In order to understand the vertical transport of particulate matter, suspended and settling particles were collected along a meridional transect between 46°N and 35°S and an equatorial longitudinal transect between 135°E and 175°E in the Pacific. The low COrganic/N atomic ratios (<8.2) of suspended particulate organic matter (OM) and good correlation between particulate organic carbon (OC) and chlorophyll-a confirmed that the suspended particulate OM in the surface water was mainly produced by phytoplankton. Only 0.1–3.2% of primary production was transported to 1.3 km water depth in the boreal central Pacific. All data on settling particles (excluding deep trap data) showed strongly positive correlation between total mass and OM fluxes with high correlation factor of 0.93. Biogenic opal-producing plankton, mainly diatoms were responsible for most of the vertical transport of particulate OM in association with higher COrganic/CCarbonate ratios in the subarctic and equatorial hemipelagic regions in the ... : Supplement to: Kawahata, Hodaka (2002): Suspended and settling particles in the Pacific.
