The post holder will specifically work to generate a series of reconstructive models of 3D ocean biogeochemistry through the Phanerozoic (last ~540 million years). A key focus of this role is to explore uncertainty in three-dimensional ocean biogeochemistry over this time interval and its implications for geochemical proxy records and marine ecosystems. 

This is a relatively short-term, specialist Earth system modelling position (15-month duration). The post holder is therefore expected to have prior experience in intermediate complexity Earth system modelling and experience integrating key components of Earth system evolution on these timescales, or a strong track record in developing and deploying new skills in computational Earth Science research. 

The successful candidate will either hold, or be nearing completion of, a relevant PhD/DPhil and will have appropriate research experience alongside strong subject-specific expertise. They should be capable of working independently within established research programmes, managing their own research activities and contributing to academic publications. Strong communication skills are essential, including the ability to present research ideas and findings clearly, as well as representing the research group effectively in meetings and collaborative discussions.

Salary: £36,636 to £43,482 Per annum
Full Time Fixed Term for 15 months

Applicants should have a PhD* or equivalent in biological oceanography / marine biogeochemistry (or a related field). You would be expected to undertake sample and data analyses originating from the recent research expedition associated with the project and disseminate key aspects of the research project related to phytoplankton ecophysiology, trace element supply and biogeochemical cycling. Knowledge or experience of at sea observational and/or experimental work, or data analysis thereof, related to phytoplankton/microbial ecology/physiology and trace elements would be advantageous. Strong quantitative and communication skills, and the ability to conduct innovative research resulting in publications in international refereed journals are essential.

The successful applicants will be provided with a supportive and rewarding environment for further development of their knowledge, skills and experience, including through working as part of a large interdisciplinary oceanographic team comprised of sea-going phytoplankton and zooplankton ecologists, nutrient and trace metal biogeochemists and experts in ocean modelling. Under the guidance and support of the project (co-)PIs you will be encouraged to explore your own research interests, within the broader constraints of the overall project objectives. You will join a team led by Profs. Mark Moore, Maeve Lohan and Tom Bibby at SOES and will work closely with scientists at project partner institutions across the UK (Universities of Exeter, Liverpool, Plymouth and East Anglia and the National Oceanography Centre) as well as with our international partners. 

We are committed to creating an environment where everyone can thrive and aim to foster a culture of inclusion, respect and equality of opportunity within our consortium. We thus welcome candidates from any and all backgrounds who have an interest in the role and project. We particularly encourage applicants with characteristics that may currently be underrepresented in ocean sciences including, but not limited to, women, individuals from ethnic minority backgrounds, LGBTQ+ individuals and people with disabilities.

These positions are being offered on a full-time, fixed-term basis for 27 months. 

Informal enquiries can be made to Prof. C. Mark Moore on 023 8059 4801 or e-mail c.moore@soton.ac.uk and Prof Maeve Lohan on 0238059 5000 or e-mail m.lohan@soton.ac.uk.
