Fowzia Ahmed smiles on the ice in her arctic gear

Fowzia Ahmed is a Ph.D. candidate in the Department of Environment and Geography, studying nutrient dynamics of sea-ice algae in the Arctic. In her recent study, she compiled a 30-year pan-Arctic dataset of sea-ice and sub-ice nutrients together with sea-ice chlorophyll a to examine regional, seasonal, and vertical patterns. The results show strong regional contrasts, with bottom-ice nutrients and algal biomass especially high in parts of the Canadian Arctic Archipelago, likely linked to tidal-driven mixing at the ice–ocean interface, and lowest in Arctic Ocean basins. Overall, the study improves understanding of pan-Arctic patterns in sea-ice nutrients. 

The study was published in the peer-reviewed journal Elementa: Science of the Anthropocene in December 2025.
