Here is a call-for-information from anyone with knowledge of "drowned"
or "submerged" reefs in any ocean.
Bill Precht and I (J Kleypas) are compiling a database of known and
suspected drowned and submerged reefs of either Holocene or Pleistocene
age.
I have managed to glean a bit of information from the literature,
most of which addresses the Caribbean area (see Table 1 below).
IF ANYONE KNOWS OF ANY DROWNED OR SUBMERGED REEFS (or features
suspected of being reefs) NOT LISTED IN THE TABLE BELOW, COULD
YOU PLEASE SEND ME AN E-MAIL WITH THE FOLLOWING INFORMATION?
******************************************************************
please send any responses directly to: kleypas at ncar.ucar.edu

We are looking for both published and non-published information,
and will certainly acknowledge any information you might have in
providing any of the following:
LOCATION:
LAT & LON:
DEPTH (m):
SUSPECTED AGE (if known):
MEASURED AGE (if measured):
REFERENCE (if published):
HOW FEATURE WAS DETECTED (e.g. SCUBA, submersible, ROV):
ADDITIONAL INFORMATION (e.g. size or length of feature, any
currently coral growth on the feature, any samples collected)
TABLE 1. Reported ages and Depths of drowned or submerged reefs.
