Summary of Activity and Data Gathered:
Staff: VeeAnn Atnipp Cross, Kenneth E. Parolski
Notes: A second component of the field work will include coring that will be completed during the week of July 11-18. This part of the work will require a P-code navigation system with a navigation laptop with MapInfo on it. The rest of the coring gear will come from elsewhere. Original Center People field contained: Ken Parolski - sidescan/seismic tech., VeeAnn Cross - data processor.
