Geophysical imaging, structural analysis, alteration geochemistry of Macquarie Island crust, to constrain tectonic, and hydrothermal history of the ocean floor.Although oceanic crust covers about 60% of the Earth, relatively little is known of its geology and the processes that have created it. Macquarie Island represents a unique subaerial exposure of the seafloor, and an exceptional environment for active study and research into the ocean crust. We plan to utilise geological and geophysical techniques to help us better understand the lithological compl

ULF induction magnetometer data from Australian Antarctic and subantarctic stationsSpace weather is a significant hazard to modern technology. It results from energization of the Earth's radiation belts and subsequent transport of relativistic particles to low altitudes. Plasma waves convey energy and interact with particles throughout these regions but also provide a convenient ground-based diagnostic of these processes. We will use data from current and planned spacecraft miss

Locating an ice-covered Antarctic landfill using ground magnetometryThe abandoned Wilkes Station remains a significant waste problem in Antarctica with a large proportion of this waste buried in the ice for much of the year. A large proportion of this waste is locked up beneath the ice at the northern boundary of Newcomb Bay on the Clark Peninsula, approximately 3 km north of Casey Station. The magnetometer survey was conducted to delineate the spatial extent of t

Ice Flow History of the Thwaites Glacier, West AntarcticaThis data set contains past flow lines of Thwaites Glacier. The flow lines were identified using layer patterns tracked between parallel radar layers, from a radar profile of the Thwaites Glacier catchment. The radar data was run and processed by the University of Texas Institute for Geophysics. The flow lines were identified from distinct layer patterns tracked between parallel radar layers. Data

Gravity and Magnetic Data in the Vicinity of Virgin Valley, Southern NevadaGravity and magnetic data were collected in the vicinity of Virgin Valley to help better characterize the buried sedimentary Mesquite and Mormon basins. Detailed gravity measurements were made over the buried saddle between the Mesquite and Mormon basins, discovered by earlier gravity studies, in order to calculate the depth to pre-Cenozoic basement. The purpose of this study was to provide estima

Ground Magnetic Data from within the Long Valley Caldera, CaliforniaThe past two decades have been a period of unrest for the Long Valley caldera of eastern California. The unrest began in 1978 and continued through late 1999 and included recurring swarms of moderate earthquakes, as well as uplifting of the Resurgent Dome, which has totaled approximately 80 cm. It is believed that the seismicity is accompanied by magmatic intrusion beneath both the Resurgent Dome

Monitoring of the Antarctic geomagnetic field and VLF variations for trendsThe interaction between the solar wind and the Earth's magnetic field creates a vast magnetic cavity within the solar wind flow, known as the magnetosphere. Through various solar wind-magnetosphere interactions, about one million megawatts of energy enters the magnetosphere to drive electrical currents, energize plasma, and produce complex and variable patterns of plasma convection. Since the iono
