CMRC3 CREWS Field Log

CREWS STATION CLEANING CHECKLIST
Station ID: CMRC3 (i.e. CMRC3, SRVI1)
DATE: 12/09/05 Start time: 08:45am End time: 09:15am

Type of cleaning: x BASIC
COMPLETE
CTD Validation
BASIC Cleaning:
x Surface inspection
x Underwater inspection – station support lines, chains, mounting pins
x Optical sensor cleaning
x CTD screen cleaning
Optional sensor cleaning
o PAM fluorometer monitoring heads
o SAMI pCO2 cage or inlet
o Other, please specify_________________________________

Comments: Diving is still not possible and so cleaning was conducted by snorkeling. PAM heads could not be cleaned entirely, but the acrylic lenses were wiped clean in-situ. pCO2 cage has not been replaced yet.


COMPLETE Cleaning:
(Finish basic cleaning plus these additional steps )
Perform CTD validation
Clean all growth from spectra lines and chains
Inspect shackles
Base plate and grounding plate inspection
Clean spectra lines at base plate
Clean body of CTD(s) and light sensor(s)
Clean all optional sensors
o PAM fluorometer distributor box, mounting stands, and cables
o SAMI pCO2 stainless mounting hardware and body
o Other, please specify_________________________________

Comments: As diving is not possible at the moment, cleaning was conducted on snorkel. Because of this we were unable to clean the PAM fluorometer monitoring heads in the usual manner. Instead the acrylic lenses were wiped clean in-situ, rather than removing the entire casing. The SAMI pCO2 is yet to be replaced after removal.

CMRC2/3 CREWS Field Log

DATE: 10/11/05
TIME: 1700
STAFF: K. Buch, W. Goossens
BOAT: Lucaya (1/2 day use; 0.5 engine hrs)
NOTES: removal of SAMI pCO2 instrument. PAM-monitored Agaricia colony 90% bleached; difficult to tell amount of live tissue (will closely inspect on 10/14/05). PAM-monitored Siderastrea head showing paling over most of colony. Also noticed that PAM heads are showing some fouling-will revisit on 10/14/05 for cleaning/inspection.

SAMI pCO2 system removed for service

The SAMI pCO2 instrument, deployed on May 21, 2005, was removed for scheduled maintenance and calibration on Oct. 11, 2200 GMT. It is anticipated that servicing and replacing the instrument at the site will take no more than 6 weeks.

Thanks to Kevin Buch and the crew at LSI for taking care of the instrument and CMRC3 throughout this deployment.

DATE: 9/14/05
TIME: 0920
STAFF: Buch, Coutts (intern)
BOAT: Lusca (1/2 day use; 0.5 engine hrs)
NOTES: thorough cleaning, including re-positioning of PAM heads and cleaning inside of SAMI “cage”. Widespread local bleaching occurring, including Stick site and N. Norman’s Pond patch reef. PAM Agaricia head is approximately 40% bleached. PAM Siderastrea head showing mild paling at base.

Summary of Coral Species Being Monitored

This is a short summary of the species being monitored by the pulse amplitude modulating (PAM) fluorometer at this CREWS station. The instrument itself has 4 individual heads on about 10 - 15' cables connected to a central distributing unit (AKA distributor box). The signal from these 4 heads is delivered through the distributor box to the station as a single RS232 formatted signal. The four heads are mounted into two mounts with enough freedom in motion to be oriented appropriately, including angle and distance to coral surface, to allow monitoring of up to 4 different species. We have typically aimed to monitor only 2 species each in duplicate. The PAM heads are numbered 1 through 4. A list of the species monitored and the dates they are monitored follows.

5/21/05 1800 PAM1 Agaricia sp.
PAM2 Siderastrea siderea - side of colony
PAM3 S. siderea - small secondary colony near agaricia colony
PAM3 S. siderea - top or same colony monitored with PAM2

5/23/05 0500 All heads failed - pressure case corrosion issues

6/30/05 2000 PAM Redeployed with aluminum distributor box and stainless steel monitoring heads
PAM1&2 Agaricia sp.
PAM3&4 S. Siderea

7/11/05 1400 All heads failed - continued corrosion issues
7/13/05 0000 PAM3 still off, PAM1,2&4 begin reporting again
PAM1&2 Agaricia sp.
PAM4 S. siderea

7/23/05 1600 Second PAM unit deployed - corrosion issues resolved
PAM1&2 S. siderea
PAM3&4 Agaricia sp.

Currently, all heads are reporting. Based on reduction in PAM yields, the S. siderea species is showing signs of stress.
