Abstract
This presentation presents preliminary analyses from marine core records taken within the lagoons of the Montebello Islands, on the edge of the inner continental shelf off NW Australia (Fig. 1). These lagoons preserve unique records that document the post-glacial transgression and past cyclonic activity, and hence are likely to provide an unrivalled record of palaeoenvironmental change and landscape evolution for this region. This in turn provides critical contextual information to link with the archaeological and early faunal records in this region that indicate humans occupation from ~ 50,000 – 7,000 yrs ago (Veth et al. 2017). Whilst analyses are still ongoing, this presentation outlines initial geochemical (ITRAX) and chronological (14C) dates from some of these core records and some hot-off-the-press highlights from the June 2021 geoarchaeological fieldtrip!
