Biography

Taryn's expertise in geochemistry has been applied to two fields of research (i) palaeoceanography and (ii) environmental aspects of mining. Her palaeoceanographic research has focused on understanding climate processes in the Southern Ocean since the last glacial period (~20,000 years). She completed her PhD at the University of Cambridge, UK, where she worked on the development and application of radiogenic isotopes to reconstruct past climate and ocean circulation. This included using isotopes of Nd, Sr and Pb as provenance tracers of sediment to the ocean, and Th isotopes to quantify sediment fluxes. She is involved with two ANZIC funded projects and has participated in research cruises, including an International GEOTRACES cruise in the Tasman Sea.

Between 2012-2015, her postdoctoral experience at the University of Tasmania has involved developing new geochemical tests for mine water prediction. She also developed a new method for characterising dust, in particular the composition of the fraction most harmful to humans. She has also studies the mobility of metals and metalloids at historic mine sites. During this time has worked closely with the mining industry in Tasmania and industry stakeholders in partnership with CRC ORE.

Research Themes

Taryn's research aligns with the University's Marine, Antarctic and Maritime theme. Her current research involves using seawater and marine sediment cores from near Antarctica to understand past changes in the Antarctic ice sheet. The data generated in this work will improve our understanding of the role of ice-ocean interaction on melting of the ice sheet, and mechanisms resulting the contribution of Antarctic ice melt to sea level rise. She is also interested in reconstructing changes in dust inputs to the Southern Ocean and changes in ocean circulation and nutrient distribution since the penultimate deglaciation.

How did the Ross ice shelf respond to changes in ocean circulation as the climate warmed during the last deglaciation (2017)$24,500
Description
The largest uncertainty in estimates of the future sea level rise is due to the response of Antarctic ice shelves to the warming of the surrounding oceans. Increased melt at the base of the fringing ice shelves results in more rapid mass loss from the Antarctic Ice Sheet (AIS) and faster sea level rise. However, the processes regulating melting of ice shelves are poorly constrained. To better understand the mechanisms that lead to the instability of the ice shelves the proposed research will use sediment cores in the Ross Sea to test how the Antarctic Bottom Water (AABW), a climatologically important water mass that ventilates the deep ocean. The formation of AABW acts as a barrier 'protecting' the ice front from warmer deep Southern Ocean waters. However, as the climate warms AABW formation is thought to decrease, which results in warmer waters encroaching the base of the ice shelf, leading to rapid ice loss. The applicant, Dr Taryn Noble will test this hypothesis by applying a range of differ techniques to sediment cores in the Ross Sea.

Response of the Totten Glacier to past climate warming (2017 - 2019)$115,397
Description
Understanding how, where and why ice sheets lose mass is a priority theme established by the international scientific community to meet the challenges of global change. The Totten Glacier is a major outlet glacier draining a large area of East Antarctica and has the potential to contribute 3.5 metres to global sea level rise. It has some of the fastest thinning rates and the potential to make significant contributes to global sea level rise. Recent evidence suggests that this unprecedented melting is part due to incursion of warm water at its base. This project aims to better understand the interaction between the ocean and Totten ice shelf during climate warming, by examining past warming events in marine sediment cores. Mineralogical and geochemical assessment of the sediments will provide key information on ice sheet and ocean circulation dynamics. Study of the sediment provenance will also allow us to probe the subglacial Wilkes Land basement geology drained by the Totten Glacier.

The impact of changing ocean circulation on the Antarctic ice shelf (2016 - 2018)$276,000
Description
The largest uncertainty in predictions of future sea-level rise is our understanding of how the Antarctic ice shelves will respond to warming of the surrounding oceans. We will investigate the affect of changes in ocean circulation on the melting of the Antarctic ice shelf in a warming climate state. Seawater samples from the Mertz glacier region will be used to document the current ocean-ice configuration and nearby marine sediment cores will be used to go back in time, to when sea-levels rose abruptly, as the climate transitioned out of the Last Glacial Maximum.

The establishment of ocean anoxia and ocean acidification during the PETM: Understanding the biological and chemical response on a regional and global scale. (2016)$20,000
Description
The Paleocene-Eocene Thermal Maximum (PETM; ~56 Ma) is one of the most intense and abrupt intervals of global warming in the entire geological record. The warming event has been linked to a rapid increase in the concentration of greenhouse gases in Earth's atmosphere, which acted to trap heat and increase global temperatures by more than 5 'C in just a few thousand years. Feedback from this event perpetrated the establishment on acid waters, leading to overturn of the carbonate compensation depth, and biological turnover.This project, funded by ANZIC-IODP, will sample and analyse cores from the Newfoundland shelf that archive the PETM. The project will utilise a range of organic and inorganic geochemical methods inorder to understand the conditions in the build-up and through the PETM

Improved quaternary age models for Ocean Drilling Program cores from the southern Australian dust corridor (2015)$7,440
Description
This project will use radiocarbon dating to develop and refine agemodels for sediment cores from the Australian region recovered by the Ocean Drilling Program. The age models will enable reconstruction of key oceanographic processes across the most recent glacial-interglacial cycles of the Quaternary. In particular, with separate funding, we will reconstruct the origin and magnitude of dust deposition to this region, in order to constrain the nature and impact of iron fertilization of biological carbon uptake during coldglacial climates.

Submarine volcanism and hydrothermalism around Heard and McDonald Islands (2015 - 2016)$65,600
Description
The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the Southern Ocean. This project will explore for the first time the role of undersea "hotspot" volcanoes in supplying iron to surface waters, thus linking the solid earth and the biosphere. Existing data indicate that fields of submarine volcanoes extend for several hundred kilometres from Heard and McDonald islands, among the world's most active hotspot volcanoes. We will produce a three dimensional, high-resolution bathymetric and backscatter map of the seafloor surrounding the islands. We will map the water column for chemical signatures of hydrothermal activity. From this mapping we will identify and sample candidate active submarine volcanoes, a first for this region. We will measure iron abundance, and reactivity in buoyant plumes over and downstream of these volcanoes, and evaluate physical mixing processes that might deliver this iron to surface waters.

A multi-proxy quantification of Australian dust deposition over the last glacial-interglacial transition (2013)$24,950
Description
This research will be the first to quantify dust deposition in the Australian region using 230Th normalisation. It will extend existing records to the south, thereby identifying whether there is any dust transport during the LGM along a path from Australia to Antarctica. The rate of dust deposition to any site in the ocean depends on many factors, including wind strength and position, source area size, and the relative importance of wet versus dry deposition. By characterising the rate of accumulation, provenance and size spectrum of terrigenous material at three sites within the SE Australian dust plume, analyses will help constrain the evolution of these factors through time.

Southern Ocean's role in moderating glacial-interglacial variability in atmospheric pCO2: Decoupling nutrient cycling and ocean circulation (2013)$25,000
Description
This research builds on seminal work which used silicon isotopes to demonstrate that the silicic acid concentrations in the South Atlantic sector of the Southern Ocean remained constant over the past 150 ka. In contrast, the Pacific sector showed higher glacial silicic acid concentrations during MIS 2 relative to MIS 1, supporting the SALH. However, during the penultimate deglaciation, MIS 6 to 5e, the opposite trend was recorded in the Pacific sector, where lower silicic acid concentrations were observed in the glacial relative to the interglacial (MIS 5e) period. The aim of this research is to explain these puzzling trends in the Pacific Southern Ocean. In particular, it will untangle the relative contributions of water mass sourcing and nutrient cycling to the silicic acid budget. The project will do this by producing high-resolution records for the penultimate and last deglaciation of: 1) silicic acid concentration, using silicon isotopes and; 2) Water mass origin, using Nd isotopes.
