The dynamics and physical processes of the Comoros Basin
The main objective of this thesis was to investigate the circulation in the ComorosBasin using observed and model datasets. These data were used to establish whether or not a Comoros Gyre exists and to investigate the nature of the eddy variability in the basin.The water masses in the Comoros Basin …

Physical Processes that Affect Hypoxia in the Thames River Estuary, USA
<p>Norwich Harbor is located at the head of the Thames River, the third largest drainage basin to the Long Island Sound. Hypoxic bottom-water conditions in Norwich Harbor have been documented during previous summers, but the evolution and variability of the low-oxygen levels have not been …

Identifying the dominant physical processes for mixing in full-scale raceway tanks
Biodiesels from microalgae are a promising alternative to fossil fuels with a number of unique benefits over other alternative fuel sources. However, to date, their viability in the fuels market remains infeasible due in part to a number of inefficiencies in the cultivation process. This has led to …

The Influence of Physical Processes in Galaxy Clusters on Observable Cluster Scaling Relations
… cosmological probes and laboratories for astrophysical processes. Cluster scaling relations, which connect their masses and observable properties, provide the link between these two roles. Cosmological constraints derived from cluster abundances often rely on calibrations or functional forms of …

On physical processes occurring in the hydrodynamic and magnetohydrodynamic astrophysical and laboratory flows
… rapidly growing and important part of the physical science. It appears that in many cases space and laboratory plasma can be well described in the framework of the hydrodynamics or magnetohydrodynamics. In the present study we shall investigate several types of hydrodynamic and …

Physical processes and zooplankton distribution in the Great South Channel : observational and numerical studies
… of a tightly integrated set of biological and physical observations made in the GSC by means of a new instrument, the Video Plankton Recorder (VPR); and a two-dimensional Eulerian numerical model that simulates one way in which a physical flow field, combined with a biological behavior pattern, …

Foraging ecology of the African Penguin Spheniscus demersus in relation to ocean physical processes.
This research demonstrated the dual utility of bio-loggers as a method for generating accurate, high-resolution oceanographic data. These data can be used in future studies, generating a cross disciplinary platform for research. The thesis augments our knowledge base of the African Penguins …

Temporal variability and vertical structure in larval abundance : the potential roles of biological and physical processes
… variability in planktonic larval supply and from processes occurring during and after larval settlement onto the seafloor. The focus of this thesis is on the temporal and spatial variability in larval supply, the extent to which planktonic larval distributions are determined by larval behaviors …

Integrated biological, chemical and physical processes kinetic model for the anaerobic digestion of primary sewage sludge
Despite its wide application, the design, operation and control of anaerobic digesters treating sewage sludges still is largely based on experience, or empirical guidelines. To aid the design, operation and control of (and research into) anaerobic digestion, a mathematical model would be an …

Multi-sensor mooring development and its use to characterise physical processes relevant to harmful algal bloom dynamics in the St Helena Bay area, South Africa
Harmful algal blooms (HABs), typically attributed to dinoflagellate species, occur along the west coast of South Africa, particularly during the latter part of the upwelling season. As part of the Benguela Current Large Marine Ecosystem (BCLME) programme, a buoy has been developed locally for …
