| Abstract | Sediment cores collected from the landward side of a baymouth barrier in a lower estuarine environment of Chezzetcook Inlet contain proxy "signals" of onshore-directed storms that are manifested by the
sudden appearance of benthic and planktic Foraminifera species. These taxa have been eroded and transported from adjacent inner shelf open-marine environments. One relatively strong onshore-directed storm (hurricane?) event appears to have caused a
reduction in seawater exchange in the southeastern part of the inlet that persisted for at least several decades. In this particular barrier-protected lower estuarine depositional environment, foraminiferal storm-indicator species distributions in
older sediments seem to be spatially patchy. Consequently, in this Chezzetcook depositional setting, the successful reconstruction of a complete proxy storm record will require replicate coring and high-frequency core subsampling strategies.
