Applications accepted all year round

Applications are invited for a 3-year self-funded PhD.

The PhD will be based in the Faculty of Science and Health, and will be supervised by Dr Federica Ragazzola, Dr Sarah Reynolds and Dr Marianna Cerasuolo.

The work on this project will involve:

  • Characterisation and distribution of the seagrass meadows in the Solent (UK)
  • Quantification of the blue carbon stock of the meadows
  • Modelling the meadows' carbon stock under future climate conditions

Human actions have increased carbon dioxide concentrations in the atmosphere to levels higher than any measured in the past 160,000 years. Carbon sequestration by natural systems may be a solution for slowing down atmospheric CO2 increases. The sequestration of carbon into ocean sediments by marine ecosystems for long-term storage is termed blue carbon. Compared to terrestrial carbon storage, whose accumulation is very slow and can be easily released (e.g. by fires), blue carbon can provide CO2 sequestration from the atmosphere for decades to millennia.

Seagrass meadows are one of the main carbon sinks in marine coastal environments. They are important ecosystem engineers and provide various ecological services. In addition to providing crucial habitat for a range of fish and invertebrate species, seagrass meadows also promote a range of environmental benefits such as sediment stabilization, wave attenuation, increased water quality and light availability. They also represent an important economic asset. For instance, seagrass is estimated to generate approximately $1.9 trillion per year in the form of nutrient cycling. Moreover, it is estimated that globally as much as 19.9 Pg of organic carbon is stored in the meadows (blue carbon).

The aim of the project is to assess the blue carbon storage capacity of the seagrass meadows in the Solent. The Solent is a unique area because of its unusual tidal regime, including double tides and long periods of tidal stand at high and low tide. It is composed of extensive intertidal mudflats, sandbanks, coastal lagoons and grazing marsh hosting a rich wildlife. These vital carbon sinks will lock carbon away from rising atmospheric contributions of CO2, thereby mitigating climate change, particularly by suppressing ocean acidification. Once the blue carbon storage capacity is determined from field sampling and chemical analyses, future changes in blue carbon storage and habitat distribution under different climate change scenarios will be modelled.

Entry requirements

Entry requirements

You'll need an upper second class honours degree from an internationally recognised university or a Master's degree in an appropriate subject. In exceptional cases, we may consider equivalent professional experience and/or qualifications. English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0.

We are looking for a talented and enthusiastic student with a strong background in marine biology, environmental sciences or marine plant/macroalgae physiology. Knowledge of data visualisation tools (i.e. GIS) and experience in modelling is also desirable but not essential.
