- Scientists have developed ‘GoFlow’, a new technology using artificial intelligence to monitor ocean surface currents in unprecedented detail.
- ‘GoFlow’ converts seasonal satellite images into high-resolution maps of ocean currents, providing updated maps every hour.
- It is expected to aid weather forecasting, tracking oil spills, and managing marine pollution.
April 21, Kathmandu. Scientists have developed a groundbreaking technology that uses artificial intelligence to track ocean surface currents with unmatched detail.
Named ‘GoFlow,’ this technology transforms images captured by seasonal satellites into high-quality maps illustrating ocean current velocities and directions.
Published in the journal Nature Geoscience, this discovery opens new avenues for understanding Earth’s climate and marine ecosystems.
Developed by Luke Letten and his team at the Scripps Institution of Oceanography, the technology employs deep learning to analyze thermal satellite imagery, detecting subtle changes in temperature patterns to identify the speed and direction of water flow.
Previously, it was considered impossible to observe such small-scale and rapid-moving waves directly.
Why is this discovery important?
Ocean currents play a crucial role worldwide by balancing temperatures, transporting carbon dioxide from the atmosphere to the deep ocean, and delivering nutrients to marine life.
Earlier satellites only observed the same location once every ten days, missing waves that form and dissipate within hours. ‘GoFlow’ provides fresh hourly maps, making it easier to understand complex processes such as vertical mixing in oceans.
New capabilities from existing satellites
A major advantage of this technology is that it doesn’t require launching new space instruments.
Tests conducted in the North Atlantic since 2023 have demonstrated that the technology’s accuracy matches measurements taken from ships. Scientists have specifically used it to study complex currents like the Gulf Stream.
Although cloud cover can interfere with satellite imaging, researchers plan to integrate data from additional satellites to enable global coverage.
This innovation is expected to significantly improve weather forecasting, oil spill tracking, and marine debris management. Furthermore, it allows empirical testing of decades-old theories on how oceans absorb heat and carbon based on real data.
