Glass Sponge Reef Symposium was held at the Institute of Ocean
Sciences in Sidney, B.C. on October 28-29, 2008. Many of the
researchers and conservationists working on glass sponges associated
with reefs were present. At the end of the symposium a workshop was
held to look at priority areas for research and conservation. This
is being compiled but in the meantime a few points are listed below
for Cloud Sponges.
Direct experimental evidence that
high silica required for growth
> Determination of maximum age of
> Length of time dead main frame
> Length of time the attachment of
dead main frame to rock substrate remains solid
> Occurrence of glass sponge reefs in
the Bering Sea: “The Sea of Glass”.
> Use of skeletons of known age as
indicators to date past depths of anoxia in
periodically anoxic fjords.
> Potential association of cloud
sponges with methane seeps
Compare and contrast biology/ecology of cloud sponges with other two
species of sponge reef builders
> Full, long term protection
of sponge reefs from commercial trawling.

permanent transect set up by divers at Senanus Reef. Our
plan is to resurvey the transect over future years. A brief
sequence along the transect is shown here.
