2. General Summary
The loading of the ship for the mooring deployment was conducted on the
evening of 10 November after the K-O-K had returned from HOT-109. The
ship returned to port at 1715 and we began offloading immediately.
Once this was completed we began the loading of the gear for the
deployments of the HALE ALOHA mooring and the sediment traps. We
stopped at approximately 22:30 due to the long day the crew and
scientists had already worked. The loading was completed the following
morning and the back deck was subsequently secured.
A total of 11 scientists participated in the cruise aboard the R/V
Kaimikai-o-Kanaloa . The HALE ALOHA mooring and the moored sediment
traps were successfully deployed. Peter Williams, a visiting scientist
from the University of Wales, was able to collect water for a high
precision respiration incubation experiment which we may develop a long
term collaboration if results are promising. Dave Karl also did
experimental work as well.
3. Daily Activities
11 November, Thursday
We departed Snug Harbor at 0900 and arrived on station for the start of
the HALE ALOHA deployment at 1800 and the buoy was overboard at 1805.
Mooring deployment went well except for a set of missed cotter pins
which required some line to be recovered until the connection problem
was corrected. This amounted to a loss of approximately 30 minutes for
a total elapsed deployment time of 5:08.
12 November, Friday
A water collection CTD cast to 250m was performed followed by a cast to
500m. The sediment trap deployment was started at 1104 and the anchor
was dropped at 1258 for an elapsed time of 1:54 and at location 22
49.34 N and 157 52.54 W. A triangulation was performed to determine
the location of the sediment trap anchor which was calculated to be 22
49.226 N, 157 52.707 W. A calibration CTD was collected upon return
to HALE ALOHA. A three hour CTD yo-yo from 10db to 800bd was
started.
13 November, Saturday
Returned to Snug Harbor at 1215 and offloaded immediately.
