Particle fluxes obtained from sediment trap experiments in the northern Indian Ocean

The sediment trap experiment started in 1986 and was expanded into the Bay of Bengal only one year later in 1987. The fieldwork ended at around 1998. In 2007 and 2008, we tried to reinitiate a sediment trap program in the Arabian Sea, although this could not be followed up due to piracy, which became an issue in the region at that time. The sediment trap sites in the northern and central Bay of Bengal were shifted slightly southward in some years, whereby the stations NBBT and CBBT were spilt into northern (NBBT-N, CBBT-N) and southern sites (NBBT-S, CBBT-S). Between 2001 and 2004 additional sediment trap experiments were carried out in the upwelling system off South Java.该沉积物捕获器（sediment trap）实验于1986年启动，1987年即一年后将研究范围扩展至孟加拉湾。野外作业于1998年左右收尾。2007至2008年间，团队尝试在阿拉伯海重启沉积物捕获器项目，但因该区域彼时出现海盗问题，后续工作未能持续推进。孟加拉湾北部与中部的沉积物捕获器站位在部分年份略有南移，原站位NBBT与CBBT由此被拆分为北部子站位（NBBT-N、CBBT-N）与南部子站位（NBBT-S、CBBT-S）。2001至2004年间，团队在南爪哇外海的上升流系统中额外开展了沉积物捕获器实验。
