<p>The investigators used a novel experimental approach that combined bi-weekly sampling of a wild, spawning fish population (Atlantic silverside <em>Menidia menidia</em>) with standardized offspring CO2 exposure experiments and parallel pH monitoring of a coastal ecosystem. They assessed whether offspring produced at different times of the spawning season (April to July) would be similarly susceptible to elevated (1100 uatm, pH_NIST = 7.77) and high CO2 levels (2300 uatm, pH_NIST = 7.47). Early in the season (April), high CO2 levels significantly (p &lt; 0.05) reduced fish survival by 54% (2012) and 33% (2013) and reduced 1 to 10 d post-hatch growth by 17% relative to ambient conditions. However, offspring from parents collected later in the season became increasingly CO2-tolerant until, by mid-May, offspring survival was equally high at all CO2 levels.</p> <p>This dataset provides the source data to:<br /> Murray, Christopher S; Malvezzi, Alex; Gobler, Christopher J; Baumann, Hannes. 2014.
