Net phytoplankton community biomass fell back from last week's high and total chlorophyll biomass remained elevated (ca 0.51x to 5.63 ug/L net, ca 1.08x to 94.57 ug/L total by in vivo fluorescence). Pseudo-nitzschia spp remained dominant, but declined in abundance compared to the prior sample (ca 0.79x to 581,870 cells/L, 85% seriata size class). Other diatom taxa were in low abundance, but increased in species richness. Dinoflagellates also remained rare but were led again by Gonyaulax spinifera and Boreadinium spp. Dinophysis spp remained rare.

Pseudo-nitzschia spp remained dominant, although continued their decline in abundance (ca 0.54x to 47,146 cells/ L, 72.6% seriata size class). Other diatom taxa were in low abundance. Dinoflagellates remained rare but increased in species number led again by Gonyaulax spinifera (857 cells/L). Dinophysis spp were rare. Phaeocystis increased in relative abundance.

Net phytoplankton community biomass continued on an upward trajectory (ca 1.19x to 7.28 ug/L net, ca 1.22x to 81.40 ug/L total by in vivo fluorescence) as the bay settled into a relaxation period. Water clarity remained low. Pseudo-nitzschia spp remained dominant, although their abundance fell back slightly, delicatissima size class morphotypes increased in relative abundance (ca 0.78x to 456,544 cells/ L, 71.2% seriata size class). Other diatom taxa were in low abundance. Dinoflagellates remained rare and were led again by Gonyaulax spinifera (1,222 cells/L), Boreadinium (ca 815 cells/L). No Dinophysis spp were observed.

Net phytoplankton community biomass nearly doubled compared to last sample ( ca 1.82x to 6.13 ug/L net, ca 2.41x to 66.59 ug/L total by in vivo fluorescence) with a corresponding decrease in water clarity. Pseudo-nitzschia spp tripled in abundance (ca 3.33x to 587,276 cells/ L, 87.8% seriata size class) and remained dominant. Chains were 6-10 cells in length and well pigmented. Other species were in low abundance. Dinoflagellates increased in abundance but remained rare due to Pseudo-nitzschia abundance and were led by Gonyaulax spinifera (2,649 cells/L), Boreadinium (ca 1158 cells/L) and Scrippsiella (883 cells/L). Dinophysis spp were only observed in live fields(<< 440 cells/L).

Greeting from the Monterey Bay Wind Tunnel! Our sampler was again thankful that this AM was near picture perfect and calm at the wharf. On-shore winds have been consistently strengthening in the afternoons and MBARI's M1 mooring at the outer edge of the bay reports current nitrate concentrations near 20 uM (doubled from mid March levels).
Net phytoplankton community biomass was higher this week ( ca 2.15x to 4.06 ug/L net), total chlorophyll biomass was up slightly ( ca 1.17x to 26.68 ug/L total by in vivo fluorescence). Pseudo-nitzschia spp remained dominant and increased in abundance and diversity (ca 1.58x to 226,302 cells / L, 81.3% seriata size class) with long chains becoming more common (>10 cell max length). P multiseries/pungens like cells were common. Other species were in low abundance. Dinoflagellates were lead by Boreadinium (227 cells / L). Dinophysis spp were not observed.

Strong onshore winds (WNW, 55mph peak!) started off the week and stirred up the bay. Our intrepid sampler was thankful that today was near picture perfect and calm. None the less, net phytoplankton community biomass was again lower this week ( ca 0.80x to 1.89 ug/L net) while total chlorophyll biomass increased ( ca 1.65x to 22.83 ug/L total by in vivo fluorescence) likely due to re-suspended detritus. Pseudo-nitzschia spp remained dominant (ca 1.41x to 142,886 cells / L, 91.6% seriata size class), but showed impacts of increased water turbulence, occurring largely as single or 2 cell chains (6 cell max length). Dinophysis spp returned, but were rare.

Net phytoplankton community biomass fell back this week ( ca 0.49x to 2.35 ug/L net; ca 0.47x to 13.82 ug/L total by in vivo fluorescence). Pseudo-nitzschia spp were still dominant but at lower abundance than last week (ca 0.31x to 101,388 cells / L, 93.9% seriata size class). Chaetocerus convolutus was the next most abundant species. Dinoflagellates decreased in abundance and diversity. No Dinophysis were observed.

A beautiful morning at the wharf. Olive green waters offered a sharp contrast to the relative clear waters sampled last week on the San Pedro shelf. Our local community continued on its upward trend with net phytoplankton community biomass double the level reported for the 3/13 sample ( ca 2.58x to 4.75 ug/L net; ca 2.32x to 28.96 ug/L total by in vivo fluorescence). This increase was associated with a Pseudo-nitzschia spp bloom (ca 6.42x to 331,583 cells / L, 87.7% seriata size class) which dominated the community. Other diatoms were present to rare in abundance. Dinoflagellates increased in abundance and diversity led by Noctuluca (>>1000 cells / L). Dinophysis spp (922 cells / L) were present in the background.

Last week ended with the return of strong onshore winds in the afternoon and clear weather. Net phytoplankton community biomass was substantially higher in the sample this week ( ca 5.15x to 1.84 ug/L net; ca 1.61x to 12.48 ug/L total by in vivo fluorescence). Diatoms increased their numerical dominance and increased in species richness, led by Pseudo-nitzschia spp (ca 4.92x to 51,658 cells / L, 89.2% seriata size class). Dinoflagellates were generally rare.

Quiet day at the wharf after overnight rains. Net phytoplankton community biomass was lower in the sample this week ( ca 0.15x to 0.36 ug/L net; ca 0.58x to 7.77 ug/L total by in vivo fluorescence). In spite of the biomass decline, diatoms retained their numerical dominance, still led by Pseudo-nitzschia spp which decreased in abundance (ca 0.16x to 10,503 cells / L, 90% seriata size class). Dinoflagellates were rare. Detritus dominated the sample.
