PurposeResearch
Objectives1. To measure the rate of gas transfer across the sea surface as a function of wind and sea conditions by the release of volatile tracers into the water column.
2. To investigate rates of dispersion and advection due to tidal and residual currents by means of the same tracer release.
3. To investigate the biological sources of oxygen, carbon dioxide, methane and dimethyl sulphide in the coherent body of water marked by the tracers, with a view to obtaining budgets of these gases.
