Exploring the world's oceans through satellite technology
We study the world's oceans, which hold more than 97% of Earth's water and possess a heat capacity far greater than that of the atmosphere. They function like a massive capacitor, regulating weather and climate across both short- and long-term scales. We explore its dynamics, which govern the motion, transport, and distribution of mass, heat, and tracers across different parts of the oceans and their neighboring systems to maintain the Earth system's equilibrium. We leverage space technology for its unmatched global reach in monitoring changes across the oceans.
The OSTST (Ocean Surface Topography Science Team) meeting is an annual event where scientists discuss the latest advancements in satellite altimetry and ocean surface topography. The Sentinel-6B satellite is part of the Copernicus program and plays a crucial role in monitoring sea level rise and climate change.
Our latest study published in Nature reveals the potentials of the Surface Water and Ocean Topography mission in studying ocean processes at submesoscales (<100 km).
