Can you use the Signature or other types of high-resolution ADCP modes to investigate small-scale motion? Will a field experiment provide the type of the data in which you are interested? In this webinar, we will introduce some of the basic techniques that are available for researchers and engineers who are interested in describing turbulent phenomena. This will be a non-mathematical introduction intended for anybody with an interest in the subject but not necessarily the mathematical background to delve into the full calculations.
