A sea floor benchmark experiment was conducted in an area about 16 nmi west of Pt. Lobos, California (36°30' N x 122°17' W) during 18- 22 May 1985. Two baseline-crossing methods were used to determine the relative positions of acoustic bottom transponders. The method of least-squares adjustment was used to analyze the data. Relative position determination of the transponder array is discussed and recommendations are made for further improvement. The advantage of these methods is their simplicity. Their disadvantage is the relatively large amount of ship time they require to achieve acceptable accuracies. Transponder array such as the one deployed can be used for solving many types of problems in sea floor engineering, which will be of increasing importance in the future.
