    Unique co-occurrence of two genera of cymothoid ectoparasitic isopods on the same individual fish host

    Item type: Journal Article • Journal: African Journal of Marine Science
    Parasitism of a host fish by a single species of cymothoid is regularly reported. For the first time on a temperate-fish host and in South African waters, we observed two species of cymothoids, the flesh-infesting Anilocra capensis and the tongue-infesting...

    The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Analysis of sea-level data obtained from the Atlantic Global Sea Level Observing System (GLOSS) sea-level station at Takoradi, Ghana, West Africa, clearly reveals a tsunami signal associated with the Mw = 9.3 Sumatra earthquake of 26 December 2004 in the...
  3. Distribution and seasonality of cetaceans in tropical waters between Angola and the Gulf of Guinea

    Distribution and seasonality of cetaceans in tropical waters between Angola and the Gulf of Guinea

    Item type: Journal Article • Journal: African Journal of Marine Science
    The species richness, spatial distribution, seasonality and interspecific associations of cetaceans in tropical oceanic waters between the Gulf of Guinea and Angola were examined using 5 905.3 h of dedicated survey effort collected from 13 platforms of opportunity (geophysical vessels)...
  4. Cetacean research in the southern African subregion: a review of previous studies and current knowledge

    Cetacean research in the southern African subregion: a review of previous studies and current knowledge

    Item type: Journal Article • Journal: African Journal of Marine Science
    Cetacean research, in terms of the number of papers, and areas for which data are available, has expanded considerably in the southern African subregion in the past decade, especially in the South-West Indian Ocean. We review cetacean research within this...
  5. Long current to nowhere? — Genetic connectivity of <em>Jasus tristani</em> populations in the southern Atlantic Ocean

    Long current to nowhere? — Genetic connectivity of <em>Jasus tristani</em> populations in the southern Atlantic Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    The commercially exploited spiny lobster Jasus tristani has a disjunct distribution in the southern Atlantic Ocean, with populations occurring at the Tristan da Cunha Archipelago, Gough Island and on Vema Seamount. A distance of 2 000km separates Vema and the...
  6. Extension of PIRATA in the tropical South-East Atlantic: an initial one-year experiment

    Extension of PIRATA in the tropical South-East Atlantic: an initial one-year experiment

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Pilot (later termed Prediction) and Research Moored Array in the Tropical Atlantic (PIRATA) programme, developed as a multinational network by Brazil, France and the USA, has deployed and maintained an array of 17 Autonomous Temperature Line Acquisition Systems (ATLAS)...
  7. Yvette Christiansë's Oceanic Genealogies and the Colonial Archive: <em>Castaways</em> and <em>Generations</em> from Eastern Africa to the South Atlantic

    Yvette Christiansë's Oceanic Genealogies and the Colonial Archive: <em>Castaways</em> and <em>Generations</em> from Eastern Africa to the South Atlantic

    Item type: Journal Article • Journal: Eastern African Literary and Cultural Studies
    This article traces tropes of dispersal and continuity in Yvette Christiansë oeuvre as it performs a genealogical enquiry through oceanic spaces and in and out of the colonial archive. Revolving respectively around St Helena and the Cape, both the poetry...
  8. Extreme significant wave height climate in the Gulf of Guinea

    Extreme significant wave height climate in the Gulf of Guinea

    Item type: Journal Article • Journal: African Journal of Marine Science
    This article investigates spatio-temporal trends for different return periods of extreme significant wave height (SWH) in the Gulf of Guinea (GG), northeastern tropical Atlantic Ocean, based on a 37-year (1980–2016) wave hindcast. High-resolution reanalysis windfield datasets were used to force...
  9. Early detection of nitrogen deficiency in wheat at different times of N application by using spectral reflectance of crop canopy

    Early detection of nitrogen deficiency in wheat at different times of N application by using spectral reflectance of crop canopy

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Physiological changes resulting from nitrogen limitations can be translated into clear spectral differences between treatments, demonstrating the relationship between leaf reflectance and leaf chlorophyll and nitrogen concentrations. A wheat trial was conducted in which nitrogen (N) was applied in the...
