A spectacular morning for sampling at MWII as some warmer weather enters the area.  Water temperature declined again by ca. 1oC over the past week. Net and total chlorophyll were little changed from last sample (Net Fraction: 0.88X to 1.27 ug/L chl; Total: 1.02X to 26.88 ug/L chl by in vivo fluorescence). Diatoms were again the dominant group this week slight decline in the Pseudo-nitzschia bloom comprised mainly of smaller delicatissima size class cells (0.66X to 154,675 cells/L, 26.4% seriata, the later common in chains exceeding 20 cells). Other diatom taxa were present at best. Dinoflagellates decreased in abundance and diversity  led by Prorocentrum gracile (0.35X to 943 cells/L), Akashiwo sanguinae (0.15X to 472 cells/L) and Cochlodinium spp. (0.14X to 472 cells/L, singletons and chains of 4 cells were present). A single cell chain of Alexandrium (236 cells/L) was observed in fixed samples.

* Impressions *
A gloomy sky, cool temperature and calm seas tempered the intrepid sampler's expectations for todays haul from MWII. While waters were noticeably clearer due to a reduction in suspended sediments, net hauls exhibited a distinct yellow green hue. Water temperature declined by ca. 1oC over the past week. Net and total chlorophyll increased sharply from recent levels (Net Fraction: 4.44X to 1.45 ug/L chl; Total: 3.42X to 26.49 ug/L chl by in vivo fluorescence), indicating expansion of the net community at this locale. The community was a rich mixture of healthy looking diatoms and dinoflagellates.  Diatoms were the dominant group this week attributable to a Pseudo-nitzschia bloom comprised mainly of smaller delicatissima size class cells (100X! to 235,903 cells/L, 19.1% seriata, the later common in chains exceeding 20 cells). Dinoflagellates also increased in abundance and diversity again led by Akashiwo sanguinae (6.8X to 3,205 cells/L) and Cochlodinium spp. (14.6X to 3,451 cells/L, singletons and chains of 4 cells were present). A single 4 cell chain of Alexandrium was observed in live samples.

A beautiful Wednesday morning with dark blue waters offshore giving way to turbid, sediment and drift macroalgae laden waters around MWII. The sun was a welcome break between several days of late season rain squalls. Net chlorophyll was little changed from last week's observations while total chlorophyll plummeted (Net Fraction: 1.06X to 0.33 ug/L chl; Total: 0.19X to 7.74 ug/L chl by in vivo fluorescence). Sediment and detritus were dominant in todays sample. Underneath the dirt, the net phytoplankton community remained sparse, with diatoms gaining the upper hand in this weeks samples. Pseudo-nitzschia were common (ca 10X to 2,358 cells/L, 50% seriata, chains of 10 cells common) and joined by Pseudoguindaria recta, and Lauderia spp. Dinoflagellates were led by Akashiwo sanguinae (ca. 2X to 472 cells/L) and Cochlodinium spp. (0.13X to 236 cells/L, singletons and chains of 4 cells were present). No Alexandrium were observed in the MWII samples.

A dark sky blanketed dark jade green waters at MWII making a wet morning of sampling a little less dreary. Water temperature increased by ca 2oC since last observation. Chlorophyll also levels increased over last week's observations (Net Fraction: 3.6X to 0.31 ug/L chl; Total: 2.04X to 39.746 ug/L chl by in vivo fluorescence). An active community of small (<5u flagellates) were the likely dominant group this week. The net phytoplankton remained sparse, with dinoflagellates being led by Cochlodinium spp. (1,843 cells/L, singletons and chains of 6 cells were common). No Alexandrium were observed in the MWII samples. Pseudo-nitzschia were only observed in live samples (<200 cells/L, 100% delicatissima size class).

Overcast this am, but it was surprisingly clear looking out across the water (easy to see ML and PG).  Lots of surfers with the S swell and the CSL #s have increased over the past week.  Phytoplankton biomass in the net tow dropped off this week along with phyto diversity.  Assemblage was mostly Cochlodinium.  Only a handful of Alex cells in the petri today and the counts are down to something more “normal” for SCW.

Although the bay was under a blanket of marine layer, subsurface flashes of silver from minnow size fish feeding in dark calm waters added to the enjoyment of the day's sampling. Net chlorophyll levels were again lower in this week's samples, while whole water chlorophyll biomass increased (Net Fraction: 0.55X to 0.085 ug/L chl; Total: 1.59X to 19.47 ug/L chl by in vivo fluorescence). Phytoplankton were indeed sparse in net samples (1 cell = Present) with no clear dominant group. Dinoflagellates were led by Scrippsiella (common at ca 472 cells/L). No Alexandrium were observed in the MWII samples. Pseudo-nitzschia were only observed in live samples (<200 cells/L, 80% seriata class.

Sunny weather prevailed this week over the Monterey Bay and made for a pleasant (if not a few days late) morning of sampling at MWII. Small bait balls were being wrangled by a Greeb in blue green waters adding to the mornings entertainment. Net chlorophyll levels were lower in this week's samples (Net Fraction: 0.5X to 0.15 ug/L chl; Total: 0.53X to 12.22 ug/L chl by in vivo fluorescence), indicating low biomass in the net fraction (1 cell = Present). Although at low abundance, dinoflagellates led the net community, with Scrippsiella and Gymnodinium leading the pack (common at ca 1000 cells/L).  Dinophysis accuminata was also common (439 cells/L).  Surprisingly, based on the report of high Alexandrium counts on 5/1 at SCW, none were observed in the MWII samples. Pseudo-nitzschia were not observed in this week's samples.

Another beautiful morning of sampling off the MWII as our recent spell of warm weather continues. Water temperature increased by over 1oC since last observation. Net chlorophyll levels were sharply lower while total biomass was little changed from last sample (Net Fraction: 0.14X to 0.31 ug/L chl; Total: 0.91X to 22.94 ug/L chl by in vivo fluorescence). The net samples represented a mixed community of diatoms and dinoflagellates but small (<5u diam.) flagellates, likely Phaeocystis spp, were dominant in the background. The diatom community was led by Cylindrotheca spp and small Pseudo-nitzschia which continued to increase in abundance (ca 2.08X to 25,465 cells/L, 16.7% seriata morph).  Dinoflagellates, were led by Scripsiella and Akashiwo sanguinae.

Chlorophyll levels jumped upward from last observations (Net Fraction: 10.2X to 2.13 ug/L chl; Total: 2.21X to 25.26 ug/L by in vivo fluorescence), hinting that the recent winds brought something good into the bay. Diatoms dominated the net biomass, predominantly chain forming species again led by several Chaetoceros spp and Skeletonema spp.  Pseudo-nitzschia increased in abundance but shifted towards smaller species (ca 54.4X to 12,261 cells/L, 26.9% seriata morph).  Dinoflagellates, although rare overall increased in abundance and diversity as well.

A sunny, cool morning of sampling at MWII, fortuitously conducted during a pause in the strong onshore winds that hammered the bay on all day Tuesday. A combination of these winds and a low tide have stirred up the surface waters such that sediment and detritus fines were dominant in the sample.  Chlorophyll levels represented a loss in net biomass, but little change in whole water values (Net Fraction: 0.04X to 0.21 ug/L chl; Total: 1.01X to 11.43 ug/L by in vivo fluorescence). Although overall sparse living biomass in the net community, diatoms were dominant led by broken chains of Chaetoceros and Skeletonema spp. Pseudo-nitzschia were only observed in live samples ( at least 17 cells/L, 65% seriata morph).  Alexandrium spp, were observed in both fixed and live samples increasing to present (ca 56X to 255 cells/L). Water temperature increased by ca. 1oC over the past week.

A quiet morning of sampling at MWII, clearing clouds after overnight rains.  Surface waters remained relatively clear, yet chlorophyll levels jumped up from last week's lows (Net Fraction: 46.8X to 4.63 ug/L chl; Total: 2.55X to 11.23 ug/L by in vivo fluorescence). The large increase in net chlorophyll biomass is associated with another diatom bloom, this time led by Skeletonema spp (>20 cell chains abundant) and accompanied at lower abundance by Pseudo-nitzschia (119X to 53,847 cells/L, 75.9% seriata morph with healthy and motile >15 cell chains observed in live samples). Paired seriata morph cells with pigmented zoospores observed in live samples at rare levels. Alexandrium spp, were only observed as a 4 cell chain in live samples (ca 0.33X to 4 cells/L).

A lovely morning on MWII after a rainy Wednesday. Our first spring bloom was short lived with chlorophyll levels crashing from the high levels observed last week (Net Fraction: 0.02X to 0.099 ug/L chl; Total: 0.094X to 4.409 ug/L by in vivo fluorescence). Phytoplankton were sparse in today's samples with diatoms leading the way in species richness and abundance.  Thalassiosira spp led the way followed by a mix of Chaetoceros spp. Pseudo-nitzschia spp. also declined sharply in abundance to 'present' levels (0.007X to 453 cells/L, 50% seriata morph with healthy and motile >15 cell chains observed in live samples). Alexandrium spp although only observed in live samples (ca 12 cells/L) were active with several singlets and 4 cell chains present.

Our favorite time of year around Monterey Bay! Despite making the morning wharf commute under a heavy downpour, it was fortunately, the last of the overnight storms. Calm dark green waters masked a long period swell at high tide.  Chlorophyll levels heralded a spring bloom, spiking upward from observations last week (Net Fraction: 8.0X to 4.56 ug/L chl; Total: 9.16X to 46.68 ug/L by in vivo fluorescence).  While net sample filters where caramel brown, whole water filters were olive green tinted, hinting at a significant nanoplankton bloom. None-the-less the net samples were also rich with life. While diatoms were clearly dominant (Chaetoceros, Guinardia, Skeletonema, Pseudo-nitzschia), dinoflagellates were diverse at background levels, although also at higher abundance than last sample. Chain forming diatom species were obviously happy this week, with lengths in excess of 20 cells. Pseudo-nitzschia spp. were common (9.46X to 62,670 cells/L, 74.7% seriata morph with healthy and motile >15 cell chains).

Clear sunny weather following a day of strong WNW winds stirring up the bay was a pleasant change of pace for our original sampler.  Water was very turbid (ca 0.5m vis) with a strong surge. Chlorophyll levels were higher than our winter time lows (Net Fraction: 0.57 ug/L chl; Total: 5.1 ug/L by in vivo fluorescence).  While samples were dominated by sediments, they also contained a robust diatom community and a background of  dinoflagellates and protozoan grazers. Pseudo-nitzschia spp. were common (6,631 cells/L, 60% seriata with healthy and motile 5 cell chains) and joined by Guinardia and Chaetoceros spp.

A fortunate break between the strong storm sets impacting the Monterey Bay region, was more than welcome by our intrepid sampler during her last official visit to MWII. In spite of recent heavy rains and winds, the surface waters were surprisingly clear for the day's sampling. Consistent with this observation, net tow samples were essentially devoid of plankton and detritus. Chlorophyll levels were lower this week  (Net Fraction: 0.6X to 0.06 ug/L chl; Total: 0.3X to 0.88 ug/L by in vivo fluorescence).  Community abundance was again negligible, represented by a handful of diatoms, dinoflagellates and protozoan grazers. Pseudo-nitzschia spp. were only observed in live samples (<100 cells/L, 100% delicatissima size class, 2-3 cell chains).

The Monterey Bay region has received more than an inch of rainfall over the past few days, with more expected on the way. However grey clouds amassing over the Monterey Wharf belied a dry day on shore for todays sampling. Sustained high surf resulted in sandy, detritus filled surface water samples. Chlorophyll levels remained typical of our low biomass winter season  (Net Fraction: 0.099 ug/L chl; Total: 3.1 ug/L by in vivo fluorescence).  Community abundance was correspondingly negligible, represented by a handful of diatoms, dinoflagellates and protozoan grazers. Pseudo-nitzschia spp. were present at low absolute, but artificially high relative abundance this week (1,500 cells/L, 100% delicatissima size class).

With illnesses and conferences behind us, we are finally able to return our attentions to the happenings under the glorious Monterey Wharf II. High surf over the preceding week (3-8m Dominant Wave Height) resulted in sandy, detritus filled surface water. Chlorophyll biomass was typical of our winter season with low phytoplankton abundance conditions (Net Fraction: 0.20 ug/L chl; Total: 7.6 ug/L by in vivo fluorescence).  Community abundance was relatively low, and represented by a fairly even mix of diatoms and dinoflagellates. Pseudo-nitzschia spp. were present at low abundance this week (1,500 cells/L, 57% seriata size class). Dinoflagellates were led by a mix of Ceratium spp. Grazers were abundant and active in today's samples.

Another brisk, clear and sunny fall morning of sampling off the Monterey Wharf II, marred only by the haze and lingering smell of smoke from the current northern CA fire.  Surface water temperature rose by 1 oC compared to last sample. Chlorophyll biomass continued to seesaw, with todays biomass lower than last week's observations (Net Fraction: 0.5X to 0.81 ug/L chl; Total: 0.7X to  12.2 ug/L by in vivo fluorescence).  An exceptionally calm sea surface made along with low community biomass made for strikingly high water clarity compared to the past few weeks.  Community abundance was relatively low, and represented by a fairly even mix of diatoms and colorful dinoflagellates.

A beautifully brisk and sunny fall morning of sampling off the Monterey Wharf II. Surface water temperature was another degree lower compared to last sample. Chlorophyll biomass abruptly reversed trend, increasing from last week's sample levels (Net Fraction: 4.8X to 1.62 ug/L chl; Total: 2.0X to  18.8 ug/L by in vivo fluorescence).  Increased swell activity stirred up sediment and detritus around MWII and dominated the net samples.  While community abundance was relatively low, an increase in abundance and diversity of diatoms is associated with the increased chlorophyll biomass. Pseudo-nitzschia spp. led the diatoms (4.8X to 25,078 cells/L, 63% seriata size class) with a mix of Chaetoceros spp. close behind.

A thick marine layer and cool air made for a gloomy morning of sampling at MWII.  Chlorophyll biomass reversed its recent trajectory, decreasing significantly over last week's observations (Net Fraction: 0.18X to 1.89 ug/L chl; Total: 0.57X to 25.4 ug/L by in vivo fluorescence).  Dinoflagellates came back to rule the community, led by Certatium spp. along with a colorful assortment of Gyrodinium and Gymodinium. Cochlodinium, in chains of 2-4 cells were present. Diatoms declined from last weeks bloom represented mainly by single, chlorotic cells. This group was led by a mix of Chaetoceros and Pseudo-nitzschia spp., the later which sharply declined in abundance (0.08X to  16,290 cells/L, 87% seriata class).

The marine layer returned for Wednesday sampling at MWII. Fortunately, this gloom has been burning off for some glorious afternoons around the bay. Water temperature declined by ca 1oC over the week. Chlorophyll biomass continued on an upward trajectory, increasing significantly over last week's observations (Net Fraction: 5X to 10.8 ug/L chl; Total: 1.3X to 44.6 ug/L by in vivo fluorescence).  The phytoplankton community composition reflected a recent diatom bloom and decline in the relative abundance of dinoflagellates. Dinoflagellates were still led by Prorocentrum spp. and Certatium spp. Diatoms were healthy looking, with robust chloroplasts. This group was again led by Pseudo-nitzschia spp., which continued to increase in abundance and cell size (5X to  204,274 cells/L, 43% seriata class).  Epibiont laden delicatissima size class cells remained in mix.

Beautiful clear morning weather for sampling at MWII indicates that Fall weather might just be around the corner for the Central Coast. Chlorophyll biomass reversed it recent trend, increasing significantly over last week's observations (Net Fraction: 4.2X to 2.1 ug/L chl; Total: 2.5X to 35.3 ug/L by in vivo fluorescence).  The phytoplankton community increased not only in abundance but diversity, represented by an interesting mix of diatoms, dinoflagellate and silicoflagellates. Dinoflagellates were led by Prorocentrum spp (6,859 cells/L) and Certatium spp (2,572 cells/L). Though generally less abundant overall, diatoms were a healthy looking mix led by Pseudo-nitzschia spp., which bounced back from last week's low  (65X to  42,012 cells/L, 17% seriata class).  Epibiont laden delicatissima size class cells also returned to the mix, a sign of advection of offshore waters to this locale?

A thick marine layer, drizzly fog, typical Monterey Bay summer gloom, did not stop our intrepid sampler today. But alas, even the phytoplankton community seemed bummed by this weather. Chlorophyll biomass continued to decline (Net Fraction: 0.4X to 0.36 ug/L chl; Total: 0.67X to 13.9 ug/L by in vivo fluorescence).  Although at reduced biomass, dinoflagellates again ruled the net community, led by a mix of Prorocentrum species and the small gymnodinoid cell types observed last week. Diatoms were at best rare, with Pseudo-nitzschia spp., sharply declining in abundance  (0.28X to  643 cells/L, 67% seriata class).

What a beautiful morning on the Monterey Wharf II.  Puffy white scattered clouds on a blue sky framing a bright golden sun more than helped our intrepid sample get through hump day. Water temperature has risen 1.4oC. Net chlorophyll biomass continued to decline while total chlorophyll exhibiting little change in this week's samples (Net Fraction: 0.4X to 1.4 ug/L chl; Total: 0.97X to 20.8 ug/L by in vivo fluorescence).  Dinoflagellates ruled the net community, again led by small gymnodinoid cell types (38,154 cells/L). Diatoms were rare with Pseudo-nitzschia spp., increasing in abundance and decreasing in size (1.4X to 2,358 cells/L, 18% seriata class). Epibionts were observed on delicatissima size class cells as well as on several Chaetoceros chains.

At long last, a clear, sunny morning reminded our intrepid sampler that summer-like weather does come to MWII occasionally. Net chlorophyll biomass increased again while total chlorophyll continued on a downward trend (Net Fraction: 1.7X to 4.9 ug/L chl; Total: 0.7X to 25.8 ug/L by in vivo fluorescence).  The increase in net chlorophyll was attributable to a return of a healthy and diverse diatom community, led by several Chaetoceros species.  However, Pseudo-nitzschia spp. decreased in abundance with increasing representation of seriata size class species  (0.7X to 52,730 cells/L, 39% seriata class).

The summer pattern of overnight/morning fog continues has recently been giving way to sunny afternoons, but unfortunately, skies are now discolored with smokey haze from the northern California fires. None-the-less our intrepid sampler continues to interrogate the waters around MWII.  Net chlorophyll biomass increased while total chlorophyll continued on a downward trend (Net Fraction: 2X to 2.9 ug/L chl; Total: 0.8X to 39.4 ug/L by in vivo fluorescence). A diverse dinoflagellate community remains abundant in this week's sample. Prorocentrum spp. while increasing in abundance remain common  (1.7X to 12,217 cells/L) and Alexandrium spp were again present with numerous 2-4 cell chains moving through live fields. Pseudo-nitzschia spp. also increased in abundance with delicatissima size class species remaining thedominant forms (6X to 73,093cells/L, 6% seriata class). No epibiont laden Pseudo-nitzschia cells were observed in these samples. Water temperature declined by ca 1oC over the past week.

The Monterey Bay summertime 'blahs' continue with a misty damp and dense marine layer covering our intrepid sampler this morning at MWII. Net chlorophyll biomass declined from recent highs (Net Fraction: 0.33X to 1.45 ug/L chl; Total: 0.98X to 47.8 ug/L by in vivo fluorescence). While dinoflagellate abundance declined, this group remained dominant in the net plankton community. Prorocentrum spp. was still common  (0.14X to 7,930 cells/L) and Alexandrium spp were present with numerous 4 cell chains moving through the fields. Pseudo-nitzschia spp. increased in abundance with delicatissima size class species remained dominant forms (5X to 12,003cells/L, 5% seriata class). Again half of the delicatissima sized cells had a Christmas tree-like appearance being covered by, as yet, unidentified, non-pigmented protists.

Wharf water was all churned up this morning (and its real warm, 18.7C) resulting in a net tow full of detritus/debris and a drop in phytoplankton biomass.  The assemblage also shifted to mostly dinoflagellates.  Prorocentrum was the most abundant, but Ceratium and Cochlodinium were also strong contenders.  Pn (deli-size) was still around, but a majority had “Christmas tree light” epiphytes.

A cool breeze over the bay pushed out the morning marine layer, yielding to warm sunshine at the MWII. Chlorophyll biomass increased again and surface waters were visibly discolored with a dinoflagellate bloom (Net Fraction: 2.9X to 4.4 ug/L chl; Total: 1.6X to 48.8 ug/L by in vivo fluorescence). Colleagues at MBAC reported that the red tide patch had been moving back and forth through the wharf since Thursday of last week (7/19). Today's water samples consisted almost entirely of an eclectic mix of lively dinoflagellates. Prorocentrum spp. were dominant (50,586 cells/L) with Oxytoxum (7,073 cells/L), Dinophysis spp. (7,930 cells/L) and Ceratium spp. (3,858 cells/L) were present in high numbers as well. Pseudo-nitzschia spp. were rare, but delicatissima size class species remained dominant forms (0.01X to 2,357cells/L, <1% seriata class). Approximately half of the delicatissima sized cells were covered by, as yet, unidentified, non-pigmented protists giving the a christmas tree like appearance (last reported August 2017, pictures available). Water temperature cooled by a degree over the past week.

Summer gray continues to dominate our local skies making for a dreary and drizzly morning sampling at MWII.  Chlorophyll biomass remained elevated (Net Fraction: 0.71X to 1.5 ug/L chl; Total: 1.2X to 31.3 ug/L by in vivo fluorescence). A lively collection of diatoms and dinoflagellates accounted for a roughly equal proportion of numerical biomass. Pseudo-nitzschia continued to increase in abundance and remained dominated by delicatissima size class species (1.9X to 199,559 cells/L, 1% seriata class). The few observed seriata class cells were single and bloated with apparent chytrid infection.  A few of the delicatissima sized cells were covered by, as yet, unidentified, non-pigmented protists giving the a christmas tree like appearance (last reported August 2017, pictures available).

* Impressions *
A thick marine layer yet again hung over the Monterey Bay this morning, but this didn't deter local anglers on the MWII hitting a mackrel run.  Chlorophyll was precipitously lower than observed in last weeks samples (Net Fraction: 0.08X to 1.4 ug/L chl; Total: 0.17X to 19.1 ug/L by in vivo fluorescence). Straggly looking diatoms lingered and were joined by an assortment of dinoflagellates at roughly equivalent but, low abundances. Pseudo-ntizschia spp. abundance also declined sharply from last sampling  (0.03X to  3,789 cells/L, 41% seriata size class).
