Deployment: KN192-05

2007-11-16 - 2007-12-13 South Atlantic subtropical gyre and Benguela upwelling region Platform:R/V Knorr (vessel)

Description

The South Atlantic subtropical gyre and Benguela Upwelling region were sampled for chemistry and biological properties relating to the trace metal nutrition and phytoplankton diversity and productivity. Specifically cobalt and iron dissolved seawater concentrations will be measured and related to the abundance of cyanobacteria including nitrogen fixers and eukaryotic phytoplankton. The phytoplankton of the Benguela Upwelling region were also examined to determine if their growth was iron or cobalt limited. A total of 27 station locations were occupied in the study area to collect the water chemistry and biological samples for these analyses (see cruise track). Iron and cobalt analyses will be conducted using inductively coupled plasma mass spectrometry and cathodic stripping voltammetry electrochemical methods. The sample preparation and subsequent analyses are technically demanding, but data generated from the cruise samples are being contributed beginning in mid 2009.

The CoFeMUG KN192-5 cruise was supported by NSF OCE award # 0452883

A station map showing the 27 sampling locations is available as a PDF file.

Original cruise data are available from the NSF R2R data catalog
