Abstract:

This dataset contains measurements of survival, escape performance, and oxygen consumption for the copepod Calanus finmarchicus following short-term exposure to NaOH-dosed seawater intended to simulate transient exposure during ocean alkalinity enhancement (OAE) field deployments. Late-stage copepodites (C4–C5; "juveniles") and adult females (C6) were exposed to two elevated pH/total alkalinity (TA) conditions: pH 10.5 (~5,000 µmol kg⁻¹ TA) for 1, 5, or 10 minutes and pH 9.0 (~3,150 µmol kg⁻¹ TA) for 1, 15, or 30 minutes, alongside an ambient control: pH 8.0 (2,150 µmol kg⁻¹ TA). Survival was recorded immediately after exposure and during subsequent monitoring through 72 hours post-exosure (hpe). Escape response (ability to initiate an escape jump) was assessed immediately post-exposure and at follow time points at 24 and 72 hpe. Routine metabolic rate was quantified via microplate respirometry as oxygen consumption following a 10-minute exposure to pH 10.5, measured immediately after exposure for both life stages and again at 12 hpe for juveniles. The dataset provides carbon chemistry measurements, survival and escape response measurements, and oxygen consumption measurements.

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 downloaded from Dryad (see Source) 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 2026-06-10.
