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 CO2 in the air and water. During the cruise the ship occupied 340 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'N 119°W and the other one at 6°02'N 118°58'W.
