Описание
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).

Данные проекта
Vertical export of organic carbon from pelagic to benthic ecosystems consists mainly of copepod faecal pellets and detrital aggregates (marine snow). However, it is estimated that 20-70 % of the aggregate-associated carbon is degraded by grazing organisms within the euphotic zone. One copepod species believed to play a vital role in particle flux reduction is Microsetella norvegica, but little is known about its ecology and biology. In the first year (2017) of MICROSNOW, we successfully completed high-resolution field-investigations focusing on the role of M. norvegica for regulating the pelagic-benthic coupling in Balsfjord. More specifically, we investigated the zooplankton community composition, aggregate distribution, hydrographical and chemical properties of the water column and vertical carbon fluxes. Experiments on M. norvegica egg hatching and respiration rates at 4 different temperatures, grazing experiments and behavioural studies were successfully completed and data are now being processed. In the second year of the project we will continue building a strong data-set by including new complementary investigations. We will also focus on dissemination of results through outreach and publication. Novelties within the project are: 1) high-resolution in situ mapping of marine snow and copepods, 2) identifying interactions between sinking particles and copepods through in situ video-observations and experiments and 3) increased knowledge on M. norvegica biology and its role for pelagic-benthic coupling. This is a timely approach in the context of the future role of coastal marine ecosystems as a sink or source for atmospheric CO2, and for building knowledge on the resources available for harvestable species.

Методы сбора
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.
| Охват исследования | 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. |

Описание этапа методики:
- 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).
