Introduction
I am interested in how changes in the cryosphere, particularly Antarctic ice shelves, lead to changes in the biology of the polar oceans. Using numerical models and comparing my results with data from satellites and research cruises, I am trying to understand what lies behind the massive phytoplankton bloom in the Amundsen Sea, West Antarctica.

Dotson Ice Shelf (DIS) in West Antarctica is undergoing rapid basal melting driven by intrusions of warm, saline Circumpolar Deep Water (CDW) onto the continental shelf. Meltwater from DIS is thought to influence biology in the adjacent Amundsen Sea Polynya (ASP), which exhibits the highest net primary productivity (NPP) per unit area of any coasta...
The Amundsen Sea Polynya (ASP) has the highest Net Primary Productivity (NPP) per unit area of any of the coastal polynyas around Antarctica (Arrigo et al. 2003). Previous observations and modelling suggest that nearby Dotson Ice Shelf (DIS) plays an important role in driving this high NPP by relieving iron limitation in the ASP (St Laurent et al....
