Replication Data for: Seasonal dynamics of mesozooplankton biomass over a sub-Arctic continental shelf.
The data set presents taxon specific biomass and individual length measurements of mesozooplankton. Mesozooplankton samples were collected over a 12-month period at 3 stations over the Vesterålen shelf with a WP2 net (200 µm mesh) and preserved in borax buffered formalin. The measured biomass was st...

The data set presents taxon specific biomass and individual length measurements of mesozooplankton. Mesozooplankton samples were collected over a 12-month period at 3 stations over the Vesterålen shelf with a WP2 net (200 µm mesh) and preserved in borax buffered formalin.

Mesozooplankton research in high latitude ecosystems tends to focus on different life stages of Calanus spp. due to its biomass dominance and trophic roles. However, a complex seasonal succession of abundant smaller mesozooplankton taxa suggests that the ecological functioning of the mesozooplankton communities is more complicated. We studied the year-round taxon-specific biomass measurements and size distributions of mesozooplankton on a sub-Arctic continental shelf based on formalin preserved samples.
