Ten cores were obtained from a marsh developed along Mad Island Slough, Texas, USA, upstream of a weir constructed in 1948. The cores were analyzed for cesium-137 to identify time-stratigraphic marker horizons and calculate recent sedimentation rates. The cesium-137 analysis provided a 1954 marker horizon in nine of the ten cores. A second marker horizon, present in all ten cores, consisted of an abrupt downcore change in lithology from dark organic-rich muds to grey organic-poor sands. This… Expand
