This is a core program in the Black Sea expedition. Honjo will collect and analyze annual (12 to 14 months) particulate flux samples applying high resolution sediment trap technology (at 15-day intervals) in the Black Sea. In addition, there will be a short-term deployment for 3 months at 2 depths using synchronized time-series traps during the spring bloom period with a sampling interval of less than one week. Simultaneously, extensive box core sampling at the trap site and along a W-E transect between the trap sites will establish the annual particulate flux over the last 5,000 years as annual paleoflux. This study will further be supported by a broad range of highly focused studies pertaining (1) to the source of the terrigenous, biogenic, and chemogenic particles, (2) to the transport mechanism of the particles, and (3) to the chemical and microbiological alterations of the particles in the anerobic water column and in the sediment.

这是黑海探险的核心计划。 Honjo 将收集和分析每年（12至14个月）的颗粒物 应用高分辨率沉积物捕获技术的通量样品 (at 15天的间隔）在黑海。 此外还将 在2个深度短期部署3个月， 春暖花开期同步时序诱捕 采样间隔不超过一周。 与此同时， 在圈闭现场和沿着W-E 在陷阱地点之间的样带将建立每年的 过去5,000年的颗粒通量作为年度古通量。 这项研究将进一步得到广泛的高度支持， 重点研究（1）陆源物质来源， 生物和化学颗粒，（2）运输 颗粒的机制，以及（3）化学和 厌氧环境中颗粒物的微生物变化 水柱和沉积物中。
