 note = {In 1987, T.S.Kagoshima-Maru of the Faculty of Fisheries, Kagoshima University and the
University Pertanian Malaysia were engaged in the cooperative survey on the fish resources in
the area northwest of Borneo Island. The writers were in charge of surveying bottom
topography, sediments and bottom current. The following results were obtained.
1) Continental shelf margin is 175-200m in depth. Continental slope is rather gentle in the
western one-thirds of the surveyed area, and rapidly changes into the slope with higher angle
eastwards.
2) The bottom sediments of this area are mostly of very fine-grained sands. Their median
diameter (Md φ) is ranging from 2.46 to 3.68.
3) Sorting Coefficient (So) ranges from 0.605 to 1.635. This means well-sorted and rather
homogeneous sediments.
4) Skewnesses (Sk) of the most samples are plus value, indicating that the grain size
composition of the sediments is, as a whole, biassed toward fine grain sizes.
5) Bottom current velocity is generally low, and its direction is unsteady.},
