WebObservations show that EAC eddies are prevalent over a broad region of the western Tasman Sea, as far north as 25°S, typically with maximum intensity between 30 and 35°S. At any instant in time the EAC jet is usually evident as a poleward stream adjacent to the continental shelf edge. Other commonly accepted components of the EAC System ... WebThe EAC is the strongest toward the end of Austral summer [Ridgway and Godfrey, 1997; Schiller et al., 2008], when the eddies are spawned from the stronger, more unstable EAC flow (although we acknowledge that there are different views on EAC seasonality and eddy formation [e.g., Wilkin and Zhang, 2007]).
WebMar 1, 2011 · New insights into the Lagrangian and eddy dynamical processes within the East Australian Current (EAC) and the Tasman Sea are presented. We briefly discuss the past campaigns undertaken to observe the EAC and the Tasman Sea eddies as well as the motivation to renew the deployment of drifting buoys into the EAC and the Tasman Sea. Webeddies. Nonetheless, the EAC does generate only a handful of large-scale eddies each year, which have a dominant and persistent in uence over the Tasman Sea circulation and perhaps there is a basis for reintroducing this practice amongst ocean forecasters. Critical to early observational campaigns of the mesoscale were the use of drogued buoys.
Webcyclonic EAC eddies advect warm Coral Sea water southward into the Tasman Sea forming dynamic thermal fronts of several hundred kilometres in length. EAC eddy shelf encroachments induce southward flows that have been observed by Pearce and Boland (1982), to enhance bottom stresses on the mid-shelf with WebThe growth, migration, and detachment of EAC eddies determines the EAC's separation latitude and are a large component of the transport in …
WebThe EAC is weaker than other western boundary currents and is dominated by a series of mesoscale eddies that produce highly variable patterns of current strength and direction. Seasonal, interannual and strong decadal changes are observed in the current, which tend to mask the underlying long-term trends related to greenhouse gas forcing.

North and east of … ipad mail select allThe EAC is a surface current driven by winds over the South Pacific. These winds control how the current behaves at different times of year. The EAC starts on the west edge of the South Pacific Gyre where it collects warm, nutrient-poor water. As it skirts along the east coast of Australia, it carries a large amount of warm tropical water from the Equator southward.
