DIVER PERFORMANCE MEASUREMENT: UNDERWATER NAVIGATION DEPTH MAINTENANCE WEIGHT CARRYING CAPABILITIES.
Abstract
Underwater measurement techniques were developed and applied to test the capabilities and limitations of free-swimming scuba divers in transporting objects with varying degrees of negative buoyancy, and to determine the effects of weight location on performance. The conditions of negative buoyancy consisted of 3-pound, 6-pound, and 9-pound weights, either attached to the diver's body or handheld by the diver. Quantitative data was obtained using a diver communication/telemetry system. The measures of diver performance recorded included: diver depth, air consumption rate, swimming speed, and navigational accuracy. The tests were performed in water 32 feet deep over a 780-foot underwater test range. The causes for resulting performance decrements are discussed in terms of weight and weight location effects. Practical implications of the study results are reviewed. (Author)
