Gedurende die Grensoorlog het die Spesiale Magte se 4 Verkenningsregiment tientalle klandestiene seewaartse operasies saam met die SA Vloot uitgevoer. Van Cabinda in Angola tot Dar es Salaam in Tanzanië het hulle strategiese teikens soos oliedepots, vervoerinfrastruktuur en selfs Russiese skepe aangeval. Die bestaan van 4 Recce is grootliks geheim gehou, ook in die SAW.

Ystervuis uit die see beskryf 50 operasies deur 4 Recce, ander Spesmagte-eenhede en die SA Vloot. Daaronder tel Operasie Kerslig (1981), waartydens ’n operateur dood en ander beseer is in ’n aanval op ’n olieraffinadery in Luanda, en Operasie Argon (1985) toe kaptein Wynand du Toit in Angola gevange geneem is.

Die skrywers, wat self aan etlike van die operasies deelgeneem het, het ook toegang gekry tot uiters geheime dokumente wat intussen gedeklassifiseer is. Hul dramatiese vertellings wys hoe veelsydig en doeltreffend hierdie elite-eenheid was.

Die omvattende boek is ’n moet vir enigeen met ’n belangstelling in die Spesmagte. Dit neem jou na die hart van die aksie, die adrenalien en vrees van seewaartse operasies.

Recent developments in air pollution modelling are explored as a series of contributions from researchers at the forefront of their field. This newest contribution on air pollution modelling and its application is focused on local, urban, regional and intercontinental modelling; data assimilation and air quality forecasting; model assessment and evaluation; aerosol transformation. Additionally, this work also examines the relationship between air quality and human health and the effects of climate change on air quality. The work derives from a series of papers presented at the 33rd International Technical Meeting on Air Pollution Modelling and its Application held in Miami, USA, August 27 - 31, 2013.The book is intended as reference material for students and professors interested in air pollution modelling at the graduate level as well as researchers and professionals involved in developing and utilizing air pollution models."

From Cabinda in Angola to Dar es Salaam in Tanzania, 4 Reconnaissance Regiment conducted numerous clandestine seaborne raids during the Border War. They attacked strategic targets such as oil facilities, transport infrastructure and even Russian ships. All the while 4 Recce’s existence and capability was largely kept secret, even within the South African Defence Force.

With unparalleled access to previously top secret documents, 50 operations undertaken by 4 Recce, other Special Forces units and the South African Navy are described here in Iron Fist From The Sea. The daunting Operation Kerslig (1981), in which an operator died in a raid on a Luanda oil refinery and others were injured, is retold in spine-tingling detail. The book reveals the versatility and effectiveness of this elite unit and also tells of both the successes and failures of its actions. Sometimes missions go wrong, as in Operation Argon (1985) when Captain Wynand Du Toit was captured. This fascinating work will enthrall anyone with an interest in Special Forces operations.

Iron Fist From The Sea takes you right to the raging surf, to the adrenalin and fear that is seaborne raiding.

This volume contains the ten most cited articles that have appeared in the journal Atmosphere-Ocean since 1995. These articles cover a wide range of topics in meteorology, climatology and oceanography. Modelling work is represented in five papers, covering global climate model development; a cumulus parameterization scheme for global climate models; development of a regional forecast modelling system and parameterization of peatland hydraulic processes for climate models. Data rehabilitation and compilation in order to support trend analysis work on comprehensive precipitation and temperature data sets is presented in four papers. Field studies are represented by a paper on the circumpolar lead system. While the modelling studies are global in their application and applicability, the data analysis and field study papers cover environments that are specifically, but not uniquely, Canadian. This book will be of interest to researchers, students and professionals in the various sub-fields of meteorology, oceanography and climate science.

Comparison between The Full Edition of Iron Fist From The Sea and The Abridged Edition of Iron Fist From The Sea. A Number of the First Chapters cut in the abridged edition, so less background information. Certain Appendices have been Cut from the Abridged Edition. A Number of Military Operations have been cut. The Full Edition provides the whole operational history, whereas the abridged edition is lacking in background and much less detail on specific operations. This seminal work documents the clandestine seaborne operations undertaken by South Africa's 4 Reconnaissance Commando Regiment. It breathtakingly reveals the versatility and effectiveness of this elite unit which worked with a range of other South African and Rhodesian forces, including the Rhodesian SAS, to engage in a range of raiding and war fighting activities. These operations saw the clandestine reconnaissance of harbours, the sinking of enemy shipping and the destruction of shore installations in Angola and Mozambique. Just some of the tasks undertaken by this extraordinary maritime capability which totalled no more than 45 operators, both black and white! With unparalleled access to previously secret material, the authors, both of whom worked to develop 4 Recce's operating capabilities, trace the origins of the Regiment back to the 1970's when the South African's determined the need for a maritime force projection capability. They relate how maritime doctrine was developed within South Africa's wider Special Forces capability and how joint operational approaches were configured with the South African Navy. This saw the development of a range of swimmer, reconnaissance, diving and boat operator training courses, along with the design of specialist raiding craft and amphibious assault platforms, which were originated to operate from the Navy's existing shipping and submarines. All of which demonstrated the immense potential of this newly emergent force and the resourcefulness of its individual operators. Required to successfully complete a gruelling selection process, the operators of 4 Recce were relentlessly tested to prove their physical and mental mettle, not to mention their leadership skills and initiative. Steyn and Soederlund's chronological analysis of the operations undertaken by 4 Recce and the South African Navy is stunning to behold. They impartially detail the secret and specialised actions which saw both success and failure. From Cabinda on the West Coast to Tanzania on the East, 4 Recce, and whose existence and capability was largely kept secret even within the South African Defence Force, conducted numerous clandestine raids. They attacked shipping and strategic targets such as oil facilities, transport infrastructure and even ANC offices. And sometimes the raids did go wrong, spectacularly so in one instance when two operators were killed and Captain Wynand Du Toit was captured. He was later paraded in front of the world's media, much to the embarrassment of the South African government. This is a fascinating work and one that will enthral anyone with an interest in Special Forces operations. Profusely illustrated with many previously unpublished photographs, it stands as a testament to the author's endeavours as, respectively, the former Operations Commander of 4 Recce and the former Commander Task Group of the SA Navy - as well as the incredible operators of 4 Recce.
