Friends of the Pleistocene Seminar Series

Marginal marine environments are dynamic systems which are susceptible to changes in environmental conditions. With increasing climate variability, rising sea levels, increased extreme weather events and also increased development for a growing population, it is crucial to understand the types of climate events and hazards which may affect these environments. One such way is to reconstruct past environmental conditions to understand natural baselines pre-anthropogenically modified to help inform future management response. This research concerns the environmental reconstruction of Lyttelton Harbour in Banks Peninsula, New Zealand which is a highly modified landscape that is poorly understood. Here I present preliminary results from a transect of sediment cores collected at the Head of the Bay, Lyttelton Harbour encompassing the marine-terrestrial interface. This research makes up my PhD project and is a multiproxy study utilising a combination of micro-fossil (palynology and foraminifera), geochemistry (X-ray Fluorescence), geochronology (radiocarbon, lead-210 and caesium-137 dating and particle size analyses.
