A seafloor sediment dataset of 42 samples has been collected from the coastal and nearshore areas of the northern Bay of Bengal, which is situated in the southern part of the eastern coastal zone of Bangladesh. From February 2018 to March 2019, Van Veen grab samplers were employed to gather samples at a depth of 4 m and 23 m. The unconsolidated bottom surface has been sampled, taking bathymetry and fishing boat accessibility into account. Using the dry sieving technique, grain size distribution analysis was performed on the obtained sediments. The retrieved dataset was measured to identify seafloor sediment grain size distribution and determine the sediment dynamics. This data can be used to delineate sediment characteristics, depositional processes, and the environment.
已从孟加拉湾北部沿海和近岸地区收集了一个包含42个样本的海底沉积物数据集，该地区位于孟加拉国东部沿海地带的南部。2018年2月至2019年3月期间，使用范维恩抓斗采样器在4米和23米深度采集样本。考虑到测深和渔船可达性，对未固结的海底表面进行了采样。利用干筛技术，对所获得的沉积物进行了粒度分布分析。对检索到的数据集进行测量，以确定海底沉积物粒度分布并确定沉积动力学。这些数据可用于描绘沉积物特征、沉积过程和环境。
