Exercise 1 (Excel): Explore the latitudinal distribution of ecologically distinct taxa.
1.1. Calculate the relative abundance (%) of each taxa. Explore the latitudinal distribution of cells/L and %s of the 4 taxa. Describe the obtained plots.
1.2. Explore the following relationships (use cells/L) and describe the obtained plots:
- E. huxleyi and Chl-Fluorescence vs. D. tubifera and Chl-Fluor.
- Shannon-Weaver Diversity Index (H’ Exp) vs. Chl-Fluor.
- E. huxleyi, D. tubifera and F. profunda vs. Depth
- E. huxleyi, D. tubifera and Holococcolithophores vs. Temperature
