particularly village {stands would be surveyed, and additionally several smaller islands such that eacn quadrant of the atoll would be measured if there were islands in ail quadrants. Because of the distances between atolls and the Targe number of islands to be surveyed, the survey was divided into three separate trips with refueling, resupply, and Totatiomf survey personnel between the trips.
