determination of physics (ADCP, temperature, buoy drift, SF6)
and biogeochemistry (nutrients, Chl a, AFC) will enable
quantification of upwelling and filament dispersion, and
determination of horizontal and vertical diffusivity, shear and
volume transport. Co-ordinated measurements of N2O, pCO2,
CH4, DMS, O2, CO and iodocarbons with
transfer velocity measurements (3He) will constrain
regional air-sea fluxes and offshore transport. Filament strength
and periodicity will be determined using MODIS remote sensing.
Stable isotopic characterisation of N2O and CH4
will quantify the upwelling source of these gases.
