Caitlin T Rumrill
I am an Ecologist at the USGS Forest and Rangeland Ecosystem Science Center in Corvallis, OR.
Our research focuses on spatial relationships of contaminant presence and bioavailability within landscapes and effects on environmental health, primarily mercury in aquatic ecosystems.

Science and Products
Mercury concentrations in amphibian tissues and egg masses, fish tissues and sediment in subarctic, freshwater systems near Churchill, Manitoba, 2015-2019
Comma-separated values (.csv) files containing data related to amphibian, fish, and sediment sampling near Churchill, Manitoba between 2015-2019. Data files contain mercury concentrations in amphibian and fish tissues, amphibian egg masses, and sediment, as well as amphibian and fish morphometrics, life stage, site distance to coast and biome where the samples were collected.
Total mercury concentrations in bat tissues and blood from southwestern U.S. National Parks in 2023
Comma-separated values (.csv) file containing data related to bat sampling from southwestern U.S. National Parks in 2023. Data file contains mercury concentrations in bat tissues and blood.
Mercury concentrations in amphibian tissues across the United States, 2016-2021
Comma-separated values (.csv) file containing data related to amphibian sampling across the United States between 2016 and 2021. Data files contain mercury concentrations in amphibian and dragonfly tissues, mercury concentrations in sediment, as well as amphibian morphometrics, and habitat and climate characteristics where the samples were collected.
Assessment of Mercury and Mercury Stable Isotopes in Sediments and Biota from Reservoirs and Remedial Zones within the Saint Louis River, Minnesota
This data release includes mercury concentrations and mercury stable isotope measurements measured in sediments and biological tissues collected from the Saint Louis River located in Minnesota. Sediments and biota were collected by the U.S. Geological Survey, U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, and federal contractors (Battelle) from 2017-2021. Collection regions in
Contaminants in larval, juvenile, and adult Pacific lamprey (Entosphenus tridentatus), Oregon, 2017-2021
This data release contains analytical results of organohalogenated compounds and mercury in lamprey and sediment that were collected from rivers in Oregon and along the Pacific northwest coast from 2017 to 2021. In 2017, 20 lamprey were collected off the Washington and Oregon coasts by the National Oceanic and Atmospheric Administration. These ocean-caught juvenile lamprey were parasitizing target
Total mercury and methylmercury in biota from Cottage Grove Reservoir, Coast Fork Willamette River, and additional reservoirs in Oregon (ver. 2.0, February 2024)
Comma Separated Value (CSV) file containing data related to total and methyl mercury concentrations in biota from the Willamette Basin in Oregon; specifically, Cottage Grove Reservoir, waters upstream of the reservoir, and additional reservoirs within the Willamette Basin.
Broad-scale assessment of methylmercury in adult amphibians
Mercury (Hg) is a toxic contaminant that has been mobilized and distributed worldwide and is a threat to many wildlife species. Amphibians are facing unprecedented global declines due to many threats including contaminants. While the biphasic life history of many amphibians creates a potential nexus for methylmercury (MeHg) exposure in aquatic habitats and subsequent health effects, the broad-scal
