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.

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.

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.

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.

Greenhouse gases are rapidly increasing in the modern atmosphere, causing substantial global warming. To put the modern changes in context, we need to know how greenhouse gases varied prior to industrialization and what processes controlled them. As an AAPP Ice Cores Research Associate, Andy measures stable isotopes of carbon dioxide and nitrous oxide in ice core air bubbles. Combined with modelling, the data quantify variations in the past and constrain the processes that were responsible.

Antarctic krill play an important role in Southern Ocean ecosystems, as a key component of the marine food web with an enormous circumpolar biomass. Krill are vulnerable to changes in their surrounding environment which is predicted to shift in future years. My research focuses on the present drivers of krill distributions and how future environmental changes may influence this, with flow-on effects to the surrounding ecosystem. My research uses novel bioacoustic tools, experiments and field observations collected from recent AAPP research voyages (including the recent Trends in Euphausiids off Mawson, Predators and Oceanography voyage) to explore these drivers.

Biography
In 2017, I graduated with a Bachelor of Marine and Antarctic Science (with Honours) from the University of Tasmania. My undergraduate research provided me with experience in phytoplankton identification through the gut contents analysis of numerous Southern Ocean krill species.
I undertook a PhD with the Institute for Marine and Antarctic Studies, researching the distribution and bioavailability of iron (a key limiting nutrient) in Antarctic coastal environments. This work also explored the biogeochemical role of marine animals such as krill and baleen whales in recycling iron to productive coastlines. Throughout my PhD, I gained skills in trace metal sampling and analytical techniques, as well as multidisciplinary environmental spatial analyses.
Through my Southern Ocean field work, I have been involved in numerous scientific teams and disciplines including polar zooplankton ecology (KARE-21 voyage), trace element biogeochemistry (ENRICH voyage) and more recently acoustic fisheries science (TEMPO voyage). My overarching interest in Southern Ocean ecosystems, their environmental drivers, and impacts of climate change on these systems has fuelled my research to date.

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.

Current AAPP Activities:
Tessa's AAPP role is developing ice core records of climate for the southwest Pacific and southern Indian Ocean from ice core archives. The ice cores have been drilled in regions of East Antarctica that border the southern Indian and Pacific Oceans, both of which have very few long meteorological records. These palaeoclimate records aid in extending and quantifying the climate and weather variability stemming from this region. In addition, she collaborates closely with hydrologists and water resources managers to use these long records to better assess hydroclimate risks for Australia.

Biography
I knew I wanted to be an ocean expert from a young age, having been captivated each summer by bioluminescence while exploring the rugged coastal regions of Vancouver Island. I experimented with a myriad of marine-related interests, including volunteer roles assisting with a local salmon enhancement project, nesting sea turtle data collection, seagrass rehabilitation, as well as public engagement with Project Seahorse. My interest in food webs began during a summer spent at the remote Bamfield Marine Sciences Centre where I researched feeding preferences of marine snails, which then progressed to exploring trophic interactions between harvestable and wild species within and adjacent to an integrated multi-trophic aquaculture facility for my master’s degree at the University of Victoria. My foray to marine zooplankton research began while working for the Canadian Department of Fisheries and Oceans at the Maurice Lamontagne Institute in Mont Joli, Québec, where I participated in expeditions around the Gulf of Saint Lawrence as part of a long term research project estimating changes in zooplankton abundance and biomass due to changing climate. It was during this time that I also realised my interest in image analyses of microscopic specimens, having spent many hours measuring carapace lengths of amphipods.

These tools will then be used to evaluate how changes in sea-ice nutrients, iron, and organic matter are likely to impact the Southern Ocean biogeochemistry and carbon cycle in the future. I will also provide a leadership role in combining process studies and laboratory experiments to identify key drivers of ice algal productivity in East Antarctic sea ice.
