Dimitra Denaxa is a physical oceanographer and research assistant at the Institute of Oceanography of the Hellenic Centre for Marine Research (HCMR), where she has been working since 2015. Her PhD focused on extreme warming and marine heatwaves in the Mediterranean Sea, investigating theirspatio-temporal characteristics, physical drivers, and underlying ocean–atmosphere interactions. She holds an MSc in Environmental Physics and a BSc in Physics with specialization in Environmental Physics and Meteorology from the National and Kapodistrian University of Athens. Since 2016, she has been a member of the POSEIDON system research team at the HCMR and has been actively involved in Copernicus Marine research projects (Copernicus Marine Environment Monitoring Service – Mediterranean Monitoring and Forecasting Centre), where she currently contributes as Ocean State Report and Ocean Monitoring Indicators Expert Deputy, and as Product Manager Deputy for the Med-WAV component. Her research focuses on ocean warming and marine heatwaves, climate variability, air–sea interaction processes and ocean waves, combining statistical analysis, numerical modelling, and observational datasets.
