The Australian Equatorial JGOFS (OzGOFS) investigations were conducted on three cruises in 1990, 1992 and 1993 on transects along between 6oN and 2oS along 147oE and between about 12oS to 10oN along 155oE.

FR 08/90 was made between 2-17 October 1990; FR 05/92 between 15 June and 13 July 1992, and FR 08/93 between 5 November and 1 December 1993. Data from the two legs of FR 05/92 have been combined into a single “cruise” on the disk.

The cruise in 1990 (FR 08/90) was carried out after the 1988/89 La Nina but before the 1991/92 El Nino event. The cruises in 1992 (FR 05/92) and 1993 (FR 08/93) were done during the middle and end of a prolonged El Nino event.

The objectives of the cruises were:

1) To measure vertical and horizontal profiles of pH, carbon dioxide and fluorescence in waters of the western equatorial Pacific Ocean.

2) To study the primary and secondary productivity of these waters.

3) To study the physical, chemical and biological processes that determines the vertical fluxes of carbon across the air-sea interface and within the water column.

4) To study the chemical, physical and biological processes leading to increased biomass along the equator at the western boundary of the Pacific Ocean.

5) To use chemical methods, such as lipid and pigment analyses, to characterize the phytoplankton community structure within different water masses.

Data includes Acoustic Doppler Current Profiler (ADCP) data, chlorophyll-a and phytoplankton pigments, CTD, cyanobacteria and bacteria, natural radionuclides, nutrients, primary production, sediment trap data, surface fCO2, trace metals and zooplankton data.
