Research interests

I have been studying sea ice ecosystems since 1996 when I studied biological oceanography at Kiel University in Germany. Initially I worked primarily in the Arctic, completing my MSc (1999) and PhD (2002) on sea ice microbial ecology and sea ice algal community structure and function, respectively. After completing my PhD I worked as Donnelley Environmental postdoctoral fellow at the Department of Geology and Geophysics at Yale University (USA). During this time I investigated the role of ice algal mucus and exopolymer substances on sea ice habitability.

I moved to Tasmania in 2005 to work at the Antarctic Climate and Ecosystems Cooperative Research Centre (ACE CRC) in Hobart, where I worked in the ‘Ecosystems’ program, investigating processes at the interface of sea ice physics, biogeochemistry and ecology. I started using Remotely Operated Vehicles (ROVs) and optical methods to investigate ice algal distribution and the under-ice habitat. Since 2010 I have been working as a research scientist in the Australian Antarctic Division’s Climate Processes and Change program (and the former ACE CRC’s Ecosystem Impacts program).

My current research interests include:

  • Large-scale sea ice coupled physical-biological processes: understanding links between physical and biological elements of the Antarctic sea ice zone.
  • Sea-ice ecology and biogeochemistry: nutrient dynamics, dissolved and particulate carbon dynamics, sea ice algal biomass and production measurements to inform the development of sea ice biogeochemical models.
  • Bio-optical methods to measure sea-ice algal biomass on medium scales using Remotely Operated Vehicles

Current projects

    International representation/collaboration

    • Member of the Scientific Committee on Antarctic Research — Antarctic Sea ice Processes, Ecosystems and Climate (ASPECt) expert group.
    • Member of the Scientific Committee on Oceanic Research — Biogeochemical Exchange Processes at the Sea-Ice Interfaces (BEPSII) expert group.
    • My work depends on close collaboration with national and international colleagues including Dr. Gerhard Dieckmann (Alfred Wegener Institute, Germany), Dr. David Thomas (University of Bangor, UK), Dr. Martin Vancoppenolle (CNRS, France), Dr. Rolf Gradinger (University of Alaska, USA), Dr. Delphine Lannuzel (IMAS, Australia) and Dr. Pier van der Merwe (IMAS, Australia).
