adp: ADP (acoustic-doppler profiler) dataset

Description

This is a sampling of measurements made with an upward-pointing ADP (acoustic doppler current profiler) manufactured by Teledyne-RDI, as part of the St Lawrence Internal Wave Experiment (SLEIWEX).

Usage

data(adp)

source

This file came from the SLEIWEX-2008 experiment.
