Scientific objectives

Based on IODP Proposal 681-Full2, this expedition will investigate the constructive and destructive processes of volcanic arcs by drilling sites along the Lesser Antilles Arc. The primary objectives are (1) to characterize the processes and timing of eruptive activity along the arc, (2) to reconstruct volcanism during the early marine and subaerial stages of volcano construction, (3) to identify the mechanisms controlling triggering, transport, and deposition of submarine debris avalanches from collapsing island volcanoes, and (4) to assess the role of erosion, fragmentation and incorporation of sediments and water in debris avalanche mobility with implications for risk assessments.
