Coastal fog gave way to clear onshore conditions during this morning's sampling at the Monterey Wharf.  Net chlorophyll was lower in this week's samples, while total chlorophyll biomass increased (Net Fraction: 0.79X to 2.68 ug/L chl; Total: 02.2X to 37.6 ug/L by in vivo fluorescence).  Net biomass was dominated by Pseudo-nitzschia seriata size class along with an assortment of chain forming diatoms. Dinoflagellates were rare but active in the background. Pseudo-nitzschia spp. decreased in overall abundance (2.17X to  152,145 cells/L, 96% seriata size class).

Although a thick marine layer and coastal fog made for a bleak morning sampling at the Monterey Wharf, the dark brown color of the first net haul brighten our intrepid samplers mood with the realization of a strong phytoplankton bloom at this locale. Net and total chlorophyll were dramatically higher in this weeks samples (Net Fraction: 8.6X to 14 ug/L chl; Total: 7.6X to 95.5 ug/L by in vivo fluorescence).  Net biomass was dominated by an assortment of diatoms with dinoflagellates active in the background.

Net and total chlorophyll were higher in this weeks samples (Net Fraction: 3.38X to 1.63 ug/L chl; Total: 2.33X to 12.50 ug/L by in vivo fluorescence).  Net biomass was dominated by an assortment of diatoms with dinoflagellates active in the background.

Phytoplankton biomass about the same as last week, net tow still mostly diatoms.  There was a shift in the assemblage, today’s was co-dominated by Skeletonema and Chaetoceros.  Pseudo-nitzschia decreased this week, but both delicatissima and seriata size classes were observed.  There was also an 8-cell chain of Alexandrium zooming around the petri dish this am.

Clear skies and sunshine warmed the bay during this morning's sampling at the Monterey Wharf.  Net chlorophyll was lower in this week's samples (Net Fraction: 0.48X to 1.09 ug/L chl; Total: 0.69X to 13.12 ug/L by in vivo fluorescence).  Living biomass was dominated by a diverse community of diatoms, although many exhibited condensed chloroplasts. Pseudo-nitzschia spp. was common in the sample but at slightly lower abundance that the previous week and with delicatissima size class increasing in relative abundance (0.95X to 43,089 cells/L, 80% seriata size class).   Dinoflagellates were present and active.

A beautiful morning at MWII indicating that Spring is just around the corner. Net chlorophyll increased this week (Net Fraction: 27X to 1.67 ug/L chl; Total: 1.84X to 12.21 ug/L by in vivo fluorescence) and was associated with a diatom bloom. The net sample was dominated by Chaetoceros spp. Pseudo-nitzschia were rare (<1000 cells/L, 50% seriata size class). Dinoflagellates were active but at low abundance.

Early morning rain left the wharf damp and storm clouds lingered over the bay, giving way to late afternoon heavy rains and high winds. Net chlorophyll continued to decline, although total chlorophyll increased likely associated with heavy detrital and sediment loads stirred up in this stormy weather (Net Fraction: 0.3X to 0.12 ug/L chl; Total: 1.5X to 7.65 ug/L by in vivo fluorescence). Pseudo-nitzschia spp. were rare with only 2 delicatissima class cells observed in the live sample.

The morning offered a brief respite from heavy rains and associated atmospheric river impacting our region for the past several days. Chlorophyll declined over the past week (Net Fraction: 0.44X to 0.40 ug/L ; Total: 0.88X to 4.99 ug/L by in vivo fluorescence). Pseudo-nitzschia spp. abundance declined sharply (0.02X to <1,000 cells/L, 100% seriata size class). A diverse assortment of other diatoms and dinoflagellates were present with dinoflagellates being dominant overall. Alexandrium catenella-like cells were observed in 3-4 cell chains.

Dark clouds continued to occlude the sky over the Monterey Wharf this morning as the first wave of several rain fronts passed through overnight (5+ inches!). The first sampling of the new year revealed a moderate amount of chlorophyll at this locale (Net Fraction: 0.9 ug/L chl ; Total: 5.68 ug/L by in vivo fluorescence). Pseudo-nitzschia spp. were surprisingly abundant in todays samples (41,862 cells/L, 99% seriata size class), an early appearance for this diatom. A diverse assortment of other diatoms and dinoflagellates were present with diatoms being dominant overall. Alexandrium catenella-like cells were observed in 3-4 cell chains.
