This dataset contains data recordings generated during Year 3 of a DOE-funded project focused on the co-design of marine energy converters and autonomous underwater vehicle (AUV) docking and recharging systems. Data was collected during experimental testing at the O.H. Hinsdale Wave Research Laboratory and support foundational research aimed at advancing coupled Wave Energy Converter (WEC)-AUV systems for marine energy applications. This release builds on and supplements data provided in the previously submitted Year 3 project software and data submission from this project, linked below. This dataset includes measurements of wave elevation, water pressure, dock motion, load on a dock, and load on a fixed Autonomous Underwater Vehicles (AUV). Additionally, a testing log is provided including testing logs and summary of the five conditions tested: -(1) regular and random waves -(2) waves with dock motions -(3) multi-sine waves -(4) multi-sine dock motions -(5) multi-sine waves with dock motions.
