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.

Gallagher 摘要 PI 将研究大规模海底形态，重点研究人们知之甚少的特征，即高度可达 50 厘米、长度在 1 至 10 m 之间的巨型波纹。 迄今为止，仅对北卡罗来纳州海岸的第四纪地床形态进行了研究，这项研究将提供一个机会，通过参与计划在荷兰和英国进行的 3D 实验，大大增加我们对小尺度形态的了解。荷兰科学家已经建造了仪器，将部署在荷兰和英国的海滩上。 PI 将在荷兰仪器上安装声学高度计和侧扫声纳，以测量地床特征的小尺度形态。
