Digital orthophotos and field measurements of flow velocity from the Tanana and Nenana Rivers, Alaska, from August 2021 (ver. 2.0, June 2024) Digital orthophotos and field measurements of flow velocity from the Tanana and Nenana Rivers, Alaska, from August 2021 (ver. 2.0, June 2024)
This data release includes digital orthophotos acquired from a fixed-wing aircraft and field measurements of flow velocity from the Tanana and Nenana Rivers near Nenana, Alaska, obtained on August 18 and 19, 2021. This parent data release includes links to child pages for two data sets produced during the study: 1. Acoustic Doppler Current Profiler (ADCP) field measurements of flow...
Developmental stage and length of Pallid Sturgeon and Shovelnose Sturgeon free embryos reared at a constant temperature Developmental stage and length of Pallid Sturgeon and Shovelnose Sturgeon free embryos reared at a constant temperature
This dataset documents the length and developmental stage of pallid sturgeon and shovelnose sturgeon free embryos from the time of hatch through melanin plug expulsion (the approximate onset of exogenous feeding) reared in the laboratory at a constant temperature. Free embryos from 4 pallid sturgeon crosses and 7 shovelnose sturgeon crosses were reared separately in the laboratory at a...
Predicting climate change impacts on poikilotherms Predicting climate change impacts on poikilotherms
This software involves files to fit the physiologically-guided abundance (PGA) model ('fish_predictions_pga.R'), a naive model ('fish_predictions_naive.R'), and a PGA model using simulated data ('PGA_sim.R'). Each R file calls as associated .stan file that contains the model code that is executed by stan when running the R code ('fish_prediction.stan', 'fish_prediction_naive.stan', and...
Basin Characteristics Data for the StreamStats Application in the Mystic River Basin, Massachusetts Basin Characteristics Data for the StreamStats Application in the Mystic River Basin, Massachusetts
The U.S. Geological Survey’s StreamStats program is a publicly-accessible web application (https://streamstats.usgs.gov) that can be used to delineate drainage areas, compute basin characteristics, and estimate flow statistics for user-selected locations on streams. StreamStats services are typically implemented at the statewide or watershed scale (referred to as state or basin...

SUTRA model used to evaluate long-term groundwater availability in the Waihee, Iao, and Waikapu aquifer systems, Maui, Hawaii SUTRA model used to evaluate long-term groundwater availability in the Waihee, Iao, and Waikapu aquifer systems, Maui, Hawaii
Groundwater levels have declined since the 1940s in the Wailuku area of central Maui, Hawaii, on the eastern flank of West Maui volcano, mainly in response to increased groundwater withdrawals. Available data since the 1980s also indicate a thinning of the freshwater lens and an increase in chloride concentrations of pumped water from production wells. These trends, combined with...
