Title: Interdisciplinary characterisation of the macro-mechanical behaviour of offshore sediments from Northern Australia
Id: 2514
Investigator(s): Ryan Beemer
University of Western Australia [details]

Description: The behaviour of offshore sediments under load is very important to understand from an engineering prospective. It will dictate whether a submarine slope will fail and result in a tsunami. It will also determine the size of anchors needed to secure a renewable energy infrastructure. In spite of this importance very little public data on the mechanical properties of offshore Northern Australian soil is available to researchers. This project aims to collect and study the geotechnical behaviour of offshore soils in Northern Australia and make it available to the public. It will provide valuable data for researchers trying to understand and predict submarine landslides and for engineers researching anchoring systems for renewable energy systems. We propose collecting three box cores, with the Octopus box corer (Currently on board), at three different locations along the transit route. Our goal is to collect samples with high quantities of benthic or planktonic foraminifera with the specific goal of understand how the variation in the soils bio geology impacts their mechanical properties. This should be easily achieved across the majority of Northern and North West Australia.

Survey InvestigatorDescription

Andrew Bowie (UTAS) The application will support research to quantify the importance of iron-rich aerosols from Australia for marine biogeochemistry and ocean ecosystem health. The project will sample and conduct experiments on atmospheric particles containing terrestrial dust and bushfire smoke that are transported from Australia to its surrounding oceans. The application supports the training and research of two postgraduate students from IMAS-UTAS. The outcomes will provide a scientific basis for managing the complex role of iron in sustaining marine ecosystem biodiversity and for informing government policy on ocean fertilisation as a carbon mitigation strategy.
