U.S. Naval Research Laboratory (NRL) researchers from the Ocean and Atmospheric Science and Technology Directorate and the Scientific Development Squadron (VXS) 1’s UV-18 Twin Otter conducted airborne research last month in Homer, Alaska.
NRL’s lidar system consists of a self-contained unit installed in a weatherproof enclosure, designed to be mounted on the Twin Otter’s research compartment with the laser pointed down into the water.
The team’s objective was to measure bubbles using lidar, a laser system for measuring ocean properties. Improved understanding of bubble fields has many applications, including radiance, surface properties, and characterization of the ocean’s surface.
Quantifying the oceanic whitecaps and subsurface bubbles is important to the Navy’s oceanographic models to characterize the long-term evolution of the ocean environment because bubbles are the primary way the atmosphere and oceans exchange heat, momentum, and gas.
