We are interested in the gases produced by organisms in the mesocosm and how they will flux between the ocean and the atmosphere. Many of the gases are important for climate regulation. The major gases we are interested in are:
Dimethyl Sulphide (DMS, and DMSP and DMSO) – this is produced by phytoplankton and has an important role in cloud formation.
Oxygen – Phytoplankton release oxygen during photosynthesis, but other organisms respire and take up oxygen. We are interested to know if different levels of carbon dioxide will affect the cycling of oxygen.
