Mesozooplankton collected by the Bark Europa in Gerlache Strait, Antarctic Peninsula

Mesozooplankton was collected with a vertically hauled Nansen 70V net in the Gerlache Strait and vicinity of Anvers Island. The net was deployed to a maximum depth of 50 m through hand-hauling. Specimens were preserved in 4% buffered formalin. Analysis was carried out through light microscopy of the entire sample, and specimens identified to the lowest possible taxonomic level including the identification of developmental stages.

Sampling was carried out as part of the REQUEST2021 T.A.S.K. (The Antarctica Scout Krill) project. The Nansen net was provided by the British Antarctic Survey as in-kind support. Sample analysis was carried out by Dr. Peter Ward, an e-fellow at BAS. REQUEST2021 was an official expedition of Kent Scouts (a county of the UK Scout Association), with further support from charitable donations.

Statement: Deployment depth was estimated according to the length of rope luffed into the water and the angle of the rope relative to vertical. Although 50 m was the nominal maximum depth, maximum depth attained is likely to be less in most instances.

A flow meter was not deployed with the net so volume of water sampled was estimated as the product of the opening area (diameter of 0.7 m) of the net and the amount of rope deployed below the sea surface. This will incur an error resulting from any turbulence, upwelling or downwelling currents present during the time of sampling and any clogging and inefficient filtering through the net.

Sample analysis was carried out to the lowest possible taxonomic level practicable, which was not always to the species level but sometimes went further also to include developmental stages.
