Research Interests

The unifying theme in my work is carbon cycling. As a paleoceanographer, I am investigating circulation in the Southern Ocean to determine how this traps and releases CO2 from the deep ocean on glacial time scales. I also investigate past sea surface temperature changes in the oceans around New Zealand and Australia. On shorter timescales, I am investigating sources, pathways, and sinks of both terrestrial and marine carbon in modern environments with an eye to their interaction with coastal ocean acidification. To do this, I employ isotopic (δ13C, δ18O, and 14C) and organic (biomarker, Uk37) geochemical techniques to answer these questions of sea surface temperature and global circulation change.
