  1. Finding Fish Using Satellites Pete Arvedson California Science Conference October 25, 2013 Hosted by Satellite Educators Association Lesson plan development supported by a grant from NOAA-CREST West

  2. A Little History… • “Fishing via Satellite” lesson plan by Karen Roshong ~ 1991 • Published in Lessons from the Sky - 1995

  3. Session Objectives • Explain fish behavior related to changes in water temperature • Access satellite-based sea surface temperature data • Visualize, Analyze, Interpret data • Hypothesize fish locations based on analysis

  4. Ocean Fish Behavior • Changes in marine ecosystems have patterns… • Including temperature variations • Seasonal • Diurnal • Ocean fish metabolism is environmently dependent • Fish respond to changes in… • Oxygen availability • Food supply • Temperature

  5. Satellites • > 24,500 objects are in Earth orbit • ~ 560 operational satellites • Many are Earth looking • Weather satellites • Geostationary (GOES) • Polar orbiting • POES • JPSS

  18. 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

  19. 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)
