Rebecca.Carey@utas.edu.au

Dr. Rebecca Carey is a Senior Lecturer and Australian Research Council DECRA fellow in the School of Physical Sciences in the Faculty of Science. She is a volcanologist with research themes in Earth and Marine sciences. Rebecca's research uses field studies, microanalytical and volatile analysis on the products of volcanic eruptions to understand magma's ascent to, and eruption at, the surface. Her expertise in volcanology of the modern seafloor and terrestrial settings has proven invaluable for knowledge and understanding of ancient volcano-sedimentary successions.

Biography

Rebecca completed her Undergraduate and Honours degrees at the University of Tasmania. She was awarded a PhD from the University of Hawaii at Manoa in 2008. She then pursued postdoctoral research at the University of California at Berkeley. Rebecca joined the University of Tasmania as an ARC Research Fellow at CODES/School of Physical Sciences in November 2011. She is now a Senior Lecturer within the School of Physical Sciences and a DECRA Postdoctoral Fellow.

Rebecca has authored more than 24 publications including a chapter in volcanology's leading reference publication The Encyclopedia of Volcanoes. She was also the Chief Editor of an AGU Monograph titled Hawaiian Volcanoes: From Source to Surface. Rebecca has had an early and continued record of success in attracting funding from both US and Australian funding agencies. She has sourced more than AU$2.8M in research funding, and ship time in-kind funding of >US$2.5M. In 2014 Rebecca was awarded the University of Tasmania's Vice Chancellor's Award for Research Excellence.

Rebecca's research is in four main areas: (1) magma ascent and degassing processes, (2) eruption plumes and pyroclast transport, (3) subaerial and submarine volcanic architectures in both the modern and ancient settings, (4) lava rheology and emplacement processes. Rebecca has served as Co-Chief Scientist for a US NSF-funded research voyage on submarine volcanic systems, which utilised underwater vehicle technologies, and she will be the Co-Chief Scientist for Geoscience on the 2016 RV Investigator voyage to the Kerguelen Plateau, Southern Ocean.

Research Themes

Rebecca's research and that of the Volcanology group aligns to the University's research themes of Earth's resources and Marine Science. Current projects combine volcanology, sedimentology, petrology marine geology and economic geology. Her ARC-funded projects have focused on understanding modern submarine volcanic arcs, eruption processes and transport into surrounding basins, which are then useful for understanding ancient volcanic settings and vectoring to mineralisation.

East Tasman Plateau - key to unravelling the onset of the Antarctic Circumpolar Current (2017)$19,180
Description
The onset of the Antarctic Circumpolar Current was controlled by the Eocene rifting of Tasmania from Antarctica and evolution of the deep Tasman Gateway (e.g. Stickley et al. 2004; Scher et al. 2015). However, the exact mechanism enabling the onset of the Antarctic Circumpolar Current through the Tasman Gateway remains controversial, with rapid Eocene deepening (Stickley et al. 2004) and northward migration (Scher et al. 2015) both implicated. The source of controversy lies in alternative interpretations of the paleoenvironment and subsidence of the East Tasman Plateau, and the Cascade Seamount that sits upon it. Driven by interpretations of IODP drill site 1172 on the East Tasman Plateau, which was used as the type example for the region, the South Tasman Rise region (Fig. 1) is thought to have deepened rapidly in the late Eocene enabling formation of the deep oceanic gateway (Stickley et al. 2004; Hill and Exon, 2004). In this interpretation, the East Tasman Plateau was close to sea level during the Late Eocene and has subsided ~2 km since then to its present depth. However, the subsidence history inferred from dredge samples from the Cascade Seamount, a ~2000 m seamount sitting atop the East Tasman Plateau is significantly different (summarised in Figure 2). Here, dredged volcanic samples recovered opportunistically by fishing vessels also indicate near sea level conditions in the Late Eocene (Fig. 2; Quilty, 1997; 2001), but are located ~2 km shallower than the shallow marine Late Eocene sediments in IODP core 1172. Options to resolve this observed discrepancy include: 1) An alternative interpretation of the shallow marine siliciclastic sediments below 356 m in site 1172. Instead of being deposited in-situ as proposed by Stickley et al. (2004), these sediments may have been first deposited on the top/flank of the Cascade seamount and subsequently transported to site 1172 in sediment gravity flows (e.g. Hill and Exon, 2004; Scher et al. 2015). 2) Existing age and paleo-environment constraints for the Cascade Seamount rely heavily on rocks opportunistically provided by fishing vessels. As such, there is a possibility that these samples were not accurately located. 3) The glauconitic sand/silt unit in Site 1172 was formed in-situ, though at a greater depth than suggested by Hill and Exon (2004).

East Tasman Plateau - Key to unravelling the onset of the Antarctic Circumpolar Current (2016)$0
Description
This frontier work will address first-order geoscientific questions on the evolution of the Tasman Seaway, a critical component in the onset of the Antarctic Circumpolar Current. Today, this current helps keep Antarctica cool, but its onset and role in stabilising icesheets on Antarctica remains controversial. This work will utilise marine geological data to resolve these outstanding tectonic and oceanographic questions around the evolution of key changes in past climatic and oceanographic conditions.

The role of hydrostatic pressure in modulating submarine silicic eruptions (2015 - 2017)$350,259
Description
Exploration on the modern seafloor reveals the deposits of deep (>1000m) silicic explosive eruptions, yet theory predicts that explosivity at these depths is largely suppressed. In 2012 the largest and deepest silicic submarine explosive eruption ever recorded took place at depths up to 1600m, also challenging this theory. This project leverages from a US research expedition to the eruption site. This project will constrain the physical and chemical factors that control explosivity using cutting-edge technologies. Australia's ancient submarine volcanoes host highly economic ore deposits. This research will enhance our ability to interpret ancient volcanic settings, thereby improving the potential for new ore deposit discoveries.

The geological evolution of Heard Island, Australian Antarctic Territory (2015)$19,434
Description
Our objectives are to:1. Determine the absolute age of 15 strategically selected lava flow samples on Heard Island using Ar-Ar dating techniques, permitting the recent volcanism of Heard Island temporally constrained.2. Integrate the Ar-Ar dating data from this project with historical and remote sensing data to construct a temporal sequence of lava producing events on Heard Island.3. Place the timing and magnitude of volcanic activity on Heard Island in the context of volcanism on the Kerguelen Plateau. MethodologyThe technique used to determine the ages of lavas will be Argon-Argon dating, a method that has been used successfully to date young lava flows in Hawaii. The samples used in this study will be analysed using a combination of X-ray fluorescence spectroscopy (XRF), petrography at the University of Tasmania and 40Ar/39Ar dating at Oregon State University, USA. The 40Ar/39Ar dating method is suitable for the study of relatively young (<Xxx ka) lava flow samples, as shown by recent research results from Prof. Duncans research group. The 40Ar/39Ar method involves sample irradiation in a nuclear reactor. This converts a small number of 39K atoms to 39Ar atoms (McDougall & Harrison, 1999). Following irradiation, the sample is fused in a vacuum system. The sample is heated in a series of steps starting below the temperature of fusion (McDougall & Harrison, 1999). For each step the argon is analysed isotopically in a mass spectrometer. The relative abundance of 40Ar, 39Ar, 37Ar, 36Ar +/- 38Ar are measured. The mass spectrometer used for the Argon dating is a Thermo Scientific Model Argus VI mass spectrometer. This spectrometer is the leading technology in the Ar-Ar dating method providing a larger range of data, improved accuracy and the capacity to analyse smaller samples than previous mass spectrometersOutcomesWe will produce:a) A geological map of Heard Island using the Ar-Ar age dates determined during this study.b) Publications to international peer-reviewed journals.c) Geological information pertinent to fundamental understanding of Australias only active volcano.Further, the outcomes of this study will inform the research mission voyage and dredging plans on the IMAS/UTAS Marine National Facility Cruise (R/V Investigator) to Heard Island in 2015/2016.

Submarine volcanoes: Degassing of silicic magma with implications for ascent and eruption processes (2011 - 2013)$280,000
Description
Submarine volcanoes are more common than those on land and yet we know very little about eruption processes in such settings. Unique sample suites recovered via submersible from deep-marine silicic volcanoes will be used in the first study to constrain magmatic volatile abundances and exsolution processes at known eruption depths. Water depth retards volatile resolution, which potentially strongly modulates eruption styles and intensities, with important yet uncertain consequences for the delayed release of volatiles influencing metal transport and syn-and-post eruptive ore deposition. These results will transform current understanding of submarine eruption processes and the older submarine volcanic rock formations that form the continents.
