Biography
Dr Simon Alexander is a Senior Research Scientist at the Australian Antarctic Division. His research interests include Southern Ocean and Antarctic clouds, precipitation and aerosols. Clouds remain one of the key sources of uncertainty for estimating global climate sensitivity. Many climate models have a large surface radiative bias over the Southern Ocean, which is traced back to uncertainties in our understanding of clouds. The clouds and aerosols present over the Southern Ocean are different from those in other regions of the world, due to the pristine nature of the air and minimal anthropogenic aerosol influences. He also has research interests in polar ozone and polar stratospheric clouds, and has contributed as co-author or contributing author to the quadrennial WMO ozone assessment reports since 2014.
Dr Alexander was a leading investigator on recent major international Southern Ocean field campaigns designed to measure properties of clouds and aerosols from air, sea and land. He is currently working with collaborators to analyse these data and use them to improve atmospheric model simulations. More recently, he has contributed to the Year of Polar Predictability (YOPP) Southern Hemisphere winter campaign, with co-ordination of a range of ground-based measurements made from Davis.

Biography
I am a zooplankton taxonomist at the Australian Antarctic Division (AAD) within the Plankton Ecology & Monitoring group, part of the Southern Ocean Ecosystems program.
I commenced full-time work on the Southern Ocean Continuous Plankton Recorder (SO-CPR) program in 1997. As Antarctic plankton are expected to be sensitive and vulnerable to climate change, SO-CPR was established in 1991 by the AAD as a monitoring program on krill and zooplankton. It provides sustained fundamental observations on variation in plankton biodiversity, distribution and abundance to detect and assess potential effects of climate change at the base of the food web. These observations underpin other research for management of the region. SO-CPR is a recognised international monitoring facility, supported by several nations and supports other Antarctic and international monitoring programs.
The overall aim of this research is to provide and maintain a long-term and geographically extensive plankton observing system producing high quality data on plankton biodiversity in order to understand seasonal, annual and long-term ecological changes in the marine ecosystem, and to deliver scientific evidence needed to inform scientists, governments and society of changes into the health and biodiversity of the Southern Ocean.
After graduating from the University of Tasmania with a B.Sc. (Hons.) majoring in Zoology, I was approached by the AAD inviting me to tender for a contract as a fish/krill biologist for a major marine science voyage to Prydz Bay in Antarctica. During the next few years (and a few contracts/voyages) I juggled several biological duties researching krill, fish and finally settling on zooplankton, in particular from the CPR, a role I have performed since 1997.
My current tasks are that of a zooplankton analyst and CPR operations manager within the AAD. This has led to my participation (so far) in 22 expedition voyages to Antarctica and return, mostly aboard the Aurora Australis (19 voyages) and I also have spent 2 major campaigns onboard Polarstern (Germany) as part of international collaboration. Of my voyages, about half have been dedicated marine science expeditions; the remaining I have conducted underway marine sampling onboard resupply cruises.
It is also envisaged that underway plankton sampling (including the CPR) will continue in the Southern Ocean for all voyages on RSV Nuyina once it is commissioned. This long term data set will continue to provide insight into the effects of environmental change on food webs.

In AAPP Delphine will work with modelers and field observationalists to evaluate the role of cryospheric iron sources in fuelling marine productivity around Antarctica.
Biography
Delphine was awarded her PhD in 2006 at Université Libre de Bruxelles upon presentation of a thesis on “The Biogeochemistry of Iron in the Antarctic sea ice Environment”. She was the first to report the high iron concentration in Antarctic pack ice compared to ice free waters, therefore highlighting the role of sea ice as a seasonal ocean fertilizer. She has since produced the large majority of the results on trace metals in sea ice and is unequivocally at the forefront of this research nationally and internationally. Delphine has expanded her interest towards ice shelf – ocean interactions, as well as biogeochemical modelling.
Delphine published over 60 papers in high-ranking peer review journals, 12 as a lead-author. Her articles have received over 4,000 citations, and her h-index is 32 (source: Google Scholar, 15 May 2021). Her publication output provides evidence for the research excellence she has developed on her own as well as through new and ongoing collaborations with top-echelon researchers from the fields of glaciology, marine chemistry, marine biology, analytical chemistry, modeling and atmospheric sciences. Delphine has led several research and Antarctic-based field projects since the end of her PhD.
The awards, fellowships and honors received from her peers within the 5 years following the award of her PhD undoubtedly acknowledge her early commitment to achieve research excellence. She has secured and managed her own funding since her 1st ARC grant in 2008, with back-to-back ARC APD (2008-2011), ARC DECRA (2012-2016) and ARC Future (2020-2024) Fellowships. Delphine’s current ARC Future Fellowship aims at assessing the role of the cryosphere as an ocean fertiliser.
Between 2016 and 2020, Delphine held a lecturing position at IMAS, which also included managerial roles like Graduate Research Coordinator and Deputy Centre Head for Oceans & Cryosphere. She also led AAPP between 2019 and 2020. She is currently the UTAS deputy director for ACEAS (2021-2025).

Biography
I work for the Australian Antarctic Division as the Lead Project Scientist in the Million Year Ice Core (MYIC) Project. The MYIC Project aims to find, drill, analyse and interpret the climate records from Antarctica’s oldest ice and to help to solve major open questions on climate-carbon cycle-cryosphere feedbacks involved in the Earth’s ice age cycles.
The ice age cycles are the defining feature of the past several million years of Earth’s climate history. The scale of transformation of the Earth system across the ice ages is immense: they dominate millennial scale variability in carbon cycling, sea level, ice sheet size and distribution and even human migration and evolution. While there is a consensus that cyclic changes in the Earth’s orbit are involved in forcing the ice ages we still lack an understanding of the feedback processes which amplify such small orbital signals into such profound Earth system changes.
The MYIC will nearly double the age of the existing oldest ice core record, reaching back beyond 1.2 million years ago to a period where the ice age cycles became faster and less intense. The data on climate and environmental conditions preserved in the ice is needed to resolve why this change of pacing occurred and to help answer larger open questions about climate, carbon cycle cryosphere feedbacks. This research contributes to AAPP Theme 2: Antarctica’s influence on climate and sea level.
I received a PhD in ice core Paleoclimatology from the University of Tasmania in 2012. Prior to being appointed to the AAD I held postdoc positions at leading US and European ice core laboratories. The University of Washington and the University of Copenhagen. I have participated in ice core field campaigns in Antarctica, Greenland, the Canadian Rockies and the sub Antarctic islands. I love my job!
I hail from the Great Southern of Western Australia and enjoy going back to the family farm.

About Bea & AAPP Involvement:
Dr Beatriz Peña-Molino joined CSIRO in 2017. She is a physical oceanographer with interests in the large scale dynamics of the ocean and its role in climate. In her work she explores the tropical ocean, through the mid-latitudes, and to the polar systems. Prior to joining CSIRO she completed a PhD in Physical Oceanography from the MIT-WHOI Joint Program (USA). Her work then focused on the western North Atlantic, looking at the interaction between the upper and lower limbs of the Meridional Overturning Circulation. In 2011 Dr Peña-Molino came to Australia and joined the Antarctic Climate and Ecosystems Cooperative Research Centre (ACE CRC), where she worked in problems related to the dynamics of the Antarctic Circumpolar Current and its interaction with topography, formation and export of Antarctic Bottom Water, and ice shelf-ocean interactions in the Antarctic margins. At CSIRO she continues her work in the Southern Ocean but has also become a member of the CSHOR project Indo-Pacific Interbasin Exchange. There she works towards characterizing the different scales of variability in the Indonesian Througflow (ITF). Using both in situ and remote observations she hopes to contribute to our understanding of the forcing mechanisms of the ITF and how the ITF impacts climate both at the regional and global scales.

Biography
At the Bureau of Meteorology, I work in the Science and Innovation Group, Weather and Environmental Prediction Program, where I lead the "Radar Science and Nowcasting" Team. The core of my research is to use radars at different frequencies and on different platforms (ground, ship, aircraft, satellite) to better understand cloud and convection (storms) processes. This better understanding of clouds and convection is then exploited to evaluate and improve satellite products and the representation of clouds and convection in numerical weather prediction and climate models.
In AAPP, my role is to co-lead the Atmospheric component (Theme 1 – Project 1), and my main objectives are to analyse the numerous observations we have collected since 2016 to better understand aerosol-cloud-radiation-precipitation processes and inform the development of improved parameterizations of these processes in the Australian Climate model (ACCESS-CM2).

Biography
My current research that provides the framework for the zooplankton team at AAPP is understanding the functional dynamics of zooplankton in the Southern Ocean, particularly the role of alternative food webs. The best-understood species, Antarctic krill Euphausia superba, occupies a central position in the Southern Ocean ecosystem and is the subject of a fishery. We are examining key phases of its life cycle using the Krill Aquarium at the AAD to measure the effects of increasing CO2 on reproductive output and development of larvae.
Krill's large biomass has resulted in considerable research efforts over many years. However, there are other energy pathways in which krill are not central but instead flow through zooplankton. Alternative pathways could include organisms such as copepods, gelatinous groups and small fish. A fundamental shift in zooplankton communities might already have occurred in the Southern Ocean, whereby krill have declined over the past 30 years, and gelatinous pelagic sea-squirts (salps) have correspondingly increased, as a response to reduced sea ice cover. In my research team we are addressing the role of zooplankton including pteropods, copepods and other euphausiids in the Southern Ocean ecosystem that link primary producers with higher trophic levels.

About Michael & AAPP Involvement:
Michael is an expert geospatial programmer with over 10 years of experience in high level Southern Ocean ecosystem research at the Australian Antarctic Division (AAD). His multifaceted role there as a Research Software Engineer started in the Southern Ocean Ecosystems program and is now consolidated as a cloud-computing and data stream accessibility expert in the Integrated Digital East Antarctica program (IDEA).
"My expertise in problem solving with a wide variety of data types and formats is well recognized, researchers continually turn to me for assistance and I have a broad influence in cross-program and cross-language work. I designed and built our platform raadtools on the Nectar Research Cloud consisting of easy to use functions for a wide collection of data, and which is being re-imagined on cross-language and platform-agnostic basis within the IDEA."
About Michael & AAPP Involvement:
Michael writes software for accessing environmental data and integrating it with ecosystem models, a conduit for modelling approaches in “Links to sea ice and BGC”.

Biography
Dr. Bronte Tilbrook is a biogeochemist based in Hobart, Australia, with CSIRO Oceans and Atmosphere and the Australian Antarctic Partnership Program. He graduated in 1992 with a PhD in chemical oceanography from the University of Hawaii.
Tilbrook leads projects that have established Australia's ocean observing system for the detection of ocean acidification and carbon dioxide uptake and storage, with the research extending from the tropics to the Antarctic shelf. He co-chairs the Global Ocean Acidification Observing Network (GOA-ON), which involves researchers from 100 countries in monitoring ocean acidification and the impacts on marine life. Major efforts within GOA-ON include data exchange, capacity building, mentoring early career and developing country researchers, and building collaborative regional networks. Since 2016 he has been a co-focal point for the Community of Ocean Action for Sustainable Development Goal 14.3 on ocean acidity, a role organised through the Intergovernmental Oceanographic Commission and the Department of Economic and Social Affairs of the United Nations.
Tilbrook is also involved in a number of international programs and working groups on sustained observing to determine trends and changing environmental conditions in the oceans. He is a frequent participant in major conferences and in 2021 is co-chair of the 5th International Symposium on the Oceans in a High CO2 World, Lima, Peru. He has 10730 citations for 90 publications (ISI Web of Science core collection).
