AbstractTable Bay, South Africa, is a typical headland-bay system with a shoreline that can be described by a logarithmic spiral. A peculiarity and unique feature of Table Bay is the juxtaposition of Robben Island opposite its headland. As a consequence, the bathymetry defines an ellipsoidal basin which was postulated to potentially resonate in the form of long-period standing waves (seiches). One aim of this study, therefore, was to investigate whether any evidence for such resonant oscillations could be detected in the geomorphology and sediment distribution patterns. Indeed, the ellipsoidal shape of the basin can be framed by two converging log-spirals with their centres located opposite each other, one off Robben Island and the other on the Cape Town side of the bay. The so-called apex line, which divides the two spirals into equal parts is aligned SW–NE, i.e. more or less parallel to the direction of ocean wave propagation. The distribution patterns of all sedimentary parameters were found to be characterised by a strikingly similar trend to either side of the apex line. This supports the hypothesis that the basin of Table Bay appears to resonate in the form of a mode 1 standing wave, with the node positioned above the apex line in the centre of the bay. The maximum period of such a standing wave was calculated to be around 37 min. The study demonstrates that large-scale sediment distribution patterns can reveal the existence of specific hydrodynamic processes in coastal embayments. It is recommended that this phenomenon be investigated in greater detail aimed at verifying the existence of resonant oscillations in Table Bay and, in the event, at establishing its precise nature and trigger mechanism.

“ROBBEN ISLAND IS A VERY SPECIAL PLACE in the new South Africa. No one in South Africa [and few elsewhere] refuses an invitation to come here“; with these words Justice Pius Langa, Vice-President of the South African Constitutional Court, aptly alluded to the symbolic significance of the place chosen as the venue for this first International Human Rights Academy. Indeed, it turned out to be quite an ingenuine idea on part of the Academy's organisers -namely Prof. Jeremy Sarkin from the University of Western Cape (UWC), Prof. Leo Zwaak from Utrecht University, and Prof. Johan Vande Lannotte from Ghent University, as well as Prof. Asbjorn Eide from the Norwegian Institute of Human Rights- to bring, for the first time ever, thirty-five participants from twenty-two countries to the place where Nelson Mandela served eighteen of his 27-years in prison and about which one of his fellow inmates, Ahmed Kathrada, who is now the Chairperson of the Robben Island Council, said that “we [the ex-prisoners] would want Robben Island to reflect the triumph of freedom and human dignity over oppression and humiliation, of courage and determination over weakness, of a new South Africa over the old”. As such, it was, perhaps, the ideal place to devote a good two-and-a-half-weeks (from April 3 to 20) to human rights in all their shades and colours.

The documentary film Prisoners of Hope (1995) is a heart-rending account of 1 250 former political prisoners in the notorious Robben Island prison in South Africa. The aim of this article is to explore the narratives of Prisoners of Hope and in the process capture its celebratory mood and reveal the contribution that the prisoners made towards the realisation of a free South Africa. The documentary features interviews with Nelson Rolihlahla Mandela, Ahmed Kathrada and other former inmates as they recall and recount the atrocities perpetrated by defenders of the apartheid system and debate the future of South Africa with its ‘new’ political dispensation led by blacks. A textual analysis of Prisoners of Hope will enable one to explore the human capacity to resist, commit oneself to a single goal and live beyond the horrors and traumas of an oppressive and dehumanising system.
