Using chlorophyll a data from vertical profiling floats to understand and predict the distribution of Pacific albacore tuna.
Tuna are migratory apex predators, as well as an important commercial fish species. In this 5E lesson, students use ARGOs float data to predict relationships between an ocean parameter and the distribution of Pacific albacore tuna. Using a “battleship” type game based on data from vertical profile floats, students collect chlorophyll-a values and use the data to predict where a tagged tuna might be located on the gameboard.

Enrichment

  • Optional Extension #1: Create a line graph of the chl a data collected during the game.
  • Optional Extension #2: Students can explore the Argovis website to make their own Taylor on Tour gamecards.
  • Optional Extension #3: Interview a tuna fisher and ask them where they know tuna tend to be at various times of the year. More about tuna and tuna fishing
