(Table 1) Frequency of wind direction reportings and duration of wave action in Mittelgrund, Eckernfoerder Bay, Germany

A detailed survey of the Mittelgrund in Eckernförde Bay shows slope breaks at 10-12 m and 15-16 m water depth. They are thought to be mainly the result of marine abrasion. Utilizing records from the Edgerton mud-penetrator, a map of holocene sediment thickness has been drawn. From the pattern of bottom echos 4 types of stratification can be recognized. An interpretation of them is attempted, as they are supposed to serve as models for other transgression contacts.

对埃克恩弗尔德湾（Eckernförde Bay）内米特尔格兰德（Mittelgrund）区域的精细化勘测显示，该区域存在两处水深分别为10~12米与15~16米的坡折带（slope break）。此类坡折带被认为主要由海蚀作用（marine abrasion）塑造形成。研究人员借助埃德杰顿泥浆穿透器（Edgerton mud-penetrator）的实测记录，绘制了全新世（Holocene）沉积物厚度分布图。基于水底回波（bottom echos）的形态特征，可识别出4种层理构造（stratification）。研究人员尝试对这四类层理构造进行解译，因其可作为其他海侵接触带（transgression contacts）的类比参考模型。
