Abstract	This is raw chlorophyll a data from Niskin Bottles from the Integrated Ecosystem Programme: Southern Benguela on the Algoa Voyage 202, 9 to 19 September, 2013.This was the pilot cruise for the IEP:SB for site determination and gear testing.The Integrated Ecosystem Programme: Southern Benguela is a multi-disciplinary, multi-institutional platform to undertake relevant science in the Southern Benguela; also functioning as a platform for collaboration and learning. All projects aim to develop an ecosystem indicator that can be used to effectively monitor and understand the Southern Benguela i.e physical, chemical, planktonic, microbial, seabird and benthic ecosystem indicators, used for ecosystem-based management.
Methods	This dataset was derived from discrete Chl-a data from the RV Algoa Voyage V202, 10 September 2013 - 16 September 2013. The following fluorometric chlorophyll sampling and analysis procedure was followed:- Tapped 200ml 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).
