Zanna Chase is Professor of Chemical Oceanography at the University of Tasmania, Australia. She works within the Oceans and Cryosphere Centre at the Institute for Marine and Antarctic Studies. Her research focuses on the interaction between chemical cycles and biological activity in the oceans, and how these are affected by climate. Understanding of these interactions, both in the modern ocean and the paleo-ocean, is necessary to predict the oceans' response and contribution to future climate change.

She is particularly interested in the role of the Southern Ocean in long term climate change. In her research, Zanna applies a variety of geochemical proxies in sediment cores, including long-lived, naturally occurring radioisotopes to reconstruct particle flux, and redox-sensitive metals to reconstruct ocean oxygenation. She is also involved in research to improve our understanding of trace metal proxies used in paleoceanography, primarily through participation in the international GEOTRACES program.

Zanna is active in research leadership at the University of Tasmania, having served on the IMAS Research Committee for many years, and as the Associate Head of Research for IMAS since 2019. Zanna is a sea-going oceanographer, and has participated in over 21 research voyages, many with leadership roles. Her research is complemented by teaching in oceanography and biogeochemistry.

Biography

Zanna’s contributions to chemical oceanography are primarily in the fields of Paleoceanography and Biogeochemistry. Her research has often combined these two fields in innovative ways, building on insights from present-day process studies and modelling to understand the past. Zanna studied biology and mathematics as an undergraduate, and then completed a master’s degree in biological oceanography, all at McGill University. She then moved into chemical oceanography and paleoceanography as a PhD student at Columbia University’s Lamont Doherty Earth Observatory. Before joining UTAS and IMAS in 2010, she was on the faculty at Oregon State University.

Seasonal changes in calcification depth, population structure and shell morphology of Southern Ocean pteropods (2023)$7,232

Description: As surface aragonite undersaturation events start to rapidly spread at the end of this decade and cover approximately 30% of the Southern Ocean surface by 2060, this PhD project will be the first study to explore the specific depth ranges where Southern Ocean pteropods typically form their aragonite shells known as the calcification depth. By combining the study of seasonal changes in calcification depths, biological mechanisms and shell morphology, this project aims to improve understanding of whether and how these indicator species will survive under rapid changing conditions of seawater carbonate chemistry throughout the Southern Ocean.

Testing the White Ocean hypothesis to inform Ocean Alkalinity Enhancement (2022)$259,246

Description: Ocean Alkalinity Enhancement (OAE) increases the chemical storage capacity for atmospheric CO2 in seawater. A presumed strength of OAE is the permanence of the CO2 storage, which is thought to be in the range of 100,000 years, equivalent to the residence time of alkalinity in the oceans. However, this presumption neglects that calcifying organisms are responsive to changes in carbonate chemistry, with theory predicting an increase of calcification under higher alkalinity and associated increases of seawater pH (the white ocean hypothesis). If true, OAE efficacy could be lower and carbon storage permanence much shorter than widely believed because stimulated calcification would reduce the deliberately added alkalinity, thereby unlocking sequestered CO2. This project will test the white ocean hypothesis, focusing on the Black and Caspian Seas as natural analogues for a high-alkalinity ocean. We will use satellite and Argo float data to assess if the prevalence of calcifier increases relative to other phytoplankton under elevated alkalinity. Along this process, satellite and Argo float data will also be utilized to check if phytoplankton bloom phenology is different in these high alkalinity seas than in other ocean regions, which will be an important indicator if alkalinity can impact ecosystem functioning. Furthermore, aim to ground-truth our findings by participating on a research voyage to study OAE impacts on live plankton communities including calcifiers. Next to the OAE sensitivity to calcium carbonate (CaCO3) production, OAE efficiency can be reduced if more CaCO3 is exported out of the surface ocean under increased alkalinity. We will apply a tracer-based approach in combination with a targeted CaCO3 dissolution experiment to test if increased seawater alkalinity increases CaCO3 export from the surface ocean. Our study will clarify if the efficacy of OAE could be compromised via complicated feedbacks in the global CaCO3 cycle. We will provide large-scale and real-world context for the OAE assessment, which will be central to the public debate around this CO2 removal method.

Is there a climatic tipping point for Antarctic Bottom Water formation? (2022 - 2024)$672,000

Description: Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet it is highly sensitiveto climate change. This project will analyse new seafloor, core and water samples from Cape Darnley, EastAntarctica, collected on a voyage in early 2022. This new data will be used in combination with a high resolutionregional model, to understand modern and past Antarctic Bottom Water formation under different climate states(warmer and colder than present), to assess climate tipping points. The anticipated benefits include a betterunderstanding of future climate change on this important water mass.

Using the last glacial cycle to understand carbon-climate feedbacks (2022 - 2024)$523,674

Description: This project aims to investigate how the ocean's carbon cycle will respond to anthropogenic climate change by examining its response to past climate variability. The project expects to generate new records of biological productivity, iron fertilisation by dust, and inorganic and organic carbon cycling in the poorly studied Indian sector of the Southern Ocean. Expected outcomes include new datasets to test climate models, and a new method to detect temperature-driven changes in microbial decomposition. This should lead to significant benefits including more accurate estimates of how much carbon humanity can safely emit, and the science to inform whether Australia should adopt ocean fertilisation as a strategy to combat climate change.

The Australian Centre for Excellence in Antarctic Science (2020 - 2025)$22,389,928

Description: The Centre will revolutionise predictions of the future of East Antarctica and the Southern Ocean. Changes in the Antarctic will be profoundly costly to Australia, including sea-level and fisheries impacts; but the speed and scale of future change remains poorly understood. A new national-scale and interdisciplinary Centre is required to understand the complex interactions of the ocean, ice sheets, atmosphere and ecosystems that will govern Antarctica's future. The Centre will combine new field data with innovative models to address Australia's Antarctic science priorities, train graduate students, develop leaders, engage the public, and enable major economic benefit as Australia adapts to climate change in the coming years and beyond.

Tracing nutrient sources in the Derwent Estuary, Tasmania (2020)$0

Description: This project aims to unravel the history of nutrient loads into the Derwent Estuary, Tasmania, and to identify their potential sources using isotopic fingerprinting. While several studies have investigated the metal history in the Derwent Estuary associated with zinc smelting (e.g. Hughes, 2014; Townsend & Seen, 2012), nothing is known about the accumulation of nutrients (nitrogen, phosphorus) in the sediment as an indicator of nutrient loads. An increase in surface water nutrient concentrations in the River Derwent is believed to have caused summer-time blue green algal blooms in recent years, however, nutrient monitoring and load estimates for catchment and estuary is difficult due to generally low concentrations in the River Derwent (below reporting limits), the variability in river flow due to water regulation for hydro-electricity production, and the seasonality of potential nutrient sources (Proemse et al., 2018). One hypothesis is that elevated levels of nitrogen is the key nutrient stimulating algal growth in catchment and estuary, and is the cause of the problem; however, the catchment contains many sources of nitrogen, including wastewater treatment plant effluent, fish hatchery effluent, dairy farm runoff and manure, fertilizers, and stormwater runoff. In this project we therefore use sediment records to investigate how nutrients loads into the estuary have changed over recent years, and use stable isotopetechniques to investigate their sources.

Physical, chemical and biogeochemical gradients in the East Australian Current (2018)$0

Description: This voyage will train Masters students from the University of Tasmania in oceanographic methods. Students will map changes in temperature, salinity and nutrients along 2,500 km of the eastern Australian coast. Biological sampling will document the changes in ocean plankton from the subantarctic waters near Tasmania to the tropics. By observing the change in current biological communities along a south-to-north temperature gradient, students will gain an appreciation of changes that may occur over time due to climate change. Students will gain valuable training in oceanographic field techniques, data analysis and communication.

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)$300,769

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.

Reconstruction of ocean (de)oxygenation in the South East Pacific over the last glacial cycle (ODP Leg 202) (2016)$18,720

Description: This project will generate proxy records of bottom water oxygen and bio-productivity at three ODP Leg 202 sites on the south-central Chile margin back to the last interglacial period, reconstructing the full glacial cycle and the response to millennial-scale climate events. This will allow us to address two main scientific questions:Question 1: When did oxygen first decrease in the SE Pacific, within the sequence of events beginning at glacial inception?Question 2: How did oxygenation of the SE Pacific respond to the millennial-scale climate events that occurred during the last glacial period?

Insights from the past: Using the history of Antarctica to improve projections of global sea level rise (2016)$14,914

Description: The magnitude of future increases in global sea level is a question of critical societal and economic relevance. However, current projections of both short-term and long-term sea level rise are highly uncertain. For a mid-range climate scenario, for example, the most precise statement that can be made is that it is likely that global sea level will rise by between 32 and 63cm during the 21st century (Church et al., 2013). The largest single source of uncertainty is associated with the mass balance of the Antarctic ice sheet. In the short-term, it cannot even be stated with certainty whether Antarctica will have a positive or negative impact on global sea level (Church et al., 2013). In the long-term, the possibility exists that melting of the coastal shelves around Antarctica will lead to an irreversible commitment towards ongoing sea level rise. However, because of limitations in our understanding of icesheet dynamics, the magnitude of this commitment could lie anywhere between 0.6 and 3m (Golledge et al., 2015). Reducing these uncertainties is critical for climate change adaptation and mitigation.Through a ground-breaking integration of data and models, this project will use the history of the Antarctic ice sheetto improve our ability to predict future changes in global sea level. Data on past climates can tell us how the Antarctic ice sheet and global sea level have evolved. We will use this data to confront the ice sheet models that are used to predict future changes. By constraining the models, we will use the Earth's climatic history to improve our understanding of the physics of the Antarctic ice sheet. This will allow us to constrain the role of Antarctica in drivingchanges in global sea level, and thus allow for improved projections of future sea level rise. The project will therefore address a question of considerable societal and economic relevance.

Hot iron: Are submarine volcanoes important for Southern Ocean iron supply? (2015 - 2017)$233,400

Description: The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the SouthernOcean. This project will explore for the first time the role of undersea "hot spot" volcanoes in supplying iron tosurface waters, thus linking the solid earth and the biosphere. The team will measure iron abundance,reactivity and nutritional value in buoyant plumes emanating from vents near Heard/McDonald Islands,Australia's only active volcanoes. The project will estimate the hydrothermal contribution to regional biologicalproductivity and extrapolate to the whole Southern Ocean. This will benefit Australia by identifying ironsources that govern productivity and carbon uptake of an economically important ecosystem.

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 oxygen variability since the last glacial maximum (2012 - 2016)$706,046

Description: There is growing evidence for a decrease in ocean oxygen concentrations over the past few decades, but the causes are not understood. This is a problem because small decreases in ocean oxygen content can substantially increase the extent of critically low oxygen zones, leading to decreases in marine biodiversity, loss of ocean fertility and increases in greenhouse gas emissions to the atmosphere, thus amplifying climate change. This project will clarify the links between climate change and ocean oxygen content. Outcomes of this project include a reconstruction of the oxygen content of Southern Ocean waters since the last ice age, understanding changes in oxygen due to physics and biology, and improved oxygen proxies.
