Microfocus X-ray computed tomography measurements of ostracode Paracyprideis pseudopunctillata from the Beaufort Sea Microfocus X-ray computed tomography measurements of ostracode Paracyprideis pseudopunctillata from the Beaufort Sea
This dataset includes measurements of shell properties (e.g. density, volume, and weight) of the ostracode species Paracyprideis pseudopunctillata (subphylum Crustacea), which inhabits the continental shelves of the Arctic Ocean. Using microfocus X-ray computed tomography (microXCT) scans, we generated detailed morphometric measurements of specimens collected from both surface and down...
Water withdrawals in Louisiana, 2020 Water withdrawals in Louisiana, 2020
Information concerning the availability, use, and quality of water in the 64 parishes of Louisiana is critical for water-supply management. In cooperation with the Louisiana Department of Transportation and Development, the U.S. Geological Survey (USGS) Lower Mississippi-Gulf (LMG) Water Science Center (WSC) has been collecting, compiling, and publishing water-withdrawal and water-use...
Geologic map database of the Bison Range and vicinity, northwestern Montana Geologic map database of the Bison Range and vicinity, northwestern Montana
This data release provides Geologic Map Schema (GeMS)-compliant GIS data for new geologic mapping of the Bison Range and surrounding area on the Flathead Reservation, northwestern Montana. The database represents the geology for the 150 square kilometer, geologically complex map area, at a publication scale of 1:24,000. The map covers parts of Sanders and Lake Counties, Montana. All...
Hawai‘i Volcanoes National Park, Barcoding of Ambrosia Beetles and Wood-boring Lepidoptera Larva, 2021-2023 Hawai‘i Volcanoes National Park, Barcoding of Ambrosia Beetles and Wood-boring Lepidoptera Larva, 2021-2023
Ambrosia beetles (Coleoptera: Curculionidae) have been implicated in the spread of Ceratocystis fungi that cause rapid ‘ōhiʻa death (ROD), a deadly fungal disease threatening the keystone Hawaiian tree ʻōhiʻa lehua (Metrosideros polymorpha). Research has investigated the role that ambrosia beetles play in the spread of the disease, including studies within Hawaiʻi Volcanoes National Park...
Model Archive Summary for Turbidity Derived Suspended-Sediment Concentration at 14179000 Breitenbush River above French Creek near Detroit, Oregon Model Archive Summary for Turbidity Derived Suspended-Sediment Concentration at 14179000 Breitenbush River above French Creek near Detroit, Oregon
This document describes a new equation for estimating suspended-sediment concentration (SSC) at a fixed point from turbidity values at continuous 15-minute intervals and daily suspended sediment load at USGS site Breitenbush River above French Creek near Detroit, Oregon. The methods described follow USGS guidance as referenced in USGS Techniques and Methods, Book 3, Chap. C2 (Edwards and...
Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada
Northern deltas receive chromophoric dissolved organic matter (CDOM) from their watersheds, which can be oxidized to carbon dioxide upon absorption of sunlight (i.e., photomineralized). These deltas also receive total suspended solids (TSS), which may shade sunlight absorption by CDOM, thus limiting photomineralization. To quantify this interaction for the first time, we measured
