Data from two Antarctic krill (Euphausia superba) 24-hour feeding experiments under ambient temperature and pCO2, ambient temperature and elevated pCO2, and elevated temperature and pCO2.

<p>Data from two Antarctic krill (<em>Euphausia superba</em>) 24-hour feeding experiments under ambient temperature and pCO2, ambient temperature and elevated pCO2, and elevated temperature and pCO2.</p>

<p>We conducted perturbation experiments to determine potential changes in feeding rates of Euphausia superba (32-41 mm) due to decreased pH and elevated temperature. Target pH was reached in the experiments via CO2 bubbling of seawater flowing through gas equilibration columns. The two feeding experiments differed in acclimation time.&nbsp; Krill in experiment 1 (Exp 1) and experiment 2 (Exp 2) were acclimated to treatment conditions for 48 hours and 21 days, respectively.</p>
