      The Leeuwin current, the intensity of which depends on the Southern Oscillation Index, and westerly winds are the main causes of variation in the level of settlement of rock lobster pueruli off Western Australia, and are therefore indirectly responsible for variations in lobster catches (Pearce & Phillips, ; Caputi & Brown, ).Cited by: 5. The Leeuwin Current is one of the greatest biogeographic influences on Western Australia's marine environments, bringing a flow of tropical water down the coast. The current is strongest and closest to the coast during autumn and winter, in the absence of opposing southerly winds and the associated nearshore northward flowing Cape and Ningaloo.

In International Geophysics, Most ocean modeling, whether global or regional, is done with atmospheric forcing assumed to be known a priori and hence prescribable independently. For hindcasts (simulations of past events, for which atmospheric data are available), certain process studies, and climatological type simulations, this does not prove to.

Introduction. The dominant ocean current along Western Australia (WA) is the Leeuwin Current (LC) (Godfrey and Ridgway,Smith et al., ), a warm poleward flow of tropical other eastern boundary currents (e.g., the Benguela and Humboldt Currents at similar latitudes), the poleward flow of the LC suppresses the persistent upwelling of cool, Cited by: This reference work is available as a limited print edition and online via ScienceDirect.

The online version of this reference work provides the breadth and depth of content Elsevier is known for and also offers a great deal more when it comes to flexibility. Leeuwin Current Water (LCW) and Sub-Tropical Surface Water (STSW) were distinguished and a prominent front at ∼30°S characterized by strong eastward flow separated them.

Although zooplankton abundance increased towards the north, the prey field was unevenly distributed with patches of higher prey concentration associated mainly with by: We study the development and evolution of buoyant river plumes on the continental shelf.

Our calculations are based on three‐dimensional numerical simulations, where the river runoff is introduced as a volume of zero salinity water in the continuity equation and mixing is provided by the model's turbulence closure scheme and wind forcing.

Paleoceanographic (paleocean) modeling is the application of analytic or numerical techniques to predict and understand the ocean’s past circulation, biogeochemical interactions, and climate. Paleocean modeling is primarily a tool for exploring the mechanistic functioning of the ocean and for making concrete predictions testable against.

Forcing Mechanisms Predictive capability is usually premised on the identification and understanding of the mechanisms that couple response to forcing. The preceding section has illustrated that the coastal ocean is subjected to forcing over a broad range of periods, ranging from interannual variations in the coupled ocean-atmosphere system.

As an initial phase of this project we have taken the southeast region of the Australian seabed as our study area. The seabed responses to current climate and possible future climatic conditions over the next 50 yr have been simulated for the first time by a state-of-the-art numerical.

In this study we present a multiproxy data set spanning the Early to Late Pliocene (~ to Ma) from International Ocean Discovery Program (IODP) Expedition Site U (Gallagher et al., ), situated on the Australian northwest shelf (NWS) within the path of the Leeuwin Current (LC), and directly influenced by the ITF (D'Adamo et Cited by: 5.

New and expanded sections include microbial ecology, high latitude systems and the. The LC is a poleward eastern boundary current driven by an alongshore pressure gradient, generated through the transport of warmer, lower salinity water into the tropical Indian Ocean by the Indonesian Throughflow [9,10,11].It is augmented with contributions from the central South Indian Counter Current (SICC) and the Holloway Current in the shelf region around 20°–23° S.

The tidal current was quite strong in the study area. The current speeds ranged from to m/s during the spring tide, which increased landward and had the spatial pattern with stronger.

Along the Leeuwin Current's pathway we find a mean poleward transport of Sv in which the tropical sources account for % of the transport. An extensive survey of the Leeuwin Current system collected plankton samples using µm nets (down to m depth) over shelf ( m), Leeuwin Current ( m) and oceanic ( m) stations from 22°S to 34°S.

Sampling was conducted in May to coincide with peak Leeuwin Current flow and biological activity. We found that the thermal forcing of the Tropical Indian Ocean and Tropical Western Pacific warming are the underlie mechanisms, which were both verified by numerical sensitivity experiments.

Especially, we found the Northern Australia was cooling in contrast to the rapid warming climate, which is an example of independence of the regional. Ezer T. Thattai B. Kjerfve and W.

La Niña events often result in a strengthened LC, high coastal sea levels and unusually warm sea surface temperatures (SSTs), termed Ningaloo Niño. The problem is sufficiently complex that analytic or numerical approaches are necessary to estimate current hazards and explore potential future changes.
