  • Acoustic observations of jellyfish in the Namibian Benguela 

    Brierley, Andrew S.; Axelson, Bjorn Erik; Buecher, Emmanuelle; Sparks, Conrad A.J.; Boyer, Helen; Gibbons, Mark J. (Inter-Research, 2001)
    Multi-frequency acoustic data (18, 38 and 120 kHz) were collected in conjunction with pelagic trawl sampling for gelatinous macrozooplankton during a cruise to the Namibian Benguela in September 1999. Sampling focused ...
  • In quest of contact: phylogeography of helmeted terrapins (Pelomedusa galeata, P. subrufa sensu stricto) 

    Vamberger, Melita; Hofmeyr, Margaretha D.; Ihlow, Flora; Fritz, Uwe (PeerJ, 2018)
    Based on rangewide sampling and three mitochondrial and two nuclear markers (together up to 1,850 bp and 1,840 bp, respectively), we examine the phylogeography of two helmeted terrapin species (Pelomedusa galeata and P. ...
  • A new species of Magelona (Polychaeta: Magelonidae) from southern Namibia 

    Clarke, Dylan T.; Paterson, Gordon L. J.; Florence, Wayne K.; Gibbons, Mark J. (Iziko Museums of Cape Town, 2010)
    A new species of Magelonidae, Magelona debeerei sp. nov., is described and illustrated from grab-samples collected at <100moff the southwest coast of Africa. Magelona debeerei sp. nov. has previously been identified from ...
  • Towards the acoustic estimation of jellyfish abundance 

    Brierley, Andrew S.; Boyer, David C.; Axelson, Bjorn Erik; Lynam, Christopher P.; Sparks, Conrad A.J.; Boyer, Helen; Gibbons, Mark J. (Inter-Research, 2005)
    Acoustic target strengths (TSs) of the 2 most common large medusae, Chrysaora hysoscella and Aequorea aequorea, in the northern Benguela (off Namibia) have previously been estimated (at 18, 38 and 120 kHz) from acoustic ...
