Claire is a plankton ecologist with 30 years research experience and over 70 publications relating to plankton biodiversity, community structure and ecosystem function. Specifically, Claire is highly skilled in phytoplankton identification and has studied planktonic communities in temperate (N&S Atlantic, North Sea), tropical (Indian Ocean, Mauritanian upwelling) and polar (Arctic & Antarctica) systems.
In 2005, Claire took over the responsibility for maintaining the long-term phytoplankton Station L4 time-series dataset which forms part of the Plymouth Marine Laboratory’s Western Channel Observatory. This programme has been running for over 30 years and is a key resource in Plymouth Marine Laboratory’s efforts to identify and predict the impacts of climate change on marine ecosystems.
Her current research combines traditional and pioneering technology, such as microscopy, automated image recognition and eDNA, to explore long-term trends in the diversity of phytoplankton communities, including harmful algal species (HABs), so as to quantify the potential impacts of climate change (weather extremes, rising temperatures and nutrient supply) on microbial communities.
