Watch Lake was cored in July 21, 1998 by Rick Nordin and Bob Grace. The core was retrieved using a modified K-B corer (internal diameter ~ 6.35 cm) from the deep basin. On shore the core was sectioned into 0.5-cm intervals into 120-ml plastic containers. These samples were shipped on ice to Queen's University where they were stored in our coldroom at 4*C. Each container was weighed to determine the total wet weight of sediment then subsasmpled for 210Pb, diatom and pigment analyses. Twenty intervals (every 2 cm) were subsampled for diatom and pigment analyses, and sixteen intervals for 210Pb analysis. Subsamples for analysis of pigments were sent to Prof. Leavitt at University of Regina. Prepared samples for 210Pb analysis (see below) were sent to MYCORE Ltd.
