| The Rapanui Expedition consisted of three legs. The first leg (named Manrap) was a transit between Manzanillo, Mexico and Easter Island, Chile, the second leg (Rapanui 1) consisted of work on the Rapanui (Easter) microplate and was the primary workload of the expedition, and the third leg (Rapanui 2) was a transit from Easter Island, Chile to Tahiti, French Polynesia, and realized additional work on the Rapanui Microplate, and a fuel stop at Hao, French Polynesia. Instrumentation on all legs consisted of standard geophysical tools used on the N/O Jean Charcot . |

| The Carlsberg Ridge (CAR) is the present plate boundary between Somalia and India. It extends north of the Equator from 57 degrees E at Owen FZ to 66 degrees E where it joins the Central Indian Ridge (CIR), the NW-SE main ridge trend changing to N-S. In the 1960s, CAR was one of the first mid-oceanic ridges to be surveyed, and in the McKenzie and Sclater (1971) Indian ocean synthesis its evolution appears as one of the soundest results of that work: fast spreading from A28 (anomaly 28 epoch) to A23, slow spreading from A5 to the present. After the identification of the A20-A24 series in the Arabian basin by Whitmarsh (1974), no new specific study was devoted to this ridge, although the extensive survey of the surrounding areas showed its probable complex... |

| High-resolution records of the geomagnetic field intensity over the last 3.5 Myr provided by paleomagnetic analyses of marine sediments and volcanics have shown the occurrence of short-lived low field intensity features associated with excursions or short polarity intervals. In order to evaluate the ability of marine magnetic anomalies to record the same geomagnetic events, we have collected six deep-tow (similar to500 m above the seafloor) and several sea surface magnetic anomaly profiles from the Central Indian Ridge across the Brunhes, Matuyama, and Gauss chrons (i.e., from the ridge axis to anomaly 2A). After removal of topography, latitude, and azimuth effects, we converted distances into time sequences using well-dated polarity reversal anomalies as... |
