The Integrated Ecosystem Programme: Southern Benguela (IEP:SB) was conducted on the Algoa Voyage 239 (ALG239) from 22 to 29 May 2017. This programme 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.
