Abstract. Phytoplankton succession in relation to some physico- chemical characters of some water bodies at Jeddah Coast (Saudi Arabia) was studied for one year (2004). The sampling program included four different areas, North Obhour, Technology area, Down Town area and South Jeddah Area. Water samples were analyzed for some physico-chemical parameters (Temperature, pH, S‰, Dissolved +2 +2 Oxygen (DO), Calcium (Ca ) & Magnesium (Mg ), Nitrite (NO2), Nitrate (NO3), Ammonia (NH3), Reactive Orthophosphate (PO4) and Reactive Silicate (SiO3) as well as phycological parameters (Phytoplankton communities and Chlorophyll a). The Jeddah Coast was found to be oligotrophic ecosystem in some areas, while some of these areas were mesotrophic with high phytoplankton density such as the Down Town and South Jeddah areas. The results showed that, the high phytoplankton density attaining the maximum of 2623.2 X 103/m3 at Down Town area during spring and the minimum of 118.7 X 103/m3 at Technology area during winter. Seventy three species belonging to 73 genera and 5 groups were recorded. Dinophyceae was the first dominant group forming 43.8% of the total phytoplankton communities followed by Bacillariophyceae 27.9%. -

A Suggested Blueprint for the Development of Maritime Archaeological Research in Namibia Bruno E.J.S
Journal of Namibian Studies, 2 (2007): 103–121 ISSN: 1863-5954 A suggested blueprint for the development of maritime archaeological research in Namibia Bruno E.J.S. Werz Abstract During the last few decades, maritime archaeology has developed into an internationally accepted field of specialisation within the discipline of archaeology. It has, however, only gained academic recognition in Southern Africa since the late 1980s, when a lecturing post for maritime archaeology was established at the University of Cape Town. This resulted in initial efforts being focused on South Africa. Now, however, the time has come to expand the development of maritime archaeology to neighbouring countries. Due to various positive factors – including the presence of an important research potential as well as growing interest and positive contributions by some organisations and private individuals – Namibia provides a fertile ground to extend the field of operations. This article first summarises the objectives and methodology of maritime archaeological research in general; then it offers suggestions as to how to establish this research specialisation in Namibia, bearing in mind local circumstances. What is Maritime Archaeology? Maritime archaeology developed by means of an evolutionary process from underwater salvage, treasure hunting, the collecting of antiquities and the kind of archaeological work that was done until the early twentieth century. During the 1960s, the field became an area of specialisation within the discipline of archaeology. This period saw a growing involvement of professional archaeologists, the rudimentary development of research designs, the improvement of diving equipment, and the application of techniques that facilitated work in an underwater environment. The initial emphasis, however, was on the latter.1 As a result, the field did not obtain widespread support from its terrestrial counterparts, where efforts were generally directed at solving specific research problems. -

Population trends of seabirds breeding in South Africa’s Eastern Cape and the possible influence of anthropogenic and environmental change. Marine Ornithology 37: 159–174. Eleven species of seabird breed in South Africa’s Eastern Cape Province. Numbers of African Penguin Spheniscus demersus and Cape Gannet Morus capensis in the province increased in the 20th century, but penguins decreased in the early 21st century. A recent eastward displacement of Sardine Sardinops sagax off South Africa increased the availability of this food source to gannets but did not benefit penguins, which have a shorter foraging range. Fishing and harbour developments may have influenced the recent decrease of penguins. -

J.E.Afr.Nat.Hist.Soc. Vol.XXV No.3 (112) January 1966 CHECK LIST OF ELOPOID AND CLUPEOID FISHES IN EAST AFRICAN COASTAL WATERS By G.F. LOOSE (East African Marine Fisheries Research Organization, Zanzibar.) Introduction During preliminary biological studies of the economically important fishes of the suborders Elopoidei and Clupeoidei in East African coastal waters, it was found that due to considerable confusion in the existing literature and the taxonomy of many genera, accurate identifi• cations were often difficult. A large collection of elopoid and clupeoid fishes has been made. Specimens have been obtained from purse-seine catches, by trawling in estuaries and shallow bays, by seining, handnetting under lamps at night, and from the catches of indigenous fishermen. A representative fartNaturalof thisHistory),collectionLondon,haswherenow beenI wasdepositedable to examinein the Britishfurther Museummaterial from the Western Indian Ocean during the summer of 1964. Based on these collections this check list has been prepared; a review on the taxonomy, fishery and existing biological knowledge of elopoid and clupeoid species in the East African area is in preparation. Twenty-one species, representing seven families are listed here; four not previously published distributional records are indicated by asterisks. Classification to familial level is based on Whitehead, P.J.P. (1963 a). Keys refer only to species listed and adult fishes. In the synonymy reference is made only to the original description and other subsequent records from the area. Only those localities are listed from which I have examined specimens. East Africa refers to the coastal waters of Kenya and Tanzania and the offshore islands of Pemba, Zanzibar and Mafia; Eastern Africa refers to the eastern side of the African continent, i.e. -

Final Msc Thesis
THE ZOOGEOGRAPHY OF THE CETACEANS IN ALGOA BAY A thesis submitted in fulfilment of the requirements for the degree of MASTER OF SCIENCE of RHODES UNIVERSITY by BRIGITTE LEIGH MELLY January 2011 ABSTRACT The most recent study on cetaceans in Algoa Bay, South Africa, was conducted over 14 years ago. Consequently, knowledge of the cetacean species visiting this bay is currently based on incidental observations and stranding data. A number of developments in recent years: a deep- water port, proposed oil refinery, increased boating and fishing (commercial and recreational), a proposed Marine Protected Area, and the release of a whale-watching permit, all of which may impact these animals in some way, highlight the need for a baseline study on cetaceans. Therefore, the aim of this study was to determine the spatial and temporal distribution, and habitat preference of cetaceans in Algoa Bay. Boat-based surveys were conducted monthly between March 2009 and July 2010. At each sighting the GPS location, species, group size and composition, and behaviour were recorded. Using GIS, the sighting data was related to data layers of geographical variables such as sea surface temperature, depth and sea-floor substrate. Approximately 365 hours of search effort were completed over 57 surveys, with a total of 346 sightings. Species observed were: southern right whales (Eubalaena australis), humpback whales (Megaptera novaeangliae), Bryde’s whales (Balaenoptera brydei), Indian Ocean bottlenose dolphins (Tursiops aduncus), Indo-Pacific humpback dolphins (Sousa chinensis), and long- beaked common dolphins (Delphinus capensis). Southern right whales were observed during austral winter, utilising the shallow, protected areas of the bay as a mating and nursery ground. -
