Data

Dataset of sediment macrofaunal communities, geochemistry, and grain size associated with chemosynthetic and soft-sediment habitats along the Cascadia margin, Pacific Ocean, in 2019.

To support the development of more accurate hurricane coastal impact models, we created a dataset containing an inventory of information sources of hard shoreline structures — including seawalls, groins, bulkheads, and breakwaters — for each U.S. state along the Gulf of America and Atlantic coasts. The shoreline structure inventory was developed initially from internet searches of open...

The U.S. Army Engineer Research and Development Center, in collaboration with the U.S. Geological Survey Wetland and Aquatic Research Center, collected hydrographic data to investigate sediment exchange between a back barrier marsh and open embayment through a tidal creek near Avalon, NJ, between July 2021 and August 2022. Data collected include time-series measurements of current...

Data in this release include oviposition, pipping, body size, and environmental temperature observations for three wild adult female Burmese pythons (Python molurus bivittatus). Data are from two individuals that were free-ranging (Pythons # 1 and 2) in Big Cypress National Preserve, Collier County, Florida, USA and one wild-caught individual (Python #3) placed in an outdoor enclosure on...

This data release contains Global Navigation Satellite System (GNSS) measurements acquired across five Texas coast National Wildlife Refuges in 2024. These data will be used to establish vertical control and tie rod-set elevation table (RSET) data to the National Spatial Reference System (NSRS) and National Vertical Datum of 1988 (NAVD88). Data from the RSETs will be used to determine...

A process-driven biogeochemistry model, Wetland Carbon Assessment Tool - DeNitrification-DeComposition model (WCAT-DNDC) was validated and applied to examine the responses of daily net ecosystem exchange (NEE), net primary productivity (NPP), ecosystem respiration (ER), methane (CH4) and nitrous oxide (N2O) emissions in the Lake Maurepas swamp forests under dry (2011), normal (2019), and...

Demographic and morphological data from an adult female Burmese python and a clutch of hatchlings produced July 2024 in Big Cypress National Preserve in southern Florida.

This product depicts the spatial coverage of seagrass beds from 0.5-m color-infrared orthoimagery for Cat Island, Mississippi from early fall of 2023. Specifically, the map includes presence and absence of seagrass beds within a potential seagrass extent that was based on topobathymetric data. A minimum mapping unit of 4 square meters was used for this mapping effort. We did not have...

Nest and brood survival data for piping plovers at Edwin B. Forsythe National Wildlife Refuge

We examined the effects of local and landscape level metrics on Piping Plover (Charadrius melodus melodus) daily nest survival rates using a long-term dataset from coastal New Jersey. Local-level metrics thought to be important determinants of nest success were collected from 1993 to 2016. Landscape metrics were examined over a from 2006 to 2016.

This dataset contains shorebird survey data conducted before (pre) and after (post) barrier island restoration of Cat and Ship Island, Mississippi. The Mississippi barrier islands provide critical habitat for migratory and resident shorebirds, including many federally threatened and endangered (T&E) species. Long-term monitoring of shorebirds before and after restoration is essential to...

To enhance hurricane coastal impact models, we developed 1-m land cover maps for the coastal portions of states along the Gulf of America and Atlantic coasts using recent (2018–2020) high-resolution orthoimagery and moderate-resolution land cover maps. Our first step was to develop land cover maps with three classes (vegetated, unvegetated, water) using recently acquired 1-m orthoimagery...
