deployment This page provides an overview of the benchmark dataset for instruments that measure velocity profiles e.g., acoustic-Doppler current profilers from diverse suppliers and models.

Datasets available

Selection and preparation of benchmark datasets are a work in progress! These benchmark datasets will cover a range of marine environments, background stratification, and flow fields. They are temporarily in this folder and will eventually be housed at the BODC center with a DOI.
