Database for the preliminary bedrock geologic map of the Port Henry quadrangle, Essex County, New York, and Addison County, Vermont Database for the preliminary bedrock geologic map of the Port Henry quadrangle, Essex County, New York, and Addison County, Vermont
The preliminary bedrock geologic map database of the 7.5-minute Port Henry quadrangle consists of deformed and metamorphosed Mesoproterozoic gneisses of the Adirondack Highlands unconformably overlain by weakly deformed lower Paleozoic sedimentary rocks of the Champlain Valley (fig. 1) on the published geologic map. The Mesoproterozoic rocks occur on the eastern edge of the Adirondack...
Environmental DNA and Fish Capture Data from Round Goby Surveys on the Schoharie Creek, New York Environmental DNA and Fish Capture Data from Round Goby Surveys on the Schoharie Creek, New York
This data release contains site location information, environmental DNA (eDNA) data, and fish capture data from round goby (Neogobius melanostomus) surveys conducted on parts of the Schoharie Creek, New York, during 2024 and 2025. Data were collected in two phases. During Phase 1 (March–July 2024), a rapid assessment of the round goby invasion front (furthest upstream extent of the...
Island Night Lizard monitoring data on San Nicolas Island, CA, 1995-2023 Island Night Lizard monitoring data on San Nicolas Island, CA, 1995-2023
These data were compiled for the U.S. Navy and U.S. Fish and Wildlife Service and consist of summary counts at selected population monitoring sites for the Island Night Lizard (Xantusia riversiana), and measurement data (body length, mass) for calculating an index of body condition. Objectives of this study were to provide long-term population trend and health and condition data to the U...
Model archive for suspended sediment regression models in rloadest to estimate suspended sediment concentration and loads for the Snake River at Weiser, Idaho, 1977-2022 Model archive for suspended sediment regression models in rloadest to estimate suspended sediment concentration and loads for the Snake River at Weiser, Idaho, 1977-2022
Regression models for estimating suspended sediment concentration (SSC) and loads were developed using the R package rloadest for U.S. Geological Survey streamgage Snake River at Weiser, Idaho (13269000). Samples for suspended sediment concentration were collected in two periods: the historical (1977-2003) and modern (2017-22) periods. Data and metadata for all samples collected at this...
Qualitative Analysis of Cyanotoxins in Lake Erie Samples Using Liquid Chromatography/High Resolution Mass Spectrometry (LC/HRMS) from July 2016 to October 2022 Qualitative Analysis of Cyanotoxins in Lake Erie Samples Using Liquid Chromatography/High Resolution Mass Spectrometry (LC/HRMS) from July 2016 to October 2022
Toxic harmful algal blooms are caused by cyanobacteria and can pose a threat to freshwater ecosystems, including the western basin of Lake Erie. Bloom toxicity can be influenced by variation of biosynthetic repertoires of toxic cyanobacteria but is not well studied beyond microcystins. Water samples collected by the National Oceanic and Atmospheric Administration from July 2016 through...
Radiocarbon, U-series, and amino acid chronology data for late Quaternary marine terraces in coastal Santa Barbara County, California, USA Radiocarbon, U-series, and amino acid chronology data for late Quaternary marine terraces in coastal Santa Barbara County, California, USA
In several early studies, central California marine terraces between Santa Barbara and Point Conception were interpreted to record sea-level high stands of the last interglacial complex, ~80 ka to ~120 ka (marine isotope stage [MIS] 5). These ages and their elevations (~20 m to ~45 m) indicate modest rates of tectonic uplift, similar to those from other localities in southern and central
