Divers using SCUBA gear gathered and identified rockboring
pelecypods found in the subtidal outcrops of
Monterey silicious shale off Del Monte Beach, Monterey,
California. Underwater photographs were taken of all the
recognizable species present.
A species distribution and mapping survey was made.
along two transects, one of which would be subjected to
radical ecological change after isolation from the open
sea by a proposed breakwater project.
Most species found are common to both transects.
Their distribution is variable and depends to a great
extent on the character of the substrate, which varies
from soft, carbonate-rich mudstone to chert. However,
within this framework of distribution dependent on substrate,
there are inconsistencies which remain unresolved.
