| Abstract | ||
| Considerable numbers of physical, chemical and bacteriological parameters were measured at seven stations in Shatt Al-Arab and North- west Arabian gulf during the period extended from winter 1994 to autumn 1995. The observed densities of oil- degrading bacteria were comparable to those reported for the same region. In general higher densities were observed in summer, while the lower densities were recorded in autumn. Statistical treatments of the monitored parameters demonstrated the following: 1. Stations 4,6 and 7 revealed a different trend in their distribution functions of the measured environmental parameters varied significantly of the situations of other stations. 2. Summer season showed dissimilar mode of variations dynamic, different largely, of the rest seasons, while winter and autumn were coordinated- approximately, in the same patterns of responsibility and distribution functions. 3. Same groups of environment parameters were marked in highly percentages of representation in the principal components reflecting specific signification effects of these parameters on the studied circumstances and occurred fluctuations. | ||
