Sardine, Hake, and Anchovy Recruitment Programme (SHARP) / St. Helena Bay Monitoring Line (SHBML) on the Africana Voyage 280, February 2012

At the intiation of the original SARP project the operational objective was to investigate variability in the transport of clupeoid eggs and larvae by the Benguela jet current from the south coast spawning grounds to the west coast nursery area as this would impact recruitment, thereby influencing the abundance of pelagic resources. To date 17 years worth of data have been collected on a transect perpendicular to the coast off Slangkop, the SARP line. Many valuable conclusions have been...
