Paul Carnel _ Blue Carbon Lab

Paul’s research

Paul’s research aims to support government and non-government organisations to manage, protect and rehabilitate marine, coastal and freshwater ecosystems. This is done by:

  • Evaluating the ecosystem services (eg. blue carbon, coastal protection, fisheries) of marine, coastal and freshwater ecosystems, and how this varies in time and space
  • Utilising data on ecosystem extent, condition and services to create Environmental- Economic accounts that aim to optimise the benefits of nature through protection and restoration.
  • Developing effective and efficient monitoring programs that report against Limits of Acceptable Change in an Adaptive Management Framework

Underpinning these research goals, is experience in marine and freshwater ecosystems over the last 13 years. Here, Paul has established a career in aquatic ecology that allows him to merge pure and applied research via:

  • Strong field and laboratory research skills, having conducted research on many different ecosystems. During these projects, Paulhas conducted logistically difficult aquatic experiments involving over 450 logged scientific dives and more than 300 boat hours.
  • Paul’s experience working in experimental design and data analysis with Prof. Mick Keough has meant that he is both able to design and analyse robust research within the Blue Carbon Lab, but also have been sought out to analyse complex datasets for government departments.
  • Paul works effectively both independently and as part of team. This is evident in his experience in both leading individual projects and being involved in fieldwork and papers with groups of researchers.
  • Paul enjoys and is proficient establishing links with other researchers and stakeholders in his area of research. This is evident through collaborations on multiple projects.
