Determination of the seasonality effect on sea lamprey and TFM efficacy - Year One Determination of the seasonality effect on sea lamprey and TFM efficacy - Year One
Controlling larval sea lamprey (Petromyzon marinus) in Great Lakes tributaries with of 4-Nitro-3-(trifluoromethyl)phenol (TFM, a lampricide) is essential to reducing the number of spawning-phase sea lamprey, an invasive species capable of collapsing Great Lakes fisheries. An important component of treating streams with lampricide is ensuring that the proper amount of TFM is applied...
Principal facts of gravity data from the Stillwater Complex, Montana, 2013-2014 and 2020 Principal facts of gravity data from the Stillwater Complex, Montana, 2013-2014 and 2020
Gravity data were collected during three separate campaigns during July of 2013, August and September of 2014, and September and October of 2020 at 168 sites on and around the Stillwater layered mafic complex in southern Montana. Measurements were taken with Lacoste & Romberg G-64, G-550, and G-161 gravimeters and reduced to obtain the complete Bouguer anomaly, with reference ties to...
Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA
The data in this publication map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide regional context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. These data were collected as part of field activity 2021-022-FA and a collaboration with the National Park Service at Cape Cod National...
Data for "Weakening of Peridotite Sheared at Hydrothermal Conditions" Data for "Weakening of Peridotite Sheared at Hydrothermal Conditions"
This data release comprises three separate datasets and their accompanying metadata, in zip files. The data were acquired as part of a laboratory study of the response of ultramafic materials to shear at hydrothermal conditions. The principal dataset consists of the strength-displacement data from 28 friction experiments acquired on gouges prepared from peridotite rock samples and from...
Census counts of benthic foraminifera, environmental parameters (temperature, salinity, and oxygen concentration), and radiocarbon measurements from cores obtained under and near a whale-fall off western Vancouver Island, British Columbia, Canada Census counts of benthic foraminifera, environmental parameters (temperature, salinity, and oxygen concentration), and radiocarbon measurements from cores obtained under and near a whale-fall off western Vancouver Island, British Columbia, Canada
This data release provides census counts of benthic foraminifera (in percent for the total fauna and as raw counts for just the living specimens) as well as environmental parameters (temperature, salinity, and oxygen concentration) at the sampling sites, and radiocarbon measurements from selected push core samples obtained under and near a whale-fall off western Vancouver Island, British...
Temperature and invertebrate community composition at nearshore Great Lakes sites, 2013-2016 (ver. 2.0, April 2025) Temperature and invertebrate community composition at nearshore Great Lakes sites, 2013-2016 (ver. 2.0, April 2025)
Data on ambient water temperatures and invertebrate community composition from ~40 sites in the western basin of Lake Erie, Saginaw Bay (Lake Huron), Grand Traverse Bay (Lake Michigan) and Green Bay (Lake Michigan). These samples were collected as part of a study on spatial variation in ecosystem processes.
