| Summary: | 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. Funding: CLIMA project (Climatic Long-term Interactions for the Mass Balance in Antarctica) of the Italian National Program for Research in Antarctica. ... : 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. ... |
