马朱罗环礁约50公里的泻湖海岸正在遭受侵蚀，这是由人类活动引起的，包括骨料挖掘和建造堤道、人工渠道、垃圾填埋场和其他建筑。泻湖海岸的西长海岸输沙对西环礁泻湖海岸的稳定具有重要意义。西环礁泻湖海岸的侵蚀是由东环礁的开发引起的。海滩岩石的分布表明南部边缘以前存在连续的陆地。堤道没有引起泻湖海平面上升。不应在南部边缘开孔，因为这将导致严重的侵蚀。提出了改革泻湖海岸建设的建议。
About fifty kilometers of lagoon coast in Majuro Atoll is suffering erosion, which is induced by human activities including aggregate excavating and building causeways, artificial channels, landfill and other constructions. The west longshore sediment transportation on lagoon coast is significant for stability of lagoon shore of the west atoll. The lagoon coast erosion on the west atoll is induced by development on the east atoll. Distribution of beachrock demonstrates former existence of a continuous land on the south rim. The causeway has not caused sea level rising in lagoon. Openings on the south rim should not be made, as these will induce severe erosion. Reforming lagoon coastal constructions is proposed.
