Author:Van Aken, HM; Lutjeharms, JRE; Rouault, Marjolaine J; Whittle, C; De Ruijter, WPMDate:Feb 2013The exchange of heat and salt between the South Indian Ocean and South Atlantic Ocean, at the southern terminus of the Agulhas current, forms a crucial link in the global ocean circulation. It has been surmised that upstream retroflections ...Read more
Author:Pivan, X; Krug, Marjolaine J; Herbette, SDate:Sep 2016This study reinvestigates the work of Lutjeharms et al. (2001, 2003) who documented the properties of a Natal Pulse using isopycnal Lagrangian floats. We combined Lagrangian analyses and Eulerian maps derived from objective analysis to better ...Read more
Author:Shillinglaw, SN; Pieterse, AJHDate:1977A dense algal population is of primary importance in sewage maturation ponds for the removal of plant nutrients, especially ammonia and orthophosphate. In the Republic of South Africa and in South West Africa sudden algal population declines ...Read more

Author:Davis-Reddy, Claire LDate:Oct 2017The body of work on historical climate trends has been steadily increasing during the last decade. Global mean annual temperatures have increased by 0.85°C since 1880 and are projected to increase by 0.3 to 2.5 °C by 2050, relative to the ...Read more
Author:Naidoo, Darryl; Ait-Ameur, K; Litvin, I; Fromager, M; Forbes, ADate:May 2012The mode inside a laser cavity may be understood as the interference of two counter-propagating waves, referred to as the forward and backward waves, respectively. We outline a simple experimental procedure, which does not require any additional ...Read more
Author:Krug, Marjolaine J; Cipollini, P; Dufois, FDate:Jun 2014The Agulhas Current is a challenging region for satellite remote sensing observations. Strong evaporation rates above the current core and the Retroflection reduce the number of cloud-free observations from Infra-Red sensors, while microwave ...Read more
