- Sea Surface Temperature Radiometers: Provide accurate temperature readings of ocean surfaces.
- Scatterometers: Track wind patterns over the ocean surface.
By integrating these technologies, NASA creates a comprehensive picture of global ocean behavior, enabling scientists to predict weather patterns and assess climate change impacts.
Impact of Climate Change on Oceans
Climate change significantly affects the world's oceans, leading to rising sea levels, increased acidity, and altered marine habitats. NASA's research has been instrumental in documenting these changes, using satellite data to track long-term trends in ocean temperature and chemistry.
Key Findings
- Global sea levels have risen approximately 8-9 inches since 1880.
- Ocean acidity has increased by about 30% since the industrial revolution.
- Marine heatwaves are becoming more frequent and intense.
These findings underscore the urgent need for action to mitigate climate change and protect marine ecosystems.
Marine Ecosystems and Their Importance
Marine ecosystems are vital to the health of our planet, supporting biodiversity and providing essential resources for human survival. NASA's research highlights the interconnectedness of these ecosystems and the threats they face from human activity and climate change.
Through satellite imagery and remote sensing, NASA monitors coral reefs, kelp forests, and other critical habitats, providing data that informs conservation efforts worldwide.
