Abstract:
Specimens of the marine calanoid copepod Acartia tonsa were exposed for five days under laboratory conditions to the isolated or combined effects of hypoxia and a marine heatwave event to test for their sex-specific life-history and physiological responses to these stressors. Four treatments were used: Control (C: 18 °C, 100 % O₂ sat.), Hypoxia (H: 18 °C, 35 % O₂ sat.), marine heatwave (MHW: 25 °C, 100 % O₂ sat.) and combined conditions (HMHW: 25 °C, 35 % O₂ sat.). This dataset compiles the physico-chemical parameters of the seawater (i.e. temperature, oxygen saturation, pH and salinity) in the aquaria holding the copepods during the five-day exposure experiment.

Comment:
The experiment was conducted in the Marine Ecological and Evolutionary Physiology Laboratory (MEEP) at the University of Quebec in Rimouski (UQAR), Rimouski, QC, Canada. Copepods were maintained following the stock culture culturing protocol described in Dam et al. 2021 (https://doi.org/10.1038/s41558-021-01131-5). Namely, approximately 200 copepods were kept in three 5 L aquaria filled with artificial seawater kept at a salinity of 28.4 ± 0.5. The physicochemical parameters of the seawater were the following: temperature of 18 ± 0.4 °C, oxygen saturation of 93.7 ± 6.0 %, pH NBS of 8.20 ± 0.09. The photoperiod was kept at 13h light: 11 h dark. Copepods were fed ad libitum with a mixture of three phytoplankters: Tetraselmis sp., Thalassiosira weissflogii and Rhodomonas salina.
