Abstract:
This study focuses on the distribution of marsh benthic foraminifera, while utilizing cores from the Town of Hempstead's portion of the South Shore Estuary Reserve. Locations were cored throughout the Hempstead Bay area using a soil borer and a vibracore system. The cores were sampled at the surface and at depth, stained with Rose Bengal, and analyzed for foraminiferal assemblages. Rose Bengal Stain was used to distinguish living specimens from non-living specimens, allowing us to establish a baseline of living and dead foraminiferal assemblages. The foraminifera were extracted by removing them from sediments washed through a 63 micrometer sieve. Populations of Trochammina inflata, Trochammina macrescens, Tiphotroca comprimata, and agglutinated species are consistent with previous studies of marsh distributions observed in Nova Scotia and Southern California. Lead-210 and Cesium-137 radioisotopes provide age control.
