While the ocean takes up a quarter of the carbon dioxide (CO2) emissions from human activity, paradoxically newly formed Antarctic Bottom Water contains little of such ‘anthropogenic’ CO2, probably because sea ice hampers air-sea CO2 exchange. Sea ice also mediates relevant processes such as phytoplankton growth and surface mixing, while brine drainage from sea ice facilitates the transfer of carbon to depth.
1) Quantify ocean CO2 uptake by Antarctic waters,
2) Determine the role of sea ice and other drivers in this uptake and in carbon transfer to depth.
You will investigate the drivers of year-to-year variation in ocean CO2 uptake by carrying out carbonate chemistry analyses on seawater samples collected at the Rothera Time Series (West-Antarctic Peninsula), by calculating CO2 uptake and by placing your data in a context of the recent rapid decline in seasonal sea ice cover. If this interests you, you may determine the impacts of ocean acidification on local marine ecosystems.
You will also quantify the importance of sea ice for ocean CO2 uptake and carbon transfer to depth near the Larsen Ice Shelf, using data collected in February 2024 on the multiplatform, multidisciplinary PICCOLO (Processes Influencing Carbon Cycling: Observations of the Lower limb of the Antarctic Overturning) cruise. Data sets for air-sea CO2 fluxes, carbonate chemistry and diverse biological and physical variables will be available.
You will put your new data in a wider perspective using data from autonomous platforms, other ships and satellites.
- Be trained in chemical analyses;
- Develop skills in data analysis and programming (Python or Matlab);
- Join the dynamic PICCOLO and Rothera Time Series science teams;
- Present research at an international scientific conference and in peer-reviewed publications;
While working on a project of global significance. Fieldwork is not an integral part of this project, however, there might be opportunities to gain seagoing experience.
We seek an enthusiastic, pro-active team player with strong scientific interests, self-motivation and numerical skills. You will have at least a 2.1 honours BSc degree in chemistry, natural sciences, environmental sciences, physics, mathematics or similar numerical subject.
