Planned Impact

see main proposal
Description Project at early stage. We have established molar extinction coefficients of metal creso purple (MCP) for a range of high (>40) salinities and low temperatures (<0C). The next step will be to establish the acid dissociation constant for MCP at enhanced salinities and low temperatures. This work is currently finalised.
Exploitation Route The data coming from this project will be crucial for calculations of the carbonate system in polar waters. It will consequently influence IPCC projections.
