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. Dinoflagellates were active in the background with Cochlodinium (1,2, and 4 cell chains present) leading this group.

Clear blue skies, abundant schools of forage fish in the water and elegant terns dive bombing the sea surface after them made for quite the opposite of a spooky Halloween morning of sampling at the Monterey Wharf II.  Surface water temperature decreased by 2oC since last sample. Chlorophyll biomass decreased from last week's sample levels (Net Fraction: 0.5X to 0.34 ug/L chl; Tot9.4al: 0.5X to  ug/L by in vivo fluorescence).  Overall community abundance was low.  Dinoflagellates remain numerically dominant, led by a mix of Certatium, Cochlodinium and Dinophysis spp. Diatoms were diverse but generally rare at best. Pseudo-nitzschia spp. abundance was similar to last week's observations (1.1X to 5,787 cellsL, 30% seriata size class).

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). Dinoflagellates decreased in relative abundance, with Prorocentrum spp dropping to rare abundance.

Net tow was sort of similar to last week – the diatom/dinoflagellate community was about the same with Ceratium being the most abundant.  That said, the must abundant phyto in the net tow was a flagellate (maybe Heterosigma, but I could be wrong).  Pn were mostly deli-size and like at the MWII, the “Christmas tree lights” were absent from the cells this week.

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 anchovies are back and like 20 pelicans were hanging in the surf zone (or what usually is the surf zone as the waves were non-existent this am).  There was less detritus/debris in the net tow this week with a slight increase in phytoplankton biomass.  The assemblage remains mostly dinoflagellates, but things shifted a bit and Ceratium was the most abundant this 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.

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).

After several days of summer heat (>20oC on 7/10), this morning's sampling began with a thick, cooling marine layer spread over the bay.  Chlorophyll biomass was elevated compared to our last observations on 06/27/18 (Net Fraction: 1.5X to 2.1 ug/L chl; Total: 1.4X to 26.5 ug/L by in vivo fluorescence). A diverse assortment of diatoms and dinoflagellates accounted for a roughly equal proportion of numerical biomass. Pseudo-nitzschia was also elevated compared to last sampling and was comprised almost entirely of Pseudo-nitzschia delicatissima size class chains of 2-6 cell length (28X to 104,328 cells/L, 1% seriata class).

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.

A thick marine layer hung over the Monterey Bay this morning, but hints of a pre-summer sun filtered by the haze - gave promise to warm the kayakers, otters, birds and abundance of sea life dotting the bay. Chlorophyll was higher than observed in our last samples two weeks ago on May 30th (Net Fraction: 2.5X to 18.3 ug/L chl; Total: 2X to 115 ug/L by in vivo fluorescence). The high chlorophyll was associated with a diatom bloom consisting mostly of Chaetoceros spp. and Skeletonema spp. Few dinoflagellates were observed in the net tow. Pseudo-ntizschia spp. abundance increased from last sampling, with a preponderance of the smaller size class present (4.4X to  154,262 cells/L, 12% seriata size class).

Another foggy, windy and chilly morning at the Monterey Wharf II made our intrepid sampler thankful that this was the last sample event for this dreary month of May. Chlorophyll reversed course this week with a sharp increase in biomass (Net Fraction: 1.7X to 7.19 ug/L chl; Total: 3.18X to 57.78 ug/L by in vivo fluorescence). Diatoms and dinoflagellates were present in roughly equal abundances and species richness. Dinoflagellates were still led by A. sanguinae (1.56X to 4,681 cells/L, lysing cells were present) and joined by Prorocentrum spp. (2,229 cells/L). Pseudo-ntizschia spp. reversed course again, increasing in abundance, but decreasing in average cell size (3.76X to 35,221 cells/L, 49% seriata size class). These diatoms were joined by a mix of Chaetoceros spp.

Early morning drizzle gave way to a crisp and fresh air ambiance for sampling off the Monterey Wharf II.  Chlorophyll biomass continued its  week over week decline (Net Fraction: 0.38X to 2.11 ug/L chl; Total: 0.32X to 18.18 ug/L by in vivo fluorescence).  Dinoflagellates were dominant but continued to decline in absolute abundance were still led by A. sanguinae (0.4X to 3,000 cells/L) and Dinophysis spp (1,000 cells/L). The diatom Pseudo-ntizschia spp. reversed course again, decreasing in abundance and size (0.17X to 9,362 cells/L, 57% seriata size class).  Chain length was limited to 3-4 cells and empty frustules were observed.

A beautiful sunny and calm morning of sampling off the Monterey Wharf II.  Chlorophyll biomass exhibited a slight decline relative to last week's observations (Net Fraction: 0.84X to 5.5 ug/L chl; Total: 0.96X to 57 ug/L by in vivo fluorescence).  The net community was a good mix of healthy looking diatoms and dinoflagellates. Dinoflagellates, which declined in absolute abundance were still led by A. sanguinae (0.38X to 8,025 cells/L) and Prorocentrum spp (0.38X to 2,900 cells/L). The diatom Pseudo-ntizschia spp. reversed course increasing in abundance and size (6.22X to 56,845 cells/L, 90% seriata size class).  Chains greater than 10 cells in length were common.

A break in rain squalls associated with the atmospheric river impacting the CA coast offered a cloudy yet unusually balmy morning of sampling at MWII.  Surface water temperature increased by ca 2oC over the past week. Chlorophyll biomass was lower in this week's samples (Net Fraction: 0.36X to 0.59 ug/L chl; Total: 0.5X to 7.5 ug/L by in vivo fluorescence). An assortment of diatoms remained dominant in the net sample with few dinoflagellates at background levels. Pseudo-ntizschia spp increased in abundance (1.9X to 8,552 cells/L, 45% seriata size class). The increase in delicatissima size class abundance was attributed to P. americana associated with Chaetoceros spines.

Delaying sampling for a day, during this rainy week around the Monterey Bay, offered our intrepid sampler an opportunity to enjoy a dry and clear sky morning at MWII.  Chlorophyll biomass was slightly higher in this week's samples (Net Fraction: 1.3X to 1.6 ug/L chl; Total: 1.3X to 15.0 ug/L by in vivo fluorescence). Diatoms increased in abundance led by large Chaetoceros species (C. convolutus). Pseudo-ntizschia spp returned to the mix (4,501 cells/L, 60% seriata size class). Dinoflagellate dominance continued in today's samples, led again by Akashiwo, Prorocentrum,and Ceratium spp.  Pseudo-nitzschia spp abundance declined sharply (<0.04X to < 200 cells/L) and were only observed in live samples.

A pleasantly crisp and calm morning at the Monterey Wharf II offered a welcome respite from the strong winds over the past few weeks.  Chlorophyll biomass reversed course and was sharply lower in this weeks samples (Net Fraction: 0.17X to 2.02 ug/L chl; Total: 0.31X to 12.19 ug/L by in vivo fluorescence). As suspected from the visual impression, dinoflagellates dominated today's samples, led by  Akashiwo Prorocentrum,and Ceratium spp.  Pseudo-nitzschia spp returned to the community mix (4,501 cells/L 50% seriata size class).

Another sunny but very chilly morning for sampling at the Monterey Wharf II, following several days of strong onshore winds (W-WNW sustained >10m/s).  Chlorophyll biomass continued on its recent upward trend, again increasing from last sampling (Net Fraction: 2.5X to 12.1 ug/L chl; Total: 1.2X to 39.0 ug/L by in vivo fluorescence). The choppy surface waters were tinted by an associated bloom and the wharf area was impacted by a jellyfish swarm (Aurelia spp).  As suspected from the visual impression, dinoflagellates dominated today's samples, led by Prorocentrum, Akashiwo and Ceratium spp.  Diatoms, including Pseudo-nitzschia spp,  were at low abundance in the live samples, however no Pseudo-nitzschia were detected in fixed count samples.

So Punxsutawney Phil said 6 more weeks of winter, but the net tow says its spring!  Dramatic increase in phytoplankton biomass this week and a transition to a diatom dominated community.  Chaetoceros was the most abundant genus (several species represented).  Both size classes of Pn were represented, chains were all about 5 cells long and we even saw an 8 cell chain of Alex.  Also, Alex counts went up 2 orders of magnitude this week…

A pleasant cool breeze, offshore fog and clearing inland skies made for a dynamic coastal morning at the Monterey Wharf II.  Chlorophyll biomass continued on a downward trend (Net Fraction: 0.26X to 0.17 ug/L chl; Total: 0.96X to 6.78 ug/L by in vivo fluorescence). Although the bay has been presenting a calm surf, the region is being impacted by large (>10ft) long period swells, contributing to the high detrital and sediment load in todays samples. The sparse net community contained an assortment of dinoflagellates and diatoms in roughly equal representation.

The week began with a much needed heavy winter rain (over 2 inches around the bay), but today's sampling offered a cloudy but dry morning on the Monterey Wharf II.  Chlorophyll biomass further declined (Net Fraction: 0.59X to 0.63 ug/L chl; Total: 0.69X to 7.06 ug/L by in vivo fluorescence). The net sample had high detrital and sediment load associated with the recent storms. The sparse net community was again dominated by dinoflagellates with Ceratium spp and Gonyaulax spinifera at the top of the pack.  A mixed assemblage of diatoms was present in the background. No Pseudo-nitzschia spp were observed in live or fixed samples.

A low and grey marine layer, a perfectly calm sea and brisk morning air made for a unique experience at MWII for our intrepid sampler.  Surface water temperature increased by ca. 1 oC over the prior week. A visible red tide hinted at a return of a dinoflaglellate bloom. Correspondingly net and total chlorophyll increased sharply from last week's levels (Net Fraction: 8.9X to 7.5 ug/L chl; Total: 4.19X to 39.68 ug/L by in vivo fluorescence). The net community consisted almost entirely of dinoflagellate taxa led by Lingulodinium polyedrum (39,570 cells/L), Heterocapsa (29,894 cells/L),  and a mix of Prorocentrum spp (10,713 cells/L). Pseudo-nitzschia spp were only observed in live samples.

A pleasantly cool morning after several hot days on the central coast (31.9oC air temp at MWII on Tuesday!).  Our intrepid sampler got to enjoy dolphin pods splashing just offshore under a cloudless sky, while sampling noticeably clearer waters around MWII.  Net and total chlorophyll declined from last week's levels (Net Fraction: 0.33X to 0.24 ug/L chl; Total: 0.49X to 7.8 ug/L by in vivo fluorescence).  The net community, at far lower biomass than recent observations continues to be dominated by dinoflagellates by a few taxa led by Prorocentrum micans, Lingulodinium polyedrum, and Cochlodinium spp, all in low abundance. Pseudo-nitzschia spp was only observed in live samples and other diatom taxa were equally rare.

Grey clouds and heavy fog again filled sky over the  Monterey Commercial Wharf this morning.  Cooler surface water temperature prevailed this week and coincide with a 'bloom' of stinging nettle jellyfish (Chrysaora fuscescens). Net and total chlorophyll remained near last week's levels (Net Fraction: 0.95X to 0.73 ug/L chl; Total: 1.1X to 15.94 ug/L by in vivo fluorescence).  The net community continues to be dominated by dinoflagellates, and surface expression of this redtide was observed around MWII, during warm sunny days earlier this week.  Prorocentrum spp. (1.9X to 7,652 cells/L) and Akashiwo sanguinae (7.4X to 5,187 cells/L) led the dinoflagellate community. Pseudo-nitzschia spp was not observed and the diatom community was general sparse.

Crystal clear skies and warm air made for a lovely morning of sampling at the Monterey Wharf.  Net and total chlorophyll increased from last week's lows (Net Fraction: 3.3X to 1.65 ug/L chl; Total: 3.4X to 23.73 ug/L by in vivo fluorescence).  This upward spike in chlorophyll biomass was associated with a renewal of a dinoflagellate bloom led by a mix of  Prorocentrum spp (20,041 cells/L). Akashiwo sanguinae, Ceratium spp., Cochlodinium spp. and Dinophysis spp., were present at lower absolute abundances. A single epibiont laden Pseudo-nitzschia spp cell and other diatoms represented the virtually absent diatom community in today's samples.

After a heat wave swept through the central coast region over the Labor Day weekend (an air temperature high of 30.4 oC recorded at the MWII on 9/2!), the return of the marine layer over the wharf this morning was a welcome relief. Net chlorophyll and total chlorophyll were similar to last week's observations (Net Fraction: 0.84X to 0.79 ug/L chl; Total: 1.14X to 14.16 ug/L by in vivo fluorescence).  Dinoflagellates and diatoms were active and present in roughly equal proportions. Dinophysis spp. and Prorocentrum spp. were common in live samples. Pseudo-nitzschia spp reversed from recent trends, increasing sharply in abundance (24X to 23,342 cells/L 76% seriata size class).  Epibiont laden Pseudo-nitzschia chains also returned in low numbers.

Another thick marine layer made for a dreary sampling morning on the Monterey Wharf II, but hopes of afternoon clearing kept our intrepid sampler's spirits high. Surface water temperature declined by over 2oC during the past week. Net chlorophyll was little changed while total chlorophyll increased from last week's levels (Net Fraction: 0.95X to 0.32 ug/L chl; Total: 1.35X to 35.8 ug/L by in vivo fluorescence).  Dinoflagellates remained dominant in the net sample, led by a bloom of small (10x15um) cells tentatively ID'd as a Heterocapsa spp.  Dinophysis spp were present, while Alexandrium spp and Cochlodinium spp were observed at background levels. Pseudo-nitzschia spp continued to decrease in abundance (0.17X to 3,826 cells/L 100% seriata size class).  While no delicatissima size class cells were encountered in count samples, the majority (>80%) of delicatissima size class chains in live samples were again covered with small stalked heterotrophic flagellates.

A thick and low marine layer made for a damp morning of sampling off the Monterey Wharf II. Surface water temperature increased by over 2oC. Net and total chlorophyll declined sharply from last week's levels (Net Fraction: 0.09X to 0.34 ug/L chl; Total: 0.77X to 26.43 ug/L by in vivo fluorescence).  Pseudo-nitzschia spp continued to decrease in abundance and size (0.13X to 22,506 cells/L 27% seriata size class).  Intriguingly, the majority (>60%) of delicatissima size class chains were covered with small stalked heterotrophic flagellates (no chlorophyll detected).

Phytoplankton assemblage shifted to mostly dinoflagellates this week.  We’d love to say which one, but we’re not sure, so there are some images attached – these 2 were by far the most abundant today.  The Alexandrium count tripled this week, saw mostly 2 and 4 cell chains.
Also, our friends at the county office reported some red tides south of the wharf (Seabright and Aptos).

Gusting winds churned up the water and chilled the air, despite clear and sunny skies, at the Monterey Wharf this morning. 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. Pseudo-nitzschia spp. decreased in overall abundance and represented by a near even split in abundance of delicatissima and seriata size classes (0.8X to 28,294 cells/L, 42.5% seriata size class).

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.

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.
