Australian Western Equatorial Joint Global Ocean Flux Study (JGOFS) Data

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.澳大利亚赤道全球海洋通量联合研究（Joint Global Ocean Flux Study，JGOFS，简称OzGOFS）考察于1990、1992、1993年的三次航次中开展，航次断面覆盖沿147°E的6°N至2°S海域，以及沿155°E的约12°S至10°N海域。其中FR 08/90航次于1990年10月2日至17日开展；FR 05/92航次于1992年6月15日至7月13日进行；FR 08/93航次于1993年11月5日至12月1日实施。FR 05/92的两个航段数据已合并为磁盘上的单个“航次”。 1990年航次（FR 08/90）实施于1988/89年拉尼娜（La Niña）事件之后、1991/92年厄尔尼诺（El Niño）事件之前。1992年（FR 05/92）与1993年（FR 08/93）航次则开展于持续厄尔尼诺事件的中期与末期。 本次航次的考察目标如下： 1) 测量西赤道太平洋海域pH、二氧化碳及荧光的垂直与水平剖面； 2) 研究该海域的初级与次级生产力； 3) 探究调控碳在海气界面及水柱内垂直通量的物理、化学与生物过程； 4) 研究太平洋西边界赤道区域生物量升高的化学、物理及生物过程； 5) 借助脂质、色素分析等化学方法，表征不同水团内的浮游植物群落结构。 本数据集涵盖声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，ADCP）数据、叶绿素a与浮游植物色素、温盐深仪（Conductivity-Temperature-Depth，CTD）数据、蓝细菌与细菌、天然放射性核素、营养盐、初级生产力、沉积物捕获器数据、表层fCO₂、痕量金属以及浮游动物数据。
