At three stations, water samples were collected at 12 depths throughout the water column using standard 12 L Niskin-type bottles attached to a CTD rosette and represented the different pelagic zones: 25 m and 100 m (epipelagic), 250, 500, 750 and 1,000 m (mesopelagic), 1,500- 3800 m (bathypelagic; here different depths were sampled due to differences in bathymetry), and 4,000, 4,500 and 5,000 m (abyssopelagic). Temperature, oxygen, and pressure were measured using a Sea-Bird SBE 9-plus CTD system (Sea-Bird Electronics, Inc.), and chlorophyll a (Chl a) concentrations were detected using a WETStar fluorometer (WET Labs).PCA1 loadings used for DI calculation
