Meridional fluxes of silica across the Southern Ocean polar front
are attributed to two different processes which generally act in opposite
directions. Equatorward low frequency fluxes of silica inferred from
ISOS current meter data in the Drake Passage are approximately balanced
by poleward meridional diffusion of silica along surfaces of constant
potential density. Considering only these two processes, a balance of
the silicon budget in the Circumpolar Current can be achieved. The
poleward diffusive flux along shoaling density surfaces may uaintain the
high silicon concentrations characteristic of Antarctic surface waters
south of the frontal zone. / Graduation date: 1981
