Description
Description: School of the Environment, Flinders University, Adelaide, Australia. Analyses of >10 years of satellite-derived ocean-color data reveal the existence of a highly productive ecosystem on the west Tasmanian shelf. A closer event-based analysis indicates that the nutrient supply for this system has two different dynamical origins: (a) wind-driven coastal upwelling and (b) river plumes. During austral summer months, the west Tasmanian shelf forms a previously unknown upwelling center of the Great South Australian Coastal Upwelling System, presumably injecting nutrient-rich water into western Bass Strait. Surprisingly, river discharges render the study region productive during other seasons of the year, except when nutrient-poor water of the South Australian Current reaches the region. Overall, the west Tasmanian shelf is more phytoplankton-productive than the long-known coastal upwelling along the Bonney Coast. The existence of phytoplankton blooms during the off-upwelling-season may explain the wintertime spawing aggregations of the blue grenadier (Macruronus novaezelandiae) and the associated regionally high abundance of Australian fur seals (Arctocephalus pusillus doriferus).
