Hurricane Florence numerical modeling: The Weather Research and Forecasting Model Hydrological modeling system (WRF-Hydro) is used to simulate surface and subsurface flows on land.

Example from development of an atmospheric model for Hurricane Florence. The animation shows the changing atmospheric pressure and wind fields during the storm as simulated by the model. Arrows display wind direction, colors indicate atmospheric pressure ranging from 97,500 pascals (red) to 102,460 pascals (blue).

The AIM group collaborated with the National Uncrewed Systems Office in fieldwork at the South Cape Beach Marsh in Waquoit Bay, Massachusetts to test our newly acquired Ocean HDX Miniature Spectrometer, a modified laboratory spectroradiometer, against the much costlier industry standard product.

The USGS, including scientists from the Woods Hole Coastal and Marine Science Center, participated in the multiagency DUNEX (During Nearshore Event Experiment) project in the Outer Banks of North Carolina, September through October 2021. Maps of the beach were made at regular intervals.

Two video cameras are temporarily mounted on a dune at Pea Island National Wildlife Refuge on the Outer Banks of North Carolina. The cameras are imaging the southern DUNEX experiment site and are designed to have a stereo view of the beach and potential overwash path until late October. Instruments from the U.S.

Two high-resolution, digital cameras were mounted on towers overlooking the beach, dunes, and instrument arrays in the Outer Banks of North Carolina on September 18, 2021, as part of the DUring Nea

Researchers from the USGS and North Carolina Universites set up their equipment on installed poles stretching from the dune to the surf zone.

To install instruments offshore professional divers were hired to work alongside USGS personnel. Here, long segments of pipe are jetted into the seafloor to which instruments will be attached to measure offshore oceanographic conditions.

USGS researcher Jenna Brown takes a measurement with a real time kinematic GPS receiver, this will give her an accurate position and height of the aluminum pole beneath it, which will have mutliple instruments attached to it to measure water flow and elevation changes.

USGS scientists mounted this high-resolution digital camera on an observation tower in the dune at the U.S. Army Corps of Engineers Field Research Facility near Kitty Hawk, North Carolina. The camera overlooks the beach, dune, and an instrument array, and collects images throughout calm and storm conditions.
