Abstract
We describe the design, implementation, and deployment of a laser slope gauge developed at the Woods Hole Oceanographic Institution for the purpose of studying the propagation characteristics of capillary ripples, and how currents and natural slicks on the ocean surface modify ripple spectra. The laser slope gauge constitutes a nondisruptive optical technique for determining the slope spectrum for a range of waves with wavelengths between 2 mm and 20 cm using both spatial and temporal information. Operation of the sensor and data acquisition system is discussed and a sample data record collected in the Gulf Stream off Cape Hatteras, North Carolina is interpreted and analyzed.
