- Abstract:
- Fossil fuel consumption is leading to higher atmospheric CO2 levels and corresponding increases in the concentration of CO2 in seawater (hereafter referred to as CO2aq). There is strong evidence that this increase in CO2aq will change the species composition of the phytoplankton community and the way in which organic carbon is cycled in the sea. One of the key species that will determine how the ocean carbon cycle responds to increasing CO2aq is the coccolithophorid Emiliania huxleyi. Extensive E. huxleyi blooms can be detected by satellite, and it is one of the few organisms for which it is well documented that growth rate is limited by inorganic carbon at ambient CO2aq levels. E. huxleyi affects the ocean carbon cycle in two ways. First, it consumes CO2 to produce organic carbon via photosynthesis. Second, it precipitates calcium carbonate, which releases CO2. Making predictions about the impact of rising CO2aq on growth and calcification by E. huxleyi is complicated by potential interactions with light- limitation, nutrient limitation and temperature. We propose to undertake controlled laboratory experiments to establish the biochemical and molecular biological basis for interaction of changing CO2aq with these other limiting factors, and to incorporate our findings into a conceptual model of growth and calcification by this organism.
