Search in the Dark

With such limited vision it is difficult to be sure that the area has been searched thoroughly. For this purpose a grid is devised and the Hercules follows this pattern to search the sea floor for the missing bottle. Various shapes and methods are used for this kind of search. In such darkness, 90 degree turns at set intervals is an approach that seems viable. Image courtesy of Dr. Peter Girguis, Lost City science party.
