Fluxes and composition of settling particles during summer in an Antarctic shallow bay of Livingston Island, South Shetlands
7 pages, 7 figures, 1 table A moored experiment using a sediment trap was conducted at Johnson's Dock, Livingston Island from 11 December 1997 to 24 February 1998, as part of the EASIZ Programme activities carried out at the Juan Carlos I Spanish Antarctic base. Total mass vertical fluxes range...
