A.2.b	Stations occupied

Observations of PR3 were carried out as part of the R/V
Ryofu Maru cruise RY9210 Leg 2.

Number of Stations
          A total of 15 CTD/rosette stations was occupied using a
General Oceanics 12 bottle rosette equipped with 12 1.7-liter
Niskin water sample bottles, and an NBIS MK III B CTD. No
additional sensors were used with the CTD system. We used two
CTD under-water-unit. Because of the trouble of FSK signal, we
had to change the under-water-unit while the cruise.

Sampling
          The following water sample measurements were made:
salinity, oxygen, nitrate, nitrite and phosphate on all
stations. The depths sampled were: 10, 25, 50, 75, 100, 125,
150, 175, 200, 250, 300, 400, 500, 600, 700, 800, 900, 1000,
1250, 1500, 2000, 2500, 3000, 4000 in meters. Surface water
samples were collected by a bucket at every station.
