Surface sediments on the continental shelf and upper slope off the west coast of the South Island, New Zealand, from north of Karamea Bight (40°45'S) to the Whataroa River mouth (43°07'S) consist almost entirely of sands and muds. Inshore (< 50 m depth) sediment is predominantly fine sand to coarse silt. Silt-clay content increases towards mid-shelf depths, and areas of mud occur at depths of about 90-140 m. Sediments tend to become coarser again on the outer shelf, and sandy mud or muddy sand covers the outer shelf and upper slope. The west coast shelf experiences a high input of fluvial sediment, probably c. 12-26 × 10 6 tonnes y -1 for the study area. Sedimentation rate on the shelf is estimated to average at least 1-2 mm y -1 . Sedimentation is probably appreciably lower than this in the north of the area and higher in the south, and this is reflected in shelf grain-size parameters and sediment carbonate content. There are north-to-south decreases in mean grain size and in the ranges of sorting and skewness: shelf sediments tend to become finer and more uniform in texture towards the south. Carbonate content ranges from 0-70%, generally increasing with depth, but with a marked north-south contrast. In the north, carbonate values increase to c. 15% by 200 m depth and to 60-70% by 650-700 m, whereas off the southernmost transect, carbonate values are < 5% by 500 m and reach only c. 40% by 1100 m.
