Data for Assessing the Utility of eDNA Approaches for Determining the Impacts of Metal Mobilization from Thawing Permafrost on Fish Communities in Arctic Streams Data for Assessing the Utility of eDNA Approaches for Determining the Impacts of Metal Mobilization from Thawing Permafrost on Fish Communities in Arctic Streams
This data set describes results for laboratory experiments to determine the efficacy of environmental DNA quantitative PCR assays for four fish species when applied to filtered water samples containing metals mobilized from thawing permafrost.
Macoma Clam Prey Identified by DNA Metabarcoding, 2018 and 2019, Alaska Macoma Clam Prey Identified by DNA Metabarcoding, 2018 and 2019, Alaska
This dataset describes sequence data derived from 18S ribosomal and ribulose bisphosphate carboxylase (rbcL) DNA. Stomach contents from 190 Macoma calcarea clams were examined for this study. Clams were collected from the Bering Sea and Chukchi Sea, Alaska in 2018 and 2019 using benthic van Veen grabs.
Geophysical and video logs of four wells from the Mountain Home area, Idaho Geophysical and video logs of four wells from the Mountain Home area, Idaho
In cooperation with the Idaho Department of Water Resources, the U.S. Geological Survey (USGS) collected groundwater levels, geophysical logs, and video logs at four newly constructed monitoring wells from the Mountain Home area, Idaho, between November 12 and November 14, 2024. The Mountain Home area is located in the western Snake River plain, 40 miles to the southeast from the state...
Digital Data of Structural Contours from Previously Published USGS Mississippi Embayment Studies Digital Data of Structural Contours from Previously Published USGS Mississippi Embayment Studies
This digital dataset is a result from the goal within the U.S. Geological Survey’s (USGS) National Cooperative Geologic Mapping Program to convert surficial data that were previously published in non-digital format to digital, vector-based data suitable for use by the public and in USGS studies. The objective of the data conversion is to reproduce the original published mapping with...
Estimates of population exposure and evacuation potential for earthquake-related tsunami hazard zones in the United States Estimates of population exposure and evacuation potential for earthquake-related tsunami hazard zones in the United States
These datasets support the conclusions in the journal article entitled "National population exposure and evacuation potential in the United States to earthquake-generated tsunami threats " as described in the abstract below: Previous efforts to characterize tsunami threats to people have focused primarily on individual scenarios in specific areas but have not recognized multiple...
Pedestrian evacuation time maps for the Commonwealth of the Northern Mariana Islands tsunami-hazard zones Pedestrian evacuation time maps for the Commonwealth of the Northern Mariana Islands tsunami-hazard zones
The communities of the Commonwealth of the Northern Mariana Islands are threatened by tsunamis. Experts conducted earthquake and tsunami modeling to estimate the extent of tsunami inundation resulting from a Mariana Subduction Zone (MSZ) earthquake. The USGS Pedestrian Evacuation Analyst Tool (PEAT) was run to estimate pedestrian evacuation travel times out of the MSZ tsunami-hazard zone...
