USGS collects terrestrial (barrier island) and marine (nearshore and estuarine) sediment cores to ground-truth geophysical observations in 2019. These cores are used to understand the history of barrier island formation and erosion.

The USGS is assessing the physical condition of coastal wetlands and how they may change in response to storms, sea-level rise, and human activity.

Though often less intense than hurricanes, extratropical storms (e.g., nor’easters) occur more frequently and their impacts can be striking. Here, several years after Hurricane Sandy, winter nor’easters eroded sediments from an artificial dune at Fire Island, NY and moved them onto the beach and shoreface. Such erosion created a steep vertical face, or scarp.

You have to be able to have a little fun when in the field. A colleague from the Washington State Department of Ecology hams it up while prepping for a beach survey with scientists from the USGS Pacific Coastal and Marine Science Center. The multi-agency surveys define sediment transport pathways and record coastal changes at the mouth of the Columbia River, where dams, stone jetties, navigation channels, and changes in upstream land use affect the sediment supply to beaches.

The SQUID-5 is an acronym for a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras. Developed by the USGS Pacific Coastal and Marine Science Center Marine Facility (MarFac), SQUID-5 is a towed surface vehicle with an onboard Global Navigation Satellite System (GNSS) and 5 downward-looking cameras with overlapping views of the seafloor. It was first field-tested in July of 2019 in the Florida Keys over a shallow-water coral reef. Here, some curious dolphins frolic nearby as SQUID-5 is towed from a boat.
