This product depicts the spatial coverage of seagrass beds from 0.5-m color-infrared orthoimagery for Ship Island, Mississippi from early fall of 2021. 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. First release: May...

Continuous water quality sensor data were collected at USGS 292939089544400 Wilkinson Bayou cutoff north of Wilkinson Bay, LA gage. Field water quality measurements were collected using a YSI EXO2 water quality sonde equipped with a data logger to capture hourly data using sensors for measuring water temperature, specific conductance, salinity, pH, oxidation and reduction potential (ORP)

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

The dataset contains spectral indices values calculated from Landsat imagery, normalized difference vegetation index (NDVI) and delta normalized burn ratio (NBR, deltaNBR). The spectral indices were computed for 1472 forested sites in the Glacier National Park, Montana, over the 1984-2021 period, in areas that were burned or not burned during the Robert Fire of 2003.

The data release records observations of insect crossing in the Lower Rio Grande National Wildlife Refuge along the U.S.-Mexico Border from 20230307 to 20240125. The barrier appears to be a partial barrier to some types of pollinators attempting to cross during high wind.

One of the largest and most expensive restoration efforts in the world is occurring in the Everglades, a sub-tropical freshwater wetland system located in southern Florida. This unique ecosystem supports several endemic and endangered species, provides flood control for Florida’s large urban population, and provides water for both agriculture and drinking supply within the state. The...

This dataset contains study results examining the effect of road mortality on migrating salamanders along the Natchez Trace Parkway in Mississippi from 2012-2013. A combination of methods were used to assess the movement of salamanders to and from the breeding pond. Environmental variables such as air and water temperature, water salinity, and relative humidity were also collected during...

This dataset contains data from time-constrained visual encounter surveys conducted in the Atchafalaya River Basin in South Central Louisiana from February 2008 through July 2016. In addition, it contains vocalization data collected concurrently with the visual encounter surveys and data on presence of tadpoles and larvae. All participants in surveys are included in the dataset...

This data release contains the R code to run an integrated population model (IPM) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis), a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA, and provides the parameter estimates from the model. The IPM synthesizes thirty years (1992-2021) of range-wide surveys, mark-resight, and...

This data release contains a bibliography of U.S. Geological Survey publications on carbon and greenhouse gas research. Publications between 2014 and 2024 were identified using search terms such as: carbon, greenhouse gas, methane, nitrous oxide, emission, sequestration, and primary productivity. Publications were primarily sourced from the USGS Publications Warehouse (https://pubs.usgs...

The majority of landbirds breeding in eastern North America migrate through the Gulf of America (Gulf of Mexico; hereafter Gulf) region during spring and fall. Rarely do migratory landbirds make nonstop flights between breeding and non-breeding areas, rather they stopover in habitats (a.k.a. stopover sites) en route to rest and refuel. Forested habitats in the northern Gulf region...

This TX_LowerRioGrande_D22 project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at an aggregate nominal pulse spacing (ANPS) of 0.18 meters (30 ppsm) and 0.35 meters (8ppsm). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification 2022 Rev A. The data was developed based...
