The 14 January 2022 eruption of Tonga Hunga-Tonga Ha'apai volcano generated tsunamis that impacted the west coast of the United States on the morning of 15 January 2022. This data release presents runup heights and tsunami heights collected by the U.S. Geological Survey (USGS) and the California Geological Survey (CGS) during surveys at the Santa Cruz Harbor and beaches in Santa Cruz...

This metadata record contains 6 tables used to assess sources of Polychlorinated Biphenyls (PCB) in the Back River watershed, Baltimore City, Maryland. Included in the dataset are PCB concentrations of surface water and porewater passive samplers from Herring Run, Moores Run, tidal Back River, and Back River Wastewater Treatment Plant; PCB concentrations of bed sediments and other solids...

Anomaly lists are presented documenting operational interference to electricity power grids and communication networks in the United States and Canada during magnetic storms. Four of the anomaly lists apply for magnetic storms that occurred in March 1989, August 1972, March 1940, and for various storms 1946-2000; yet another list consists of statistical values summarizing geomagnetically...

Discrete volumetric and mid-section stream discharge measurements were conducted from July through October 2020 in H.J. Andrews Experimental Forest near Blue River, OR. The measured streams are part of the Lookout Creek basin, draining into Blue River and subsequently the McKenzie River on the west slope of the Cascade Range. ORWSC Streamflow measurements supplemented an eco-drought low...

This data release contains two related datasets acquired for the uncrewed aerial system aeromagnetic test survey at the Boulder Magnetic Observatory. The first contains the raw magnetic data for the set of four test flights, and the second contains the compensated magnetic data for the same four flights. Details of the data are recorded in the metadata files associated with each dataset.

This dataset contains point raw glaciological field data. Snow pit and snow core data give detailed information on snow density through the measured snow column. Snow depth measurements are collected via snow probe and in some snow pits or snow cores that extend the full depth of the snowpack to the glacier's surface. Ablation stakes allow point measurement of both snow depth and snow...

This dataset contains tracking durations for several species of sea turtles tagged with satellite tags between 2008 and 2019. It contains information on species, turtle size, capture methods, tag type, how many days each tag transmitted, whether or not the tag was still attached upon recapture, fouling 'status' of the tag, and foraging region. This dataset thus allows estimation of...

A study to develop an earth observation monitoring system to detect harmful algal bloom (HABs) presence within selected north Texas reservoirs using satellite imagery was conducted by the U.S. Geological Survey (USGS). This data release provides the data collected for this study including site locations, water-quality, phytoplankton, and hyperspectral water surface reflectance data. Data...

Statewide maps of the probability of exceeding a given concentration of either uranium (U) or radon (Rn) in New Hampshire groundwater (represented as statewide rasters) are the product of statistical analyses and are available here. The dependent variables in these statistical models were either 1) the natural log of Rn concentrations or 2) a dichotomous variable indicating the...

This data set is composed of all animals received as a diagnostic submission to the USGS National Wildlife Health Center for which algal toxin testing was performed from November 1998 to January 2018. Birds with a histologic diagnosis of avian vacuolar myelinopathy, a disease caused by the algal toxin aetokthonotoxin, are also included. Algal toxins tested for include brevetoxin

This dataset is the result of a collaboration between the US Geological Survey Great Lakes Science Center and the Great Lakes Coastal Wetland Monitoring Program (CWMP). It contains information on habitat structure, water quality, vegetation, fish, and fish prey in Great Lakes coastal wetlands in the spring and fall from 2016 to 2018. The methods and resulting data mirror the CWMP's...

The data set contains geologic and mining engineering data from drill holes penetrating through the Cherokee coal bed interval of the Overland Member of the Paleocene Fort Union Formation in the Little Snake River coal field and Red Desert area in south-central Wyoming.
