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
Digital database of previously published subsurface unit tops from the three-dimensional geologic model used for the 2003 National Oil and Gas Assessment of the San Joaquin Basin Province, California Digital database of previously published subsurface unit tops from the three-dimensional geologic model used for the 2003 National Oil and Gas Assessment of the San Joaquin Basin Province, California
This data release provides digital geospatial data related to the three-dimensional geologic model (Hosford Scheirer, 2013) that was used as a framework for conducting the 2003 oil and gas assessment of the San Joaquin Basin province, California (Gautier and others, 2004; Hosford Scheirer, ed., 2007). The data release includes raster GeoTIFF files of the tops of the 15 composite geologic...
Soil-Water-Balance (SWB) Model Archive Used to Simulate Potential Recharge with Projections for Future Climate Scenarios, Saco River Basin, Maine and New Hampshire Soil-Water-Balance (SWB) Model Archive Used to Simulate Potential Recharge with Projections for Future Climate Scenarios, Saco River Basin, Maine and New Hampshire
This model archive makes available the Soil-Water-Balance (SWB) model used to simulate potential recharge for the Saco Headwaters Watershed. This model was used to simulate potential recharge (net infiltration) for use in a groundwater model in the same region to understand the effects of water bottling. The model was used to produce a historical simulation (2000 -2021) and a series of...
