The peninsula finally got some rain after a very dry fall. Net phytoplankton community biomass was sharply lower this week (Net Fraction: ca 0.12x to 0.39 ug/L chl; Total: ca 0.07x to 2.69 ug/L by in vivo fluorescence). Although at low abundance diatoms remained dominant, led by a mix of Chaetocerus spp.
(6,752 cells/L). Pseudo-nitzschia spp declined in abundance (0.01x to 1,206 cells/L, all seriata size class) Dinoflagellates also declined in abundance, led by Cochlodinium spp (ca 0.78x to 1,206 cells/L) and Prorocentrum micans (ca. 0.06x to 241 cells/L). A mix of Dinophysis spp were in the background (<<241 cells/L total).

Net phytoplankton community biomass increased this week (Net Fraction: ca 2.8x to 3.18 ug/L chl; Total: ca 2.3x to 41.18 ug/L by in vivo fluorescence). Diatoms returned with a vengeance, increasing
in diversity and once again gaining dominance. Diatoms were led by a mix of Chaetocerus spp and Pseudo-nitzschia spp (132,045 cells/L, 98.5% seriata size class, >20 cell chains present).
Dinoflagellates remained present and diverse, led by Prorocentrum micans (ca 0.92x to 3,955 cells/L), Ceratium spp (ca 0.24x to 1,758 cells/L) and Cochlodinium spp (ca 0.21x to 1,538 cells/L).
Alexandrium spp. (4 cell chain obs.) and Dinophysis remained active in the background at <= 220 cells/L).

There are red patches off the Pajaro and almost nothing at the wharf…crazy. Net tow was mostly detritus/debris, with very few phytoplankton. If I didn’t know better, I’d say it was Jan (saw maybe 50 cells – so the RAI calls are skewed as 1 cell=Present). Cochlodinium (doublets) and Prorocentrum made up most of the phytoplankton community.

We'll be shifting platforms for the next few weeks associated with ECOHAB field activities in Monterey Bay. This report constitutes observations from MLML's RV JH Martin positioned ca 100 m from the standard MWII shore station. Net phytoplankton community biomass remained elevated (Net Fraction: 3.39 ug/L chl; Total: ca 30 ug/L by in vivo fluorescence on CTD). A chlorophyll maximum centered around 12 m extended along the southern bay out through Pt Pinos. Pseudo-nitzschia spp remained dominant at MWII (total counts: 517,012 cells/L, 87.1% seriata size class). Other diatoms were rare. Dinoflagellates were led by
Protoperidinium spp. (857 cells/L ea.). No Dinophysis were observed.

Net phytoplankton community biomass increased dramatically over last week's low (Net Fraction: ca 40.7x to 8.14 ug/L, Total: ca 8.63x to 38.41 ug/L total by in vivo fluorescence). Pseudo-nitzschia spp led the biomass resurgence (total counts: 131.4x to 532,403 cells/L, 76.6% seriata size class). Other diatoms were rare. Dinoflagellates decreased in abundance, but increased in species richness, still being led by a complex of Ceratium spp. and Protoperidinium spp. (472 cells/L each. No Dinophysis were observed. Water temperature declined by ca 1oC.
