Central subtropical gyres of the North and South Pacific (P16S and P17S) part of the WOCE hydrographic program. Cruise included a section of full depth CTD and water sample profiles and Gerard barrel profiles along a line from 6°S to 33°S along ca. 13°W (WHP line P17) and from 37°30'S to 17° 30'S along 150° 30'W (WHP line P16). 97 CTD/rosette stations were occupied. Samples were analysed for oxygen, nutrient, salinity, CFC's, helium/tritium, CO2 and 14C. | ||||||||
