Fatty acid composition (relative proportions in %) of 4-day old Calanus hyperboreus nauplii from mothers collected in the Northern Barents Sea

This dataset compiles Fatty Acid composition (relative proportions) of 4-day old Calanus hyperboreus nauplii from mothers collected in the Northern Barents Sea. Gravid Calanus hyperboreus females were collected from the Northern Barents Sea during the Q1 Nansen Legacy Seasonal Cruise in March 2021. After hatching, 4-day old Calanus hyperboreus nauplii were used for a short-term incubation assay (24h), exposing the nauplii to acidification (pH 8.01 and 7.50) and warming (0°C and 3°C), both individually and in combination. Nauplii larvae were added to each replicate at a density of ~0.6 larvae mL-1. The bottles were kept in the dark in incubators at the target temperature for 24 hours. After the incubation, all larvae from each treatment were extracted and checked for survival, and the remaining individuals were stored in Eppendorf tubes, freeze-dried, and kept at -80°C for lipid content analysis.
