Description

This dataset is a species list of different phytoplankton observed during the UNIS field course for AB202 in Kongsfjorden, near Ny-Ålesund. Four different locations were sampled over four days. The first site sampled was performed from the west side of the Ny-Ålesund pier, labelled Ny-Ålesund Pier West. The second site sampled was performed by boat, labelled ST1 (station 1), an area not previously surveyed. These first two sites were sampled the same day by the same group. The third site sampled was KB3 (Kongsfjorden Biology), a research site with annual sampling. The fourth and fifth samples had to be performed from the pier due to boat trouble. They were both performed at the east side of the pier, labelled Ny-Ålesund Pier East. All samples were analysed and identified to either species or genus. The individual count of each species was not recorded, due to very low abundancies of phytoplankton. Each group recorded which species they observed, and the dataset is therefore sorted into locations and which species were present.

Méthodes déchantillonnage

A 20µm phytoplankton net was used to gather samples. At the Ny-Ålesund Pier West, the net was lowered to two metres, and at Ny-Ålesund Pier East it was lowered to five metres. For ST1 the net was lowered to 20m, and 30m at KB3. However, due to difficult weather conditions and unsteady waters the phytoplankton net at KB3 was calculated to have reached 15 metres at a slope. Due to low phytoplankton abundance, 2-4 replicates were performed to concentrate the sample at each sampling event.

Etendue de létude The samples were collected from boat outside of Ny-Ålesund at KB3 and ST1 and from the pier at Ny-Ålesund in 2026 between 9th and 12th of April. At the Ny-Ålesund pier, two sampling sites were used. One at the east side of the pier, and one on the west side. The east side of the pier was sampled twice, once on the 11th and once on the 12th of April.

Description des étapes de la méthode:

  1. For samples taken from boat a 20µm phytoplankton net was lowered to approximately 20m. Two replicates were performed at both KB3 and ST1 to concentrate the sample. Due to weather conditions at KB3, 30m of rope was let out to account for water currents. Consequently, the sample was on a slope, instead of vertical through the water column. For sample events taken from the pier, a 20µm phytoplankton net was lowered by hand. 4 replicates were done at both sites at the pier. At the east side of the pier the net was lowered to 5m depth, and at the west side of the pier the net was lowered to 2m depth. After collection the samples were analysed by participating students with compound microscopes to identify organisms to genus or species. All identifications were recorded in the data sheet. Due to low abundance of organisms, all taxa were recorded as the lowest organism quantity.
