Dr Klaus Meiners: MSc, PhD

Research interests

I am a sea ice ecologist working with the Antarctic Climate Program of the Australian Antarctic Division. My research is directed at understanding the impacts of changing sea-ice conditions on Antarctic marine ecosystems and Southern Ocean biogeochemical cycles. I am particularly interested in cross-disciplinary science that underpins mechanistic understanding of coupled physical-biological processes in the Antarctic sea-ice zone. My current work focusses on understanding physical drivers of ice-associated algal production and the importance of sea ice as habitat for Antarctic krill, a key species in many Southern Ocean food webs. I am using Remotely Operated Vehicles (ROVs) and optical methods to investigate ice algal distribution and under-ice habitats. These novel methods allow concomitant measurements of sea-ice physical and biological properties at scales that are relevant to inform the development and evaluation of sea-ice ecosystem models.

I started studying sea ice ecosystems in the late 90’s, initially working in the Arctic conducting fieldwork for my PhD at Kiel University (Germany) and a postdoctoral fellowship at Yale University (USA). I moved to Tasmania in 2005 to work at the Antarctic Climate and Ecosystems Cooperative Research Centre and started working for the Australian Antarctic Division in 2010. In total I have spent well over 2 years working on ice-breaking vessels and in remote field camps, and had the privilege to work with terrific teams of ship and stations crews, and fellow expeditioners and scientists.
