Zone of the Aliwal Shoal Marine Protected Area (MPA).16 Basic biological inventory studies to determine the status of the reef are required for conservation and management planning of the MPA. This relies on reliable knowledge of the location and distri- bution of reef habitats. The bathymetry map of the Aliwal Shoal serves as a spatially accurate base map that is easily imported into a GIS database, where it can be used as a multi-surface attribute model for spatially referenced data. The dataset forms a base map for biological surveys to chart changes to habitats and biological zones and provides a means to model effluent discharge and environmental impacts from marine outfall pipe- lines situated north of the study area.

The new bathymetric map also indicates the presence of other shallow, isolated pinnacles that can be used as alternative dive sites, alleviating pressure on the more popular dive sites situated on the Crown. Recreational divers will benefit from the high accuracy of the map by planning the exact location of their dives and minimizing user conflict within the MPA. Furthermore, it is envisaged that these data will form part of an MPA website providing tourists and divers with geological, biological, and oceanographic information and 3-D ‘fly-through’ visualization.

The bathymetric dataset not only serves as the first accurate and detailed map of the Aliwal Shoal but also serves as a useful ‘environmental tool’ which will form the baseline for future studies ranging from the mapping of biological seafloor habitats to ocean current modelling. Integration of all the data types will facilitate the development of a comprehensive multidisciplinary environmental management plan, which is vital for the future development, management and conservation of the Aliwal Shoal.

The Southern African Research and Innovation Management Association offers two courses for members and stakeholders

Overview of the South African research and innovation system

To be held at the Stellenbosch Lodge, Cape Town, 3–5 October 2005

The presenters are Prof. Johann Mouton, Director of CREST, University of Stellenbosch, Prof. Anastassious Pouris, Institute of Technological Innova- tion, University of Pretoria, Prof. David Kaplan, Graduate School of Busi- ness, University of Cape Town, and Dr Eric Wood, Graduate School of Business, University of Cape Town. The course is targeted towards mid- and senior level managers of research, innovation and technology transfer offices in the academic, government, research agency and industry sectors.

sarima@sarima.co.za. On receipt of the registration form, an invoice will be sent for payment, prior to or at the event. Closing date for registration is 29 September.

Research administration and management in South African higher education institutions

To be held at the Protea Hotel, Stellenbosch, 6–8 October 2005

The objectives of the course are to develop the participants’ under- standing of: The transformational challenges facing research in higher education; The human resource requirements for research; The financial resources for research; The elements of effective administrative infra- structure for research; The elements of development plans for research.

The themes to be covered include: A short history of South African science, key policy documents in science and technology; The national system of innovation: Key facts and figures, An overview of the main insti- tutions in the science system; The Department of Science and Technology, National Advisory Council on Innovation, The Science Councils, The higher education sector, The national research facilities, The funding agencies, The Academies of Science, The CHE and HESA; The demographics of the R&D workforce; Key initiatives in science and technology; Key debates in science and technology; Challenges facing the SA science and technology system.

The course is aimed at professionals who work in research administra- tion and management offices in higher education institutions in South Africa and in organizations that deal with managers and administrators in these offices. Participants will typically not have received any formal training in research management or related fields. It is an introductory course but deals comprehensively with all aspects of research administra- tion.

The registration cost of R1900 for the three-day course includes a work- shop folder, reading pack and all meals. SARIMA members who have paid their subscriptions for 2005 are eligible for a 15% rebate (R1615).
