Data

These data were collected to determine the effect of nitrapyrin, a commercial nitrification inhibitor, on nitrification by a diverse nitrifier-enriched microbial (NEM) community. The NEM community was originally collected from an aquaculture pond in Columbia, Missouri and cultured in HEPES-buffered, minimal mineral salts media, supplemented with a nominal dose of 2 milligrams per liter...

Nitrogen (N), phosphorus (P), and suspended sediment (SS) loads in Fairfax County, Virginia streams were calculated using monitoring data from 5 intensively monitored watersheds for the period from water year (October - September) 2008 through 2022. Nutrient (N and P) and SS loads were computed using a surrogate (multiple-linear regression) approach with lab analyzed N, P, and SS samples...

As part of the Interconnected Coastal Environments at Decadal Timescales and Coastal Sediment Availability and Flux projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey to map the shoreface and characterize stratigraphy near Wallops and Assawoman Islands, Virginia (VA). The purpose of this...

A pair of modified marine radars were deployed at two locations, the Clark's Fork Fish Hatchery (near Powell, Wyoming) and the Timber Creek Ranger Station (near Meeteetse, Wyoming), during the summer of 2023 and 2024. The radars collected data on flying animals with a focus on army cutworm (Euxoa auxiliaris) moths within a couple kilometers of the radars during most of the army cutworm...

The majority of landbirds breeding in eastern North America migrate through the Gulf of America (Gulf of Mexico; hereafter Gulf) region during spring and fall. Rarely do migratory landbirds make nonstop flights between breeding and non-breeding areas, rather they stopover in habitats (a.k.a. stopover sites) en route to rest and refuel. Forested habitats in the northern Gulf region...

The Ecology Section at the USGS Conte Laboratory has conducted individual tagging studies in a number of locations. We provide data here for three smaller studies (Sawmill river in MA, USA, Shorey brook in ME, USA, and Catamaran brook in NB, CA). The goal is to understand the strength and direction of drivers on fish growth, movement and survival in the wild. We hope to provide a...

This TX_LowerRioGrande_D22 project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at an aggregate nominal pulse spacing (ANPS) of 0.18 meters (30 ppsm) and 0.35 meters (8ppsm). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification 2022 Rev A. The data was developed based...

Rapid heating events, such as heatwaves, are becoming more frequent and intense as a result of climate change. Importantly, such extreme weather events can be more important drivers of extirpation and selection than changes in annual or seasonal averages and they pose a particularly large threat to poikilothermic organisms. In this study, we evaluate the thermal stress response of a...

This data release contains rasterized data sets of point values of site amplification for the Walnut Creek and Concord regions of the San Francisco east bay. Hartzell et al. (2024) covers the associated field work and the source-site inversion method used to obtain the site response spectra. Site amplification values are given for the geometric average over four frequency ranges (0.5 to...

DeepFaune New England (DFNE) is a model for species classification in trail camera imagery. This model is a re-trained version of the DeepFaune model for classifying European species in trial cameras, fine-tuned to classify taxa from northeastern North America. The DFNE model takes as input cropped images of each animal, which can be generated by an object detection model. DFNE...

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center’s (USGS SPCMSC) Core Archive in St. Petersburg, FL contains a collection of coral-reef cores collected from throughout the Florida Keys reef tract (FKRT; Fig. 1). In a previous study (Toth and Stathakopoulos, 2019), USGS researchers analyzed the upper, Holocene (~11,700 years ago to present) sections of those...

These lidar point clouds and images cover, in high detail, the terrain at Great Sippewissett Marsh, Cape Cod, MA on November 2nd, 2022. USGS researchers tested different sensors that collected lidar and images for photogrammetry point cloud data using Uncrewed Aerial Systems (UAS) to look at differences in coverage and elevation accuracy. The lidar data were acquired with a YellowScan...
