2.	GENERAL SUMMARY

All objectives of the JGOFS and WOCE programs were accomplished.  All
planned stations were occupied. All core samples were taken and the 36
hour CTD burst sampling period was not interrupted. All samples for
ancillary projects were taken. Floating sediment trap array and primary
production array deployed and recovered succrsfully. No samples were
lost during the in-situ incubation. There were no major equipment
failures.  The optical plankton counter was towed from Station ALOHA to
Honolulu without any problem.


3.	R/V MOANA WAVE, OFFICERS AND CREW, TECHNICAL SUPPORT

The R/V Moana Wave continues to maintain the excellent ship support for
our work. The officers and crew were most helpful and accommodating.
They showed enthusiasm and concern for our work and were very flexible
in receiving changes in our operational schedule. Technical support
during this cruise was excellent. STAG personnel were abvailable at any
time to assist in our work and made things much easier for us.


4. 	DAILY REPORT OF ACTIVITIES

January 12, 1996; Loading Day

All equipment were moved into the ship from either SNUG Harbor labs or
UH on this day. All electrical and electronic connections were made for
the CTD and the OPC/v-fin. All lab equipment were stowed away and
secured. All instruments were tested and appeared functioning. No
problems were encountered.

January 15, 1996

All hands arrived on ship at 0830 and we departed at 0900. Fire and
emergency drills were conducted at 1000 followed by a safety briefing
by the first mate and a short science meeting. Arrived at Station Kahe
at 1130. Conducted weight cast and 1000 m CTD cast. All operations and
sampling accomplished by 1400. Started transit to Station ALOHA.
Arrived at Station ALOHA at 2200. Sediment trap array deployment
procedures began at 2300, accomplished at 2400 (0000).

January 16, 1996

WOCE deep cast at 0030, completed at 0800. CTD burst sampling commenced
at 0900. CTD casts maintained at 3 hour intervals. Noon and midnight
zooplankton tows accomplished.

January 17, 1996

CTD casts continued at 3 hour intervals. Go-Flo cast conducted at 0230,
finished at 0330. Primary production array deployment commenced at
0600. CTD casts continued at 3 hour intervals. Zooplankton tows
conducted at noon. Retrieval of primary production array commenced at
1800. No samples were lost. CTD casts continued at 3 hour intervals.
One night tow was accomplished. Last 1000 meter cast conducted at 2100.
Transit to pump tanks at 2300.

January 18, 1995

Returned to the center at 0100. Deep cast conducted at 0130, completed
at 0500.  Proceeded to location of sediment trap array. Arrived at site
and commenced recovery at 0800, accomplished at 1000. OPC deployed to
conduct transects through Station ALOHA. Break-off from transect at
2100 and proceeded to Honolulu with OPC in tow.

January 19, 1996
