Three cruises (POP 1, SEAPSO 3 and SEAPSO 4) carried out during the "Tour du Monde" of the R.V. Jean Charcot allow us to obtain new structural and geochemical data for the Okinawa, North Fiji and Lau basins. Taken together, the structural and geochemical data illustrate a difference in evolution stages of these sites. The less evolved stage is represented by the Okinawa basin, where accretion is evidenced only by volcanic intrusion into a thinned continental crust. The most evolved stage is illustrated in the North Fiji basin, where the present-day accretion can be directly compm·ed to the East Pacific Ridge. The Lau basin displays an intem1ediate stage with a complex system of accretionary ridges. This difference in the evolution stage is translated in... |

Understanding the Earth´s present day climate and predicting its future evolution require investigation of high resolution sedimentary archives providing critical information of past oceanic and atmospheric variability. This study is based on two continuous marine sedimentary successions (Cores MD06-3067 and MD06-3075), recovered close to Mindanao Island (Philippines). The Indo-Pacific region represents a major source of heat and moisture, which are redistributed to the high latitudes by atmospheric and oceanic circulations; thus this region is a major actor in regulating global climate. The two cores investigated in this work are located within the inflow path of the Indonesian Throughflow. This ocean current provides a critical link within the... |
