Specimens recorded during the HHUMLT24 cruise on RV Helmer Hanssen Longyearbyen – Tromsø, July 3–10, 2024

Study Extent

A one-time research cruise from Longyearbyen - Tromsø through the Barents Sea

Sampling

The HHUMLT24 cruise onboard R/V Helmer Hanssen was an initiative by The Arctic University Museum of Norway (UMAK, UiT). Sampling was conducted for the following four projects: 1. The Scalidophora of Norway, 2. The role of microRNAs in animal evolution, 3. The diversity of benthic fauna around Svalbard and the Barents Sea, 4. Reconstruction of past ecosystems using sedimentary ancient DNA. For the first project, which aimed to sample scalidophoran fauna, primarily kinorhynchs, for the Scalidophora of Norway project funded by Artsdatabanken, box cores were taken. The second project employed plankton nets, box cores, and a triangular dredge. The third project used samples from box cores, plankton nets, and a triangular dredge to collect marine macrofauna for the museum collections. All macrofauna present in plankton nets, box cores, and triangular dredge samples were photographed, and records were uploaded to GBIF. The fourth project took gravity cores.

Quality Control

All species identifications were double checked by taxonomic experts.

Method steps

1. Sampling on the ship with subsequent species identification in the lab using stereo microscopes and updated taxonomic literature.
