Sarah is exploring the role anthropogenic greenhouse gas emissions play in changing the risk in developing regions, based on an analysis of climate scenarios, hydrological impacts and resulting damage estimates.
I work as part of the Arctic PRIZE (Productivity in the Seasonal Ice Zone) research project, which aims to improve understanding of how seasonality and climatological variables, such as sea-ice extent, control the overall structure and function of the Barents Sea ecosystem, a productive shelf-sea of the European Arctic which is experiencing a rapid retreat in sea ice extent.
My work is focussed upon the phytoplankton; the photosynethic producers that form the base of the ecosystem.
I construct empirical and semi-empirical algorithms, based on natural phytoplankton samples’ optical properties and sea-surface-reflectance computed in radiative transfer models, with the aim of using ocean-colour to distinguish different major taxonomic groups of phytoplankton in satellite images. Different taxonomic groups of phytoplankton have different broad relationships with the Barents Sea’s ecosystem and biogeochemical cycles, so the ability to monitor the taxonomic composition of the phytoplankton with remote-sensing will allow researchers to make more nuanced synoptic observations about the ecosystem’s state as it adjusts in response to anthropogenic global warming.
