Cue Plankton: Ocean Timekeepers

Cue Plankton: Ocean Timekeepers is a lesson developed for high school students to explore a particular species of zooplankton, a copepod, known as Pleuromamma xiphias. The lesson looks at the process of diel vertical migration (DVM) and an organism’s ability to demonstrate predictable, daily cycles of fluctuation, known as circadian rhythms. The purpose of the lesson is to understand the structure of the water column at one of BIOS’s spatial stations, Hydrostation ‘S’, in the Sargasso Sea. The lesson explores circadian rhythms and timing of fecal pellet production by P. xiphas. Students will utilize the freeware ‘Image J’ to analyze photographs taken from a research cruise at BIOS in March 2019.

Check out the lesson plan, worksheetCTD Data, and fecal pellet stack data. Educational resources were supported by NSF grant #1829318.
