Abstract	This is raw Surface Photosynthetically Active Radiation (SPAR) data collected on the West Coast Cetacean Distribution and Abundance Survey on the Algoa Voyage 211, 28 October to 10 November 2014. The cruise operated on the shelf and slope regions off the West Coast of South Africa, between Dassen Island and Groenriviermond.The major objective of this cruise was to survey the abundance and distribution of cetaceans, in particular humpback whales, within the study area on the west coast. This objective, along with the research aims and proposed methodologies, are consistent with internationally accepted protocols. This work provided hands-on experience with logistical and technical cetacean specific problems associated with dedicated cetacean cruises. This work was a collaboration with the Mammal Research Institute, University of Pretoria, and the Department of Agriculture, Fisheries and Forestry.
Methods	Raw data in their original format, as received from the QSR-2000 Hemispherical Quantum Scalar Reference Sensor by Biospherical Instruments Inc. This sensor is designed for measuring total incident Surface Photosynthetically Active Radiation (SPAR) (400-700 nm) from the sun and sky. SPAR sensors are usually mounted on a vessel’s mast and the data can be used as a surface reference for underwater profiling PAR sensors.
