Remote Sensing Techniques for Ocean Monitoring and Marine Life Tracking

The video discusses how NOAA uses remote sensing to gather data about the ocean, track changes in coastlines, and monitor animal movements. Remote sensing involves using sensors on satellites or aircraft to collect information from a distance. These sensors can be passive, like those measuring infrared radiation, or active, like LIDAR systems. NOAA uses these technologies to map coastlines, track sea surface temperatures, and monitor wildlife. The video encourages viewers to think of new ways to use remote sensing and highlights NOAA's role in informing the public about environmental changes.

What are some of the challenges in monitoring the ocean mentioned in the video?

• Tracking coastline changes over time

• Measuring ocean temperature at a single point

• Monitoring animal movements in the ocean
