WOCE & JGOFS Sampling

All primary sampling work was completed at both Kahe Point and Station
ALOHA on this cruise.


CTD and XBT Operations

There were some problems with the flash fluorometer on this cruise, due
to a corroded connector. Otherwise, CTD operations were completed
successfully. No XBTs were deployed on this cruise.


Primary Production and Sediment Trap Measurements

Primary production was measured in situ for 12 hours and on-deck for 24
hours; sediment trap collections were successful.


Optical Measurements

Samples for dissolved gases were collected for Charles Keeling of
Scripps and for Steve Emerson and Paul Quay of the University of
Washington.
