9811149DeaneIn this project, the PI will study the creation and evolution of bubbles inside oceanic breaking waves on length scales of the order of millimeters to centimeters, and on millisecond time scales. An optical imaging instrument, based on a successful laboratory instrument will be developed and deployed in the surf zone, along with an underwater video camera, a pressure sensor, and a hydrophone. In the images thus created, air-water boundaries appear as bright lines, larger bubbles appear as bright rings, and smaller bubbles appear as bright dots. Patterns in individual images will give a static view of bubble formation, while the differences between successive images will give a dynamical view of these processes.

9811149 deanein这个项目，PI将研究海洋破裂波中的气泡在毫米至厘米的长度尺度上以及以毫秒的时间尺度上的长度。 基于成功的实验室仪器的光学成像仪器将在冲浪区开发并部署，以及水下摄像机，压力传感器和水文。 在如此创建的图像中，空气水边界显示为明亮的线条，较大的气泡显示为明亮的环，较小的气泡出现为明亮的点。单个图像中的模式将对气泡形成产生静态视图，而连续图像之间的差异将使这些过程具有动态视图。
