Fig. 4: Vertical particulate organic carbon (POC) export fluxes induced by an intensifying cyclonic eddy and a submesoscale front.
From: Efficient biological carbon export to the mesopelagic ocean induced by submesoscale fronts
a, b Integrated POC from the base of the mesopelagic layer (900 m) to depth z, with z = [150 200 300 400 500] m for CE 2 and z = [170 200 300 400 500] m for the front. c, d Changing rate of the integrated POC over time. e, f Net rate of change of the averaged AOU. g, h Enhanced POC export fluxes. (a, c, e and g) are in CE 2, and (b, d, f and h) are at the front. The blue and orange solid lines in a, b represent linear regression lines of the POC inventories during the intensifying and mature (or decaying) stages, respectively. The blue and orange areas in a, b correspond to the intensifying and mature (or decaying) stages, respectively. The black dashed lines and error bars in c–h correspond to the euphotic zone depth and one standard deviation, respectively. The red areas in c–h represent the euphotic zone. The b values in g–h are shown as the mean ± 1 standard deviation. Source data are provided as a Source Data file.
