///1 core (132 cm long and 44 samples) and 50 bottom sediments samples were collected in the offshore area on the north side of the Huanghua Harbor, and grain size analysis was carried out. The results indicate that there are three types of bottom sediments, namely sandy silt, silt and clayey silt, in the area. Sandy silt is distributed in the subtidal zone on the north side of the harbor, silt mainly in the offshore area ‐2 m~‐5 m in water depth at Daxinpu and sampling site 13, and clayey silt in the other area. According to the vertical grain size distribution pattern of the sediments, the Hole HHG2 can be divided into four segments from bottom to top: 1) the segment with slight fluctuation of coarse-fine grains in 132~100.5 cm; 2) the segment slowly coarsening up in 100.5~56 cm; 3) the segment with rapidly coarse-fine fluctuation caused by episodic events in 56~16 cm; and 4) the segment rapidly coarsening up in 16~0 cm.
