Processes (N to S)

• Deep water transport• Congo river plume inputs• Angola Dome• OMZ – redox cycling • Upwelling and productivity• Margin-basin transport• Agulhas eddy transport • Dust inputs

Rationale

• Sample along 5oE (A13 track): major water masses, deep basins – continue south to sample Cape Basin at southern end

• Shorter zonal transects (A7, A8 and into Benguela upwelling) orthogonal to sample major features and provide 3D framework

• Summer (Jan-May) sampling to capture maximum upwelling and Angola Dome feature

In Addition

• Sample fluxes through Romanche FZ: meridional transects to be done on major N-S sections or “AMT” type resupply legs

• Amazon to Congo transect: riverine, equatorial and oligotrophic regimes, dust inputs

To Discuss

• Station spacings

• Casts per station

• Sediment sampling (boomerang free-fall core top sampler)

• Who does what
