尽管在过去的三十年里已经测量了太平洋-印度洋交换[印度尼西亚洋流（ITF）]，但该地区的微塑料测量非常有限。这项研究是对ITF通道深海区域微塑料垂直分布的初步调查。利用尼斯金水样从5至2450 m范围内的水柱中获得样品。共有924个微塑料颗粒，平均丰度为1.062 ± 0.646。在水柱中发现了N/L。研究结果表明，水温和水密度是影响微塑料浓度的最重要因素。这项研究将是第一份讨论微塑料在深海水柱中分布的报告，这对确定进入印度洋的印度尼西亚沃茨内微塑料的命运和运输具有重要意义。
Even though Pacific – Indian Ocean exchange [Indonesian Throughflow (ITF)] has been measured for the last three decades, the measurements of microplastic in the region is very limited. This study was the initial investigation of the vertical distribution of microplastic in the deep-sea areas across the ITF Pathway. Niskin water samples were utilized to obtain the samples from a water column in a range of 5 to 2450 m. A total of 924 microplastic particles with an average abundance of 1.062 ± 0.646. n/L were found in the water column. Our findings indicate that water temperature and water density are the most significant factors correlated to the microplastic concentration. This study will be the first report discussing the distribution of microplastics in the deep-sea water column that could be highly significant in determining the fate and transport of microplastic within Indonesian waters that exits into the Indian Ocean.
