A numerical simulation of the East Australian Current (EAC) has been used to investigate the nutrification of shelf waters at Jervis Bay, south-eastern Australia, prior to the massive coccolithophorid bloom that was first observed on 16 December 1992. The simulation suggests that a small cold-core eddy developed between the continental slope at Jervis Bay and the EAC jet further offshore during 7 and 14 December 1992. This unstable cold-core eddy is likely to have uplifted cold, nutrient-rich water onto the Jervis Bay shelf, and this upwelling, in combination with upwelling-favourable winds, probably transported nutrients from the deep ocean to the entrance of the bay.

The presence and movement of Bass Strait Water along the continental slope of south-eastern Australia during the Australian Coastal Experiment (ACE) is estimated by evaluating the amount of salt and heat imported from Bass Strait for the five standard hydrographic ACE sections. South of Jervis Bay (35°S), the amounts decrease from September 1983 to February 1984 by a factor of two. North of Jervis Bay, the amounts depend strongly on the position of the East Australian Current and its eddies. It appears that during periods of low eddy activity Bass Strait Water can be carried northward well past Newcastle (33�S).
