The Centre’s research activities are grouped into 4 overarching themes and fits in various projects:

Ocean modelling and Prediction

Group coordinator: Annette Samuelsen

Co-investigators: Issufo Halo (CPUT), Francois Counillon (NERSC), Jennifer Veicht (SAEON)

Ocean modeling and prediction are crucial components of our research at the Nansen-Tutu Centre. We develop and utilize advanced computational models to simulate oceanic processes and forecast future conditions. These models help us understand complex ocean dynamics, such as currents, temperature distributions, and biogeochemical cycles. By improving our predictive capabilities, we can provide valuable insights into marine resource management, disaster preparedness, and climate change mitigation. Our work in ocean modeling also supports international collaborations, enhancing global efforts to monitor and protect the world’s oceans. Through continuous refinement and application of these models, we strive to deliver accurate and actionable data.

Ocean-Atmosphere interaction, Climate Variability, Regional Impacts

Group coordinator: Babatunde Abiodun (NTC/UCT)

Co-investigators: Marek Ostrowski (IMR), Noel Keenlyside (UIB), Founi Mesmin Awo (NTC)

Understanding the interactions between the ocean and atmosphere is essential for predicting climate patterns and their regional impacts. Our research focuses on studying these dynamic exchanges to reveal how they influence weather systems, climate variability, and extreme events. By examining phenomena such as Benguela Niño, cyclones, and marine heatwaves we aim to improve regional climate models and provide better forecasts. Our work also investigates the effects of climate change on ocean-atmosphere interactions, contributing to global climate science. By linking atmospheric conditions with oceanic responses, we can offer comprehensive insights into climate dynamics, which are vital for developing effective adaptation and mitigation strategies for vulnerable communities.

High Resolution Ocean Satellite Remote Sensing

Group coordinator: Marjolaine Krug (DFFE)

Co-investigators: Jonny A. Johannessen (NERSC), Morten Hansen (NERSC), Anton Korosov (NERSC)

The use of high-resolution satellite remote sensing technology allows us to obtain precise and detailed data about the physical and biological properties of regional seas. This cutting-edge approach enables us to monitor sea surface temperatures, chlorophyll concentrations, and ocean currents with great accuracy. By analyzing satellite imagery, we can track changes in marine ecosystems, identify upwelling and marine heat wave events, and detect harmful algal blooms. Our remote sensing capabilities also support climate research by providing data on sea ice extent, sea level rise, and other critical indicators. This technology enhances our ability to conduct large-scale environmental monitoring of the ocean.

Regional Sea Level Variability and Global Change

Group coordinator: Bernardino Nhantumbo (NTC/INAM)

Co-investigators: Bjorn Backeberg (Deltares), Johnny Johanessen (NERSC)

Investigating regional sea-level variability is crucial for understanding the impacts of global climate change on coastal areas. Our research at the Nansen-Tutu Centre focuses on identifying the drivers of sea-level changes, such as thermal expansion, glacial melt, and ocean circulation patterns. By analyzing long-term sea-level data and utilizing advanced modeling techniques, we can predict future sea-level trends and assess their implications for coastal communities. Our findings help inform coastal management plans, disaster risk reduction strategies, and climate adaptation policies. Understanding regional sea-level variability also contributes to broader climate change research, providing insights into global patterns and helping to address the challenges posed by rising seas.
