I’m a CENTA PhD student focused on researching high latitude (≥50°N and ≥40°S) dust emissions. My research will employ remote sensing, GIS, and fieldwork to analyse dust dynamics in these regions. Previously, I contributed to a European Space Agency/Future Earth funded project on high-latitude dust identifying dust through satellite observations. Additionally, I have a background in bedrock river erosion, which was the focus of both my undergraduate and master’s theses.
Arctic dust from above and below: Constraining the unseen contributions of northern high latitude dust sources
PGR Supervisors: Dr Matthew Baddock and Professor Joanna Bullard
This research focuses on dust emissions from high latitude regions (≥50°N and ≥40°S) and their impact on the environment. Dust from these areas account for 5% of global dust emission and play an important role in cryospheric, climatic, and biological processes at a range of scales. However, ground monitoring of high latitude dust emissions are limited, and satellite observations may underestimate emissions due to the size, timing or dispersal characteristics of dust. Furthermore, issues such as cloud cover may obscure dust emission. Field measurements, such as dust mass and vertical flux, will be collected and compared with satellite observations to identify gaps and improve monitoring accuracy. This research aims to understand how environmental factors influence dust emissions in high latitude regions, while addressing biases and errors in data sources to improve the accuracy of regional dust loading estimates.
