Reach-scale estimates of nutrient, water use, dissolved oxygen, and pH conditions in the Pacific drainages of the United States Reach-scale estimates of nutrient, water use, dissolved oxygen, and pH conditions in the Pacific drainages of the United States
This data release contains data sets that describe reach-scale water-quality conditions for the Pacific drainages of the United States. The nutrient and water use conditions represent the predictions from recent USGS SPARROW (Spatially Related Regression on Watershed Attributes) modeling as well as other watershed attributes. The SPARROW predictions and other watershed attributes were...
Data used to determine acceptance criteria for the Petroleum Geochemistry Research Laboratory Programmed Pyrolysis Method Data used to determine acceptance criteria for the Petroleum Geochemistry Research Laboratory Programmed Pyrolysis Method
The data release contains programmed pyrolysis data generated in the Petroleum Geochemistry Research Laboratory that was used to determine the precision and accuracy of daily operating standards for the Petroleum Geochemistry Research Laboratory Programmed Pyrolysis Method.
Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Lone Tree Point, Kiket Bay, WA, June 2019 Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Lone Tree Point, Kiket Bay, WA, June 2019
An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at Lone Tree Point, Kiket Bay, Washington on June 5, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive a high-resolution digital surface model (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of...

Community metrics from inter-agency compilation of inland fish sampling data within the Chesapeake Bay Watershed Community metrics from inter-agency compilation of inland fish sampling data within the Chesapeake Bay Watershed
This data release contains calculated metrics which summarize various biodiversity and functional/life history trait information about fish communities sampled across the Chesapeake Bay Watershed as well as ancillary data related to time/place of sampling and sampling methodology. The fish sampling data used to compute these metrics were compiled from various fish sampling programs...
CTD profiles and discrete water-column measurements collected off California and Oregon during NOAA cruise SH-18-12 (USGS field activity 2018-663-FA) from October to November 2018 (ver. 2.0, September 2021) CTD profiles and discrete water-column measurements collected off California and Oregon during NOAA cruise SH-18-12 (USGS field activity 2018-663-FA) from October to November 2018 (ver. 2.0, September 2021)
Various water column variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, dissolved inorganic carbon, radio-carbon isotopes were measured in samples collected using a Niskin-bottle rosette at selected depths from sites offshore of California and Oregon from October to November 2018 during NOAA cruise SH-18-12 on the R/V Bell M. Shimada (USGS field activity...
