Original data were extracted from tables in the related paper (see Related to) by 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 2026-06-18.</description></descriptions><geoLocations><geoLocation><geoLocationPoint><pointLongitude>-70.3051</pointLongitude><pointLatitude>41.7104</pointLatitude></geoLocationPoint></geoLocation></geoLocations></resource>
