TigerRAY Moored Deployment Data

Published by University of Washington Applied Physics Lab | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-06-03T18:30:46Z
This respiratory contains TigerRAY moored deployment data for each day in which data was collected between January 10, 2024 and March 3, 2024. For sensors on and inside TigerRAY, there is one .mat file for each day in which TigerRAY operated and collected data. These files are labeled as: "DDMMMYYYY_TigerRAYdata.mat" corresponding to the date collected. These .mat files contain a single variable, data, formatted into: - time stamps and load cell readings from the heave plate - time stamps and data from the two heave plate mounted pressure sensors - structure containing data from the heave plate mounted IMU - data collected by the central data acquisition system in the nacelle - timestamps and data from encoder 1 - timestamps and data from encoder 2 - structure containing data from the nacelle mounted IMU - data from the satellite compass mounted to the mast of the nacelle For SWIFT data, there is one data file that contains all reprocessed SWIFT data for the entire deployment. This repository contains three structures, named SWIFT22_rp, SWIFT23_rp, and SWIFT24_rp. Reprocessing of the data was done to remove frequency components in the wave spectra with frequencies < 0.2 Hz. The remaining energy is distributed between 0.2 Hz and 1 Hz. New significant wave height, peak period, energy period, and peak direction were then calculated from these trimmed energy spectra. See attached data guide for a complete summary of data included in this submission, description of the data products (TigerRAY and SWIFT data), and deployment setup information and figures.
