Estimating the upper ocean vertical temperature structure from surface temperature as applied to the southern Benguela

Includes bibliographical references.Underwater Sound Velocity Profiles (SVP) are used throughout the world by their respective navies for submarine and surface vessel strategic operations and exercises. Together with the sonar equations, the sound velocity profiles are of paramount importance to solve underwater sound detectability problems as they provide insight into the highly variable sound transmission loss. Oceanographic records of sea temperature-depth profiles are ordinarily incorporated into a sonar propagation model to determine the sound level at any point (range and depth). The ability to predict these environmental conditions with a defined level of confidence and accuracy significantly increases the situational awareness to in-theatre naval operators and fleet planners. The hypothesis in this thesis is that thermal characteristics of the water column in the southern Benguela can be numerically modeled and deduced from a single Sea Surface Temperature (SST) value, if provided with sufficient historic temperature-depth profiles for that region. For operational use, the SST would ideally be provided from near real time remotely sensed satellite derived data

Sea water quality and processes in Simon's Bay

Bibliography: leaves 152-159.The continued sustainable beneficial use of the sea, and in particular Simon's Bay, as an important industrial Naval Harbour, beach and recreational retreat, tourist destination, penguin haven, trek-net fishery, maritime archaeological area and research zone has been highlighted. If these benefits are to be maintained or in the context of expanded future use, then the quality of seawater in the region is seen as a key maritime health indicator of this interdependent system. Information about near-shore interaction with False Bay and beyond is important for good management. This work is primarily concerned with the marine coastal region defined by the port limits of Simon's Bay. Simon's Bay cannot, however, be studied, without consideration of the external influences of the greater False Bay and, still further afield, from the South Atlantic Ocean and the Agulhas bank The primary area of interest includes the port limits of Simon's Bay as defined by the South African Navy, depicted on the SAN 1017, 1998 Simon's Bay hydrographic chart. This work aims to provide an initial understanding of the spatial and temporal environmental dynamics of Simon's Bay and establish baseline values
