Abstract:

This dataset comprises measurements of microbial community respiration, derived from electron transport system (ETS) activity assays, in discrete water samples collected with Niskin bottles. ETS activity (mmol O2 m⁻³ d⁻¹) was determined enzymatically as a proxy for aerobic microbial and planktonic respiration, and respiratory oxygen consumption (RO2, mmol O2 m⁻³ d⁻¹) was subsequently calculated by applying respiration-to-ETS conversion factors of 0.75 for samples from the epipelagic zone and 0.086 for samples from the mesopelagic zone. Each of the 219 sampling stations was additionally assigned to an open-ocean biogeochemical province following the classification of Reygondeau et al. (2018). Samples were collected at depths ranging from 5 m to 4539 m water depth during thirteen research cruises carried out between November 2006 and April 2025: RODA-I (2006), RODA-II (2007), CAIBEX and CAIBOX (2009), HOTMIX and PUMP (2014), FLUXES I (2017), TRATLEQ1/M158 (2019), e-IMPACT1 and e-IMPACT2 (2022), APERO (2023), MICOLOR2 (2024) and OceanICU (2025). The combined geographical coverage extends across the eastern boundary upwelling system off northwest Africa (Canary Upwelling System, Cape Blanc, Canary Eddy Corridor), the North Atlantic Subtropical Gyre, the equatorial Atlantic, and a transect across the eastern South Atlantic and equatorial Atlantic between Walvis Bay (Namibia) and the Canary Islands; the HOTMIX cruise additionally sampled the eastern Mediterranean Sea before transiting into the Atlantic.
