Dedicated cruise deepens offshore research capacity in South Africa

Dedicated cruise deepens offshore research capacity in South Africa

This week, a team of marine scientists will embark on a multi-institutional and multi-disciplinary offshore expedition to develop the capacity of young southern African scientists and to collect data in outer shelf and deep-sea habitats. 

The expedition is an excellent example of the teamwork needed to collectively understand, benefit from, and manage Africa’s oceans. Expedition team members span seven institutions and include experienced and emerging South African scientists, technicians, and students from seven institutes and four provinces. There is also a participant from Namibia who is a PhD student at the University of Cape Town expanding the impact of this first dedicated cruise to the broader southern African context.

Deep Capacity (Dedicated cruise deepens offshore research capacity in South Africa)

The expedition was designed by the emerging researchers and will contribute to several post graduate theses. It is led by young marine biologist, Luther Adams, who first joined the South African National Biodiversity Institute (SANBI) as an intern seven years ago. Adams will lead the team of young researchers in the One Ocean Hub Capacity Development Research Cruise from the port of East London.

“This expedition is allowing me to achieve a life-long dream to explore South Africa’s oceans and to use modern technology and new techniques to uncover the secrets that lie far beneath the sea surface,” says Adams.

The cruise is funded by One Ocean Hub, an international programme of research for sustainable development, working to promote fair and inclusive decision-making for a healthy ocean.

The One Ocean Hub brings together people and disciplines to learn from each other and collaboratively influence decisions and practices shaping the future of the ocean for justice and sustainability.

The cruise is an initiative of the Capacity Strengthening component of the Hub. Last year, hub researchers and their collaborators undertook a study to understand the challenges and solutions to develop capacity for deep-sea research and management in South Africa.

One of their recommendations was to hold dedicated in-country expeditions using available or locally developed technology under local conditions. This can provide relevant opportunities for more researchers and is a valuable addition to the more common approach where one or two scientists are able to participate in an international expedition with equipment that is usually not available in-country.  

Deep-sea Technology (Dedicated cruise deepens offshore research capacity in South Africa)

The expedition is facilitated by the South African Institute for Aquatic Biodiversity (NRF-SAIAB), a national facility of the National Research Foundation. The scientists are aboard NRF-SAIAB’s 15m Research Vessel Observer, skippered by Captain Koos Smith and supported by Ferdinand Jacobs.

The research gear includes a Remotely Operated Vehicle (ROV), deep-sea landers and oceanographic instruments. The ROV captures video and images and can collect biological samples using a manipulator arm.

Researchers will explore underwater caves and canyons and hope to find the elusive coelacanth which was first trawled off East London in 1938 but since then has only been seen much further north of Pumula and Sodwana Bay in KwaZulu-Natal and in other countries in East Africa.

Landers are remote underwater video stations that are baited and allow scientists to record fish, sharks and other deep-sea creatures attracted to the bait.

The team hope to deploy the landers to depths of up to 900 meters and it is the first time that such technology is being used below 363 meters in South Africa. Thembelihle Dube, a participating masters student from Rhodes University is particularly excited to see what fishes will be found in deeper waters.

‘’This expedition will provide our first glimpse of what’s happening beyond the shelf in this poorly studied region,’’ says Dube who hails from Richards Bay in KwaZulu-Natal.

Develop capacity (Dedicated cruise deepens offshore research capacity in South Africa)

The main aim of the cruise is to develop the capacity of a team of young researchers who can work together to solve the challenges of offshore research and management.

Research goals include the use of cutting edge genetic research to detect environmental DNA of threatened species, exploring patterns in invertebrate and fish biodiversity with increasing depth and work to understand the drivers of these patterns in the dynamic high current environment of the Amathole Offshore Protected Area.

The project also includes innovative, social and cultural aspects that recognise the deep human connections with the ocean and the team are working on understanding the use of marine species in medicine and ritual practices, including the identification and mapping of Culturally Significant Areas in the coastal and ocean environment.
