This dataset includes CSV data files containing environmental data that may be associated with the occurrence and toxicity of the diatom Pseudo nitzschia in Frenchman Bay, Maine, that can form harmful algal blooms and produce the toxin domoic acid. The dataset covers the period 2010 through 2022 or shorter period depending on the variable. Elevated concentrations of domoic acid in Pseudo...

Geochemical data were obtained to investigate the fate and transport of nitrogen in a subterranean estuary near East Falmouth, Massachusetts. The goal of this investigation was to assess nitrogen attenuation in the aquifer under the Eel River estuary and the adjacent peninsula, introduced as inorganic nitrogen that was densely populated with residences havingfrom residential septic...

This data release consists of one table of multi-year observations of Rock Sandpipers (Calidris ptilocnemis) and aerial photographs of Rock Sandpiper flocks at sites in upper Cook Inlet, Alaska, 1997-2014.

Product Description: This dataset provides maps of peak biomass carbon stock (C) in gC/m2 and net primary productivity (NPP) in gC/m2/yr of coastal herbaceous wetlands at a resolution of 30 m across the conterminous United States (CONUS) for 2015. Aboveground, belowground, and total peak biomass C and NPP are provided for tidal herbaceous wetlands. Data is presented for 1. all herbaceous...

These data pertain to bird point surveys collected from 30 April 2016 to 12 May 2016 and 23 May 2016 to 25 June 2016 at four bottomland hardwood restoration sites in northeastern Indiana. The data are a single monitoring occasion with the purpose of documenting bird communities across these sites. During the time of collection, sites contained areas of hardwood planting ranging in age...

This data set includes images from Dwarf Cypress located within Big Cypress National Preserve. Images were taken multiple times daily from February 2021 to June 2024 using a five-band multispectral camera equipped for normalized difference vegetation index (NDVI) sensing and standard high-quality photographs.

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines (England and others, 2019). The methods are used to provide estimates of peak-flow quantiles for 66.7-, 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance

A tabular dataset providing tick survey results around the Jackson Wyoming area between the dates of Oct 25, 2021, and Nov 6, 2021. The data compares a dog surveyor to a human surveyor in both transect and survey plots, recording detection events, total number of tick larvae found, and how long the survey took, and the cost of the survey. A second tabular dataset outlining the associated...

This data release includes raw detrital zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA. Detrital zircon U-Pb data for five samples of metasedimentary rock (totaling 1459 zircon U-Pb dates) were acquired via laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) at the University of Arizona LaserChron Center. The...

Ferromanganese crust and phosphorite minerals were collected using remotely operated vehicles in the Southern California Borderland during two separate research cruises – NOAA Ocean Exploration Trust cruise NA124 onboard the E/V Nautilus in 2020, and Schmidt Ocean Institute cruise FK210726 onboard the R/V Falkor in 2021. Ferromanganese crust and phosphorite samples were described and...

This Data Release contains supporting data to evaluate fine sediment infiltration into gravels in identified locations of Chinook spawning habitat at three sites on the Sauk River, located in western Washington. Fine sediment infiltration into the river substrate that salmonid fish species use to spawn has been shown to increase mortality during the incubation and pre-emergence phase...

Effective waterfowl management relies on the collection of relevant demographic data to inform land management decisions; however, some types of data are difficult to obtain. For waterfowl, brood surveys are difficult to conduct because wetland habitats often obscure ducklings from being visually assessed. Here, we used Unoccupied Aerial Systems (UAS) to assess what wetland habitat...
