Senate Pro Tempore Marc Pacheco discuss the use of Umanned Aerial Systems (UASs, also known as drones) to collect data in coastal environments.

Hill-shaded bathymetric, backscatter, and photographic data collected by NOAA and the USGS. Backscatter data give indications of seafloor character. In general, low-backscatter intensity (blue) corresponds to finer-grained material, whereas high-backscatter intensity (orange) corresponds to coarser substrate.

The USGS conducted surveys on the inner continental shelf of the Delmarva Peninsula (shown in green) to complement related datasets previously collected in the area by partners NOAA and BOEM. The inset map shows location of the study area.

Orthomosaic images of Matanzas, Florida, from (a) before and (b) after Hurricane Matthew, and (c) a digital elevation model (DEM) showing the associated topographic change. Note, these results were produced by applying Structure-from-Motion (SfM) to NOAA oblique photographs, but similar results can be obtained using UAS aerial imagery.

Gas hydrate (white material) binding together coarse-grained sediments made up of pebble-sized rocks. This sample was recovered during a project to explore permafrost-associated gas hydrates in Canada’s Mackenzie Delta.

USGS scientist Zafer Defne measures water and sediment movement at Forsythe National Wildlife Refuge, New Jersey. Defne is co-author with Neil Ganju of a 2017 study on how to estimate coastal salt marshes’ potential longevity, based on their sediment budgets and the ratio of open water to vegetation.

The USGS Utah Water Science Center and the Woods Hole Coastal and Marine Science Center conducted a collaborative geophysical research effort within Lake Powell, UT-AZ to map the bathymetry of the lake and characterize shallow sediment deposition near the mouths of the San Juan and Colorado Rivers.

Fish Creek wanders through the National Petroleum Reserve-Alaska, a 22.8 million acre region managed by the Bureau of Land Management on Alaska's North Slope. USGS has periodically assessed oil and gas resource potential there. These assessments can be found here.
