Biography

I finished my 4 year Masters in Oceanography at the NOC, Southampton in 2010 before working briefly as a research assistant, looking at the impacts future ocean acidification and investigating coccolithophore calicification in the Bay of Biscay.

After a year of cycle touring I moved to Norwich to work as Carbon Observations Coordinator in the European project Carbochange, helping to improve measurements of surface ocean carbon dioxide from commercial ships. I also researched the change in anthropogenic carbon in water masses of the subtropical North Atlantic. I started my PhD at the UEA in October 2013.

Key Research Interests

I am interested in marine biogeochemistry, in particular the way in which the oceans take up, store and transport carbon, and the connections between the marine carbon cycle and climate.

My PhD

I am investigating the mechanisms of carbon uptake by the Southern Ocean through measurements of the carbonate system in the region.

The uptake of carbon dioxide by the high latitude Southern Ocean remains poorly understood, largely due to a lack of observations. I am using a unique, 3 year time series of dissolved inorganic carbon and total alkalinity from Rothera on the West Antarctic Peninsula to try to clarify the mechanisms behind the seasonal cycle of inorganic carbon in seasonally ice covered waters. A better understanding of seasonal and interannual variability will hopefully provide clues about past and future interactions between climate and the carbon cycle.

I have also participated in a research cruise in the Drake Passage, Weddell Sea and Scotia Sea, during which I sampled for dissolved inorganic carbon, alkalinity, inorganic nutrients and dissolved oxygen. I will use this dataset to investigate transport and storage of natural and anthropogenic carbon by water masses of the Southern Ocean.
