Seawater carbonate chemistry and shell mineralogy, epibiont abundance, and growth of juvenile American lobster Homarus americanus


We examined the combined effects of ocean warming and acidification on shell mineralogy, epibiont abundance, and growth in early benthic juveniles of American lobster Homarus americanus H. Milne Edwards, 1837 (Decapoda: Astacidea: Nephropidae), a commercially important species. Lobsters were grown under six different temperature/pCO2 treatment conditions over 52 days (three replicates per treatment) aligned with environmentally relevant as well as predicted future extremes.

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 2024-03-14.
