Dr Annie Foppert is a CSIRO Postdoctoral Fellow and a member of the Southern Ocean dynamics, circulation and water mass formation project team. Her research primarily focuses on the dynamics of large-scale ocean currents, with the main focus on the Antarctic Circumpolar Current (ACC). Dr Foppert seeks to understand how heat moves poleward across the ACC, what the mechanisms for that heat transport are, and how those governing processes may change in the future. She will address these questions by analysing observational data in combination with output from numerical model simulations.

Dr Laura Herraiz-Borreguero is a Research Scientist at CSIRO and a member of the Southern Ocean observations and change project team. Dr Herraiz-Borreguero received her PhD in physical oceanography in 2009 from the University of Tasmania. Before joining CSIRO in June 2018, Dr Herraiz-Borreguero was a Marie Curie Research Fellow at the University of Southampton, UK. During this time, her research evolved from open ocean/large scale physical processes in the ocean to polar oceanography and Ice shelf-ocean interactions. From 2014 to 2016, Dr Herraiz-Borreguero worked as a postdoctoral researcher at the Centre for Ice and Climate in Copenhagen, Denmark and from 2010 to 2013, she was a Postdoctoral Research Fellow at the Antarctic Climate and Ecosystems CRC in Hobart, Tasmania. She led several papers on the coupling of the ocean with the Amery Ice Shelf, East Antarctica. This work used a unique set of observations from boreholes drilled through the ice shelf by the Australian Antarctic Division’s AMISOR project.

Dr Je-Yuan (Andy) Hsu is a CSIRO Postdoctoral Fellow and a member of the Coupled warm pool dynamics in the Indo-Pacific project team. Dr Hsu received his PhD degree in the School of Oceanography in the University of Washington 2017, studying the dynamics of surface ocean boundary layer induced by the tropical cyclones by using the in-situ measurements of EM-APEX floats. His primary research interests focuses on the atmosphere-wave-ocean coupling dynamics, and field measurements on the upper ocean physics and surface waves.


Dr Andrew Lenton is a member of the Southern Ocean dynamics, circulation and water mass formation project team. He is an ocean carbon cycle modeler in CSIRO’s Climate Science Centre, with extensive experience in modelling the carbon-cycle at different temporal and spatial scales, from individual organism responses through to the Australian Community Climate and Earth System Simulator (ACCESS). Dr Lenton also works closely with observations using them to assess models as well as to use novel observational approaches to advance our understanding of carbon processes. Specifically his current and future research goals focus on key three key impact areas: (i) Quantifying the past, present and future role of the ocean in the global carbon cycle; (ii) Exploring and understanding the impact of the carbon cycle changes on both climate and marine diversity and productivity; (iii) The potential role of geoengineering in mitigating climate change and ocean acidification.

Dr Kewei Lyu joined CSIRO and CSHOR in February 2018 as a Postdoctoral Fellow. His research focuses on the Southern Ocean sea level change and the associated ocean heat uptake and redistribution.



Dr Benjamin Ng is a CSIRO Postdoctoral Fellow working on the ENSO and IOD project. His main research interests include tropical climate dynamics and variability with a primary focus on the IOD. Dr Ng aims to understand how the IOD and its properties respond to greenhouse warming using coupled models and simulations. He is also interested in ENSO and the interaction between tropical basins.


Dr Beatriz Peña-Molino is a member of the Indo-Pacific interbasin exchange project team. 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 deep and the upper limbs of the Meridional Overturning Circulation. In 2011 Dr Peña-Molino came to Australia and joined the Antarctic Climate and Ecosystems Cooperative Research centre, 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. As part of the Indo-Pacific Interbasin Exchange project Dr Peña-Molino is now working 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. When she is not thinking about the ever-changing tropical ocean, Dr. Peña-Molino also continues to explore the role of the Southern Ocean in climate as part of her work.

Dr Océane Richet is a CSIRO Postdoctoral Fellow and a member of the Indo-Pacific interbasin exchange project team. Her scientific interest is the study of ocean processes connected to global oceanic circulation. An example of her recent work was to study the role of internal tides on deep mixing. Dr Richet graduated in December 2017 from École polytechnique, France. The title of her thesis is, ‘Impact of ocean waves on deep waters mixing and large-scale circulation’.


Dr Veronica Tamsitt is a UNSW Postdoctoral Fellow and a member of the Southern Ocean dynamics, circulation and water mass formation project team. Her research combines ocean observations and models to better understand the three-dimensional structure of the Southern Ocean overturning circulation and its role in climate. As a member of the CSHOR team Dr Tamsitt will be working with state-of-the-art climate models and novel ocean observations to investigate different aspects of the Southern Ocean circulation. In particular, she will be using model analyses and Lagrangian particle tracking to better understand the underlying dynamics of upwelling hotspots associated with undersea topography and mapping the pathways of upwelling Circumpolar Deep Water to the Antarctic continental shelf.

Dr Steven Phipps is an ice sheet modeller, climate system modeller and palaeoclimatologist, based within the Institute for Marine and Antarctic Studies at the University of Tasmania in Hobart. His research aims to understand past changes in Antarctica and the climate of the Southern Hemisphere, particularly during the period from the Last Glacial Maximum (around 21,000 years ago) to present. To approach this problem, he uses a combination of ice sheet models, climate system models and natural archives, such as ice cores, tree rings and corals. His core research interests are: past changes in the Antarctic ice sheet, including its contribution towards changes in global sea level; past climate variability and change in the Southern Hemisphere; and techniques for integrating numerical models with data from natural archives. Dr Phipps contributes to the Southern Ocean sea level change project.
