The accomplishments of Leg 171A depended on a flexible ODP science structure that allowed the minileg and provided the extra resources necessary for the LWD program. Success of the operations at sea depended on the reliable, high-quality instruments provided by Anadrill-Schlumberger and its dedicated engineers. Additionally, the ship's crew, the drilling crew, and the ODP technical support staff provided unfailing assistance.
