Popis:	Field observations were carried out to investigate sedimentary characteristics at the estuarine area of Tama river, where a national project for future extension of Haneda international airport is undergoing.The survey includes sediment core samplings and acoustic sub-bottom profilings of the site.Based on the analysis of the core samples, spatial distribution of thickness of fluid mud layer has been obtained and it develops to the off shore from mouth of the river. Acoustic images have clearly shown the difference of the sedimentary structures between shallower monitoring point inside the river and offshore point with higher mud content.The images were evaluated by comparison with analysis data, such as water content, of bottom sediment samples.
