Data for: Lessons learned from the design and operation of a small-scale cross-flow tidal turbine

The Turbine Lander, a small-scale (1.19 m x 0.85 m) veritical-axis, cross-flow turbine was developed at the Applied Physics Laboratory at the University of Washington to generate modest amounts of power (e.g., 100 W average) from tidal currents. Following design and fabrication, the Turbine Lander was characterized in laboratory and controlled field testing before being deployed for 141 days in Sequim Bay, Washington. Cabled operations during the deployment enabled real-time data aquisition of variables related to system performance. In addition, environmental observations were sampled using an Adaptable Monitoring Package (Polagye at el., 2020).  \"Lessons learned from the design and operation of a small-scale cross-flow tidal turbine\" by Bassett et al. (2025) summarizes the efforts to characterize the system, assess its performance in situ, and offers lessons learned from the laboratory-to-field effort.

Description:

This file contains information about the various data files supporting Bassett et al. (2025) - \"Lessons learned from the design and operation of a small-scale cross-flow tidal turbine\". Each of the following sections, one of the directories or .mat files. Several plotting scripts (.m) files are available for use with individual .mat files (Version 5.0). Scripts make use of datetime variables and are therefore not capability with MATLAB versions released prior to MATLAB R2014b.
