This presentation by Pete Arvedson at the California Science Conference on October 25, 2013, explores how satellite technology is leveraged to find fish by analyzing sea surface temperature data. Supported by NOAA-CREST, it covers the behavior of fish in relation to environmental changes and the vital role of satellites in gathering essential oceanographic data. The session includes objectives, lesson plans, extension activities, and connections to California Science Content Standards, emphasizing the importance of satellite data in marine research and education.

Extension Activities • Access ocean topography image, same data – compare • Use same technique to predict different fish caught from different port • Devise a plan to “ground-truth” the satellite-based SST • Find & process a MODIS image for SST • Devise a plan for determining in which season coastal eddy currents and upwelling are most common • Explore linear relationship between SST and pixel brightness value in Level 3 data
CA Science Content Standards • Grade 6: Ecology – • Organisms in ecosystems exchange energy and nutrients among themselves and with the environment. (e) • Grade 6: Investigation and Experimentation – • Scientific progress is made by asking meaningful questions and conduction careful investigations. (b, c) • Grades 9-12: Biology/Life Science - • Stability in an ecosystem is a balance between competing effects. (a, b, c) • Grades 9-12: Investigations and Experimentation – • Scientific progress is made by asking meaningful questions and conducting careful investigations. (a, i)
