Profile

PhD student in environmental science in the Climatic Research Unit (CRU) at the University of East Anglia. My primary research interests involve studying the interactions between bio-physical feedbacks and ocean physics and how this influences climate variability and change. I also conduct research into the ocean-desert processes and its linkage with Pacific Decadal Oscillation, with a particular focus on North Pacific ocean desert. I have experience in numerical modelling, Neural Networks, satellite data analysis and onboard phytoplankton incubation experiment.

PhD title: Ocean surface radiant heating by phytoplankton: processes and feedbacks driven by climate variability and change

Previous studies have shown that marine ecosystem plays an important role in regulating climate. Marine phytoplankton strongly influences biogeochemical processes in the ocean and contributes approximately half of the global primary production. However, one of the direct and important impacts of phytoplankton on climate systems has received relatively little attention, namely the bio-physical feedbacks by which chlorophyll and the related pigments in phytoplankton absorb solar radiation and then change sea surface temperature. However, our understanding of this mechanism is mainly limited to specific areas e.g. Arctic, and such bio-physical impact is not considered in some earth system and climate models, nor is its impact on the climate quantified. This project will aim to use UK Earth system model (UKESM) coupled with biogeochemical model to investigate the impact of Chl-induced heating on sea surface temperature and thus ocean dynamical processes, and further understand how climate variability and change impact Chl-induced heating process and its feedback to climate.
