| During a six-year (1978-1984) sediment trap study in the northwestern Mediterranean off the coast of Monaco, large variations in mass flux and carbon flux through 100 and 150 m were observed with maximum flux values occurring in late winter or early spring and minimum flux in late summer. Total particulate carbon flux was linearly related to mass flux. During March through October total particulate carbon flux represented, on average, approximately 7 % of the mass flux, whereas from November through February it averaged about 4.7 %. From recent organic carbon content data collected in the same region, it was estimated that approximately 5 % of the total mass flux through 100 and 150 m in calm seas was organic carbon (calm seas were prevalent during March... |

| Sediment trap experiments were conducted to assess the production, disintegration and downward flux of zooplankton fecal pellets in the upper 500 m water column of the anticyclonic gyre off Shikoku, Japan. The particulate organic carbon (POC) flux decreased from 53.7 mgC M-2 d-1 at 50 m to 23.7 MgC M-2 d-1 at 500 m. The POC flux at the bottom of the euphotic layer (100 m) was 37.9 mgC m-2 d-1, which was equivalent to about 5 % of the daily primary production in the gyre. The estimated pellet carbon flux accounted for 0.4-1.7 % of the total POC flux. The pellet flux rapidly decreased in the upper 150 m layer, in parallel with the decrease in zooplankton abundance. A mid-depth peak of pellet flux, not associated with a noticeable population of zooplankton,... |
