| Summary: | This dataset includes zooplankton and water quality data from 37 lakes sampled in the Northwest Territories, Canada, from the Dempster and Inuvik-Tuktoyaktuk Highways during July and August of 2017 and 2018. It was collected as part of a project to determine how physicochemical variables affect zooplankton and fish communities in small Arctic lakes. Funding provided by: Northwest Territories Cumulative Impacts Monitoring Program*Crossref Funder Registry ID: Award Number: CIMP197Funding provided by: Northwest Territories Cumulative Impacts Monitoring ProgramCrossref Funder Registry ID: Award Number: CIMP197 Our study includes 37 lakes located along the Dempster and Inuvik-Tuktoyaktuk Highways in the Northwest Territories. Lakes along the Dempster Highway were sampled between August 17th and September 1st, 2017 while lakes along the Inuvik-Tuktoyaktuk Highway were sampled between August 6st and August 27th, 2018. We collected data on surface area and maximum depth for each lake by constructing bathymetric maps using a Humminbird Helix 5 chartplotter (Johnson Outdoors Marine Electronics, Inc), in combination with Reefmaster bathymetry software (Reefmaster Ltd.). We also collected water quality data including Secchi depth (water clarity), turbidity, conductivity, dissolved oxygen (DO), pH, total nitrogen (TN), total phosphorus (TP), total organic carbon (TOC), calcium, chlorophyll-a, and water temperature (Table 1). To obtain water clarity measurements, we lowered a Secchi disk over the shady side of the boat at the deepest point on the lake. At the same location, we measured turbidity, conductivity, DO, pH, and temperature, using a Manta+ multiparameter probe (Eureka Water Probes) at a depth of 1 m. We also collected water for the measurement of TOC and calcium levels at the same site using a 3 m polyethylene integrated tube sampler. We used a Perkin Elmer Optima 8000 Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) instrument to measure calcium concentrations, and a Shimadzu TOC-LCPH Carbon ... |
