Palaeoecology and Chronology
Lake Hawden, New Zealand, site of a study
on late glacial climate change in the Southern
Hemisphere using chironomids (non-biting midges)
and pollen from the sediments (PI: Dr Nicki Whitehouse)
Stable isotope results (delta 13C and delta 15N)
from a stratified hyraceum deposit
from South Africa (Collaboration with
Dr Brian Chase , co-I Prof Paula Reimer)
The Palaeoecology and Chronology focus group in the School of Geography. Archaeology and Palaeoecology is an interdisciplinary group of researchers who work both independently and collaboratively on a broad range of topics. Past environmental change is studied using biological proxies including pollen, molluscs, insects, testate amoeboe, diatoms, macrofossils, tree-rings and peat humification, as well as stable isotopes. Chronological projects include constructing radiocarbon calibration curves and models for age-depth analysis, investigating marine and freshwater radiocarbon reservoir effects, analysis of tephra in ice cores and sediments and dendrochronology.
Members of the focus group meet to read and discuss pre-circulated papers. The meetings are open to interested individuals, postgraduate and staff, from other areas of academic study.
