APPENDIX B. 
Data Collecting Activities 
Weather - Recorded by bridge every three hours. Picture of the 
sky taken every two minutes during the day. Continuous recording 
of sea temperature, solar radiation and wet bulb, dry bulb 
difference. 
Plankton Tows - Average of eight per day or 2 per station - one 
surface and one oblique. 
Micronekton Tows - Twice a day. Once at night and during the 
night. 
Temperature and Salinity with Depth - Taken on the average of 
every twenty miles. Some stations only had temperature and depth 
recorded. 
Chemical Nutrients in the Water - Average of four times a day. 
Recorded at various depths. 
Surface Chlorophyll - Continuous recording in addition to detailed 
analysis twice a day. 
Carbon Dioxide - Continuous recording of C0 P in the air and water. 
During the cruise the ship occupied 3^0 stations which varied 
from simple recording of temperature with depth to long stations 
with shallow and deep hydro casts, plankton tows, micronekton tows 
and temperature and salinity with depth. Twenty miles was the 
average spacing of the station, but near the equator the distance 
was shortened. Two buoys were anchored at sea to continuously 
record environmental data when ships were not in the area. One 
was placed at 9°37 T N 119°W and the other one at 6°02 T N ll8°58 r W.
