Inset models used to evaluate the effects of layering configuration on model calibration from 1900 to 2018, and assess managed aquifer recharge near Shellmound, Mississippi, from 2019 to 2050 Inset models used to evaluate the effects of layering configuration on model calibration from 1900 to 2018, and assess managed aquifer recharge near Shellmound, Mississippi, from 2019 to 2050
The U.S. Geological Survey (USGS), in cooperation with the Mississippi Department of Environmental Quality (MDEQ), have developed a high-resolution inset groundwater flow model for the Mississippi River delta as part of an interdisciplinary collaboration, coordinated by the Mississippi Alluvial Plain (MAP) project to provide a tool that stakeholders can use to support water resources...
Bathymetry and acoustic-backscatter data for Lake Sammamish, Washington collected during USGS field activity 2021-656-FA Bathymetry and acoustic-backscatter data for Lake Sammamish, Washington collected during USGS field activity 2021-656-FA
The Pacific Northwest is home to numerous faults that cut through the surrounding crust including the Seattle fault. Over time, frictional stresses accumulate along these faults, building slowly until they exceed the fault's strength, resulting in an earthquake. Evidence of these earthquakes may be found in Pacific Northwest lakes. Past underwater landslides caused by the earthquakes...
Land carbon sink in the conterminous US from 1985 to 2020 Land carbon sink in the conterminous US from 1985 to 2020
This carbon dataset is generated from the parallel Integrated Biosphere Simulator (pIBIS). Annual carbon variables cover 1985-2020 at 1-km (990m) spatial resolution. All the variables are in NetCDF format. Each variable has 36 layers, 2960 rows, 4677 columns, and in WGS_1984_Albers projection. A single layer mask file TIF is provided. Carbon stock and flux units are in kgC/m2 and kgC/m2...
In-situ artificial light at night measurements and planktivore depth distribution in Lake Washington, WA, Summer 2024 In-situ artificial light at night measurements and planktivore depth distribution in Lake Washington, WA, Summer 2024
This dataset includes downwelling irradiance data collected at night on the water's surface and daytime attenuation through the water column. Spectrally specific irradiance values were collected with a Biospherical Instruments Compact-Optical Profiling System (C-OPS) device to measure artificial light at night (ALAN) in Lake Washington, WA. This dataset consists of ALAN surface...
Juvenile Chinook Salmon Outmigration JSATS Telemetry Tagging and Detections in the Klamath River (ver. 2.0, January 2026) Juvenile Chinook Salmon Outmigration JSATS Telemetry Tagging and Detections in the Klamath River (ver. 2.0, January 2026)
We conducted a study to assess the timing of outmigration and survival of juvenile Chinook salmon in relation to managed water flows in the Klamath River. Juvenile salmon were implanted with acoustic telemetry transmitters, and their movements were tracked using remote receivers deployed throughout the lower Klamath River, from Iron Gate Dam to the river’s mouth. Because transmitter...
PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2025 (ver. 6.0, September 2025) PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2025 (ver. 6.0, September 2025)
Note: this data release has been superseded by version 7.0, available here: https://doi.org/10.5066/P14NTJSJ Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus)...
