Antarctic krill (Euphausia superba) growth data collected during an experiment where krill were allowed to molt once in ambient conditions then placed in individual bottles maintained at one of six target treatments: 1) Ambient temperature (0 degrees C) and ambient pH (8.00); 2) Ambient temperature (0 degrees C) and pH = 7.50; 3) Ambient temperature (0 degrees C) and pH = 7.10; 4) Elevated temperature (3 degrees C) and ambient pH (8.00); 5) Elevated temperature (3 degrees C) and pH = 7.50; 6) Elevated temperature (3 degrees C) and pH = 7.10. The bottles were incubated until the either the krill molted a second time or the experiment ended (after 26 days).
