PhD Bursaries at Stellenbosch University 2025 (in marine Carbon Dioxide Removal (mCDR))
Climate change is one of the most
pressing challenges of our time, and the need for innovative solutions to
mitigate its impacts has never been more urgent. Among the emerging strategies
to combat rising atmospheric carbon dioxide (CO₂) levels, marine Carbon Dioxide
Removal (mCDR) has gained significant attention. This approach leverages the
ocean's natural capacity to absorb and store CO₂, offering a promising pathway
to enhance carbon sequestration and reduce global warming.
Recognizing the importance of this field, the
School for Climate Studies at Stellenbosch University, in collaboration with
the Southern Ocean Carbon Climate Observatory (SOCCO) at CSIR, the Department
of Forestry, Fisheries, and the Environment (DFFE): Oceans and Coasts Branch,
the South African Environmental Observation Network (SAEON), and the University
of KwaZulu-Natal (UKZN), is launching a groundbreaking research program. This
initiative aims to address South Africa’s science, technology, and policy needs
in mCDR and is offering three exciting PhD bursaries for aspiring researchers.
The three PhD bursaries, set to run
from 2025 to 2027, focus on critical themes within mCDR, each addressing unique
aspects of ocean carbon dynamics and their implications for climate resilience.
These opportunities not only provide a platform for cutting-edge research but
also offer a chance to contribute to regional and global climate science.
Below, we delve into the details of each bursary, the skills required, and the
broader significance of this initiative.
1. Development of a Coastal Ocean Carbon Observatory
The first bursary focuses on understanding how sub-tropical East coast estuarine systems modulate carbon fluxes between land and ocean. Estuaries are dynamic environments where freshwater from rivers meets seawater, creating complex biogeochemical processes that influence carbon cycling. This project aims to establish a coastal ocean carbon observatory to monitor and analyze these processes, providing critical insights into how estuarine systems contribute to carbon sequestration.
Skills and Interests:
Applicants should hold an MSc in
quantitative oceanography, estuarine biology, or biogeochemistry. Experience in
fieldwork and laboratory analysis of water samples is essential, as is
proficiency in data analysis using tools like R. Familiarity with ecosystem
modeling would be an advantage. This project is ideal for candidates with a
passion for understanding the intricate relationships between land, ocean, and
climate.
Significance:
By developing a coastal carbon
observatory, this research will enhance our understanding of carbon fluxes in
sub-tropical regions, which are often underrepresented in global carbon cycle
studies. The findings will inform strategies to optimize natural carbon sinks
and support South Africa’s climate resilience efforts.
2. Scale Sensitivity of Uncertainties in CO₂ and Climate Observations
The second bursary addresses the
challenge of minimizing uncertainties in CO₂ and climate observations in South
Africa’s coastal and oceanic zones. This project will combine existing and new
oceanographic data from ship-based and robotic experiments with model-based
simulations and machine learning tools. The goal is to improve the accuracy of
long-term carbon and climate observations, which are critical for predicting
future climate scenarios.
Skills and Interests:
Candidates should have an MSc in
physics or mathematics, with training in oceanography being an advantage.
Proficiency in numerical analysis and Python coding is essential, as is an
interest in applying machine learning methodologies to environmental data. This
project is suited for individuals who enjoy tackling complex problems through
computational and analytical approaches.
Significance:
Accurate observations and
reconstructions of CO₂ and climate data are vital for understanding the impacts
of climate change and developing effective mitigation strategies. By reducing
uncertainties in these observations, this research will contribute to more
reliable climate models and inform policy decisions at both regional and global
levels.
3. Impacts, Feedbacks, and Risks of Scalable mCDR Strategies
The third bursary explores the
potential impacts, feedbacks, and risks associated with scalable mCDR
strategies, such as ocean afforestation and alkalinity enhancement. These
approaches aim to enhance the ocean’s capacity to absorb CO₂, but their large-scale
implementation requires a thorough understanding of their ecological and
biogeochemical consequences. This project will combine modelling and
observational experiments to assess the feasibility and risks of these
strategies in South Africa’s regional and coastal ocean systems.
Skills and Interests:
Applicants should have an MSc in
physics or mathematics, with a background in oceanography being advantageous.
Proficiency in numerical analysis and Python coding is essential, as is an
interest in machine learning. This project is ideal for candidates who are
passionate about exploring innovative climate solutions while considering their
broader environmental implications.
Significance:
As mCDR strategies gain traction, it
is crucial to evaluate their potential impacts on marine ecosystems and coastal
communities. This research will provide valuable insights into the risks and
benefits of scalable mCDR, guiding the development of sustainable and equitable
climate mitigation strategies.
Why This Opportunity Matters
The three PhD bursaries offered by Stellenbosch University and its partners represent a unique opportunity to contribute to the growing field of mCDR. Each project addresses a critical gap in our understanding of ocean carbon dynamics, offering the chance to make meaningful contributions to climate science and policy. Beyond the academic and research benefits, successful candidates will have access to international exchange programs, summer schools, and skills development support, fostering a well-rounded and globally connected research experience.
This initiative also aligns with
South Africa’s commitment to equity and transformation in higher education. By
prioritizing candidates who reflect the diversity of the country, the program
aims to build a new generation of climate scientists who can address the unique
challenges faced by South Africa and the broader African continent.
