Coastal and nearshore sediment data along the eastern coastal zone of Bangladesh of the northern Bay of Bengal

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.
