Abstract

Water samples were collected quarterly, and elements in marine water were analyzed between January 2022 and December 2022 using The Anwar boat. Eight elements were measured in addition to the salinity concentration. The highest concentration was for the elements zinc, cadmium, calcium, sodium, lead, copper, Nickel, potassium and salinity concentrations and values (0.235, 0.0124, 720, 610.3, 0.417, 0.2358, 0.1812, 58.179,49) mg/l respectively, and Lowest concentration (0.021, 0.001, 128.8, 472.6, 0.21, 0.021, 0.0083, 44.1,42) mg/l respectively, as the elements zinc, lead, and copper are present In the spring, and the elements cadmium, calcium, and potassium in the autumn, and the elements sodium, nickel, and salinity in the summer. Conducting a canonical analysis (PCA) showed that the elements copper, calcium, sodium, and nickel were positively correlated with salinity, while salinity was correlated with nickel in the summer, and the elements potassium, sodium, and calcium during the autumn, while the rest of the elements were negatively correlated with salinity. The ready-made statistical program (SPSS) was used, to notable variations. When performing the cluster analysis, it was revealed that there were three cluster groups
