CALCIFICATION ACCRETION UNIT (CAU) ASSEMBLY, DEPLOYMENT and RECOVERY
CAUs are composed of two 10 x 10 centimeter (cm) flat, square, gray PVC plates, stacked
1 cm apart.
Five CAU units are deployed per site on individual stainless steel stakes driven into
the substrate. The units are deployed in a clustered group with the spacing between
each unit being 0.5 to 5 meters. CAU sites are situated at an average depth of 15
meters. Units are placed so the CAU plates are ~10 cm above the surface substrate
and the top of the CAU plate is parallel to the surface of the water.
CAU units are recovered from the seafloor 3 years after deployment (in some cases
longer). Refer to the data files for the individual CAU site to determine the exact
deployment time of a specific unit.
Refer to the Calcification Accretion Unit (CAU) Assembly, Deployment, and Recovery
Standard Operating Procedure (2015) for a detailed description of the protocols.

CALCIFICATION ACCRETION UNIT (CAU) LABORATORY ANALYSIS
Once CAU units are recovered they are disassembled and each plate is rinsed with freshwater
to remove loose sediment, sand and mobile fauna. The plates are photographed and individual
images are captured of the Upper Plate, Top Side; Upper Plate, Bottom Side; Lower
Plate, Top Side; Lower Plate, Bottom Side. These images can be analyzed to determine
benthic composition on each plate surface. If pieces of calcified material fall off
during the photographing process, the pieces are retained with the plate for the dissolution
process.
After the plates have been photographed they are rinsed with fresh water and placed
on a pre-weighed drying plate along with any dislodged pieces, and left to begin drying
at room temperature for 24 hours and TO allow excess water to be removed. The drying
plate assembly is then placed in the oven to dry at 60 degrees Celsius. If the difference
in weights is less than 0.2 grams, the plates are considered dry and no further drying/weighing
is required. If the difference in weights is greater than 0.2 grams the drying/reweighing
process is repeated for as many 24-hour cycles as needed to obtain a difference of
less than 0.2 grams. It should be noted that since the initial sample processing in
2012, the standard weighing protocol has since been improved such that the acceptable
weight difference is 0.1 grams.
Once the plates are dry, each plate is placed in 5-10% Hydrochloric Acid (HCl) solution
to dissolve the calcium carbonate materials. The plate is scraped to remove all materials
and rinsed with the dilute HCl solution. The plate is then placed in the oven at 60
degrees Celsius to dry for 24 hours before the dry plate is obtained. Through the
entire dissolution process all dilute HCl rinse solution is preserved for later filtering.
The dilute HCl rinse process is repeated on all materials removed from the plate until
the dissolution process has stopped and all calcium carbonate material has been removed.
The fleshy material and used dilute HCl rinse materials are then separated using a
vacuum filtration pump by pouring the solution into a Buchner funnel, mesh layer and
pre-weighed filter paper. The filter paper and fleshy material are then dried and
weighed to determine the weight of fleshy algae present on each plate. The weight
of calcified materials on each plate is determined by difference, where the initial
weight of the dried plate (prior to the dissolution process) minus the fleshy material
weight equals the weight of carbonate material dissolved. The resulting calcification
rates are reported in units of grams/area/time.
Refer to the Calcification Accretion Unit (CAU) Laboratory Analysis Standard Operating
Procedure (2015) for a detailed description of the protocols.
