Email: liuf53@mail.sysu.edu.cn (F Liu) Brief view: Hydrodynamics, suspended sediment concentration, and sediment particle size distribution were measured via four cruise shipboard in the mouth bar zone of the ME during the dry season of 2020.

Eighteen gauging stations covering the mouth bar zone of the ME were observed during both the neap tide (26 October 2020) and spring tide (1 November 2020). The data from gauging stations #16, #17, and #18 during ebb and ebb-flood periods during the neap tide were the same. This directory contains the following datasets: -data_current_velocity.xlsx: station number, time, longitudinal, latitude, x, y, depth observed from ADCP, depth of the last characteristic layer in the water column (depth_last_cell, m), depth of the first characteristic layer in the water column (depth_first_cell, m), and current velocity (cm/s) and direction (°) of six characteristic layers during spring and neap tides. -data_salinity_turbidity_SSC.xlsx: station number, time, longitudinal, latitude, x, y, depth observed from ADCP, depth observed from OBS (depth_OBS_H), turbidity (ntu), salinity (psu), and suspended sediment concentration (SSC, mg/L) during spring and neap tides. -data_particle_size_distribution.xlsx: station number, mean size (μm), suspended sediment size distribution of three characteristic layers , and bed sediment size distribution during spring and neap tides.
