Of sea-ice models and phytoplankton.
In this episode, Charlotte walks us through her research on how differences in sea ice models affect the biological processes in an Arctic ocean model. She breaks down how sea ice influences phytoplankton dynamics in the real world and in numerical model simulations. If you're navigating your own thesis project or feeling the pressure of an approaching deadline, the episode closes with a dose of support and motivation to help you keep going!
Update: As the planet keeps turning, NOAA’s latest Arctic Report Card (December 2025) revealed that March 2025 marked the lowest annual Arctic maximum sea ice extent in the 47 years of available satellite record.
