A.4	Scientific Programme and Methods

This cruise started from the Keelung Port at Northern Taiwan as cruise 
number 334 of R/V Ocean Researcher 1.  The first part is hydrographic 
survey (October 29-30) over PCM 1 line that is east of northern 
Taiwan, before switching to PR20 line (October 31 - November 7) that 
is east of southern Taiwan.

Unfortunately, the severe swell under the notheast monsoon (which was 
mostly above 30 knots) has kept the ship sailing at zigzag path 
between stations.  Even the ship-board ADCP showed signs of 
sea-sickness, i.e. there were large random errors in both ADCP and GPS 
data, and the profiler can hardly reach 200m depth.

When reaching Pr20 on October 31, the hydraulic pipe for the A-frame 
had a rupture on the first station.  It was fixed and we decided to 
head towards Taiwan from station 19.  There was more furniture damaged 
while carrying out CTD surveys towards station 1, and deploying ARGOS 
drifters near station 4 on November 3.
