Abstract:
During cruise SO292 of the RV SONNE from 15 May to 21 June 2022, oceanographic surveys were conducted on an isolated carbonate platform of the Queensland Plateau (northeast Australia). Two so-called Yoyo-CTD deployments were carried out here. The data sets obtained include directly measured parameters such as water temperature, conductivity, oxygen, fluorescence and turbidity as well as derived parameters such as potential temperature, density, salinity and sound velocity. The composition of the water masses and the oceanographic conditions contribute to the understanding of the sedimentation processes on an isolated plateau and help to understand the development of drift deposits. The CTD data also support the interpretation of the hydroacoustic and sedimentological investigations during the research campaign. The long-term CTD deployments of more than one day also make it possible to better understand internal water movements and to observe changes in the water column due to tides and internal waves.
