Using Carbon, Nitrogen, and Mercury Isotope Values to Distinguish Mercury Sources to Alaskan Lake Trout

Metadata Updated: May 30, 2022

This data release includes results of raw water, soil, seston, and fish tissue samples collected from lakes in southwestern Alaska between 2011 and 2016. Specifically, these data include total mercury and methylmercury concentrations in water, size-sieved seston, and particulate matter of 13 remote lakes. Additionally, these data include soil and volcanic ash measurements from the surrounding watersheds. Finally, these data include energetic profiling of seston, lake trout, and sockeye salmon as well as mercury isotope measurements of the fishes. These data are important when interpreting mercury mass balance flows and bioavailability to the food web and are a part of an associated journal article published in Environmental Science and Technology Letters (https://doi.org/10.1021/acs.estlett.2c00096).

This dataset is associated with the following publication: Lepak, R., J. Ogorek, K. Bartz, S. Janssen, M. Tate, Y. Runsheng, J. Hurley, D. Young, C. Eagles-Smith, and D. Krabbenhoft. Using Carbon, Nitrogen, and Mercury Isotope Values to Distinguish Mercury Sources to Alaskan Lake Trout. Environmental Science & Technology Letters. American Chemical Society, Washington, DC, USA, 9(4): 312-319, (2022).
