The particulate organic matter (Panel A) and surface particulate chemical oxygen demand (panel B) observed along a latitudinal (49° 38.3’ N, 5° 30.1’ W to 46° 1.0’ S, 49° 52.3’ W) transect in the Atlantic Ocean showed that the respiration quotient (Panel C) changes with latitude and oceanic biogeographical province (colored shading) .
