Detections of marine fauna using environmental DNA metabarcoding of seawater samples from the northern Gulf of America Detections of marine fauna using environmental DNA metabarcoding of seawater samples from the northern Gulf of America
We sampled seawater from nine mesophotic reef sites in the Pinnacles Trend and DeSoto Rim areas in the northern Gulf of America in October 2022 to complement and inform restoration investments for coral communities. Four primer sets were used to amplify environmental DNA (eDNA) from seawater, targeting metazoans, eukaryotic plankton and protists, corals, and fishes. Across all markers...
Determination of the concentration and activity of microcystin-LR and degradants after irradiation with 254 nm and 222 nm UV light with Protein phosphatase 2a inhibition assays and high-resolution mass spectrometry using isotope dilution Determination of the concentration and activity of microcystin-LR and degradants after irradiation with 254 nm and 222 nm UV light with Protein phosphatase 2a inhibition assays and high-resolution mass spectrometry using isotope dilution
Microcystin-LR (MC-LR), a cyanotoxin produced during some harmful algal blooms (HABs), can have negative impacts on water ecosystems. Current treatment methods have potential drawbacks: physical removal can cause cell lysis and toxin release, and chemical treatment can cause disinfection byproducts (DBPs). Ultraviolet C (UV-C) treatment can degrade cyanotoxins without producing...
Detrital zircon U-Pb data for paleontological localities in the Piceance Creek Basin Detrital zircon U-Pb data for paleontological localities in the Piceance Creek Basin
This data release hosts detrital zircon U-Th-Pb geochronology data that were created to support geologic mapping and research in the context of the Geologic Framework of the Intermountain West Project supported by the National Cooperative Geologic Mapping Program. These data characterize the deposition age and provenance of Cretaceous stratigraphic units exposed in the Piceance Creek...
Detrital zircon U-Pb data for reconnaissance characterization of strata across the Intermountain West region of the United States Detrital zircon U-Pb data for reconnaissance characterization of strata across the Intermountain West region of the United States
This document describes sedimentary rock samples and their associated detrital zircon U-Pb data that were collected to support geologic mapping and research initiatives within the context of the Geologic Framework of the Intermountain West Project. The data characterize the age and/or provenance of Neoproterozoic to Miocene strata exposed across the Intermountain West region of the...
Developing a land change monitoring capability and supporting training data strategy for select international sites: First Outputs Developing a land change monitoring capability and supporting training data strategy for select international sites: First Outputs
The monitoring of landscape change is widely recognized as an important component towards understanding how the Earth changes and the impacts of, and to, human societies. The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center has been developing a monitoring capability suitable for monitoring land change along with climate-related factors towards the long...
Developing an annual land surface temperature from 1985 to present for select international sites: First Outputs Developing an annual land surface temperature from 1985 to present for select international sites: First Outputs
Surface Urban Heat Island (SUHI) land surface temperature (LST) data is derived from Landsat thermal band. The LST including annual mean LST (MeanLST) and annual maximum LST (AVEMaxLST). The annual mean LST (MeanLST) therefore represents the average of all clear observations in a specific year. The seasonal maximum temperatures were then averaged to represent the annual mean maximum LST...
Development and efficiency of less intrusive survey methodologies for Santa Ana sucker (Pantosteus santaanae) monitoring Development and efficiency of less intrusive survey methodologies for Santa Ana sucker (Pantosteus santaanae) monitoring
The Santa Ana Sucker (Pantosteus santaanae) is a federally threatened species endemic to the Santa Ana, San Gabriel, and Los Angeles Rivers in southern California. Seasonal limitations on conventional sampling and inconsistencies in survey methodologies have led to an incomplete understanding of Santa Ana Sucker population dynamics. Therefore, alternative sampling methods that are not...
Development and optimization of species-specific qPCR assays for eDNA detection of the mucket (Ortamannia ligamentina) and spectaclecase (Cumberlandia monodonta) mussels’ male mitotype Development and optimization of species-specific qPCR assays for eDNA detection of the mucket (Ortamannia ligamentina) and spectaclecase (Cumberlandia monodonta) mussels’ male mitotype
This dataset describes the sensitivity (limit of detection and limit of quantification) and specificity (list of species tested against the assays) of two qPCR assays designed to detect the male mitotype of two freshwater mussel species Ortmanniana ligamentina and Cumberlandia monodonta from water samples (eDNA).

These datasets contain the carbon and nitrogen stable isotope data from diamondback terrapin epidermis tissue and a variety of sampled prey items.
Diatom Samples from Ocean Drilling Program Leg 112, Holes 682A and 688E from Offshore Peru Diatom Samples from Ocean Drilling Program Leg 112, Holes 682A and 688E from Offshore Peru
The diatom biochronology of ODP Holes 682A and 688E provides a nearly complete offshore reference section to correspond with onshore studies of the Miocene age materials of the East Pisco Basin of Southern Peru, which is known for its excellent preservation of fossil vertebrates. From these holes a nearly complete sequence of low latitude and northeastern Pacific diatoms has been...
Diet Data from Fecal DNA Metabarcoding and Video Camera Collars from the Porcupine Caribou Herd, Alaska and Yukon Diet Data from Fecal DNA Metabarcoding and Video Camera Collars from the Porcupine Caribou Herd, Alaska and Yukon
These diet data were collected from the Porcupine caribou herd in northern Alaska and Yukon in summer 2021 during 4 periods: calving (occasion 1), post-calving (occasion 2), mosquito harassment (occasion 3), and mid-summer (occasion 4). Diet data was determined by two distinct techniques: DNA metabarcoding data from fecal pellets and video data from camera collars deployed on adult...
Diet, morphometric and demographic data for cisco (Coregonus artedi) collected in the winter and spring of 2022-2023 in Lake Michigan and connected waters Diet, morphometric and demographic data for cisco (Coregonus artedi) collected in the winter and spring of 2022-2023 in Lake Michigan and connected waters
These data describe demographic, diet contents and associated weights, fullness index, morphometrics (body shape), and meristic (total number of gill rakers) measurements of cisco (Coregonus artedi) collected in Lake Michigan along the eastern shoreline, the Pine River/ Lake Charlevoix Channel, and from three drowned river mouth lakes (Portage Lake, Muskegon Lake, Lake Charlevoix) from...
