MARCHEMSPEC - Chemical Speciation Modelling in Seawater to meet 21st Century Needs

Chemical speciation, the distribution between different chemical forms of an element in seawater, plays a key role in determining the element’s properties as nutrient or toxin to marine life.

It is therefore important to understand the way in which chemical speciation responds to global change processes including ocean acidification and warming. Many aspects of chemical speciation that cannot be measured directly can be calculated if the necessary thermodynamic information is available.

The aim of this project is to develop versatile software to enable non-specialist users to carry out their own chemical speciation calculations using start of the art methods, and with full documentation for the thmerodynamic data used. No such software currently exists. The software will be made freely available to the scientific community.
