Minisymposium Presentation
Understanding the Impact of Ocean Changes on Marine Ecosystems

Presenter
Hindumathi Palanisamy, an oceanographer specialized in sea level science is a Scientific Officer for World Climate Research Programme in the World Meteorological Organization (WMO). In this role, she serves as the Secretariat focal point for three of WCRP’s core activities focusing on ocean, atmosphere and land Earth system components – CLIVAR, APARC and GEWEX projects. Additionally, she also coordinates the Global Precipitation Experiment (GPEX) and Research on Climate Intervention Lighthouse Activities of WCRP. She also serves as the WCRP focal points within WMO for activities related to hydrology and ocean. Hindumathi has a PhD in space oceanography from the University of Toulouse and French Space Agency in France. Prior to joining WCRP Secretariat, Hindumathi was a senior research scientist at the Centre for Climate Research Singapore where she focussed on developing regional sea level research expertise in the Southeast Asian region. Earlier to that, she worked for the European Space Agency’s Climate Change Initiative- Sea Level Budget Closure project in Toulouse, France.
Description
The ocean is a fundamental driver of Earth’s climate, yet climate change and human activities are altering its physical, chemical, and biological processes. Rising sea levels, marine heatwaves, ocean acidification, and biodiversity loss pose significant threats to marine ecosystems and the communities that depend on them. These challenges are not uniform—coastal regions, small island nations, and marginalized communities, including women who play key roles in fisheries, ocean governance, and marine research, are often the most affected. Tackling these interconnected issues requires breaking silos across disciplines, geographies, and governance structures. Oceanography, climate science, and socio-economic studies must work in tandem, leveraging high-performance computing (HPC) to integrate climate models, satellite data, and regional ocean observations. Women scientists and policymakers are at the forefront of this collaborative effort, advancing scientific innovation, data-driven decision-making, and inclusive marine resource management. Their contributions help bridge research and policy, ensuring that diverse perspectives shape sustainable ocean governance. Global initiatives like the UN High Seas Treaty and Sustainable Development Goals (SDGs) highlight the importance of interdisciplinary cooperation. By fostering integrated, cross-sectoral action, we can strengthen ocean resilience and safeguard marine ecosystems for future generations.
