Figure 2. Map showing location of Leg 194 proposed primary sites (black circles), contingency sites (black squares), and Sites 815 and 816 from Leg 133 (black-rimmed white circles). Solid lines show the location of multichannel seismic lines from the Australian Geological Survey Organization (thinner lines = Survey 75) and from the Leg 194 site survey (heavier lines = MAR data). Gray shaded areas show the estimated extent of the MP2 (early to middle Miocene) and MP3 (late Miocene to Pliocene) platforms. Dashed line shows the boundary of the Great Barrier Reef Marine Park.
