Routine monitoring, Monterey Municipal Wharf II

Routine monitoring at the Monterey Wharf

HABMAP

Every Wednesday, a member of EBL travels down to the Monterey Commercial Wharf- MWII and collects water samples from phytoplankton net tows and a Van Doren. These water samples are taken back to the lab for analyses which include nutrients, chl-a, RAI, and cell counts. For more information please visit https://habs.sccoos.org/monterey-wharf.

Weekly Updates 

Below are some images of phytoplankton we have observed during our weekly RAIs. Descriptions for each sampled week are listed below the gallery.
