| Abstract: | The t-s diagram is a weighty tool for distinguishing water masses.But the increase of investigation data causes the limits of point-sets on the diagram to be more fuzzy.Particularly,it is difficult to divide water masses in,shallow water areas intuitively from the t-s diagram.The clustering method is applied widly because it can partly overcome the above mentioned difficulties.However,the order of data input may sometimesaffect merging results.We suggest a clustering method with the fuzzy density,which isnot affected by the order of data input.The definition of fuzzy density for points andits calculating method are given in this paper The fuzzy density clustering is made,the merging results and the distinction of water masses are discussed. |
