Project 2.5a work will be presented in their final reports. However, the preliminary data from the work of these two agoncios indicates that a conbins- tion of the two approaches to the problem will materially benefit previous incomplete documentation of PPG fall-out patterns and shows a great decal cf promise for future operations. In fact, it appears that the problem of de- lineating the fall-out pattern for very high yield shots in the Pacific can be solved on future cperaticns it‘aajor support is given to a project built around the findings of the two water survey nsthods outlined above, (e) The HSL plan of operation previded for one man to be stationed at the task force command post as supervisor of the activities ind one man (later two) to perform the necessary maintenance and setting up of instruments at the many ground staticns. «as the operation progrossed it becans apparent that tho workload wes somewhat mre than could be aecomlished by the team, especially in the matter of traveling arsund to the varivus sites to make repairs and adjustments to the instruments and in the matter of clerical assistance at the command post. The net result of the former was the necessity for setting up dome special flights on an enerzency basis, or the loss to the HASL project of data froma station if a visit proved impossible. The result'of the latter was a constant drain on the clerical facilities of the task force. It appears that for the future, it would be less expensive ani less disruptive of task force operations if more personnel were assigned to the project, 5.
