NMK_IIA (Lough Namackanbeg) * Latitude: 53.285240 * Longitude: -9.300710 * Date/Time: 1990-05-12T00:00:00 * Method/Device: Livingstone corer (LIVC) * Comment: Lake size 180 m x 80 m, lake area 1.2 ha. Lake has largely filled-in since early 20C; now a Schwingmoor; there are effectively 2 small basins; core taken in larger northern basin. Cored from a platform supported by sedge-rich vegetation where probing revealed the thickest sediments. Core taken in 1-m drives
