Pacific Ocean CTD and Nutrient Measurements from WEPOCS Cruises

Three years of Conductivity, Temperature, Depth (CTD) and nutrient data were collected during the Western Equatorial Pacific Ocean Circulation Study (WEPOCS I, II, III). The dataset covers the TOGA Area - Pacific from 30°N to 30°S, spanning from June 18, 1985 to July 28, 1988. Data was submitted by Dr. Roger Lukas of the University of Hawaii at Manoa and processed by NODC.

Use Cases

• Analyze nitrate concentration variations with depth (CTD profiles) to study nutrient distribution in the tropical Pacific.
• Model ocean heat content and salinity (from CTD conductivity) to understand water mass formation and circulation patterns.
• Correlate cloud amount/frequency observations with sea surface temperature data for air-sea interaction studies.
• Investigate temporal changes in ocean station data parameters across the three WEPOCS cruises from 1985 to 1988.

Strengths

• Data collected over a three-year period from 1985 to 1988, providing a multi-cruise time series.
• Geographic coverage spans a large latitudinal band in the Pacific Ocean from 30°N to 30°S.

Limitations

• Specific row count, column details, and sample size are unknown.
• Data is temporally stale, with the last update recorded in July 1988.
