A.2.a	Geographic boundaries

A.2.b	Stations occupied

Observations of PR2 were carried out as part of the R/V Ryofu
Maru cruise RY9011 Leg 1 and Leg 2, and those of PR3 were Leg 3.

Number of Stations
          A total of 28 CTD/rosette stations for PR2 and 5 stations
for PR3 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. In addition, a total of 17 CTD stations for PR3 was
occupied. No additional sensors were used with the CTD system.

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 on every station of PR2. On PR3, water
sampling was carried out at only stations every 5 degrees in
latitude. Surface water samples were collected by a bucket.
