We have received the sad news that Archbishop Desmond Tutu, the Nobel Peace prize laureate has died at age of 90. A man of extraordinary intellect, integrity and invincibility has passed away. He campaigned peacefully against apartheid, chaired the Truth and Reconciliation Commission after South Africa’s first democratic elections in 1994 and has worked tirelessly for peace in the world since his “retirement” as Archbishop of Cape Town.
In 2010, the University of Cape Town (UCT), the Nansen Environmental and Remote Sensing Center, the University of Bergen and the Institute of Marine Research in Bergen, Norway set up a joint venture. The venture, located at Department of Oceanography, UCT, was named the Nansen-Tutu Centre for Marine Environmental Research in honour and respect of two men – a Norwegian and a South African – who have demonstrated extraordinary passion for the natural environment and humanity.
Many of us had the inspiring opportunity to meet Archbishop Desmond Tutu at the inauguration of the Nansen-Tutu Centre in Cape Town in May 2010 ( photo above). His deep and inviting laughter was outstanding and signaled a man of welcoming warm, joy and curiosity. He manifested sincere concern for the changes in global climate and environment and their impact for society. The Nansen-Tutu Centre for Marine Environmental Research focusses on studying the Indian, South Atlantic and Southern Oceans and their impact on climate, weather and the marine ecosystem surrounding southern Africa and the training of the next generation African scientists.
The 10-years anniversary symposium in March 2020 targeted Ocean, Weather and Climate Sciences to the Service for Society and brought together almost 100 researchers, postdoctoral fellows, PhD, and MSc students to Cape Town, South Africa. Attendants came from Cameroon, Mauritius, Togo, Benin, Namibia, Mozambique, Madagascar, Tanzania, Kenya, Nigeria, Democratic republic of Congo South Africa, Ethiopia, France, Italy, Germany, Norway, Netherlands, United Kingdom and USA. Over the past 12 years the Nansen-Tutu Centre has gained numerous scientific achievements providing new knowledge about the ocean circulation surrounding Africa and the variability of African climate. This has been accomplished through research collaboration combined with training and supervision of graduate students and postdoctoral fellows. All in all, this capacity building has included more than 50 exchange visits and contributed to 18 graduations of master students, 10 graduations of PhD students and supported 9 postdoctoral fellows. The Nansen-Tutu Centre for Marine Environmental Research is greatly honoured to have the name of the joint venture associated with Archbishop Desmond Tutu. It is highly inspiring and stimulates us to aim for the joint venture´s vision to “Serve Africa through advancing knowledge of the marine environment and climate system in the spirit of Nobel Peace Laureates Desmond Tutu and Fridtjof Nansen”.

Tesha Toolsee from Mauritius was awarded her Master with distinction. She was advised by Tarron Lamont and Mathieu Rouault. Not only she submitted 6 months before the deadline she participated in the Marion Relief Voyage of 2021 where she received training in CTD operations and sampling around the Prince Edward Islands. She helped with the retrieval and deployment of two moorings on the inter-island shelf and also helped deploy surface drifters, spotters and Argo floats on the way to and back from Marion Island. She also managed to find the time to write a paper from her honor thesis already cited a couple of time. Toolsee, T, Lamont T., Ansorge A. and Rouault M. (2021). Characterising the seasonal cycle of wind forcing, surface circulation and temperature around the sub-Antarctic Prince Edward Islands, African Journal of Marine Science. 43(1), pp.61-76.
Liisa Shangheta from Namibia was awarded her Master. She was advised by Isabelle Ansorge Tarron Lamont and Mathieu Rouault and made the UCT news. As reported bt the UCT news teamn she saw the sea for the first time at age 14, on holiday with friends who took her to Henties Bay, Swakopmund and Walvis Bay. After the long journey west, Shangheta said, she became aware of a transition in the landscape: red sand dunes appeared, and beyond that, a ribbon of blue that stretched as far as she could see. And then came the smell of ozone off the ocean, or efuta, as the sea is called in her mother tongue, Oshikwanyama. “My tiny brain went ‘boom!’. It was just majestic. I was fascinated. I wanted to know why the waves continued breaking. What was happening here?” Read the all story here
After submitting her Master thesis in July 2021 (Master was actually passed with Distinction and thesis with minor corrections) physical oceanographer Sonia Heye is in Brest in France for two months to write a scientific paper with her French co-supervisor Pierrick Penven. After having completed her entire Masters thesis at home in isolation due to the covid pandemic, she is enjoying being back in an office and to be surrounded by other researchers and students. She is learning to work with the local servers and supercomputers and this trip is helping her to decide on the next steps in her scientific career. In the first week, she attended a conference in a nearby city, Roscoff. The hours at the office are very long and every day is getting colder with less daylight, but the beautiful nature of Brest is making it a very pleasant place to live.

Physical Oceanography MSc student, Kirstin Petzer, participated in the voyage of the SA Agulhas II to Gough Island this September/October 2021. The SA Agulhas II departed from the Cape Town Harbour on the 15th of September 2021, after a two week isolation period. Before reaching Gough Island on the 23rd of September the voyage stopped Tristan da Cunha Island to supply cargo and exchange personal. On board the vessel, Kirstin Petzer assisted the South African Weather Service (SAWS) team operating ocean and atmospheric observations and a team from the University of Pretoria using water filtration to reveal insights into micro-organisms in the South Atlantic, such as viruses and bacteria.
While the Gough Island exchange of personal was on going, Kirstin lead the collection of kelp samples at different sites around the island. The purpose and significance for the collection of the samples is for genomic analysis into the kelp species Macrocystis Pyrifera (Giant Bladder Kelp) and Durvillaea Antarctica (Southern Bull Kelp). The samples collected will be used as a biological reference for kelp species around the Island but also as indication of the movement of kelp which may reach the subantarctic Islands

The ongoing process of motivating a oceanographic cruise around Madagascar by Juliano
In September 2018, Juliano visited the Institute Marine Research (IMR), a focal point for the FAO-Nansen program, and Nansen Environmental and Remote Sensing Center (NERSC). The purpose of the trip was for presenting work he has been involved in publishing using the Dr Fridtjof Nansen data operated around Madagascar. The objective of the presentation was to motivate the FAO-Nansen program to invest more in the south-west Indian Ocean in terms of oceanographic campaigns.
Six months later, Juliano returned to spend two months, i.e. from March to April 2019, in Bergen Norway. Through this visit, Juliano sought to exploit the existing Dr Fridtjof Nansen data collected in the vicinity of the south of Madagascar, in order to again demonstrate that the cruise hydrographic measurement program can contribute significantly to resolving oceanographic mysteries occurring in the region. The study investigated the East Madagascar Retroflection behaviour (which remains unresolved at present), using mainly a compilation of Ship-mounted ADCP data from several cruises particularly from Dr Fridtjof Nansen program, and highlighted the local and the regional impact of the retroflection. The work has been done through collaboration between IMR and NERSC scientists.
Targeting a large audience working in the Indian Ocean rim and the FAO funders, Juliano also participated in the 11th Western Indian Ocean Marine Science Association (WIOMSA) symposium where he delivered an oral presentation and facilitated a panel discussion to raise awareness about and emphasize the need for Madagascar to be supported in collecting cruise data sets as much as possible for physical oceanography purposes which may have a local, regional and perhaps a worldwide impact.
Afterall, the job of a scientist does not always remain of as being only a researcher, but sometimes it requires more that we can afford!!!
Below: Juliano’s presentation during WIOMSA special session. Presentation title: “How and Where the East Madagascar Current originates?
Johnny Johannessen from NERSC visited for a week to teach operational oceanography and satellite remotes sensing while Marek Ostrowski from IMR spent a day at the Nansen Tutu Center on his way to a cruise.
Between the 6th and 8th of May, Michael Hart-Davis attended the EGI Conference on Advanced Cloud Computing in Amsterdam, Netherlands.

She is an oceanographer who is working with application and development of physical-biological models, including biogeochemical models, passive particle tracking studies and individual based models. Her research combines the model results with both in-situ and remotely sensed observations with the aim of studying the interaction between physical ocean processes and the marine ecosystems, the interaction between mesoscale eddies and the marine ecosystem is something finds particularly interesting. She has been employed at the Nansen Environmental and Remote Sensing Centre since 2005 where she has also been involved with developing operational oceanography applications for couple physical-biological models, this is now used as part of the CMEMS forecast for the Arctic. Since 2016 she has lead of the Ocean Modeling group at NERSC, which also collaborated with the Nansen Tutu Centre on the HYCOM modeling activity in the Agulhas region.
Welcome to our new research Associate Jenny. Dr Jennifer Veitch is a physical oceanographer who uses numerical models as a tool to better understand ocean processes that are difficult to observe in a cohesive way using in situ or satellite data. Her area of expertise is the Benguela system, from the Angola-Benguela Frontal Zone at its northern boundary to the Goodhope Jet at its southern. Jennifer has recently been appointed as a numerical modeller for a newly established initiative, funded by the Deaprtment of Environmental Affairs (DEA) and implemented by the South African Environmtenal Observation Network (SAEON), to promote transformative capacity building and development in ocean modelling in South Africa. In parallel to this, the vision is to produce an operational ocean modelling system for the South African coastline that will provide realtime information to various stakeholders.
Dr Halo from the department of conservation and marine science at CPUT, and currently research associate of the Nansen-Tutu Centre for Marine Environmental Research, was invited to attend a high level panel on "Building a Sustainable Ocean Economy" initiated by the Norwegian Prime Minister and comprising 13 Heads of Government and State and involving the United Nations (UN) Secretary-General Special Envoy for the Ocean. The objective was to leverage collective and effective action by the international community, including the UN, regional bodies, governments and private business, in response to global challenges and opportunities, along 6 main axis of research: (1) Impacts of climate change on marine ecosystems; (2) Ocean health; (3) State of fisheries resources; (4) Sustainable aquaculture; (5) Importance of seafood for human nutrition and (6) Future sustainable use of ocean biological resources. During the Oceans to Action meeting Dr. Halo moderated the table discussions of "Actions Points" compiled by the rapporteurs. Dr Halo then visited the Institute of Marine Research, and the Nansen Environmental Remote Sensing Centre (NERSC). During his visit to NERSC, he had several collaboration meetings with NERSC scientists and nearly finalized the writing-up of two joint research papers.
Bellinda Monyela and Belinda Nhesvure took part in the 4th Department of Science and Technology (DST) Global Change Conference hosted by University of Limpopo at Polokwane from the 3rd to 6th of December 2018. The theme of the conference was termed “Sustainable futures through science and innovation”. Bellinda Monyela presented her poster on Non El Nino drought in Southern Africa at the main conference while Belinda Nhesvure delivered an oral presentation on the impact of El Nino on coastal South African ocean e at the Alliance for Collaboration on Climate and Earth Systems Science (ACCESS) side event.
