Corals from the Seychelles Islands, IndianOcean, occur mainly as small coralline algae-vermetid remnants found in cavities adhering to the rock surface. This paper presents results of new TIMS 238U-234U-230Th measurements on coral samples from
the islands La Digue and Curieuse and discusses their ages in relation to elevation and the last-interglacial sea level.

This study examines the hydrodynamic processes and sediment transport in 11 hoa (shallow cross-reef channels) in the Cocos (Keeling) Islands, IndianOcean. Emphasis is on the characteristics of tide and wave-induced current processes and sediment

This paper illustrates how studies of the geomorphology of oceanicislands can contribute to the understanding of nearby plate boundaries. For this purpose, an oceanicisland is defined as one within an ocean basin. Case studies are given of three
Vertical movement of isolated oceanicislands at plate margins : evidence from emergent reefs in Tonga (Pacific Ocean), Cayman Islands (Caribbean Sea) and Christmas Island (IndianOcean) in The geomorphology of plate boundaries and active
This paper examines the evidence for vertical movement of oceanicislands at three plate margin locations. Each is located adjacent to a deep ocean trench, but represents a different plate margin setting from a different ocean. For each of the areas
elevation of Tertiary reefal limestone indicates past uplift and/or differential movement of islands within the group. Evidence for continuity of vertical movements is examined, particularly elevation of emergent reefs of Last Interglacial age.
New sea-level and δ 18O curves for the past 34,000 yr, based on uranium-thorium chronology, are proposed for the southwestern part of the IndianOcean. The archives include cores drilled from onshore coral reefs and submersed samples from foreslope
corals of Mayotte in the Comoro Islands. The deglacial sea-level rise is clearly recorded. The deglaciation phase is characterized by a strong 18O depletion marked by 2 pulses related to meltwater discharges into the North Atlantic Ocean but also
characterized by responses specific to the tropical IndianOcean.

Fifteen hundred sooty albatrosses were ringed since 1966 at the Ile de la Possession, Crozet Archipelago, Southern IndianOcean, and a detailed ecological and behavioural study of this population has been carried out from 1978 to 1982. The breeding
