Sediment cores were retrieved from Burns Lake with a modified K-B corer (internal diameter ~6.35 cm) on February 14th, 2002 by A.J. Downie, Ian Sharpe, Mark West and Ian Wilson. Two cores were retrieved, one from the east basin at approximately 18 meters depth that was 32 cm in length, and a second fromthe west basin at approximately 6 meters depth that was 44 cm in length. Samples were sectioned in 1.0 cm intervals, which were stored at the ministry and later shipped to Queen's University where they were stored in our coldroom at 4* C. All the samples were weighed to determine the total wet weight of sediment prior to subsampling for 210Pb, loss-on-ignition and diatom analyses. Twenty intervals were subsampled for diatoms from each of the cores. For Burns East every one cm was sampled from 0 to 8.0 cm, then every two cm from 10 to 30 cm. For Burns West every two cm was sampled from 0 to 38.0 cm. FIfteen intervals were prepared for 210Pb analysis (see below) for Burns East and seventeen for Burns West and then Counted on the gamma counter facilities at PEARL, Queen's University.
