Clear skies, calm winds and cold air greeted our intrepid sampler this morning at MWII. Net chlorophyll continues to yo-yo, declining in this sample from the prior week's level (Net Fraction: 0.3X to 0.34 ug/L chl ; Total: 0.99X to 8.24 ug/L by in vivo fluorescence). Pseudo-nitzschia spp. continued to increase in abundance and morphological diversity (1.7X to 7,427 cells/L 49% seriata class). Akashiwo sanguinae were finally rare in the samples. Overall, phytoplankton abundance was low but diverse, with a shared representation of diatoms and dinoflagellates. Water temperature declined by ca 2oC over the past week.

Hazy fog lingered offshore, but clear sunshine prevailed over the Monterey Wharf this morning. The bay was impacted by another set of large (>15') swells from N Pacific storms. Net chlorophyll decreased from the prior week's level (Net Fraction: 0.1X to 0.48 ug/L chl ; Total: 0.2X to 6.08 ug/L by in vivo fluorescence). Overall, biomass was low and the net samples largely dominated by sand and detritus. A few Pseudo-nitzschia spp were observed in both fixed and live samples (1,500 cells/L 100% seriata class, few 5-6 cell chains). Other diatoms were equally rare. Akashiwo sanguinae was common but no longer dominant. Other dinoflagellates were active in the background.

A cold but clear morning at the Monterey Wharf. Water temperature increased by ca. 1 oC over the past week, which encompassed several rain events. Net chlorophyll decreased from the prior week's level (Net Fraction: 0.7X to 4.5 ug/L chl ; Total: 0.7X to 26.9 ug/L by in vivo fluorescence). A few Pseudo-nitzschia spp were observed only in the live samples (<100 cells/L 50% seriata class). Other diatoms were equally rare. The sample continued to be dominated by the dinoflagellate Akashiwo sanguinae but its abundance continued to decline (0.59X to 19,816 cells/L) with ca. 75% of cells in various stages of lysis. Other dinoflagellates were rare.

A cloudy morning greeted our intrepid sampler. Water temperature increased by ca. 1oC over the past week. Net tows were again thick and red-brown. Waters were dark brown under the wharf at the Monterey Bay Abalone Co and surf break was also discolored. Net chlorophyll increased from the prior week's level (Net Fraction: 9.7X to 27 ug/L chl ; Total: 7.23X to 145 ug/L by in vivo fluorescence). Pseudo-nitzschia spp were rare. The sample continued to be dominated by the dinoflagellate Akashiwo sanguinae which increased in abundance (4.4X to 108,460 cells/L) however >50% of identifiable cells were lysed or degrading indicating a shift in physiological state of this population. A mixed community of other dinoflagellates and diatoms were active in the background.

Clear skies, sunshine and cooler temperatures prevailed at the Monterey Wharf for the day's sampling. Net tows were again thick and red-brown. The ongoing red tide had a more patchy surface distribution at the time of sampling. Net chlorophyll decreased from the prior week's level (Net Fraction: 0.55X to 2.79 ug/L chl ; Total: 0.1X to 20.06 ug/L by in vivo fluorescence). Pseudo-nitzschia spp were rare and only an aging 2-cell chain was observed in live samples. The sample continued to be dominated by the dinoflagellate Akashiwo sanguinae (0.003X to 24,600 cells/L) but the presence of many lysed cells and ejectosome like structures point to a decline phase of this bloom. A mixed community of other dinoflagellates and diatoms were active in the background.

Offshore fog and cooler temperatures returned to the bay, following several days of record breaking heat (32oC+!). Surface water temperature was similar to last week's observation. Net tows were thick to clogging and red-brown. Net chlorophyll increased from the prior week's level (Net Fraction: 6X to 5.0 ug/L chl ; Total: 10.6X to 193 ug/L by in vivo fluorescence). Pseudo-nitzschia spp were not observed. A lone Chaetoceros spp chain represented the diatom community. The sample was dominated by a near mono-culture of the dinoflagellate Akashiwo sanguinae (ca 9,000,000 cells/L). This bloom appears to be impacting nearshore waters around the bay, and thick foam patches overlying red-brown waters were observed along the Moss Landing beach Thurs AM.

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).

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).
