Improving Absolute Distance Estimation in Clear and in Turbid Water

Abstract

Since the errors made in estimating distance under water are dependent on the degree of water turbidity, improvement through training in one body of water will not transfer to another body of water if there is a large difference in turbidity. This experiment demonstrated that the transfer problem can be overcome by training divers under different turbidity conditions so that they learn to tailor their corrections to the prevailing conditions. This training procedure would be useful for all diving tasks in which the estimation of object distances is important.
