Megaripple in the Surf-Zone

PIs将研究大规模的海底形态，重点研究高度高达50厘米，长度在1到10米之间的巨型波纹，这是人们知之甚少的特征。到目前为止，第四纪地层只在北卡罗莱纳海岸进行过研究，通过参与荷兰和英国计划进行的3D实验，这项研究将为我们提供一个机会，大大增加我们对小规模形态的了解。荷兰科学家已经建造了仪器，将在荷兰和英国的海滩上部署。pi将在荷兰仪器上安装声学高度计和侧扫声纳，以测量河床特征的小尺度形态。

GallagherAbstractThe PIs will study large-scale seafloor morphology focusing on the poorly understood feature known as megaripples with heights of up to 50 cm and length between 1 and 10 m. Quaternary bedforms have so far only been studied along the North Carolina coast and the study will provide an opportunity to greatly increase our knowledge regarding small scale morphology by taking part in a 3D experiment planned in the Netherlands and the U.K. The Dutch scientists have built instrumentation that will be deployed on the beaches in Holland and England. The PIs will mount acoustic altimeters and side-scan sonar on the Dutch instruments to measure small-scale morphology of the bedform features.
