Port Blair is the capital city of Andaman & Nicobar Islands, the union territory of India. More than 50% of the population of these islands lives around Port Blair Bay. Therefore the anthropogenic effects in the bay water were studied for monitoring purpose from seven stations. Physico-chemical parameters of seawater were analyzed in samples collected once in every 3 months for 2 years from seven sampling stations located in Port Blair Bay, South Andaman Island to evaluate the spatial and tidal variation. Cluster analysis and factor analysis were applied to the experimental data in an attempt to understand the sources of variation of physico-chemical parameters. In cluster analysis, the stations Junglighat Bay and Phoenix Bay having high anthropogenic influence formed a separate group. The factors obtained from factor analysis indicated that the parameters responsible for physico-chemical variations are mainly related to land run-off, sewage outfall and tidal flow.
布莱尔港是印度安得拉邦和尼科巴群岛的首府。这些岛屿超过 50%的人口居住在布莱尔港湾周围。因此，为了监测目的，对湾内的海水进行了人为影响研究。从南安达曼岛的布莱尔港湾的 7 个采样点采集海水样本，每 3 个月采集一次，持续 2 年，以评估空间和潮汐变化。对实验数据进行了聚类分析和因子分析，试图了解理化参数变化的来源。在聚类分析中，受人为影响较大的荣格尔哈特湾和凤凰湾两个站点形成了一个单独的组。因子分析得到的因子表明，导致理化变化的参数主要与陆源径流、污水排放口和潮流有关。
