Massachusetts Wildlife Monitoring Project (2022 - 2024)

This volume's release consists of 143321 media files captured by autonomous wildlife monitoring devices under the project, Massachusetts Wildlife Monitoring Project. The attached files listed below include several CSV files that provide information about the data release. The file, "media.csv" provides the metadata about the media, such as filename and date/time of capture. The actual media files

Guam, Andersen Air Force Base housing area visual surveys for brown treesnakes (Boiga irregularis) and associated tree data, December 2019–November 2022.

This data was collected as part of a larger project to examine predator-prey interactions between invasive Brown Treesnakes (Boiga irregularis, predator) and native prey species at a study site located in a peri-urban area of Andersen Air Force base in Guam, USA. This dataset includes two datasets. One dataset contains 22 columns and includes data collected on Brown Treesnakes captured between 23

Hawaiian Islands habitat suitability models for highly invasive plants based on global and regional data for baseline climate scenario (1990-2009)

We created a comprehensive estimate of potential distribution for a subset of 17 ecosystem modifying invasive plants (EMIPs) in Hawaiʻi. This work uses methods that integrate a wide set of data sources including agency and citizen science data, but perhaps more importantly, the integration of regional and global distribution information for these species. We built three sets of ensemble species di

Kaloko-Honokōhau National Historical Park shrimp density and anchialine pool characteristics, 2017

This data release includes metadata and tabular data that documents counts of shrimp and measurements of field variables aimed to identify factors that affect the distribution and abundance of the uncommon anchialine pool shrimp Metabetaeus lohena at Kaloko-Honokōhau National Historical Park during 2017. The data set documents biological, chemical and physical attributes within 173 anchialine pool

Laboratory Optical Measurements From Discrete Surface Water Samples Collected During Water Quality Mapping Campaigns on the Illinois Waterway and Chicago Area Waterway Systems

Fluorescence and absorbance spectra were measured in discrete surface water samples collected during three sampling campaigns (Nov 2022, Mar/Apr 2023, Jul 2023) on the Illinois Waterway (IWW) and Chicago Area Waterway System (CAWS), which are the primary drainage of the Illinois River Basin (IRB). Water sampling was conducted concurrently with a boat-based water quality mapping effort using the Fa

Estimated crop irrigation water use withdrawals in San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin, Arizona for 2023

Observations of irrigated agricultural land within the San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin in Arizona. Crops were verified in situ twice in 2023, first on May 4th and again on Aug 15th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizo

Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2023

Observations of irrigated agricultural land within the Harquahala Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ three times in 2023, first on May 12th, then on Aug 24th, and finally on Sep 30th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 i

Sea Otter Aerial Survey Data from lower Cook Inlet and the outer Kenai Penisula, Alaska, 2002

This dataset consists of three tables related to abundance and distribution of northern sea otters (Enhydra lutris kenyoni) in lower Cook Inlet and the outer Kenai Peninsula, Alaska, based on data collected during a series of aerial surveys from May-Aug 2002. The dataset consists of: (1) sea otter counts along strip transects, (2) sea otter counts in Intensive Search Unit (ISU) within the transect

Data Release for Luminescence: Tyndall Air Force Base, Panama City, Florida estuarine sediment cores

As part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects, scientists from the U.S. Geological Survey (USGS) and St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map and characterize the stratigraphy of back-barrier bays near Panama City, Florida (FL) in June 2022. This data r

Estimated crop irrigation water use withdrawals in Ranegras Plain Groundwater Basin, Arizona for 2023

Observations of irrigated agricultural land within the Ranegras Plain Groundwater Basin in Arizona. Crops were verified in situ twice in 2023, first on May 10th and again on Sep 28th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with the Sentinel

Annual Nitrogen Load Estimates from Six Nonpoint Sources on Long Island, New York, from 1900 to 2019

This data release contains annual estimates of nitrogen load from six non-point sources across Long Island, New York, over a 120-year period (1900-2019). Estimated loads are gridded at a 500 x 500-foot square resolution and represent the total mass of nitrogen (N), in kilograms (kg), from six major sources—septic systems (SS), residential fertilizer use (RF), agriculture crop fertilizer use (AG),
