Seawater carbonate chemistry and within- and transgenerational stress legacy effects of ocean acidification on red abalone (Haliotis rufescens) growth and survival


We assessed longer-term ocean acidification (OA) effects in red abalone (Haliotis rufescens) using a multi-generational split-brood experiment. We spawned adults raised in ambient conditions to create offspring that we then exposed to high pCO2 (1,180 μatm; simulating OA) or low pCO2 (450 μatm; control or ambient conditions) during the first three months of life. We then allowed these animals to reach maturity in ambient common garden conditions for four years before returning the adults into high or low pCO2 treatments for 11 months and measuring growth and reproductive potential.

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2022) 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 2024-01-15.
