Status and trends of adult Lost River (Deltistes luxatus) and shortnose (Chasmistes brevirostris) sucker populations in Upper Klamath Lake, Oregon, 2023 Status and trends of adult Lost River (Deltistes luxatus) and shortnose (Chasmistes brevirostris) sucker populations in Upper Klamath Lake, Oregon, 2023
Data were collected as part of a long-term capture-recapture program to assess the population dynamics of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning...
Eutrophication and plankton communities (Cyanobacteria and eukaryotic algae) in the Grand Calumet River Area of Concern, Indiana, 2021 Eutrophication and plankton communities (Cyanobacteria and eukaryotic algae) in the Grand Calumet River Area of Concern, Indiana, 2021
The data being released were part of a project funded by the United States Environmental Protection Agency (USEPA). This study sought to identify the planktonic communities (cyanobacteria, eukaryotic algae) potentially contributing to eutrophication within the Grand Calumet River Area of Concern (AOC) in northern Indiana along the southern shore of Lake Michigan. In 2021, triplicate...
Pedestrian evacuation time maps, flow depth time series, and population estimates for the island of Guam tsunami evacuation zone Pedestrian evacuation time maps, flow depth time series, and population estimates for the island of Guam tsunami evacuation zone
These datasets support the conclusions in the journal article entitled "Modeling non-structural strategies to reduce pedestrian evacuation times for mitigating local tsunami threats in Guam" as described in the abstract below: Reducing the potential for loss of life from local tsunamis is challenging for emergency managers given the need for self-protective behavior within brief windows...
Data from Decadal Change in Groundwater Quality Web Site, 1988-2022 Data from Decadal Change in Groundwater Quality Web Site, 1988-2022
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...
Model Archive Summary for acoustic derived suspended-sediment concentration at 13269000 Snake River at Weiser, ID Model Archive Summary for acoustic derived suspended-sediment concentration at 13269000 Snake River at Weiser, ID
Model archive summary describing the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Snake River at Weiser, ID – USGS site ID# 13269000. The model can be used to develop a time series of suspended sediment concentration based on acoustic backscatter and...
Radiocarbon dates from the 2020 Bobcat Fire and 2013 Grand Fire, Western Transverse Ranges, California Radiocarbon dates from the 2020 Bobcat Fire and 2013 Grand Fire, Western Transverse Ranges, California
This data release provides radiocarbon data for burned plant material collected from deposits following two wildfires in southern California. For the 2020 Bobcat Fire we collected deposits in five stream channels within the Pallett Creek drainage in 2021. For the 2013 Grand Fire near Frazier Mountain, we sampled from two shallow pits excavated into alluvium deposited in 2014. The types...
