In this study, we examined how CO2-driven acidification affected larval survival and condition in snow crab (Chionoecetes opilio), an important fishery species in Alaska. Ovigerous females were held in one of three treatments: ambient pH (~8.1), pH 7.8, and pH 7.5, through two annual reproductive cycles. Experiments on the effects of reduced pH on morphology; starvation survival; mass; and Ca, Mg, C, and N contents of the larvae were conducted in a design that fully crossed maternal treatment (pH at which the ovigerous females were held during embryo development) and larval treatment (which were the same 3 pH treatments). The complete methods, which should be read and understood prior to using this data, are under review as: Long, W.C., Swiney, K.M., Foy, R.J., 2023. Direct, carryover, and maternal effects of ocean acidification on snow crab embryos and larvae. PLOS ONE 18(10), e0276360. https://doi.org/10.1371/journal.pone.0276360
