| Sediment trap moorings were deployed from September 21, 1997 through February 21, 1998 at three locations south of Australia along 140degreesE: at similar to47degreesS in the central Subantarctic Zone (SAZ) with traps at 1060, 2050, and 3850 m depth, at similar to51degreesS in the Subantarctic Front with one trap at 3080 m, and at similar to54degreesS in the Polar Frontal Zone (PFZ) with traps at 830 and 1580 m. Particle fluxes were high at all the sites (18-32 g m(-2) yr(-1) total mass and 0.5-1.4 g organic carbon m(-2) yr(-1) at similar to1000 m, assuming minimal flux outside the sampled summer period). These values are similar to other Southern Ocean results and to the median estimated for the global ocean by Lampitt and Antia [1997], and emphasize that... |
