PhD Studentship: Seasonal Inorganic Carbon Dynamics at the Land-ocean Interface

University of East Anglia - School of Environmental Sciences

Start Date: October 2018

No. of positions available: 1

Supervisor: Primary supervisor: Dr Dorothee Bakker, Secondary Supervisors: Dr Martin Johnson, Prof Richard Sanders (NOC), Dr Naomi Greenwood (Cefas), Dr Silke Kroeger (Cefas)

Project description:
Rivers transport organic and inorganic carbon from land via estuaries to the oceans. Intense biological activity and mixing of freshwater and seawater lead to outgassing of carbon dioxide (CO2). Human activities may have increased this outgassing. Oceanic release of riverine carbon is a major uncertainty in the Global Carbon Budget.

This PhD research project has the objective to quantify how organic carbon degradation increases the dissolved inorganic carbon load and CO2 outgassing for UK estuaries and shelf seas. The project builds on the Land Ocean Carbon Transfer (LOCATE, programme, which aims ‘to estimate land-ocean carbon fluxes’.

You will collect carbonate chemistry samples on the R/V Cefas Endeavour, subject to a successful medical and sea survival training. You will carry out and interpret carbonate chemistry analyses on LOCATE samples from 20 UK estuaries in four seasons, as well as on year-round samples from SmartBuoys in the outer Thames and Wash estuaries and on North Sea-wide samples. You will use mixing lines of salinity versus carbonate parameters to determine carbonate chemistry transformations along the salinity gradient in UK estuaries and the North Sea. You will quantify how these processes drive estuarine and shelf sea CO2 outgassing.

This timely project of global significance includes training in seagoing research, chemical analyses and scientific data interpretation. You will collaborate with dynamic research teams at the University of East AngliaCefas, the National Oceanography Centre (NOC) and in LOCATE. You will be associated with the ENVEast Doctoral Training Programme. You will present your findings at (inter-)national scientific conferences, in peer-reviewed scientific publications and a PhD thesis.

Person specification: We seek an enthusiastic, pro-active team player with strong scientific interests and self-motivation. You will have at least a 2.1 honours degree in physics, chemistry, mathematics, computing, or a branch of environmental science.

Funding notes: 
This NERC Industrial Case studentship is in partnership with Cefas funded for 4 years.  An annual stipend (in 2017/18 the stipend is £14,553) will be available to the successful candidate who meets the UK Research Council eligibility criteria. These requirements are detailed in the RCUK eligibility guide which can be found at In most cases UK and EU nationals who have been ordinarily resident in the UK for 3 years prior to the start of the course are eligible for a full-award.  Other EU nationals may qualify for a fees only award.
