This project is a collection of Bald Eagle nesting surveys conducted in various locations throughout Alaska. Surveys were conducted using a variety of platforms, including fixed wing and rotor-wing aircraft, boats, and foot surveys. Survey effort ranges from a one-time location of a nest in an area with no previous information, to nest occupancy and productivity survey conducted in one year, to repeated occupancy and productivity surveys over multiple years. Data was collected on nest occupancy (including presence and behavior of eagles used to determine the nest status; i.e., active or occupied, inactive or unoccupied, empty, or unknown), nest success and productivity (including if nestlings reached ~80% of fledging...

This dataset contains Sanger ITS sequences from biocrust lichen taxa collected at Horse Heaven Hills in Washington, USA. It also includes metagenomic biocrust lichen data from 20 plots at Horse Heaven Hills in Washington, USA. These data were collected by Bruce McCune and Heather Root in 2019-2020 and sequenced for ITS using bulk sequencing in the PacBio system at Brigham Young University by Steve Leavitt.
The Thera cluster is named for the volcanic island Thera (also known as Santorini), the southernmost member of the Cyclades island group in the Aegean Sea. The cluster is dominated by an earthquake sequence that began in early February, 2025, 20-40 km northeast of Thera. The sequence has swarmlike characteristics but it is, as yet, unclear if the activity is volcanic or tectonic in nature. The cluster includes the 7.7 Mw tsunamigenic earthquake of July 9, 1956 and 3 of its aftershocks. The mainshock is located ~10 km southeast of the southern end of the ongoing 2025 swarm, midway between the southern end of the Santorini-Amorgos Fault and the Anafi-Astypalaea Fault (Leclerc, F., Palagonia, S., Feuillet, N. et al....

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This map layer shows areal and linear water features of Florida, Georgia, South Carolina, and Alabama. The original file was produced by joining the individual State hydrography layers from the 1:2,000,000- scale...

Data presented are results of surveys in 2021 for Southwestern Willow Flycatcher (Empidonax traillii extimus) in San Diego County, California. Surveys were conducted at the 2016-19 nest monitoring locations (Cleveland National Forest, Rey River Ranch, and Vista Irrigation District) and at Lake Henshaw along the Upper San Luis Rey River. Surveys were conducted along multiple sections of the river where permission to access properties could be obtained. Locations were surveyed using a standardized protocol three to four times between 15 May and 31 July. The number, age (adult or juvenile), sex, banding status (color banded or not, and if so, color combination), and breeding status (paired, undetermined, or transient)...

This metadata is part of a larger Mark-Release-Recapture (MRR) study of adult Culex quinquefasciatus conducted in a montane rainforest in Upper Waiākea Forest Reserve on the Island of Hawai'i. The dataset consists of a list of all Culex quinquefasciatus captured during the Recapture phase of the trial, following two consecutive releases of marked mosquitoes. Cohorts of both wild captured mosquitoes marked with fluorescent pigments and lab-reared, rhodamine B marked mosquitoes were released together on the evening of November 16, 2020 but only lab-reared rhodamine B marked mosquitoes were released on the evening of November 21, 2020. We scored the degree of fluorescence from 0 to 3 using the wild caught mosquitoes...
We compared pollinator diversity derived from environmental DNA (eDNA) extracted from flowers and DNA extracted from pulverized bulk samples of insects collected from vane traps deployed at the same sites. We used three metabarcoding primers, two of which target arthropods generally (COI-Jusino and 16S-Marquina) and one that targets bumblebees (Bombus spp., COI-Milam). Across methods, we detected 77 insect families from 9 orders. The COI-Jusino marker amplified the highest taxonomic diversity compared to 16S-Marquina and COI-Milam. More ASVs were recovered from vane traps (blue: 1357, yellow: 1542) than flowers (245), but only 23% of families and 13% of genera were shared among methods, indicating that flowers and...
This dataset includes a collection of files related to a project investigating the ecology of six lakes in the Tokopah Basin. The primary purpose of the research project was to understand the dynamics of periphyton growth and the potential relationships with nitrogen and copper concentrations in high elevation lakes of the Sierra Nevada mountains in Sequoia National Park, California. Additional research questions included those related to ecological variation between different lakes within the same basin, and those related to potential ecotoxicity of copper to organisms in these ecosystems. Files in this release contain data of lake depth profiles, lake watershed characteristics, Secchi depth, time series of specific...
This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water-leaving radiance (units of watts per square meter per steradian per nanometer) to downwelling irradiance (units of watts per square meter per nanometer) multiplied by π. This is also known as remote sensing reflectance (units of per steradian) multiplied by π. These data are intended for use in remote sensing of water color and differ...
This project is a collection of Peregrine Falcon (Falco peregrinus) location data obtained with GPS satellite tags. Information includes bird identity, geographic coordinates (latitude and longitude in WGS84 Datum), elevation, and various other bits of information regarding tag function. Data are used to understand Peregrine Falcon home range size and shape and migration and movement during different seasons and years, as well as Peregrine Falcon survival. These data provide important information about Peregrine Falcon space use and survival that could not be obtained without marked birds.

U. S. Geological Survey (USGS) scientists completed a stream survey campaign from the 26th of July to the 13th of August in 2021 at thirty 100-meter reaches within the Shenandoah Valley throughout Virginia and West Virginia. In each stream reach, the following survey measurements were made or attempted: three representative channel cross sections, water surface elevation at the top and bottom of each reach, and longitudinal thalweg point data. The survey data will be used with additional geomorphological measurements and habitat information to assess habitat quality of these Shenandoah Valley streams. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the...
