This West Coast Cetacean Distribution and Abundance Survey was conducted on the Ellen Kuzwayo Voyage 126, from 28 October to 10 November, 2014. The survey was planned for the region between Dassen Island and Groenriviermond up the west coast. The cruise track of the Ellen Kuzwayo is closely linked to that of the Algoa and while the latter was engaged in offshore and onshore parallel tracks up to the 250m isobaths, the former ran a saw tooth grid survey starting inshore Dassen Island (moving progressively northwards) in-between the parallel grids of the Algoa up to the 150m isobaths (unless concentrations of whales were sighted further offshore by the Algoa). Surveys will be conducted at 10 knots unless weather conditions and safety required a reduction in speed. In such cases all the sightings will be recorded as secondary sightings. The data are currently being analysed and the authors will be publishing a paper on it once that is completed, after which it will be made available....
This dedicated West Coast Cetacean Distribution and Abundance Survey was conducted on the Algoa Voyage 188 from 10 to 20 November, 2011.The main objective of this cruise was to develop and test approaches to a dedicated cetacean cruise. This objective, along with the research aims and proposed methodologies are consistent with internationally acceptable protocols. This work provided hands on experience of logistical and technical cetacean specific problems with dedicated cetacean cruises. This cruise was conducted from the Algoa and two smaller boats. This work precluded the long-term monitoring surveys that were conducted annually from 2012.
