First Paragraph
Since the inception of the Deep Sea Drilling Project (DSDP) and during the Ocean Drilling Program (ODP), scien-tific ocean drilling has been almost wholly confined to outer-shelf water depths or greater, and there was no capability to drill in ice-covered waters. Consequently, a wide range of targets and environments were inaccessible to scientists. As a clear scientific demand developed to obtain cores from more difficult environments, coring platforms other than those traditionally used by DSDP and ODP were required to achieve scientific goals.
