Geological and Geochemical Analysis of Seabed Stability at the Norfolk Ocean Disposal Site. Part 2. Geochemical Analysis.
This study found that: the seabed at The Norfolk Disposal Site (NDS) is highly dynamic and sedimentation rates at different locations of the disposal site were not uniform; recent material with an age less than ten years was deposited at the site; source material for the sediments had varied with ti...

Summary: | This study found that: the seabed at The Norfolk Disposal Site (NDS) is highly dynamic and sedimentation rates at different locations of the disposal site were not uniform; recent material with an age less than ten years was deposited at the site; source material for the sediments had varied with time; depth profiles suggest either spatial inhomogeneity of sediment composition or movement of sediments by storms. Keywords: Open ocean disposal; Box core; Radiochemical analysis; Thorium isotope tracer; Comparison with geological; Sediment movement; Sedimentation; Depth profiles. |
