Diatoms from SAZ Sediment traps

OBIS Australia Open in mapper Explore occurrences

The SAZ project organised by the Antarctic CRC has a continuing program of moored sinking particle trap studies in the Sub-Antarctic and Polar Frontal zones southwest of Tasmania along 140 E. The first deployment obtained weekly or higher resolution samples through the austral summer from September 1997 through February 1998 at three locations: the central Sub-Antarctic Zone (47 S, traps at 1000, 2000, and 3800m depth), the Sub-Antarctic Front (51 S, 1 trap at 3300m ) and above the Southeast Indian Ridge in the Polar Frontal Zone (54 S, 2 traps at 800 and 1500m). The particles were analysed for total mass, inorganic carbon, total carbon, nitrogen, silicon, and aluminium. Hence values for organic carbon, biogenic silica, and lithogenics were obtained, and the mass fluxes calculated. This report details the sites, moorings, data from the current meters and sediment traps, and results of analyses performed on the collected sediment trap material.
