D/V Chikyu: Riser Operations and the Future of Scientific Ocean Drilling

Daniel CurewitzAsahiko Taira
First Paragraph

Earth science disciplines focused on investigation of climatic, ecological, or tectonic change as recorded in geological deposits (e.g., paleoceanography, marine micropaleontology, paleoclimatology, paleomagnetism) require high-resolution, continuous, well-preserved records for accurate analysis. Recovery of long, uninterrupted, relatively undisturbed sections has long been a primary technical challenge for any drilling operation. Recovered cores and geophysical measurements form the backbone for any further data collection and data analysis. Limitations on core recovery, core condition, and sample preservation have long been recognized as serious challenges for any reconstructions or interpretations of the geological record.
