Description, dates, and locations of lava samples collected during the Pu‘u‘ō‘ō (1983–2018) and summit lava lake (2008–2018) eruptions of Kīlauea Volcano, Island of Hawai‘i Description, dates, and locations of lava samples collected during the Pu‘u‘ō‘ō (1983–2018) and summit lava lake (2008–2018) eruptions of Kīlauea Volcano, Island of Hawai‘i
This data release contains information about the lava samples that were collected during two volcanic eruptions of Kīlauea Volcano, Island of Hawai‘i. The first eruption occurred from 1983 to 2018 at Pu‘u‘ō‘ō and the second occurred contemporaneously from 2008 to 2018 at the summit lava lake. The data release provides a comprehensive list of lava samples that are currently stored in the...
Detections, Physical Captures, Water Quality, and Fish Health associated with Endangered Suckers in Three Net Pens in Upper Klamath Lake, 2020 Detections, Physical Captures, Water Quality, and Fish Health associated with Endangered Suckers in Three Net Pens in Upper Klamath Lake, 2020
To determine how initial length affects survival of captively-reared juvenile suckers, we introduced Passive Integrated Transponder (PIT) tagged juvenile suckers into three net pens in Upper Klamath Lake. The suckers originated from the U.S. Fish and Wildlife Service's Sucker Assisted Rearing Program in Klamath Falls, Oregon, which rears suckers collected as larvae in Upper Klamath Lake...
Detections, Physical Captures, Water Quality, and Fish Health Data Related to Suckers Held in Four Net Pens in Upper Klamath Lake, 2019 Detections, Physical Captures, Water Quality, and Fish Health Data Related to Suckers Held in Four Net Pens in Upper Klamath Lake, 2019
To determine how a low cost oxygenation system affected survival of captively reared juvenile suckers, we introduced Passive Integrated Transponder (PIT) tagged juvenile suckers into three net pens in Upper Klamath Lake. The suckers originated from the U.S. Fish and Wildlife Service's Sucker Assisted Rearing Program in Klamath Falls, Oregon which rears suckers collected as larvae in...
Detrital Zircon U-Pb and Hf isotope data from selected Appalachian rivers Detrital Zircon U-Pb and Hf isotope data from selected Appalachian rivers
This data release contains zircon U-Pb (n=1467) and Hf (n=332) data for five modern rivers (Connecticut, Susquehanna, Roanoke, Peedee, and Chattahoochee) draining the Appalachian mountain belt. The data show that zircon crystallization ages are characterized by several discrete populations that often correspond with orogenic episodes in the Mesoproterozoic and Paleozoic, with distinct...
Developing a Stochastic Hydrological Model for Informing Lake Water Level Drawdown Management Developing a Stochastic Hydrological Model for Informing Lake Water Level Drawdown Management
This data release consists of four datasets which were used for evaluating winter drawdown (WD) lakes to follow the Massachusetts general WD guidelines. The first dataset ("Water level observations.csv") provides water level monitoring data of 21 (18 WD and 3 non-WD) recreational lakes in Massachusetts from 2014 to 2018. The water levels were measured by paired nonvented pressure...
Development and testing of a qPCR assay for Lampsilis siliquoidea eDNA Development and testing of a qPCR assay for Lampsilis siliquoidea eDNA
Data describe specificity and sensitivity testing for the L.sil2 assay. This assay is used to amplify eDNA from the freshwater mussel Lampsilis siliquoidea.
Development of fluorescent staining method and effect of fluorescent staining on benthic invertebrate picking efficiency Development of fluorescent staining method and effect of fluorescent staining on benthic invertebrate picking efficiency
This is a tabular data set that includes intensity and saturation measurements of benthic invertebrates, sample residue, and preservative from samples stained with three fluorescent dyes for the development of a fluorescent staining method to enhance picking efficiency. This data set also contains data evaluating a selected fluorescent method's effects on picking efficiency and...
Development, testing and use of four species-specific qPCR assays for freshwater mussel eDNA detection in the Niobrara River Development, testing and use of four species-specific qPCR assays for freshwater mussel eDNA detection in the Niobrara River
This data consists of information on the specificity and sensitivity of 4 species specific qPCR assays for the detection of eDNA from 4 species of freshwater mussels, specifically Lampsilis cardium, Lampsilis siliquoidea, Pyganodon grandis, and Anodontoides ferussacianus. The data also contain the results of eDNA sampling in Niobrara River at Niobrara National Scenic River and Agate...
DGMETA (Version 1): Dissolved Gas Modeling and Environmental Tracer Analysis Computer Program DGMETA (Version 1): Dissolved Gas Modeling and Environmental Tracer Analysis Computer Program
DGMETA (Dissolved Gas Modeling and Environmental Tracer Analysis) is a Microsoft Excel-based computer program that is used for modeling air-water equilibrium conditions from measurements of dissolved gases and for computing concentrations of environmental tracers that rely on air-water equilibrium model results. DGMETA can solve for the temperature, salinity, excess air, fractionation of...
Diet Composition of Southern Beaufort Sea Polar Bears Sampled in Spring from 2004 to 2016 Estimated with Quantitative Fatty Acid Signature Analysis Diet Composition of Southern Beaufort Sea Polar Bears Sampled in Spring from 2004 to 2016 Estimated with Quantitative Fatty Acid Signature Analysis
These data are estimates of the proportional contributions of bearded seal, beluga whale, bowhead whale, and ringed seal to the diets of southern Beaufort Sea polar bears. Fat biopsy samples were collected from polar bears captured or biopsy darted along the north coast of Alaska or on offshore ice during March, April, and May from 2004 to 2016. Fatty acid data of the above four prey...
