Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Town Neck Beach, a highly trafficked local beach in Sandwich Massachusetts with parking lot, boardwalk, and state maintained sand and vegetation placement. USGS personnel collected natural (RGB) color images, LiDAR, and ground control points starting in December 2023 to support multiple science...

In July 2022, the U.S. Geological Survey (USGS) and the University of Maryland's Chesapeake Biological Laboratory conducted a study, USGS Field Activity Number (FAN) 2022-020-FA, in Chesapeake Bay to quantify greenhouse gas fluxes from the largest estuary in the United States. The team investigated the environmental factors that control the distribution and exchange of methane and carbon...

The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST v3.8; Warner and others, 2010; Warner and others, 2019) modeling system was used to simulate ocean circulation, water levels, waves, and sediment transport that occurred during Hurricane Michael (2018). Simulations were performed with coupled and concurrent ocean and wave models simulated on a series of refined, cascading grids...

These lidar point clouds and images cover, in high detail, the terrain at Great Sippewissett Marsh, Cape Cod, MA on November 2nd, 2022. USGS researchers tested different sensors that collected lidar and images for photogrammetry point cloud data using Uncrewed Aerial Systems (UAS) to look at differences in coverage and elevation accuracy. The lidar data were acquired with a YellowScan...

Marsh migration potential in the Chesapeake Bay (CB) salt marshes is calculated in terms of available migration area for each marsh unit defined by Ackerman and others (2022). The space available for landward migration is based on the NOAA marsh migration predictions under 2.0 feet of local sea-level rise (SLR). The migration space is further divided by National Hydrography Dataset (NHD)...

A watershed in the coastal Canadian Arctic was sampled for dissolved carbon dioxide and methane concentration and stable carbon (carbon-13) isotopes to trace the transport, production, and consumption of carbon dioxide and methane during the spring thaw across a lake to bay transect. Two field campaigns were conducted in June 2022 and June-July 2023 out of the Canadian High Arctic...

Determining how much methane and carbon dioxide cross the sea-air interface is critical when assessing marine greenhouse gas fluxes. This assessment is particularly important on Arctic Ocean continental margins, where rapid climate change is thawing glacial ice and permafrost; reducing sea ice cover; and changing water temperatures, salinities, nutrient loads, and ocean currents. This...

In November 2021, the U.S. Geological Survey collected high-resolution multibeam sonar data in the vicinity of Eel Pond, in Woods Hole, Massachusetts using a dual-head Teledyne Seabat T20-R multibeam echo sounder (MBES). The main objective of this survey was to evaluate new sonar system features prior to their use in future field activities. In addition to bathymetry and relative...

Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Marsh Island, a salt marsh restoration site along New Bedford Harbor, Massachusetts. Remediation of the site will involve direct hydrological and geochemical monitoring of the system alongside the UAS remote sensing data. Baseline conditions were evaluated in October 2023, and future data...

This data release contains coastal wetland synthesis products for the Atlantic-facing New Jersey salt marshes. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, and tidal range, are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S...

The U.S. Geological Survey (USGS), in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration (NOAA), has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The interpretive datasets and source information presented here are for quadrangle 2, which is one of 18...

Two DJI M600 small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over various locations within the Lower Darby Creek Superfund Site and the adjacent John Heinz National Wildlife Refuge (NWR). Datasets included natural (RGB) color images, multispectral images, and LiDAR Point Clouds (LPCs). These data were processed to produce high resolution digital...
