Morphometric data were collected for 417 Calanus finmarchicus copepods (stage CV), swimming activity data were collected using locomotor activity monitors for 469 Calanus finmarchicus copepods (stage CV) and oxygen consumption activity data were collected using a Loligo microplate respirometry system for 40 Calanus finmarchicus copepods (stage CV). All data were collected in the Fram Strait, Arctic Ocean, from two stations (F7 and D6) in August 2019, coinciding with the timing of early diapause in this species. Photographs were taken and experiments were conducted onboard RRS James Clark Ross. The data are reported in detail in Grigor et al., Torpidity as an indicator of overwintering diapause in Calanus finmarchicus. Funding was provided by the CHASE project (NE/R012733/1), part of the Changing Arctic Ocean (CAO) programme, jointly funded by the UKRI Natural Environment Research Council (NERC) and the German Federal Ministry of Education and Research (BMBF). Sampling and experiments were performed on the ... : Morphometric data: Collected for 417 Calanus finmarchicus copepods (stage CV) collected in the Fram Strait, Arctic Ocean. Swimming activity in the laboratory was measured in 225 epipelagic and 192 mesopelagic copepods from two stations (F7 and D6) in August 2019, coinciding with the timing of early diapause in this species. Copepods were photographed under a stereomicroscope after removal from the locomotor activity monitor experiments (see swimming activity dataset). Photographs were taken onboard RRS James Clark Ross. The following measurements were made; body size (prosome areas in mm2) lipid sac area, as well as lateral lipid sac area / prosome area (LA / PA ratios). Data are thus separated for copepods from each activity monitor allowing pairing with the other dataset. Copepods were sourced from epipelagic and mesopelagic depths for comparisons of diapause indicators at stations F7 and D6 in the Fram Strait (Greenland Sea). Copepods were collected from the water column using the Hydrobios® Mammoth ...
