In June 2016, a cruise vessel was grounded in the Mormugao Port, resulting in unnoticed oil spill. The surface water and sediment samples were collected from the vicinity of the ship, and also an oil sample from the ship (OIL). These samples were subject to petroleum biomarker such as pentacyclic triterpenes (hopanes) and compound specific carbon isotopic (δC) analyses to assess the source of hydrocarbon pollution in the Mormugao Port. While no clear trend was observed in water samples, the bottom surface sediments did show an identical pattern of hopanes with the oil. The chemometric analyses of hopane Diagnostic Ratios (DRs) and δC ratios confirmed the ship oil as the source of oil pollution in sediments. Whereas the water is comparatively more dynamic than the sediment, the physical processes arising out of winds, waves, tides and currents might have dispersed the oil away from the grounded ship.
2016 年 6 月，一艘游轮在莫尔穆冈港搁浅，造成了未被注意到的石油泄漏。从船只附近采集了地表水和沉积物样本，还从船上采集了一个油样（OIL）。这些样本经过石油生物标志物（如五环三萜烷（藿烷）和化合物特定碳同位素（δC）分析，以评估莫尔穆冈港的碳氢化合物污染来源。虽然在水样中没有观察到明显的趋势，但底部表层沉积物确实显示出与油相同的藿烷模式。藿烷诊断比（DR）和δC 比的化学计量分析证实，船用油是沉积物中石油污染的来源。由于水比沉积物更具动态性，风、浪、潮和流引起的物理过程可能已经将油从搁浅的船只中分散开来。
