Sustained Ocean Observing for Extremes, Tipping Points and Climate: Emerging Opportunities with New Remote Sensing Instruments and Platforms
Session ID#: 257774
Session Description:
Long-term, sustained ocean observations are essential for understanding and predicting key aspects of Earth’s climate system, including tipping points, long-term trends, and extreme weather and marine events. Ocean surface processes—such as currents, waves, and air-sea interactions—are critical to climate regulation, driving the exchange of heat, water, and carbon with the atmosphere, cryosphere, and land.
Continuous, high-resolution monitoring is needed to capture extreme events and detect early signs of abrupt change, such as shifts in ocean circulation or deep convection that could trigger tipping points. Yet this need is currently unmet—positioned between the high-frequency but spatially limited coverage of in situ systems and the wide-area but infrequent sampling provided by satellites.
This session explores opportunities to close this gap through advances in ocean remote sensing and novel airborne and spaceborne platforms. We welcome contributions from academia and industry on new sensors and the use of innovative platforms, including airships, drones, high-altitude platforms (HAPS), and next-generation satellites. The session will showcase the state of the art and identify strategies to develop scalable, low-carbon, and cost-effective systems—paving the way for a net-zero-compatible ocean observing network that can support forecasting needs, inform decision-making, and advance climate action.
