  1. Hutchins et al. (2007) Trichodesmium cultures grown under different CO2 and temperatures Meta analysis (Findlay et al. 2011) on E. huxleyi cultures shows that after pCO2 and TA, P concentration controls PIC:POC response

  2. Fv/Fm decreases slightly in continuous light cultures – stress?

  3. 14h daylight period: calcification maintained, but at the cost of growth rate 24h daylight period: no change in growth rate, but cultures produce excess coccolithes

  4. Shipboard experiments from the Arctic Circle and Southern Ocean Meta-analysis of all OA literature to see whether or not L:D controls the observed response

  5. Discrepencies in OA response can be explained by L:D cycle L:D cycle is an important consideration for OA experiments Local changes in L:D cycles in nature as climate changes

  6. Acknowledgements Supervisors Dave Suggett and Tracy Lawson Richard Geider the Algal Research Group at University of Essex Mark Moore and Alex Poulton I am in the third year of my PhD and looking for more research opportunities! lmjbre@essex.ac.uk
