Water chemistry data from the Inuvik-Tuktoyaktuk region from June/July 2017
(2021) Jennifer Korosi
Lake water quality data was collected from 65 lakes in the Inuvik-Tuktoyaktuk region (Inuvialuit Settlement Region; Northwest Territories, Canada) between June 28 and July 5, 2017. Of the 65 lakes, 26 were impacted by shoreline retrogressive thaw slumps. Lakes were accessed by helicopter, and sampling was conducted from the helicopter pontoons as a platform and taken from the centre of the lakes. Water depth was recorded using a hand-held sonar device, and vertical temperature profiles were taken using a Hanna multi-probe. Surface water samples (~0 – 2m depth) were collected using a vertical Van Dorn water sampler and shipped to Taiga Environmental labs in Yellowknife for water chemistry analysis, which is a CALA accredited facility. Data was included in: Murdoch, A., Gray, D.K., Korosi, J., Vucic, J.M., Cohen, R.S. and Sharma, S., 2021. Drivers of fish biodiversity in a rapidly changing permafrost landscape. Freshwater Biology, 66(12), pp.2301-2321. https://doi.org/10.1111/fwb.13834
