| Summary: | An array of five bottom-tethered moorings with 19 PARFLUX time-series sediment trap at three depths (1 and 2 km below the surface, and 0.7 km above the sea-floor) was deployed in the western Pacific sector of the Southern Ocean, along 170°W. The five stations were selected to sample settling particles in the main hydrological zones of the Southern Ocean. The sampling period spanned 425 days (November 28, 1996-January 23, 1998) and was divided into 13 or 21 synchronized time intervals. A total of 174 sequential samples were recovered and analyzed to estimate fluxes of total mass (TMF), organic carbon, carbonate, biogenic silica, and lithogenic particles. The fluxes of biogenic material were higher than anticipated, challenging the notion that the Southern Ocean is a low-productivity region. Organic carbon fluxes at 1 km depth within the Polar Frontal Zone and the Antarctic Zone were relatively uniform (1.7-2.3 g/m**2/yr), and about twice the estimated ocean-wide average (ca. 1 g/m**2/yr). Carbonate fluxes ... : Supplement to: Honjo, Susumu; Francois, Roger; Manganini, Steven J; Dymond, Jack R; Collier, Robert W (2000): Particle fluxes to the interior of the Southern Ocean in the Western Pacific sector along 170°W.
