Figure 3. Site summary profiles showing sedimentary units, coral assemblages, ages, and paleowater depths (in red) for Maraa, Tiarei, and Papeete.

Excluding Papeete, and Maraa site 17A, each hole has a thin basal fringing-reef unit overlain by framework units in which the paleowater depths increase up-core. The basal fringing-reef unit overlaps in elevation between sites 16 and 12A, and between sites 7 and 5, showing that it forms two layers (highlighted in orange). The break between layers at sites 12A and 5 coincides with Meltwater Pulse 1a.
