The Hakai Institute Oceanography Program has been monitoring surface (0-1 or 5m depth) protistan plankton community composition, via optical microscopy, at a fixed location in the northern Salish Sea (Strait of Georgia) since 2016. Data were collected to characterize and monitor phytoplankton community composition and investigate links to environmental/physical/chemical drivers, the food web and carbon dynamics. Additionally, data were used to support group level phytoplankton composition derived via HPLC phytoplankton pigment analysis and validate remote sensing products.Purpose
The dataset was developed to investigate protistan plankton (primarily phytoplankton) community composition and variability and links to environmental/physical/chemical drivers, the food web and carbonate chemistry. Additionally, the data were collected to support HPLC phytoplankton pigment analysis and remote sensing.Sampling Description
Study Extent
Data were collected in surface waters (0-1 or 5 m depth) at a fixed location (QU39) in the northern Salish Sea (Strait of Georgia) on a weekly to bi-weekly period throughout the year.Sampling
Water samples were collected at 0-1 or 5 m depths using a Niskin bottle from small research vessels (less than 40 ft). Sample water was transferred into 250 mL amber glass bottles and immediately fixed using Lugol's acid-iodine solution (1% concentration) (Edler & Elbrächter 2010; Del Bel Belluz et al., 2021). The use of acidic Lugol’s solution removes CaCO3 containing cells (i.e. coccolithophores) and these species were not enumerated. Sample were kept cool and stored in a dark fridge until analysis was performed. Analysis was performed at LCLJ Marine Ecological Services by Dr. Louis Hobson. Protistan plankton were enumerated with the Utermöhl method using 50 mL settling chambers and phase contrast microscopy on an inverted light microscope (Edler & Elbrächter 2010; Hobson & Galbraith, 2018). The analyst was able to resolve species down to approximately 4 μm in size.Quality Control
Some samples, particularly those from the beginning of the timeseries, were stored for up to 2-3 years prior to analysis. The analyst did not see signs of weakened preservative or cell degradation, but storage time should be considered as degradation can bias results (Williams et al., 2016). In the occurrence extension, the dateIdentified column was used to specify a date range of when each sample was analyzed and the taxonomic identifications determined. Exact analysis dates are not available. Data have been broadly compared to functional group level phytoplankton biomass derived from HPLC pigments and chemotaxonomic analysis and show general agreement (Del Bel Belluz et al., 2021). More detailed comparisons are being performed and additional information will be added when available.Method steps

Additional info
The published data were used to support HPLC phytoplankton pigment characterization of phytoplankton community composition in Del Bel Belluz et al. (2021). The link to this work is provided in the bibliographic citations.Taxonomic Coverages
We targeted autotrophic protists, but data include mixotrophic and heterotrophic species including ciliophora and small metazoa. The analyst was able to resolve species as small as approximately 4 um.
