Assessing Nest Attentiveness of Common Terns (Sterna hirundo) via Video Cameras and Temperature Loggers Assessing Nest Attentiveness of Common Terns (Sterna hirundo) via Video Cameras and Temperature Loggers

While nest attentiveness plays a critical role in the reproductive success of avian species, little is known regarding the nest attentiveness patterns of many species during incubation. However, improvements in both video monitoring and temperature logging devices present an opportunity to improve our understanding of this aspect of avian behavior. To evaluate the ability of these...

Assessing spatial variability of nutrients and related water quality constituents in the California Sacramento-San Joaquin Delta at the landscape scale: 2018 High resolution mapping surveys (ver. 2.0, October 2023) Assessing spatial variability of nutrients and related water quality constituents in the California Sacramento-San Joaquin Delta at the landscape scale: 2018 High resolution mapping surveys (ver. 2.0, October 2023)

The dataset documents the spatial and temporal variability of nutrients and related water quality parameters at high spatial resolution in the North Delta, Central Delta, and the Western Delta out to Suisun Bay in the Sacramento-San Joaquin River Delta of California, USA. The dataset includes nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved...

Assessing the impact of irrigation curtailment using Landsat satellite data: A case study in the Upper Klamath Lake basin Assessing the impact of irrigation curtailment using Landsat satellite data: A case study in the Upper Klamath Lake basin

The associated geotiff rasters represents the total actual evapotranspiration (ETa) from June through September for the years 2004, 2006, 2008-2010, and 2013-2016 for the entire Klamath Basin in southern Oregon. The ETa was created using Landsat imagery and the Operational Simplified Surface Energy Balance (SSEBop) model to estimate actual ET and the Python scripts to complete that...

Assessment of Field and Laboratory Methods for the Detection and Analyses of Cyanobacteria and Cyanotoxins in Texas Reservoirs Assessment of Field and Laboratory Methods for the Detection and Analyses of Cyanobacteria and Cyanotoxins in Texas Reservoirs

In cooperation with the Texas Commission on Environmental Quality (TCEQ), the U.S. Geological Survey (USGS) utilized various field and laboratory methods to determine the presence and concentration of cyanobacteria, cyanotoxins, and taste-and-odor compounds in Texas water bodies. This data release documents the results from water-quality samples collected from 41 water bodies in Texas...

Assessment of uncontained Zequanox applications in a Midwestern lake data Assessment of uncontained Zequanox applications in a Midwestern lake data

We applied Zequanox using a custom-engineered, boat mounted application system to replicated 0.30 Hectare plots within a small inland lake. The objectives of these applications were to determine if uncontained, open-water Zequanox applications could effectively control zebra mussel populations and protect native unionid mussel populations within zebra mussel infested systems. The...

At-sea movements of Masked Boobies from Pedro Cays, Jamaica, 2012 At-sea movements of Masked Boobies from Pedro Cays, Jamaica, 2012

As part of a larger effort to examine individual-based movement patterns and habitat use at sea for seabirds in the Caribbean, a tracking study of Masked Boobies (Sula dactylatra) breeding on the Pedro Cays, Jamaica, was implemeted in 2012. This population is one of the largest of the few breeding groups in the region. The Masked Booby is considered to be declining and regionally...

At-Sea Ranging Behavior of Seabirds Breeding in the Main Hawaiian Islands: Bio-logger Data Release (ver. 2.0, May 2020) At-Sea Ranging Behavior of Seabirds Breeding in the Main Hawaiian Islands: Bio-logger Data Release (ver. 2.0, May 2020)

Due to recent interest in developing offshore wind energy infrastructure around the main Hawaiian Islands (MHI), U.S. Geological Survey Western Ecological Research Center (USGS-WERC) partnered with the Bureau of Ocean Energy Management (BOEM) from 2013-2016 to study breeding Hawaiian seabird distributions, habitat utilizations, and ranging behaviors within near-island and outer...

Audiomagnetotelluric data, Buffalo River watershed, Arkansas, 2017 Audiomagnetotelluric data, Buffalo River watershed, Arkansas, 2017

This dataset includes the locations for audio-magnetotelluric (AMT) sounding data collected in August 2017 in the Buffalo River watershed of northern Arkansas by the U.S. Geological Survey (USGS). The sites were mostly alongside Osage Creek and its intermittent tributaries. Along with geologic mapping, the USGS used AMT data at 6 sites along a southwest-northeast profile of about 7...

Audiomagnetotelluric survey to characterize the Sunnyside porphyry copper system in the Patagonia Mountains, Arizona Audiomagnetotelluric survey to characterize the Sunnyside porphyry copper system in the Patagonia Mountains, Arizona

This dataset includes audiomagnetotelluric (AMT) sounding data collected in 2008 in and near the Patagonia Mountains of southern Arizona. The U.S. Geological Survey (USGS) conducted a series of multidisciplinary studies as part of the Assessment Techniques for Concealed Mineral Resources project funded by the USGS Minerals Resources Program in cooperation with the U.S. Forest Service...

Autonomous Underwater Vehicle Water-Quality and Sonar Measurements in Delaware River near Philadelphia, Pennsylvania, 2019 Autonomous Underwater Vehicle Water-Quality and Sonar Measurements in Delaware River near Philadelphia, Pennsylvania, 2019

These data sets were created in support of the U.S. Geological Survey's (USGS) Next Generation Water Observing System (NGWOS) for the Delaware River Basin pilot study (Eberts, Wagner, and Woodside, 2019). The NGWOS utilizes real-time data, improved computational capabilities, and new technologies such as the rapid deployment of unmanned aerial vehicle's (UAV) and autonomous underwater...

Avalanche occurrence records along the Going-to-the-Sun Road, Glacier National Park, Montana (ver. 5.0, March 2026) Avalanche occurrence records along the Going-to-the-Sun Road, Glacier National Park, Montana (ver. 5.0, March 2026)

Starting in 2003, the U.S. Geological Survey (USGS) Northern Rocky Mountain Science Center in West Glacier, MT, in collaboration with the National Park Service, collected avalanche observations along the Going to the Sun Road during the spring road-clearing operations. The spring road-clearing along Going to the Sun Road utilized a team of avalanche specialists from the USGS and Glacier...
