Dataset: Nutrients, metals, and CTD observations from CTD casts and bottles from R/V Knorr cruise KN192-05 in the South Atlantic subtropical gyre and Benguela upwelling region from November to December 2007 (CoFeMUG project)

Analysis of nutrients, Cobalt (total and labile), dissolved Iron, and dissolved Manganese of water samples drawn from Trace Metal Rosette (TMR) bottle casts. CTD dataset is combined from both sensors. Missing CTD was due to lack of sensor package on the trace metal rosette (Stations 1, 25, 27, and some repeat Station 13 casts) or technical issues (battery failure, Station 9). Selected CTD depths (usually the deepest) were not included when O2 sensor values were anomolous (i.e. negative values).
