Entrainment in Saldanha Bay
Saldanha Bay is located lOOkm north of Cape Town, along the south western coast of South Africa, at a latitude of approximately 33° S. In 1975 major harbour works, including the construction of an iron ore jetty, divided Saldanha Bay into two distinct bays. The bay to the north of the jetty has …

The characterisation of synoptic circulation patterns in Saldanha Bay
Saldanha Bay, on the west coast of South Africa, is the only deep water port between Cape Town and Walvis Bay. It is separated into two smaller bays, Small Bay and Big Bay, by an iron-ore jetty built in 1975. With its sheltered environment it is an ideal site for the development of a mariculture …

Long-term changes in the benthic macrofauna of Saldanha Bay
Saldanha Bay, which lies on the west coast of South Africa, has undergone major development over the last 30 years, including breakwater and harbour construction, harbour extension, dredging, mining, fishing, fish-processing and mussel culture. The aims of this study were to determine whether the …

Seaweed diversity in Saldanha Bay and the effects of human activities
… on the seaweeds of the west coast including the Saldanha and Langebaan System, but none has looked at how human activities may have affected the seaweed diversity of Saldanha Bay. The major human activities in the Bay include shipping and mariculture. The major human impacts resulting from these …

Nitrogen environment, ecophysiology and growth of Gracilaria gracilus in Saldanha Bay, South Africa
The growth of Gracilaria gracilis (Stackhouse) Steentoft, Irvine et Farnham was examined by studying the effect of organismic determinants such as thallus length, position along the thallus and branching in a series of in situ and laboratory-based experiments. Knowledge of these factors is …

Regional Spatial Development Framework for Saldanha Bay Municipality: Pursuing a more Ecologically Integrated Future
… profoundly influences the structure and form of Saldanha Bay Municipality. This is based on the premise that nature is not situated at the forefront of development and is not adequately addressed in spatial planning - our relationship with nature needs to change. Strategic spatial planning is a …

An ADCP study of subtidal scale density-driven exchange in Saldanha Bay, South Africa
… of subtidal-scale, density-driven exchange in Saldanha Bay, South Africa. Density-driven exchange conditions develop in response to synoptic-scale wind events in the southern Benguela region, even under light (<5m s-') wind conditions. During a density-driven exchange event, directionally …

Saldanha Bay as a living space: negotiating (re)source dynamics in a water scarce Bay
Saldanha Bay, South Africa's second busiest port, exists as a complex set of living systems, poised at the interchange between land and water. Because of its role as a port city, it is a place where water systems, transport routes, and industrial activity meet and intermingle. This thesis focuses …

Geology of Aeolian and marine deposits in the Saldanha Bay region, Western Cape, South Africa
… of the evolution of coastal deposits in the Saldanha Bay area, along the southern part of the west coast. The environments investigated comprise lagoons, coastal dunes and shorelines. The ages of the deposits were obtained with radiocarbon dating, strontium isotope stratigraphy and …

Some aspects of the nitrogen nutrition and growth of Gracilaria gracilis grown by suspended cultivation in Saldanha Bay, South Africa
… Growth of raft-cultivated Gracilaria gracilis in Saldanha Bay is known to be badly affected in late summer due to the persistence of warm oligotrophic water at the ocean surface which prevents replenishment of nutrients by upwelling. This study documents the extent of nitrogen starvation during …

Circulation through the mouth of Langebaan Lagoon and implications
… survey was conducted in Langebaan Lagoon and Saldanha Bay. The aim of this survey was to farther our understanding of the processes driving the mixing and the exchange at the Langebaan Lagoon-Saldanha Bay interface. The parameters measured included currents, water-levels, temperature, …

A geochemical investigation of the sediments in Small Bay, Saldanha Bay, with special reference to the mobility of Cd, Cu, Pb and Zn
Saldanha Bay is a natural deep-water harbour situated on the Cape West Coast, approximately 100 km north of Cape Town. The bay is not an estuary, since there are no rivers or streams entering the inlet. Saldanha Bay covers a total area of approximately 9.61 x 107 m2 and consists of three …

The effect and conservation implications of the re-establishment of a Cape fur seal Arctocephalus pusillus pusillus breeding colony at Vondeling Island, Saldanha Bay
… fur seals ranged eastwards up to Plettenberg Bay, where another core area was identified. Thus, Cape fur seals can traverse further from the breeding colony during times of poor feeding conditions in the vicinity of their breeding colony. By deduction, Cape fur seals will outcompete African …

Investigation of the role of the extracellular β-agarase, produced by the bacterial epiphyte Pseudoalteromonas sp. LS2i, in the virulence response towards the agarophyte Gracilaria gracilis
Gracilaria gracilis that grows naturally at Saldanha Bay, South Africa is economically important as a source of agar. The Gracilaria yields from natural beds at Saldanha Bay are however unreliable, and consequently the South African Gracilaria industry has experienced a number of setbacks over the …

The taphonomy of a micromammalian faunal assemblage from the Saldanha Bay Yacht Club : a contribution to the study of the South African west coast palaeoenvironments
… from a rich Terminal Pleistocene site near the Saldanha Bay Yacht Club (SBYC) along the South African west coast have been examined following Andrews' (1990a) procedures. In the investigation of the effect of taphonomy on the SBYC faunal remains, murids (rodents) and soricids (shrews) have been …

A biological study of the cellular response to heat stress in the South African alga Gracilaria gracilis
… from the wild South African population in Saldanha Bay as a feed for marine organisms and as a source of commercially important agar. Since 1974 however, a number of sporadic population collapses has lead to the destruction of this once flourishing resource. After numerous failed attempts …
