Dataset: Rotation order parameters in each trial of Antarctic krill in lab experiments at Palmer Station, Antarctica in November 2022.

We deployed on the R/V Laurence M. Gould to Palmer Station, Antarctica in October - December 2022. On the way, we collected krill using an Isaac-Kidd Midwater Trawl net at the following locations: 63°06.5′ S, 61°46.6′ W (on October 5th, 2022) and 64°37.9′ S, 62°14.5′ W (on October 6th, 2022). Krill were kept in two tanks with a continuous seawater supply on the boat until being transferred to holding tanks at the Station. Additional krill were collected from Wilhelmina Bay (64°42.0′ S, 62°16.6′ W) on November 12th by the R/V Nathaniel B. Palmer, transported to Palmer Station, and added to the same holding tanks filled with filtered seawater (100 µm).
