Hydrothermal plumes and processes in Indian Ocean
The predicted cycling of the whole ocean through hydrothermal plumes is comparable to the mixing time of the oceans (few thousand years). Hence, understanding hydrothermal plume processes is crucial if their impact on the global geochemical cycles of elements is to be assessed. One of the most …

The Indian Ocean trade and the Roman State
Imperial Roman trading activity within the Indian Ocean has received increasing attention from scholars during the last few decades, much of it considering the role played by the Roman state. These studies have convincingly shown that state involvement was motivated, primarily, by the lucrative …

Simulation of variability in the tropical Western Indian Ocean
The oceanic circulation and properties in the Tanzanian shelf region in the tropical western Indian Ocean have been studied in this thesis using a regional ocean model. The study investigated the influences of the Northeast Madagascar Current (NEMC) in the Tanzanian shelf waters at the annual …

Is the Indian Ocean MOC driven by internal wave breaking?
… dissertation investigates the energetics of the Indian Ocean Meridional Overturning Circulation (MOC) using hydrographic data (Part I), and the interaction between a broad band internal wave field and a mean flow using idealized numerical simulations (Part II). The main objective of this work is …

Environmental influences on tuna movement patterns in the Indian Ocean
The Indian Ocean Tuna Commission conducted a small-scale tagging programme (2002-2009) and also a large-scale tagging programme: the Regional Tuna Tagging Programme of the Indian Ocean (RTTP-IO, 2005-2009). Both tagging programmes known as the Indian Ocean Tuna Tagging Project (IOTTP), targeted …

Microbial biodiversity in the southern Indian Ocean and Southern Ocean
… to perform basin wide physical and chemical oceanographic assessments in tandem with microbiological screening with the majority of studies only looking at a single component of the microbial community. In this study the full microbial diversity, from viruses to protists, was characterised …

Ocean model diagnosis of variability in the South Indian Ocean
… temperature (SST) variability in the South Indian Ocean may significantly influence weather and climate patterns in the southern African region. SST, in tum, can be influenced by variability in ocean fluxes, observations of which are limited in the South Indian Ocean and it is necessary to …

Composite structure of tropical cyclones in the SW Indian Ocean
This work examines SW Indian Ocean tropical cyclone (TC) structure as a function of movement using ECMWF gridded data. Analyses of the mean summer climate for the period 1987 1992 shown that conditions conducive to the development ofTCs are present between the latitudes 5° and 15°S. Six westward …

The geochemistry and petrology of the Rodrigues Ridge (Western Indian Ocean)
… located between 18°S and 20°S in the western Indian Ocean. The trend of the Rodrigues Ridge is contrary to the ocean floor fabric of the underlying crust, which formed on the Central Indian Ridge (CIR) between ca. 48 My and 10 My. Dating of dredged basalts from the Rodrigues Ridge showed them …

Influence of the Indian Ocean Subtropical Dipole on the Agulhas current
… SIOD climatology was developed using a Regional Ocean Modeling System (ROMS) configured with GFDL-CORE v.2b reanalysis winds and heat fluxes for the 1958-2007 period. This configuration allows for a relatively accurate spatial and temporal account of the Sea Surface Temperature (SST) and Sea …

A study of the phytoplankton of the South Western Indian Ocean
… studies in the past, data on that of the S.W. Indian Ocean has been almost entirely restricted to incidental references in the reports of expeditions which have passed through the area. Consequently, little has been known of the species composition and distribution of the phytoplankton, and …

A marine systematic conservation plan for Rodrigues Island, Western Indian Ocean
In 2007 the local government of Rodrigues gazetted four marine reserves in the north of the island based on knowledge and insights from stakeholders, mainly from the fishing community. In order to verify the stakeholder-based design, a marine reserve network was designed using Marxan, a systematic …
