| Abstract: |
| |
| Phytoplankton data through July 2007. It's in a crosstab format (station and date down the side, with genus names across the top). It's a fairly hefty dataset (about 5000 sampling events). Genera that had less than 10 records for the entire dataset were eliminated. ~ 90 genera total. There are some samples where no phytoplankton were seen; in these cases you will see zeros across all the rows. The values given are organisms per milliliter. Station and genus metadata are included.
A quick note about some of the taxa: we see a lot of benthic taxa in our samples because they become entrained in the water column. Practically all our pennate diatoms are benthic. The taxon "unidentified flagellate" is any flagellate thing we see that can't be identified (I think this is usually because they are not algae, but heterotrophic protists). All of our algal flagellates (i.e. cryptomonads, flagellated green algae) are usually identified, unless they're too damaged. I think this is rare, though; I think the majority of our algal flagellates can be identified, so very few would ever be called "unidentified flagellate" As for the class and common names, I've gone off the most recent stuff that I have. I don't particularly like calling a group of algae "yellow-brown" or "yellow-green" for 2 reasons: 1) frankly, it doesn't tell you much about the group, and 2) many taxa in different classes share pigments, and will have a similar color. Something like "haptophyte" gives you a much better idea of where the alga belongs taxonomically. Lastly, I've used the term "cyanobacteria" instead of "blue-green algae" for a common name for the class Cyanophyceae. I prefer the term "cyanobacteria" because they are the only group of algae that are prokaryotic. |
