Equipment Used

|
|
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.
