Walrus Haulout Aerial Survey Data Near Point Lay, Alaska Walrus Haulout Aerial Survey Data Near Point Lay, Alaska
This dataset consists of the complete set of processed aerial imagery and survey data from walrus haulouts collected by unoccupied aerial system (UAS) surveys near Pt. Lay, Alaska, during the autumn 2024 and 2025. The data include georeferenced optical three band (red, green, blue) aerial images and orthoimages derived from those aerial images through the standardized structure from...
Walrus Haulout Audio Recordings Near Point Lay 2024 Walrus Haulout Audio Recordings Near Point Lay 2024
This dataset consists of a complete set of audio recordings collected near a large walrus haulout at Point Lay, Alaska, during September of 2024. The recordings were collected using the Song Meter Mini 2 (Wildlife Acoustics, Inc., Maynard, MA) at two sites, one within 150 m of a large walrus herd resting on shore and one placed more than 4 km to the south of the herd directly under the...
Walrus Haulout Outlines Apparent from Aerial Survey Images Collected Near Point Lay, Alaska Walrus Haulout Outlines Apparent from Aerial Survey Images Collected Near Point Lay, Alaska
This dataset provides walrus haulout group outlines in a shapefile format and haulout area sizes in csv format. These data are based on visual interpretation of imagery from aerial surveys by a small uncrewed aerial system (sUAS) operated by the U.S. Geological Survey Alaska Science Center, over large groups of walruses resting onshore near Point Lay, Alaska during September of 2024 and...
Warming Tolerances for 34 Species of Anurans Native to the Southeast United States Warming Tolerances for 34 Species of Anurans Native to the Southeast United States
Identifying how close species are to their current upper thermal limits estimates species sensitivity to climate change (or the species ability to persist in place without changing). Process-based models like the NicheMapR mechanistic niche model (Kearney et al. 2019; https://doi.org/10.1111/ecog.04680) use a mass-balance approach to translate microclimate estimates into individual...
Water and algal chemistry measurements collected from the National Park Service's National Park of American Samoa (NPS-NPSA) Ofu Island unit Water and algal chemistry measurements collected from the National Park Service's National Park of American Samoa (NPS-NPSA) Ofu Island unit
Geochemical analysis of coastal springs and possible source waters were conducted in the National Park Service's National Park of American Samoa (NPS-NPSA) Ofu Island unit. Water samples were analyzed for dissolved nutrients, nitrate isotopes (delta-18-O and delta-15-N). Algae samples were collected and analyzed for delta-15-N and delta-13-C values.
Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023 Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023
This data set was collected throughout the Gallinas watershed in New, Mexico following the Hermit's Peak-Calf Canyon fires on April 6, 2022. The watershed has a history of mining and prospecting, which acts as an additional stressor to post-wildfire water quality and ecosystem health. Water samples were collected immediately post-fire. Water, sediment deposit and bed sediment samples...
Water Chemistry Data for Samples Collected at Groundwater Sites in the Midway-Sunset and Buena Vista Oil Fields Study Area, March 2018 to April 2019, Kern County, California Water Chemistry Data for Samples Collected at Groundwater Sites in the Midway-Sunset and Buena Vista Oil Fields Study Area, March 2018 to April 2019, Kern County, California
The California State Water Resources Control Board (State Water Board) initiated the Oil and Gas Regional Monitoring Program (RMP) to assess effects of oil and gas development on groundwater (GW) designated for any beneficial use. The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in...

Water classification of the Colorado River Corridor, Grand Canyon, Arizona, 2021—Data Water classification of the Colorado River Corridor, Grand Canyon, Arizona, 2021—Data
These data are a surface water classification map of surface water in the riparian corridor of Grand Canyon between Glen Canyon and Pearce Ferry, Arizona, published in ESRI shapefile format. The map was classified from 0.2 m resolution, multispectral imagery (Sankey and others, 2024) and are the same spatial resolution as the imagery. In order to differentiate between the boundary...
Water Inundation Dataset from Synthetic Aperture Radar (SAR): Jim Foot Key, FL Water Inundation Dataset from Synthetic Aperture Radar (SAR): Jim Foot Key, FL
This dataset is derived from Synthetic Aperture Radar (SAR) data collected between July 2022-December 2024 and focuses on water inundation patterns on Jim Foot Key, located within Florida Bay. The dataset includes 13 TIFF files at 0.5 meter-3 meter horizontal resolution, that have undergone preprocessing and water thresholding methods to identify areas of inundation. These analyses were...
Water level data from vertical French drains in South Miami Heights, Florida: August to October 2017 and February 2019 to February 2021 Water level data from vertical French drains in South Miami Heights, Florida: August to October 2017 and February 2019 to February 2021
In the South Miami Heights area of Miam-Dade County, vertical French drains (VFDs) are drainage structures that collect and promote infiltration of runoff from streets, sidewalks and saturated surfaces. The VFDs consist of a shallow rectangular cement inlet connected to an approximately 9-inch diameter and 7-feet-deep hole. The vertical holes are not filled, they are cut directly into...
Water level, salinity, and elevation data at Turtle Bayou Mitigation Area of Bayou Sauvage National Wildlife Refuge, 2025 (ver. 2.0, January 2026) Water level, salinity, and elevation data at Turtle Bayou Mitigation Area of Bayou Sauvage National Wildlife Refuge, 2025 (ver. 2.0, January 2026)
Bayou Sauvage National Wildlife Refuge (BSNWR) is an urban refuge in southeastern Louisiana that has been altered extensively due to human impacts. As a result, the hydrology of the impounded (interior) marshes within the BSNWR has been disrupted due to obstructions such as spoil banks, levees, and water control structures that affect the gradient and fluctuation of water surface...
