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.  The data included here, which is
summarized in detail below, are the outputs of key labratory and
vessel-based characterization efforts, inflow conditions during the
deployment, power generation by the Turbine Lander, and images of
biofouling and optical conditions observed during the deployment. Detailed
descriptions of the variables and example plotting scripts for working
with the .mat files are provided.
