While Noctiluca were still present, their surface expression was not. A bloom of Chaetocerus socialis colonies was apparent in the sample bottles. Net chlorophyll biomass, increased relative to last week's sample (ca 6X to 0.66 ug /L; total chlorophyll 5.08 ug/ L by in vivo fluorescence). Diatoms returned to dominance. Although Pseudo-nitzschia spp. continued to decrease in abundance, ( ca 0.63X to 1,655 cells / L; 100% seriata size class), well pigmented, ca 10 cell chains were routinely observed. Water temperature decreased by 2 oC over last week.

Surface filaments of orange were shoreward of the sampling location and the pier fishermen recognized this as a small red tide. Noctiluca were in abundance in todays sample (1,538 cells / L) and quickly resumed their surface expression in the sample bottles. In spite of this bloom, net chlorophyll biomass, declined sharply relative to last week's sample (ca 0.03X to 0.11 ug /L; total chlorophyll 7.75 ug/ L by in vivo fluorescence). Diatoms finally lost their dominance and many unpigmented frustules were observed. Pseudo-nitzschia spp. continued to decrease in abundance, ( ca 0.34X to 2,637 cells / L; 42% seriata size class). Water temperature increased by 1.5 oC over last week.

The upward trend in net chlorophyll biomass continues, doubling relative to last week's sample (ca 2.7X to 3.36 ug /L; total chlorophyll 8.28 ug/ L by in vivo fluorescence). Diatoms were dominant lead by Skeletonema spp. Pseudo-nitzschia spp. decreased in abundance, species representation changed with a shift towards delicatissima size class ( ca 67X to 7,710 cells / L; 47% seriata size class). Dinoflagellates decreased in abundance and were led by Ceratium lineatum and Gyrodinium spp. Water temperature was again lower.

Water at this site remains sediment laden. Net chlorophyll biomass increased from last sample (ca 6.6 X to 1.53 ug /L; total chlorophyll 22.70 ug/ L by in vivo fluorescence) although the samples were dominated by sediment fines and detritus. Diatoms held the upper hand in the sparse phytoplankton community. Pseudo-nitzschia spp. was rare in this sample (< 200 cells / L). Dinoflagellate diversity decreased and this group was led by Ceratium teres.

Net chlorophyll biomass decreased relative to last week's sample (ca 0.5X to 0.76 ug /L; total chlorophyll 14.07 ug/ L by in vivo fluorescence) and water clarity increased. Species richness of both diatoms and dinoflagellates increased, with diatoms maintaining numerical abundance in the sparse phytoplankton community. Pseudo-nitzschia spp. was present (1,715 cells / L; 75% seriata size class). Dinoflagellates were led by Ceratium furca at a similar abundance. A mackerel run had sea lions and wharf fisherman busy with fresh catch.

While the rains have passed, high flows from the Salinas, Pajaro rivers and other watersheds around the bay contributed to large sediment (and ??) plumes impacting the bay. In spite of several days of warm, sunny weather, net chlorophyll biomass declined from last sample (ca 0.2X to 0.23 ug /L; total chlorophyll 8.32 ug/ L by in vivo fluorescence) with the samples dominated by sediment fines and detritus. The sparse phytoplankton community was a relatively even mix by diatoms and dinoflagellates. Pseudo-nitzschia spp. abundance continued its declined (ca 0.2X to 1,293 cells / L). Dinoflagellates were led by Ceratium teres. Multiple Dinophysis spp along with Alexandrium spp (3 cell chain) were observed. Water temperature increased by 3 oC over the last week.

Rainy weather has impacted the Monterey Bay region since last Friday. Net chlorophyll biomass has declined from last sample (ca 0.2X to 0.41 ug /L; total chlorophyll 12.94 ug/ L by in vivo fluorescence). Remaining community is a relatively even representation by diatoms and dinoflagellates. Pseudo-nitzschia spp. abundance continued its declined (ca 0.23X to 6,246 cells / L). Dinoflagellates increased in relative abundance and diversity, led by Prorocentrum micans (806 cells / L). Multiple Dinophysis spp were observed (ca 300 cells / L total). Turbidity and sediment load increased and surface sediment plumes were visible.

Net chlorophyll biomass continued on an upward trend (ca. 3X to 2.3 ug /L; total chlorophyll 16.82 ug/ L by in vivo fluorescence). This biomass trend is largely attributable to Pseudo-nitzschia spp which dominated the assemblage in this sample (98,965 cells / L, a 3.9X increase, all seriata size class). Cells had robust chloroplasts and chains over 30 cells (80+ member chain observed) were common in live samples. Dinoflagellates decreased in abundance. No Dinophysis spp were observed.

Sampling followed on the heels of an overnight/early morning storm set. The net phytoplankton community continues to bloom, with diatoms dominating. Net chlorophyll biomass increased again (ca. 2X to 4.43 ug /L; total chlorophyll 24.05 ug/ L by in vivo fluorescence). Skeletonema spp. along with a mix of nine Chaetocerus species comprise the bulk of the net sample. Pseudo-nitzschia spp. continue to increase in abundance (ca 2X to 14,272 cells / L; 97% seriata size class), chains over 20 cells were observed in live samples. Dinoflagellate abundance remained low, with Gyrodinium, Noctiluca and Polykrikos leading this group.
