Abstract	The International Indian Ocean Expedition 2 (IIOE2) is a collaborative regional cruise to build capacity and strength within Africa. The focus will be on developing students in the region in the areas of physical oceanography, chemistry, biological oceanography, benthic biodiversity, marine top predators and marine plastics. This is processed Chlorophyll data from the IIOE2 cruise on SA Agulhas II Voyage 028, between the 14th October and 15th November 2017.
Methods	This dataset was derived from discrete Chl-a data from the SA Agulhas II Voyage 028 from 14 October to 15 November, 2017. Note that the fluorometer was only calibrated on the 27 September 2017 when it should have been calibrated before each cruise.The following fluorometric chlorophyll sampling and analysis procedure was followed:- Tapped 500ml sea water from CTD bottle into sampling bottle.- Filtered through a 2.5cm GFF at a vacuum not exceeding 30cm of Mercury.- Folded filter in half, encasing sample on the inside, using tweezers.- Wrapped in foil of a decent size to accommodate full identification.- Wrote identification clearly on the foil: Grid number and Depth.- Placed all the samples from a station, in order, in a plastic bag or foil wrap and labelled with Voyage No, Ships No and Grid No- Put in a labeled jar in the freezer.- Recorded the volume filtered next to the correct depth on both, the Phys/ Chem and biological deck chits.- Removed samples from jar and put samples into test tube and covered in acetone.- Placed test tubes into fluorometer to get chlorophyll value.- Applied calibration coefficient to the chlorophyll value based on the fluorometers calibration. Data and metadata is recorded in an excel spreadsheet from the relevant deck chits and instruments (fluorometer).
