ship will therefore be available in the Eniwetok area no earlier than 18 November. Aithough it will be very useful to utilize the Palumbo in the Eniwetok lagoon survey we are unable to plan on its availability. In order to conduct a meaningful program early in the survey, additional vessels are being readied for the lagoon work. 1) LLL Boston Whaler - 17' length They include: Equipped with bottom depth indicator; 65 HP Mercury outboard and 7.5 HP auxillary motor; davit for over the side work with approximately 500 feet of 3/32" steel cable on a hand-operated winch. The vessel will be available for coring, water sampling, dredging, plankton tows and in-~ situ detection measurements. xan ban seitbintachinsintsties2 <* Ste near-shore and reef work. 2) The ship will be used principally to support | An "A" frame is presently under construction to mount on the LCU now enroute to Eniwetok. A portable gasoline engine-powered winch con- taining 1000 feet of 3/32" stainless steel hydrographic cable will also be mounted on the vessel. The LCU will have the capability to conduct all phases of marine sampling and would be used principally to sample the off-shore regionof the lagoon, 3) Other ships of opportunity would be used to ferry personnel and gear to reef areas and, when practical, to assist in plankton tows. If and when the Palumbo arrives in Eniwetok, its facilities will be employed to supplement the on-going program. If, however, the two 1m ee facilities (Boston Whaler and the LCU) are the only ships available, a complete program addressing all the survey goals could be conducted in 10~12 weeks without the Palumbo. This estimate is based on having perfect weather the entire period for 8-10 hours per day, 6-7 days per week. A network of buoys will be placed in the lagoon as fixed reference points during the survey. All personnel operating the whaler and sampling from the LCU will be trained and knowledgeable in all sampling techniques. RRA A Le OIRO aie Aen All samples gathered will be properly coded and sample locations plotted on charts. Locations will be determined by-using sighting compasses and estimates based on running time and speed from fixed reference points. The Whaler will contain all necessary safety equipment and tow a spare 6 man raft. a The raft will be a means of transport to shallow reef areas. The aquatic program, independent of the Palumbo, will require five
