Figure 3. Ewing 9009 MCS profile 1002; Leg 174A shelf Sites MAT-8B and MAT-9B are located approximately along this line, as shown, as is secondary upper slope Site MAT-13A (see also Fig. 1). Note the pronounced progradation of late Paleogene-Neogene clinoforms. These clinoforms, and the sea-level signal they hold are the scientific focus of MAT drilling on the shelf. Selected sequence boundaries are labeled, for comparison with interpreted site-specific Oceanus 270 profiles. Upper slope drilling, if it takes place, will augment the results from Leg 150 by adding to existing chronostratigraphic control.
