Developing bare-earth digital elevation models from structure-from-motion data on barrier islands, Dauphin Island, AL, 2018-2019

This U.S. Geological Survey data release includes bare-earth digital elevation models (DEMs) that were produced by removing elevation bias in vegetated areas from structure-from-motion (SfM) data products for two sites on Dauphin Island, Alabama. These data were collected in the late fall of 2018 and spring of 2019. In addition to the bare-earth DEMs, this data release also includes vegetation mas

Barrier island vegetation and elevation survey, Dauphin Island, AL, 2018-19

Vegetation and elevation survey data were collected in 4-square-meter quadrats via Real-Time Kinematic GPS from September 9, 2018 to April 17, 2019 on Dauphin Island, AL. Vegetation data included total percent herbaceous cover, percent cover by plant species, and mean height of vegetation within the quadrat. The percent cover by species was used to determine the dominant species for the plot.

EverSparrow model scripts and outputs

EverSparrow is a spatially explicit Bayesian model of Cape Sable Seaside Sparrow (Ammospiza maritima mirabilis; CSSS) presence that quantifies the interdependent relationships between a range of environmental factors and CSSS presence. Using hydrologic conditions such as mean 4-year hydroperiod and maximum depth, fire occurrence history, and vegetation structure throughout the range of CSSS, EverS

Morphological measurements of Antillean manatees from Guantanamo Bay, Cuba

The data were collected by U.S.G.S. biologists and their partners during several field trips from March 2013 to April 2014 in Guantanamo Bay, Cuba. Data were collected during the manatee health assessments. The U.S. Geological Survey's Sirenia Project is a federal research effort focusing on manatee biology and ecology with a long history of studies in the U.S., Puerto Rico, and the international

Red Lionfish DNA data collected from Florida, USA and around the invasive distribution from 2007 to 2016

Red lionfish (Pterois volitans) have become a successful invasive predator across the Northwestern Atlantic, Caribbean, and Gulf of Mexico (GoM). Previous investigations have identified the southeast coast of Florida as the original site of introduction, but no region-wide genetic study has directly addressed the question of introduction location(s). This dataset includes previously unpublished re

Green turtle (Chelonia mydas) stable isotope signatures from Dry Tortugas National Park, Florida, sampled 2008-2015

Stable carbon and nitrogen isotope data from green turtles sampled at Dry Tortugas National Park, FL. Dataset includes: date collected, length, tissue type, percent of isotopes, calculated values of isotopes.

Tagging date, site, turtle size, and migration and foraging behavioral data for loggerheads (Caretta caretta) nesting at three sites in the Gulf of Mexico from 2011–2019

Tagging information, including migration and foraging behavioral data, for female reproductive loggerhead marine turtles (Caretta caretta) that were satellite tagged at nesting beaches at Gulf Shores (Alabama [AL]), Dry Tortugas National Park (DRTO, Florida [FL]), and Everglades National Park (ENP, FL) from 2011–2019. Variables include the tagging date, tagging site, the curved carapace length-not

An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Conterminous United States (2014-2018)

This USGS Data Release represents geospatial data sets which were created to produce an Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the conterminous United States (2014-2018). The following listed image products were generated 1) Annual spatial datasets (rasters) from 2014 to 2018 each containing 4 bands (Band 1: Unvegetated land fraction; Band 2: Vegetated land fraction; Band 3:

Riverine Sand Mining/Scofield Island Restoration (BA-40): 2014 habitat classification

This data set includes mosaicked aerial photographs for the Riverine Sand Mining/Scofield Island Restoration (BA-40) project for 2014. This data is used as a basemap habitat classification. If repeated, it can also serve as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration ef

Grand-White Lake Landbridge Protection (ME-19): 2018 land-water classification

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 arresting

Pecan Island Terracing (ME-14): 2018 Land-Water Classification

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.
