Extended Data Fig. 2: Biogeochemical characteristics of the mesopelagic zone (100 - 1000 m depths).
From: Distinct contributions of suspended and sinking prokaryotes to mesopelagic carbon budget

Particulate organic carbon (POC), dissolved organic carbon (DOC), nitrates plus nitrites (NOx) and ammonium (NH4) concentrations sampled with Niskin bottles (panels A, C, D and E) and sinking POC fluxes measured by the sediment traps over 4 days (panel B). These measurements were done on the five Process Studies Stations (PSSs) during the APERO cruise.
