In the project MICROSNOW the ecological role of the small copepod Microsetella norvegica in the sub-Arctic Balsfjorden, Norway, was investigated. As background information, also the phytoplankton community composition was investigated twice in June 2017 and once in June 2018. At distinct depths (0, 10, 20, 50, 90, 120 m), water was collected with a 30 L GoFlow bottle and a subsample of 100 mL was preserved with acidic Lugol’s solution (1% final concentration) taken for later analysis. The remaining water was used for to investigate different developmental stages of the small copepod M. norvegica (data available under the projectID "Microsnow_2017_2018_Balsfjord" in GBIF).Sampling Description
Study Extent
All samples were collected at the same station. In 2017, phytoplankton were collected on two days within 1 week, while in 2018, phytoplankton samples were only collected once. On each day, water samples were collected at 6 depths (0, 10, 20, 50, 90, 120 m) for the phytoplankton community composition.Sampling
To determine the phytoplankton community composition in June 2017 and June 2018, a 30 L GoFlow bottle was successively deployed to 6 water depths (surface, 10, 20, 50, 90, 120 m). The collected water was brought on board and a subsample of 100 mL was transferred into a dark plastic bottle. The sample was preserved with 1 mL of acid lugol and then the sample was stored dark and cool until laboratory analysis within a few months.Method steps
- In the laboratory, subsamples were qualitatively and quantitatively analyzed according to the protocols described by Utermöhl (1958) and modified by Edler (1979). For this purpose, 10–50 mL subsamples were poured into the Utermöhl chambers, settled for 24 h in darkness, after which time the protists were counted under an inverted microscope equipped with phase and interference contrasts (Nikon Eclipse TE-300). Microplankton (>20 µm) was enumerated from the entire chamber surface at 100× magnification. Nanoplanktonic cells (3–20 µm) were counted at 400× magnification by moving the field of view along the length of three transverse transects. For the most numerous taxa, up to 50 specimens were counted, and the number of fields of view was considered individually for each count. Systematic affiliation of the identified taxa was verified against the World Register of Marine Species (WoRMS).
