Research outputs 2014 to 2021

This project made use of a suite of palaeoecological approaches to reconstruct a chronology of change in coastal water quality over the last approximately 100 years. The biogeochemical proxies addressed phytoplankton composition and biomass, temperature and terrestrial influences. Where possible these were matched to historical land/water use, meteorological or hydrological observational records.

The project examined sediment cores from three coastal locations in the Kimberley region, Koolama Bay (King George River), Cygnet Bay and Roebuck Bay. Each sampling location provided a contrast with which to evaluate changes over either a spatial or temporal gradient of human or natural influences.
