Equipment Used
scuba
Purpose
Map the underwater reefs and topography, sea level changes, underwater
oil deposits, sedimentation dynamics of the ocean floor, growth rate of algae,
migration patterns and growth rates of plankton, reef habitat, movements and
behaviors.
Information to be Derived
Map of underwater reefs, bathymetry, sea-level change data, biohabitat
Summary
Worked for 58 days at 50 ft depth. Compilation of a detailed map that
delineated bottom-sediment types over the area within swimming range (about 1000
ft) of the habitat. Studied rates of reworking on organisms on sand flats
adjacent to coral reefs in the vicinity of the habitat and found that the upper
layer of sediment is completely reworked in only a few days. Artificially
constructed ridges comparable to sand ripples were obliterated by organisms
within a week. Studies also showed that empty pelecypod valves in the low-energy
reef environment generally lie concave side upward, a distinctly different
orientation than that formed by wave and current activity along a high-energy
coast; such differences may be useful for identifying ancient depositional
environments.
