[Coral-List] Allen Coral Atlas - Monitoring User Survey

This reminds me that I forgot to comment when the Atlas was released.  I
took a look at the atlas maps for Tutuila, American Samoa, where I have
lived for 16 years.  I found some rather large areas which are highly
likely to be incorrectly scored.  One is a shallow, very murky bay, with a
mud bottom, which is between the airport and the main part of the island.
Not sure how deep the mud is on top of the underlying rock, but it was all
scored as rock.  Another is that the harbor, which is about 200 feet deep,
has a large light blue patch in it, which as best I can tell from the
legend, is supposed to be coral (there are some shades that are pretty hard
to tell apart, I would suggest using colors that are more distinct..  Most
of the time the harbor is pea soup green with about a 10 foot visibility or
less.  Even if it was clear, I can't imagine a satellite photo could see
200 feet deep with any accuracy.  And as far as I know, the bottom of the
harbor is mud that is so soft that multibeam sonar used by NOAA for
surveying could not detect the surface of the bottom, not hard enough to
reflect sound waves.  I was told that by a leader of the NOAA team over 15
yrs ago.  I was told by a technical diver that there is a deep sponge
community somewhere in the harbor, but I don't know where that is.  Also,
an area of mangroves along the shore of that muddy bay (Pala Lagoon) did
not show up in the atlas.
Cheers,  Doug
