[ Derived from parent entry - See data hierarchy tab ] The central part of the WOCE Hydrographic Programme was the one-time survey of the World Ocean. This survey was conducted along a number transoceanic sections. At each hydrographic station full-depth profiles of temperature,salinity,and other parameters were obtained.Large and small volume bottle samples enabled a variety of chemical properties to be analysed, including nutrients, COD, CFCs, tritium, helium and other tracers. Most of parameters were analysed on board, but some required analyses in laboratories on land.
