The cool-water temperate carbonate depositional realm is neither as well documented nor as well understood as the more familiar warm water tropical domain (Nelson, 1988; James, 1997). This is largely because these sediments, formed and deposited in waters <20°C, occur in inhospitable environments that are difficult to study. Apart from southern Australia, New Zealand, and the peri-Mediterranean region, the Cenozoic record of these deposits is meager and most are buried in the subsurface. Leg 182 sites provided the opportunity for new insights into the spatial and temporal aspects of temperate carbonate deposition in shelf edge and upper slope environments.
Nine sites were drilled during Leg 182 in the western Great Australian Bight (GAB) (Fig. F1), extending from the shelf edge (203 m water depth) to the middle continental rise (3874 m water depth) (Hine et al., 1999; Feary, Hine, Malone, et al., 2000). The shallower sites were distributed between two shelf edge to upper slope transects, forming eastern (Sites 1127, 1129, and 1131) and western (Sites 1130 and 1132) transects (Fig. F1). The primary drilling objective for the leg was a more detailed understanding of global environmental change in high- to mid-latitude settings. Within this broad overall objective were a number of primary aims:
