Abstract
The profilometer developed for attachment to sediment corers to obtain an in situ sound speed profile during coring operations, which was described at Ocean 72, has been refined and used to collect additional data. The refinements, including an automatic gain control, are discussed. Sound speed data and core analyses demonstrating the measurement capabilities and usefulness of the profilometer are presented.
