Lidar observation of a strongly nonlinear internal wave train in the Gulf of Alaska

Abstract

This paper demonstrates the observation of what appears to be a partially developed solitary internal wave group using an airborne lidar over the Gulf of Alaska. The probable generation mechanism is the interaction of the tide with the continental shelf 130 km away. Detection by lidar was possible because of a planktonic layer associated with a shallow pycnocline.
