A.2.b	Stations occupied

Observations of PR2 were carried out as part of the R/V
Ryofu Maru cruise RY9101 Leg 1.

Number of Stations
          A total of 33 CTD/rosette stations for PR2 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.

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 at every 5 degrees
in latitude. On other stations, water samples were taken at
shallower depths than 1250m. Surface water samples were
collected by a bucket at every station.
 
A.2.c	Floats and drifters deployed

A.2.d	Moorings deployed or recovered
