G. Heinson (Adelaide University) | Determine crust-mantle structure and anisotropy across the continental margin, from Archaean shield to ocean abyssal plain; Investigate the Canning Basin conductivity anomaly across the margin and its relationship to extensional faults imaged from deep-seismic profiles of the Fitzroy Trough. Up to twelve seafloor MT instrument (squares in Figure 1) will be recovered from the seafloor deployments sites established from the first leg of the cruise in August (FR 06/2000). |

G. Heinson (Adelaide University) | This information was taken from the Cruise Plan Geophysical Experiment (Heinson/White) The Carpentaria electrical conductivity anomaly is a major geological shear zone extending over a thousand kilometres in an approximately north-south orientation in northern Queensland. It has been mapped on land by various geomagnetic and magnetotelluric arrays, but the relationship between the conductivity anomaly and major tectonic boundaries is not straightforward. The offshore extent of the anomaly is unknown and poorly constrained by land measurements around the Gulf. The scientific objectives are therefore to: 1. Map the location of the Carpentaria anomaly and examine its spatial relationship with the tectonic structures in the region. 2. To determine the depth and length of the anomaly into the Gulf, and hence better understand the causes of high electrical conductance within the crust. 3. To relate the electrical properties to the tectonic evolution of northern Australia. Oceanographic Experiment (Tomczak) The purpose of the study is to develop a ship-borne rainfall measuring system based on the navigational radar. The method of measuring rain with the ship's radar was previously tried during the R/V Franklin voyage FR0796. It was shown that the radar can successfully monitor spatial rain distribution around the ship, which enables quantitative estimates of area-average precipitation using the thresholding technique. In the present proposal we attempt to substantially improve the accuracy of radar rainfall measurements by using advanced radar signal processing and thorough calibration and validation of rainfall measurements. Instruments used include Sea floor magnetometers, Acoustic recall system, FURONO Navigational Radar, Thermosalinograph, Bouy mounted Rainguages, Thoroid Bouys, Acoustic deck unit, Towed SP instrument. |
