Total and methylated mercury data in Canadian Arctic Seawater (2013-2015)

To obtain the data, water samples of vertical profiles were firstly collected from the Rosette onboard the CCGS Amundsen, and then analyzed with instruments both onboard and in the lab in University of Manitoba. The total mercury were measured on a Tekran 2600 Model with the method EPA 1631 in the Portable In-situ Laboratory for Mercury Species onboard, while the methylmercury data were analyzed with the method EPA 1630 in the Ultra-Clean Trace Element Laboratory, which is located at the University of Manitoba. The main data types are the contaminants (along with O18 isotopes and dissolved organic carbon) concentrations in vertical profiles at the study sites.
