Cloud and fog cover returned to the MWII after a few brief appearances over the past week. Surface water temperature was similar to last week's observation, due to an overnight transition from warm water (>16oC) conditions that held over the preceeding 5 days. Net chlorophyll decreased from the prior week's level (Net Fraction: 0.38X to 0.81 ug/L chl ; Total: 0.8X to 18.2 ug/L by in vivo fluorescence). Pseudo-nitzschia spp all but disappeared from the community with only a few cells observed in live samples (<100 cells/L). Dinoflagellates were dominant due to a Akashiwo sanguinae bloom (17,500 cells/L).

A beautiful sunny morning at the Monterey Wharf. Surface water temperature was similar to last week's observation. Net chlorophyll also remained steady at the prior week's level (Net Fraction:1.0X to 2.10 ug/L chl ; Total: 0.98X to 23.03 ug/L by in vivo fluorescence). While Pseudo-nitzschia spp remained as a dominant member of the diatom community its abundance declined (0.5X to 58,967 cells/L 100% seriata size class, 10 cell chains common). Akashiwo sanguinae led the dinoflagellate community and has been discoloring the waters around the bay and Elkhorn Slough.

Surface water temperature declined by 2oC, reflecting pulses of strong upwelling favorable winds over the past week. This signal is also seen in our net chlorophyll which increased over the past week (Net Fraction: 1.98X to 0.61 ug/L chl ; Total: 1.86X to 10.17 ug/L by in vivo fluorescence). The phytoplankton community was again a mix of diatoms and dinoflagellates, but continued to be dominated by a mix of Chaetoceros species.

Another bright, clear and calm morning at the Monterey Commercial Wharf, following several days of gusting onshore winds (>10 m/s). Spring is truely here! Net chlorophyll was little changed compared to last week's sample (Net Fraction: 1.07X to 0.12 ug/L chl ; Total: 0.72X to 5.99 ug/L by in vivo fluorescence). The phytoplankton community was bursting with activity dominated by a diverse assemblage of dinoflagellates. Of note Dinophysis spp were common (2,143 cells/L) represent by at least three species.

Mostly sunny morning at the wharf with light cirrus clouds and gentle breeze. Chlorophyll is starting to creep upwards from winter lows (Net Fraction: 1.77X to 0.12 ug/L chl ; Total: 1.28X to 8.99 ug/L by in vivo fluorescence). Pseudo-nitzschia spp are gaining a foothold once again (1.56X to 6,001 cells/L, 75% delicatissima size class). A mixture of Chaetocerus species helped lead the diatoms to community dominance although there was also an increased species richness of dinoflagellates in the still sparse net community.

Net chlorophyll biomass was lower again this week (Net Fraction: 0.57X to 0.36 ug/L chl; Total: 0.41X to 3.22 ug/L by in vivo fluorescence). Diatoms retained community dominance, attributable to Pseudo-nitzschia spp. was continued its decline in abundance (0.77X to 40,941 cells/L, 97% seriata size class, chains 8 to 12 cells in length). Proboscia also provided diatom companionship (6,430 cell/L). Prorocentrum micans (0.70X to 2,787 cells/L) continued to lead the active and diverse dinoflagellate community.

Net chlorophyll biomass was relatively lower in this week's sample (Net Fraction: 0.31X to 0.59 ug/L chl; Total: 0.33X to 3.36 ug/L by in vivo fluorescence). This reflected a shift in the net community composition with a more even mix of diatoms and dinoflagellates. Pseudo-nitzschia spp. remained common but declined in abundance (0.41X to 21,649 cells/L, 89% seriata size class, chains less than 10 cells in length). Proboscia spp was the next most common diatom (3,248 cells/L). The dinoflagellate community was diverse and active, led by Prorocentrum micans (4,330 cells/L) and Dinophysis spp. (866 cells/L). The associated warming of the bay likely heralds an early start to our summer phytoplankton community.

Our ECOHAB surveys and MBARI's ESPs continue to document high levels of DA throughout the bay. Hapharzard collection of beached achovies documented acting feeding on Pseudo-nitzshia and near record high body burdens of DA, indicating movement of the toxin into the local food web.

Ah Spring is the time for (diatom) Love!
Net chlorophyll biomass decreased from the prior week (Net Fraction: 0.75X to 1.23 ug/L chl; Total: 0.306X to 5.20 ug/L by in vivo fluorescence). Diatoms retained their community dominance, although it reflected a more even distribution of Chaetocerus and Pseudo-nitzschia species. Pseudo-nitzschia abundance was lower in today's sample (0.33X to 52,945 cells/L, 97.2% seriata size class, chains 5-15 cells in length). Of note ca. 25% of the Pseudo-nitzschia chains had probable gametes and zygotes attached either on empty frustules or with condensed chloroplast-cytosol. These appeared to be restricted to P. australis like cells. pDA analyses are in progress but high toxin burden was reported this AM from the ESP deployed west of our sampling locale. Our Tuesday ECOHAB survey of the southbay was blown out, but we hope to get back on the water in the north bay on Thursday.

Net chlorophyll biomass fell back from last week's high (Net Fraction: 0.19X to 1.71 ug/L chl; Total: 0.52X to 22.42 ug/L by in vivo fluorescence). Phaeocystis was dominant in todays samples, contributing to a notable thickness to the water. Diatoms were more abundant than dinoflagellates. Pseudo-nitzschia spp led the diatoms, but decreased in abundance and visual 'quality' (0.73X to 148,320 cells/L, 93.6% seriata size class; 12 cell chains common, but ca 30% of chains with granular cytoplasm, likely senescent). As predicted last weeks pDA was at least 210 ng DA/L. Dinoflagellate diversity and abundance also declined with Gonyaulax spinifera and Protoperidinium spp leading the pack (ca 900 cells/L each). A 2 cell chain of Alexandrium pseudogonyaulax was observed again this week. Of particular note, we were able to observe an oomycete infected Pseudo-nitzschia release the fungal zoospores and have video of the post release behavior (available upon request).

In spite of gloomy weather, today's net tow came up golden brown. Net chlorophyll biomass reached a new high for the year (Net Fraction: 4.46X to 8.78 ug/L chl; Total: 3.30X to 43.30 ug/L by in vivo fluorescence). Net and whole water samples revealed a wonderfully diverse, mixed community of diatoms, dinoflagellates and Phaeocystis colonies. Diatoms remain the dominant group, with a bloom of several Psuedo-nitzschia species leading the pack (7.54X to 204,136 cells/L, 87.5% seriata size class, >15 cells/chain common) and likely to add to last weeks 12.7 ng/L pDA burden. Chaetoceros was also common led by C. socialis. Dinoflagellates were diverse and active, led by Scrippsiella spp and a large (50x100u) pink Gyrodinium spp (1,575 cells/L and 1,125 cells/L respectively. Well formed Phaeocystis colonies were also common and easily visible by eye in whole water samples.

Another beautiful day at the wharf. Net chlorophyll biomass increased relative to last week (Net Fraction: 7.38X to 0.50 ug/L chl; Total: 6.51X to 7.61 ug/L by in vivo fluorescence). Diatoms remained as dominant group, led by a mix of Chaetoceros species. Pseudo-nitzschia spp declined to background abundance (<200 cells/L) with only a single 4 cell chain (seriata size class) observed in the live sample. Dinoflagellates also increased in relative abundance in the community, led by Ceratium furca.

A rainy morning at the wharf. Net chlorophyll biomass increased sharply relative to last week (Net Fraction: 9.53X to 2.15 ug/L chl; Total: 1.48XX to 14.51 ug/L by in vivo fluorescence). This reflected a turnover of the phytoplankton community with diatoms gaining dominance for the first time in 2015. Diatoms were led by a mixed community of Chaetoceros spp. (7 types observed all common, many with nitzschoid hitchhikers). Pseudo-nitzschia spp also increased in abundance and diversity with the re-appearance of seriata morphotypes (ca. 20.67X to 26,579 cells/L, 49.2% seriata size class).
