Since 2013, there has been an increase (>23%) in naval traffic using maritime routes and ports on the coastal fringe of Santa Marta, Colombia. Of major concern, and described by several studies, is the relationship between maritime traffic and coastal contamination. This study proposed a maritime traffic indicator considering the simultaneous effects of several relevant measurements of water quality parameters to estimate the impact of naval activity. The approach involved developing a model including the number of vessels, hull length, and permanence time in berths. In addition, water quality variables, considering climatic seasons, were used to verify association with maritime traffic and touristic activities. The high concentrations of total coliforms (TC) and dissolved/dispersed petroleum hydrocarbons in chrysene equivalents (DDPH) reported by the International Marina of Santa Marta (SM) were affected by the local anthropic activities, including tourism, naval traffic, and urban wastewater discharges. Moreover, our results suggest the occurrence of multiple chemical impacts within Tayrona National Natural Park (PNNT) affecting conservation goals. The estimation of the maritime traffic indicator proposed in this study may be an easy and more complete tool for future studies evaluating the impact of naval activities on environmental quality.

海上交通对哥伦比亚圣玛尔塔水质参数的影响

自2013年以来，使用海上路线和哥伦比亚圣塔玛尔塔沿海边缘的港口的海上交通量增加了（> 23％）。几项研究描述的主要问题是海上交通与沿海污染之间的关系。这项研究提出了一种海上交通指标，该指标考虑了几种相关水质参数测量值的同时影响，以估计海军活动的影响。该方法涉及开发一个模型，其中包括船只的数量，船体长度和泊位的持续时间。此外，考虑到气候季节，使用水质变量来验证与海上交通和旅游活动的关联。圣玛尔塔国际游艇码头（SM）报告的高总大肠菌群（TC）和溶解/分散的石油碳氢化合物（DDPH）中的苯当量（SM）受当地人类活动的影响，包括旅游业，海军交通和城市废水排放。此外，我们的结果表明，在塔罗纳国家自然公园（PNNT）内发生了多种化学影响，影响了保护目标。这项研究中提出的海上交通指标的估计可能是将来评估海军活动对环境质量的影响的一种简单而完整的工具。我们的结果表明，在塔罗纳国家自然公园（PNNT）内发生了多种化学影响，影响了保护目标。这项研究中提出的海上交通指标的估计可能是将来评估海军活动对环境质量的影响的一种简单而完整的工具。我们的结果表明，在塔罗纳国家自然公园（PNNT）内发生了多种化学影响，影响了保护目标。这项研究中提出的海上交通指标的估计可能是将来评估海军活动对环境质量的影响的一种简单而完整的工具。
