About

Letizia Tedesco is a leading biogeochemical oceanographer whose research centers on polar marine ecosystems, sea-ice biogeochemistry, and the impacts of climate change on high-latitude oceans. Her work illuminates how shifting sea-ice dynamics and ocean warming alter nutrient cycles, primary production, and carbon fluxes in the Arctic and Southern Oceans. A key contribution is her synthesis of polar ocean–atmosphere interactions, exemplified in her highly cited 2023 paper “Polar oceans and sea ice in a changing climate,” which has already garnered 36 citations and underscores the urgency of understanding these rapidly transforming systems. Tedesco’s research integrates field observations, satellite data, and numerical modeling to predict how polar ecosystems will respond to ongoing environmental change. Her achievements include advancing the Surface Ocean–Lower Atmosphere Study (SOLAS) framework, highlighting the critical role of sea ice in global biogeochemical cycles. With a growing citation record and a focus on one of Earth’s most vulnerable regions, Tedesco’s work is essential for informing climate policy and conservation strategies in polar waters.
