Biography
Dr Sue Cook is a glaciologist and co-project leader for Australian Antarctic Program Partnership Project 3: Ice Shelves. This project aims to identify ocean-driven and cryosphere-driven mass loss from East Antarctic ice shelves, and their susceptibility to changes in climate forcing. Her research involves the study of dynamic processes on ice shelves using a wide range of techniques from numerical modelling to field observation and satellite remote sensing.
Sue joined UTAS in 2015 working as a glaciologist for the Antarctic Climate & Ecosystems CRC. During her time at UTAS she has worked on developing new models of icebergs calving, participated in multiple Antarctic field seasons, and contributed to teaching Antarctic science at UTAS. Prior to arriving in Tasmania she completed her PhD at Swansea University, on the topic of environmental controls on iceberg calving from tidewater glaciers. She then worked for two years as a postdoctoral researcher at the University Centre in Svalbard where she continued her research into iceberg calving processes.

Current AAPP Activities:
The Southern Ocean is at the centre of the global ocean. It plays a key role in regulating the exchange of heat and salt between the surface ocean and the abyss, and the transport of heat to Antarctic ice shelves. This exchange is driven by both ocean currents and sea ice. In recent years, we have witnessed dramatic reductions in the amount of sea ice that forms around Antarctica. My research uses numerical models and theory to improve our understanding of the ocean around Antarctica and its role in global climate.

Climate and weather simulations suffer from significant radiation biases over the Southern Ocean, with implications for the global energy balance and multiple aspects of the earth system. As a part of Sonya’s work with the AAPP, she will address the radiation bias in the Australian climate and weather model ACCESS, with a focus on how aerosols affect cloud properties. To do this, she will utilise the growing volume of Southern Ocean atmospheric observations to challenge the model, and identify the underlying processes that need to be improved.

Current AAPP Activities:
The circulation of the Southern Ocean has an outsized role in global climate by controlling how heat makes its way towards the Antarctic continent and how much anthropogenic heat and carbon are stored away in the abyssal ocean. Annie’s work with the AAPP focuses on two major themes: the influence of eddies on the Southern Ocean and the drivers of water-mass changes. Using a suite of observational data, Annie seeks to better understand the mechanisms for transporting heat across the Southern Ocean, where and how those warm waters get onto the Antarctic continental shelf, and what is responsible for changes in the deepest, densest waters in the ocean.

Biography
My first foray into Antarctic science occurred in 2006 where I undertook a research project on Antarctic polar stratospheric cloud detection and property retrieval, working under the guidance of Dr Andrew Klekociuk (Australian Antarctic Division). I graduated from my Ph.D. (University of Tasmania) in 2011, working with Dr Rob Massom on the remote sensing and analysis of East Antarctic landfast sea ice distribution and variability. This was followed by a postdoctoral appointment working on remote sensing of the Antarctic continent, with a focus on parameter retrieval from parameterisation and analysis of microwave backscatter. I then completed a two year postdoctoral fellowship in Japan (Hokkaido University, working with Prof. Kay Ohshima) working on circumpolar, high-resolution mapping of Antarctic landfast ice, with a particular focus on its interaction with sea ice production in coastal polynyas. I returned to Tasmania in 2015 to continue work on landfast sea ice remote sensing, and also developed interests in microwave remote sensing of the Antarctic sea ice, with particular applications toward remote sensing of the marginal ice zone (defined by wave-ice interaction) and sea ice thickness retrieval.

Current AAPP Activities:
Will's current research focusses on how the ocean acts as a connection between Antarctic sea ice and the global climate system. This covers two broad topics:
- The role that the ocean plays on Antarctic sea ice variability and response to anthropogenic climate change, i.e. how the ocean affects sea ice
- The role that Antarctic sea ice plays in driving the Southern Ocean, and in particular the ocean’s uptake of anthropogenic heat and carbon.
Will works with both observations and climate/ocean models. The nature of his current research, and the lack of year-round sub-surface ocean observations on the Antarctic continental shelf, means that his AAPP research primarily uses ocean-sea ice model experiments.

Biography
Will gained his PhD in 2009 from the University of California, Los Angeles (UCLA), where he studied the role of the atmosphere in driving large-scale variability of Southern Ocean sea ice. Following his PhD, Will was a post-doctoral researcher in the Ocean Circulation group at the NASA/Caltech Jet Propulsion Laboratory. His work at JPL involved combing satellite data with Argo float data to estimate the strength and heat transport of the Atlantic Meridional Overturning Circulation (AMOC). This ground-breaking time series is regularly updated and is widely used in the AMOC community. He came to Hobart in 2012 to take up a position in Ocean Detection and Attribution with the Institute for Marine and Antarctic Studies (IMAS), before moving to the Antarctic Climate and Ecosystems Cooperative Research Centre in March 2015, where he worked on Southern Ocean change until ACE CRC’s completion in 2019.
Over that period, his expertise on Antarctic sea ice change and variability was sought by the US National Academy of Sciences, and the Commission for Conservation of Antarctic Marine Living Resources (CCAMMLR).

Elements such as iron are essential for the growth of phytoplankton in the ocean, but in the Southern Ocean these elements are present in such low concentrations that they limit the growth of phytoplankton. The Southern Ocean is the largest of these regions and plays a key role in climate regulation but remains relatively understudied. Tom examines trace element biogeochemistry in the Southern Ocean by identifying the sources, sinks and biological cycling of iron (and fingerprint trace metals) as the controlling element of Southern Ocean productivity.

Tom is a trace element biogeochemist who researches the sources, sinks and cycling of iron and other trace elements in the ocean. He aims to improve our current understanding of what currently drives or limits the productivity of primary producers in the ocean so that we may better predict how these processes may change under future changing climate conditions.
Previously, Tom completed a postdoc at the University of Washington, USA, measuring the impact of episodic glacial dust trace element inputs from glacial valleys into the Gulf of Alaska. He completed a PhD at IMAS, focused on the impact of volcanism on trace metal biogeochemistry in the Southern Ocean.

Biography
I studied a Bachelor of Applied Science (Physics) at the Queensland University of Technology. I continued at QUT and completed a PhD in atmospheric science, investigating the role of aerosol emissions as cloud condensation nuclei over the Great Barrier Reef and from fires in northern Australia.
After this I moved to France for just over two years and worked in two laboratories as a postdoctoral scientist in association with the French National Centre for Scientific Research and the French National Centre for Spatial Studies. Over those two years I investigated atmospheric aerosols and their transport in the Arctic, the Mediterranean and the southeast Atlantic and southern Africa.
Upon returning to Australia in 2019, I worked briefly for the Defence Science and Technology Group evaluating the performance of low-cost air quality sensors before taking up my current role as an atmospheric scientist within the AAPP at IMAS and the University of Tasmania. My main interest now is investigating aerosol-cloud-radiation interactions over the Southern Ocean.

Current AAPP Activities:
The ocean’s ability to sequester carbon away from the atmosphere exerts an important control on global climate. However, our conceptual understanding of how nutrients and carbon are cycled in the ocean at present is incomplete. My research goal is to understand the biological, chemical and physical processes that influence current and future patterns of phytoplankton production and carbon export, and the flow-on effects to ocean productivity. Quantifying where iron and carbon are stored, in what form, and the fluxes between these reservoirs, are vital for understanding climate-driven impacts at present and predicting future changes.
My current role covers two areas:
- What are the effects of eddy-driven subduction on carbon export?
- Can the southward movement of the sub-tropical front provide an analogue to future ocean warming and what are the implications for carbon export?
I was also recently awarded an ARC Discovery Project to examine how zooplankton shape the response of ocean productivity in a changing climate.

Biography
My PhD research focussed on the recycling of iron by marine animals in the Southern Ocean. Following my graduation in 2017, I undertook a 1-year postdoctoral fellowship in microbial ecology and carbon export around marginal ice zones in Australia, followed by a 3-month SCAR Fellowship in France. I then undertook a ~3-year postdoctoral fellowship in biogeochemical modelling in the UK. Over the COVID period, I transitioned to a 2-year science management role as the program lead for the Biology and Ecosystems panel of the Global Ocean Observing System (GOOS), IOC-UNESCO followed by a 6-month maternity cover for the Southern Ocean Observing System. I returned to full-time research in May 2023 as a carbon biogeochemist with the Australian Antarctic Program Partnership.

Biography
I am broadly interested in biogeochemistry and carbon cycling spanning scales from the interaction between phytoplankton and eddies at the mesoscale to changes in net primary production following global scale climate disturbances. While my work focuses on the underlying mechanisms that regulate marine productivity I am also very interested in the broader societal implications of oceanic carbon cycling amidst a changing climate.
I first learned how to leverage my engineering education to tackle broad questions in biogeochemistry as an undergraduate at Duke University. Backed by competitive financial support, awarded as a Pratt Research Fellowship, I modelled rainfall variability and seasonal carbon cycling to help inform land-use management in drought prone regions. After graduating with departmental distinction I secured external competitive funding in the form of an NDSEG Fellowship to pursue my Ph.D. in the MIT/WHOI Joint Program.
During graduate school I began to investigate how vertical mixing controls phytoplankton bloom phenology in the Southern Ocean, from both a bottom-up and top-down perspective. I found strong evidence in a Community Earth System Model simulation, and implicit support in the remote sensing record, that blooms can initiate amidst both strong and weak cell division rates depending on iron and light availability, and trophic decoupling.
During the later half of my doctorate, my research shifted to the explicit role of mesoscale eddies in driving phytoplankton ecosystem dynamics. From a bottom-up perspective, I found that Eddy-induced Ekman pumping is the dominant iron transport mechanism in simulated eddies, and in turn is the primary driver of eddy modified division rates throughout most of the year. One exception occurs in deep winter mixing periods when eddy modified light availability instead dominates. The ultimate effect on anomalous biomass, however, is complicated by other physical and biological pathways, resulting in striking seasonal and regional variability in the direction of anomalies and mechanisms that drive them.
After completing my doctorate I continued to work as an independent researcher to help investigate how a global nuclear conflict, and subsequent changes to oceanic light and nutrient availability, would effect marine biogeochemistry and productivity.
Finally, throughout my career I have sought place my work in a broader societal and political context. To this end, I have completed a fellowship at the US Department of Energy working at the intersection of ocean policy, renewable energy, ocean observing systems; co-chaired the 2015 Graduate Climate Conference; completed a graduate Certificate in Science Technology and Policy at MIT; published a policy paper on Ocean Iron Fertilization; and attended various ocean policy conferences and workshops.

Biography
I received a PhD in Botany and Oceanography in 2003 from the University of British Columbia, Vancouver, Canada and a BSc in Biology (Major in Marine Biology) from McGill University, Montréal, Canada. I worked as a postdoctoral researcher at the University of Otago, Dunedin, New Zealand (2001-2011), and as a Research Fellow at the Research School of Earth Sciences at the Australian National University (2012-2016). I have worked at IMAS since 2016.
As a quantitative phytoplankton ecophysiologist, I couple trace metal clean environmental manipulation laboratory studies with ocean-going voyages to address fundamental questions in phytoplankton physiology and ecology and aspects of ocean biogeochemistry, such as the adaptations of Southern Ocean phytoplankton to the particular constraints imposed by their environment, the role of the marine biota in the cycling of major nutrients and trace metals in the Southern Ocean, and the physiological responses of Southern Ocean phytoplankton to projected changes in their climate.
In the lab, my colleagues and I provided the first biochemical explanation for the lower iron requirements of oceanic diatoms compared to their coastal cousins (Strzepek and Harrison 2004) and that Southern Ocean phytoplankton species, in particular, have converged on a similar evolutionary strategy whereby they need much less iron for photosynthesis than phytoplankton from warmer waters (Strzepek et al. 2011, 2012). A subsequent detailed biochemical analysis published in PNAS (Strzepek et al. 2019) provided a mechanistic explanation for the combined effects of iron, light and temperature in shaping this evolutionary trajectory. I am currently working with modellers to incorporate these novel photophysiological responses into biogeochemical models and in the future trait-based ecosystem models, and conducting further laboratory manipulation experiments (temperature/iron/light) to couple physiological and whole cell protein expression responses.
In parallel with my laboratory work, I routinely go on research voyages to quantify particular aspects of phytoplankton ecology and biogeochemistry, such as the environmental forcings on the marine biogeochemical cycles of carbon and iron.

Biography
I am a research scientist and educator specialising in glaciology, satellite remote sensing and applied geophysics. Broadly my research focuses on identifying and investigating the hazards associated with glaciers, ice sheets and snowpacks in a changing climate. Particularly in developing and adapting geophysical approaches to allow the prediction of hazards in the natural environments, and the assessment of risk to society on a global and local scale.
I completed my PhD at the University of Swansea in 2012, focusing on early recognition and mitigation of glacial lake outburst hazards in the Himalayas. Since then I have had the opportunity to work as a post-doctoral researcher at ETH in Switzerland, the University of Innsbruck in Austria and attained two post-doctoral research fellowships to work at the University Centre in Svalbard and Swansea University. I have been working at the Institute of Marine and Antarctic Studies in Hobart since January 2019, focusing on developing remote and field-based techniques applied to glacier crevasse detection for scientific and field safety applications.
In my professional life I have been fortunate enough to gain significant experience living and operating in remote, logistically difficult and high-altitude environments. Having participated in, and organised extensive fieldwork in Svalbard, the European Alps the Himalayas, and most recently three summer seasons in East Antarctica with the Australian Antarctic Division.

Biography
I’m an early-career researcher during a period of major technological and scientific advances in the field of satellite altimetry. In November-December 2023, I participated in my first oceanographic voyage, the FOCUS voyage on Australian CSIRO research vessel RV Investigator (part of the SWOT-AdAC campaign). For the first time, I experienced first-hand how oceanographic data is collected and making observations with ship-borne instruments, in particular, being part of a team sampling a large number of CTD rosettes (a total of 111 CTD casts in one five-week voyage). After years of processing data, it was exciting to ‘feel the physics’ of the ocean in a high-energy zone of the Antarctic Circumpolar Current. This greatly helps my understanding in using data and modelling frameworks. I appreciate how the SWOT-AdaC campaign is bringing ocean physics to life.
I am with the Australian Antarctic Program Partnership as a Research Associate until 2026. In my new-found relationship with the Southern Ocean, I am discovering different types of physics. Surrounded by brilliant scientists and technicians and wonderful technology, I am both absorbing new fields and infusing them with my own training. Against a background of dramatic change and exposed to constant data flow, I want to put things together in an integrated and open way. By helping to fill the gaps in the complex story of the role of the Southern Ocean in the global climate system, I hope to make meaningful contributions to climate-related research into poleward heat transport to Antarctic ice shelves.
