| 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. |
