Abstract:
Faecal pellets and eggs of Antarctic silverfish have been collected over the seasons using a sediment trap deployed on 1998 in Terra Nova Bay, Ross Sea, Antarctica in the frame of the National Italian Antarctic Research project (PNRA). Antarctic silverfish (ASF) accounts for over 90% of the local fish communities in the Southern Ocean costal area. Samples have been investigated in order to quantify the contribution of fish faecal pellets and eggs to the export of carbon.

| Quality: | CHN analyser was calibrated using an acetanilide calibration standard with a known % C and % N of 71.09 % and 10.36 % respectively. Standards were interspersed regularly between samples to measure and correct for drift. Analytical precision was better than 1.0 % for POC. |
|
| Lineage: | Sediment trap samples were collected during a cruise on the ITALICA research vessel. The traps were deployed in TNB Polynya on a mooring platform (mooring L, bottom 998 m) at 160 m depth during 1999. The sample carousel of the sediment trap was set up to rotate at intervals of 15 days over the whole year. Upon recovery, faecal pellets and eggs samples were investigate in term of abundance, degradation state, class size using an optical microscope. Carbon content was determined using a CHN analyser. | |
