Extended time-series sensor data were collected between 2012 and 2016 in surface water of a tidal salt-marsh creek on Cape Cod, Massachusetts. The objective of this field study was to measure water chemical characteristics and flows, as part of a study to quantify lateral fluxes of dissolved carbon species between the salt marsh and estuary. Data consist of in-situ measurements including: salinity, temperature, pH, dissolved oxygen, redox potential, fluorescent dissolved organic matter, turbidity and chlorophyll. Surface water flow, water level and water elevation data were also measured. The data provided in this release represent a compiled data set consisting of multiple sensor deployments between 2012 and 2016.

This data contains coordinate locations for suspected historical spawning locations of lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) across the Lake Erie basin, including the Detroit River, Lake St. Clair, and the St. Clair River. Data points were summarized using ArcGIS 10.5. Data came from published and unpublished sources cited in the Atlas of the Spawning and Nursery Areas of Great Lakes Fishes (Goodyear et al. 1982) and other sources as described. Data points included were specific locations described as having the presence of eggs or spawning fish. Pseudo-absence data used for comparison purposes are also provided in this data release. First release: 2019 Revised: July 2022 (ver. 2.0)

This dataset reports select histopathological changes in liver, kidney, gonad, spleen, brain, heart, skeletal muscle, lung, or adrenal gland of zebra finches exposed to 15mg/kg, 18mg/kg, 30mg/kg, 60mg/kg, 75mg/kg, 125mg/kg, or 250mg/kg clothianidin (CTD) (with controls) by gavage, in water, or on millet seed either as a single dose or for 7 days. The goal of the project is to develop a subacute neonicotinoid toxicity model using zebra finches as a model passerine. We have completed two acute toxicity trials using CTD insecticide. Based on these studies, we estimate the no observable effect level (NOAEL) and the lowest observable effect level (LOAEL) for CTD in zebra finches to be 15 and 30 mg/kg body weight, respectively,...

Dataset includes publicly available geologic and rainfall data, and environmental and ecological data derived or collected for this project. Specifically, water infiltration measurements, interepreted field-saturated hydraulic conductivity values, ungulate activity, vegetation cover, general soil and weather conditions data are included. Soil samples were collected, lab analyzed, and are included in the dataset. Field-collected data are associated with plots that encompassed approximately a 3 x 3 m area; site data represent approximately 20 x 20 m. First posted: 4 March 2020 (available from author) Revised: April 13, 2020 (version 2.0) The revision is provided due to minor refinement of the dataset and updated...
