Protected Areas Database of the United States (PAD-US) 2.1 - World Database on Protected Areas (WDPA) Submission (ver 1.1, April 2021) Protected Areas Database of the United States (PAD-US) 2.1 - World Database on Protected Areas (WDPA) Submission (ver 1.1, April 2021)
The United States Geological Survey (USGS) - Science Analytics and Synthesis (SAS) - Gap Analysis Project (GAP) manages the Protected Areas Database of the United States (PAD-US), an Arc10x geodatabase, that includes a full inventory of areas dedicated to the preservation of biological diversity and to other natural, recreation, historic, and cultural uses, managed for these purposes...
Supporting data for Physical and chemical evidence for an aeolian component of paleowetland deposits Supporting data for Physical and chemical evidence for an aeolian component of paleowetland deposits
The Las Vegas Formation (LVF) is a well-characterized sequence of groundwater discharge (GWD) deposits exposed in and around the Las Vegas Valley in southern Nevada. Nearly monolithologic bedrock surrounds the valley and provides an excellent opportunity to test the hypothesis that GWD deposits include an aeolian component. Mineralogical data indicate that the LVF sediments are dominated...
Cross-reef wave and water level data from coral reef environments (ver. 4.0, June 2025) Cross-reef wave and water level data from coral reef environments (ver. 4.0, June 2025)
Coral reefs provide important protection for tropical coastlines against the impact of large waves and storm damage by energy dissipation through wave breaking and bottom friction. However, climate change and sea level rise have led to growing concern for how the hydrodynamics across these reefs will evolve and whether these changes will leave tropical coastlines more vulnerable to large...
Jurabi, Exmouth, Western Australia, 2016 Coral Reef Circulation and Sediment Dynamics Experiment Jurabi, Exmouth, Western Australia, 2016 Coral Reef Circulation and Sediment Dynamics Experiment
Carbonate reefs are a major source of sediment for coastlines in much of the tropical regions of the world, contributing to significant shoreline accretion and beach nourishment. A collaborative experiment between the U.S. Geological Survey and the University of Western Australia was conducted on Ningaloo Reef, northwest Australia, to investigate this problem and determine the primary
Stream Temperature, Dissolved Oxygen, Conductivity, and Photosynthetically Active Radiation (PAR) in River Basins of Northwest Alaska, 2017-2024 Stream Temperature, Dissolved Oxygen, Conductivity, and Photosynthetically Active Radiation (PAR) in River Basins of Northwest Alaska, 2017-2024
This dataset includes continuous data on water temperature, dissolved oxygen, conductivity, and photosynthetically active radiation (PAR) from low-order streams and main-stem rivers in Northwestern Alaska. Water temperatures were determined using a HOBO Water Temp Pro v2 (Onset Computer Corporation, Bourne, MA, USA) with ±0.2 °C accuracy. Dissolved oxygen was measured using HOBO U26...
Monitoring mortality of brown treesnakes fed an oral toxicant (acetaminophen) in an external bait placement dosing technique in the laboratory, 2017 Monitoring mortality of brown treesnakes fed an oral toxicant (acetaminophen) in an external bait placement dosing technique in the laboratory, 2017
Accidentally introduced to Guam, the brown treesnake (BTS) has extirpated nearly all native forest birds and imposed cost millions of dollars in economic damages annually. Acetaminophen is a safe and effective oral toxicant for invasive BTS, and an automated aerial delivery system (ADS) has been developed for landscape-scale distribution and snake suppression. An 80 milligram dose has...
