This study investigated the interactive efects of Ocean Warming and Ocean Acidification on Pacifc cod embryos and larvae by rearing fsh in a factorial experimental design at three temperatures crossed with two CO2 levels. The range of temperatures included cold (3 °C), mid (6 °C) and warm (10 °C) treatments, while an ambient and high (~ 1500 μatm) treatment were used for the CO2 levels. Collectively, these treatments spanned current and future ocean conditions within the Gulf of Alaska and Bering Sea regions of the eastern North Pacifc Ocean. Whole-animal traits, including mortality, growth, and condition, were measured throughout both the embryo and larval life stages. This dataset is included in the OA-ICC data compilation maintained in the framework of the IAEA Ocean Acidification International Coordination Centre (see https://oa-icc.ipsl.fr). Original data were provided by the author of the related paper (see Related to) to the OA-ICC data curator. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2024) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2024-07-31.
