The Tahiti Sea Level Expedition Proceedings Volume 310 is now available on-line.

The Scientific objectives of this Expedition are;

  1. Establish the course of postglacial sea level rise at Tahiti (i.e., define the exact shape of the deglaciation curve for the period 20,000-10,000 cal. y BP).
  2. Define SST variations for the region over the period 20,000-10,000 cal. y BP.
  3. Analyze the impact of sea level changes on reef growth and geometry.

To meet these objectives, the last deglacial reef sequence, which consists of successive reef terraces seaward of the living barrier reef, was cored from a dynamically positioned vessel during October and November 2005. Cores were recovered from 37 holes across 22 sites at depths water depths ranging from 41.6 to 117.5 m, with a conventionally calculated recovery of 57.47% (total length of hole drilled = 1,100 m; total length of core recovered = 632 m). Borehole logging operations in ten boreholes at seven sites provided continuous geophysical information about the drilled strata. Cores were described during the Onshore Science Party at the IODP Bremen Core Repository during February and March 2006, where minimum and some standard measurements were made. The proceedings include scientic results of the offshore and onshore parties of this expedition. Further postcruise research on samples taken during the Onshore Science Party is ongoing to fulfill the objectives of the expedition.
