Abstract

Fish tissue samples have been collected (2012 to 2019) from seven lakes in the Dehcho region of the Northwest Territories to determine fatty acid and mercury levels. To explore possible drivers of among-lake variability in fish mercury and fatty acid levels, lake-level environmental variables, including water chemistry and watershed characteristics, are being monitored. Community composition of algae and bacteria is also being investigated through rRNA analysis of water samples.

Purpose

This data was collected to explore possible drivers of among-lake variability in fish mercury and fatty acid levels in lakes of the Dehcho region of the Northwest Territories.
