1914年11月和1916年2月至3月，分别表明，该杂志的读者可能有兴趣简要回顾以前对该主题的某些贡献，特别是因为这两位作者提出的大多数问题已经占据了早期研究者的注意力。关于波浪作用的研究，我最近有机会查阅了一些关于涟漪的报告，并在下面的段落中提供了一些Kindle或Udden没有提到的文章的摘要。没有人试图编纂一个完整的参考书目的主题，但参考了大多数更重要的论文，已经引起了作者的注意。沙和更细的碎片在平行的山脊和槽的积累有点像水波的形式，虽然不是在所有的起源或形成方法，很久以前被认为是一个正常的产品波和电流的行动。在各种名称下，如”电流痕迹"、”波痕“、”涟漪漂移"、”电流漂移”和”摩擦痕迹”，现在通常被称为涟漪痕迹的现象被反复描述。虽然在桑迪上并不少见，但在潮滩和浅河口、湖泊和池塘的宽阔底部上，涟漪可能更为发育。在近海区较深的海底，它们也并非不存在，在那里，它们的出现深度超过600英尺。落潮露出的涟漪痕迹，
November, 1914, and February-March, 1916, respectively, suggest that readers of the Journal might be interested in a brief review of certain previous contributions to the subject, particularly since most of the questions raised by these two writers have occupied the attention of earlier investigators. In connection with a study of wave action, I have recently had occasion to consult a number of reports on ripple marks, and offer in the following paragraphs a synopsis of some essays not mentioned by Kindle or Udden. No attempt has been made to compile a complete bibliography of the subject, but reference is made to most of the more important papers which have come to the writer's attention.The accumulation of sand and finer debris in parallel ridges and troughs somewhat resembling water waves in form, though not at all in origin or in method of formation, was long ago recognized as a normal product of wave and current action. Under various names, such as" current mark,"" wave mark,"" ripple drift,"" current drift," and" friction markings," the phenomenon now generally known as ripple mark has repeatedly been described. Although not infrequently found on sandy beaches, ripple marks are perhaps better developed on tidal flats and over the broad bottoms of shallow estuaries, lakes, and ponds. They are not unknown on the deeper sea floor of the off-shore zone, where their occurrence to a depth of over 6oo feet has been demonstrated. Ripple marks which are exposed by the falling tide may be
