Responses of Native Freshwater Mussels to Remedial Dredging in the upper Hudson River Responses of Native Freshwater Mussels to Remedial Dredging in the upper Hudson River
The Hudson River, New York, was contaminated with polychlorinated biphenyls (PCBs) from two General Electric plants over a period of ~30 years and PCBs are still present in sediment and biota today. The river provides habitat for a variety of plants and animals, including native freshwater mussels. Although little is known about mussels in this river, managers were concerned that a 7...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional oil and gas resources in the Smackover formation in the U.S. Gulf Coast. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context...
Topographic and multispectral reflectance products, aerial imagery, ground spectra, vegetation, and associated GPS data collected during uncrewed aircraft system operations - Dog Head Marsh at South Cape Beach, Mashpee, MA, October 7-8, 2021 Topographic and multispectral reflectance products, aerial imagery, ground spectra, vegetation, and associated GPS data collected during uncrewed aircraft system operations - Dog Head Marsh at South Cape Beach, Mashpee, MA, October 7-8, 2021
The purpose of this field data collection was to test and compare the OceanInsight HDX Mini Spectrometer as an accessible alternative against the more expensive ASD Fieldspec for collecting ground-based hyperspectral reflectance profiles for landcover analysis. The data collection took place in Dog Head Marsh and South Cape Beach within the Waquoit Bay National Estuarine Research Reserve...

Samoan swallowtail butterfly reproductive life history and parasitism, 2013-2014 Samoan swallowtail butterfly reproductive life history and parasitism, 2013-2014
This data release includes metadata and tabular data documenting the reproductive demography of the Samoan swallowtail butterfly (Papilio godeffroyi), including rates of parasitism by two species of Ooencyrtus wasp. Data was collected at approximately monthly surveys of marked host trees (Micromelum minutum) at eight forest stands, mostly in or adjacent to the National Park of American...
Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2022 Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2022
Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2022 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications...
