Scripts from project git repo + tutorial slide deck generated for the TEAMER RFTS 1 (request for technical support) collaborative project between Ocean Motion Technologies, Inc. and Sandia National Laboratories + National Renewable Energy Laboratory. The project simulates an adaptive wave energy converter through CAD, FEA, and analysis code.

The following information and metadata applies to both the Phase I (Hydrodynamics) and Phase II (Full System Power Take-Off) zip folders which contain testing data from the OSU (Oregon State University) O.H. Hinsdale Wave Research Laboratory, from both OSU and the University of Hawaii at Manoa (UH). See zip folders provided further below in the downloads section. For experimental data of the full system, including PTO, see Phase II dataset. There are two main directories in each Phases's zip folder: "OSU_data" and "UH_data". The "OSU_data" directory contains data collected from their DAQ (data acquisition system), which includes all wave gauge observations, as well as body motions derived from their Qualisys motion tracking system. The organization of the directory follows OSU's convention. Detailed information on the instrument setup can be found under "OSU_data/docs/setup/instm_locations". The experiments conducted are documented in the "OSU_data/docs/daq_logs", which provides the trial number to the corresponding data located under "OSU_data/data" in several formats (e.g., ".mat" and ".txt"). Inside the trial directory, data is provided for each of the instruments defined in "OSU_data/docs/setup/instm_locations". The "UH_data" directory contains data collected from their DAQ. The data is stored in a ".tdms" file format. There are free plug-ins for Microsoft Excel and MathWorks MATLAB to read the ".tdms" format. Below are a few links providing methods to read in the data, but a Google search should identify alternatives sources if these no longer exist (valid as of January 2024): Excel: http://www.ni.com/example/27944/en/ MATLAB: https://www.mathworks.com/matlabcentral/fileexchange/30023-tdms-reader The Excel plugin is recommend to get a quick overview of the data. The UH data is organized by directory name, in which the sub-directories for each experiment contains a directory whose name defines the wave height and period for the experimental data within. For example, a directory name "H02_T0275" corresponds to an experiment with wave height 0.1m and a period of 2.75s. For random wave data, the gamma value is also included in the directory name. For example, a directory name "H02_T0225_G18" corresponds to an experiment with a significant wave height of 0.2m, a peak period of 2.25s, and a gamma value of 1.8, with each spectra being a TMA spectrum. For the free decay experiments, the directory name is defined by the initial angular displacement. For example, a directory name "ang05_run01" corresponds to an experiment with an initial angular displacement of 5 degrees. There is a dataset in the UH data for each corresponding experiment defined in the OSU DAQ logs. The ".tdms" data is output from the DAQ at fixed intervals. Therefore, if multiple files are contained within the folder, the data will need to be stitched together. Within the UH dataset, there are two input channels from the OSU DAQ providing a random square wave signal for time synchronization ("ENV-WHT-0010") and a high/low signal ("ENV-WHT-0012") to identify when the wave maker is active (+5V). The UH data is logged as a collection of channel outputs. Channels not in use for the OSU testing (either Phase I or Phase II) are marked "nan" below. If the sensor is disconnected, it will record noise throughout the experiment. Below are the channel definitions in terms of what they measure: GPS Time = time CYL-POS-0001 = position between flap and fixed reference CYL-LCA-0001 = force between flap and hydraulic cylinder REC-LPT-0001 = nan REC-HPT-0001 = nan REC-HPT-0002 = nan REC-HPT-0003 = nan HHT-HPT-0001 = pressure at exhaust ("head" only) REC-FQC-0001 = nan REC-FQC-0002 = nan HHT-FQC-0001 = flow at exhaust ("head" only) ENV-WHT-0001 = nan ENV-WHT-0002 = nan ENV-WHT-0003 = nan ENV-WHT-0010 = random signal from OSU DAQ ENV-WHT-0012 = high/low signal from OSU DAQ Also included is a calibration curve to convert the string pot data to flap pitch motion. There are two

This data submission contains raw and near-real-time updated data from FLOATr (Fixed Location Ocean and Atmosphere Tracking) buoys and Sofar Spotter wave buoys at sites in the PacWave open-ocean testing facility operated by Oregon State University, located off the coast of Newport, Oregon. There are two sites located at PacWave, aptly named PacWave North (PWN) and PacWave South (PWS). PWN is an autonomous test site located 2 nm offshore, has a water depth of 45-55 m, and is between 44.68 & 44.70 degrees North and 124.12 & 124.15 degrees West. PWS is a grid-connected test site located 6 nm offshore, has a water depth of 65-78 m, and is between 44.55 & 44.58 degrees North and 124.21 & 124.24 degrees West. The FLOATr buoys provide meteorological measurements of wind speed and direction, air temperature and pressure, shortwave radiation (light). An onboard CTD (conductivity-temperature-depth) sensor provides measurements of water temperature, salinity, and dissolved oxygen. Down-looking ADCPs installed on the FLOATr buoys provide observations of water velocity. The wave buoys provide measurements of standard and directional wave statistics as well as additional metocean variables, depending on the firmware version installed. Raw data are provided in the original CSV file format, and processed data are provided in netCDF4 format. Processed data are provided in netCDF4 format based on Integrated Ocean Observing System (IOOS) standards. Note, minimal quality control has been conducted on these data. Raw data from the FLOATr buoys are stored in CSV files with the following filenames: - ADCP.dat (subsampling of ADCP binary data - Teledyne Sentinel Workhorse 300khz) - Airmar_buffer.dat (Airmar WX200 instrument serial data buffer) - gga.dat (gps Degree & Decimal Minutes) - hdg.dat (magnetic heading, deviation, variation) - hdt.dat (heading true) - mda.dat (meteorological composite) - Met.dat (multiple data values from various sources (instruments, nmea strings) into a single data table) - best for quick data checks - mwv_r.dat (calculated mean wind velocity_relative) - mwv_t.dat (calculated mean wind velocity_true) - Ocean.dat (CTD data - Seabird SBE16, temp, conductivity/salinity, 02) - zda.dat - (time and date) Raw data from the FLOATr ADCPs and CTDs are made available in their native binary format. Raw data from the Spotter buoys is stored in CSV files with the following filenames: - BARO.csv (barometric pressure) - FLT.csv (processed buoy displacement: surge, sway, and heave) - GMN.csv (raw GPS parameters) - HDR.csv (raw buoy position) - HTU.csv (air temperature and humidity) - LOC.csv (GPS latitude and longitude) - PWR.csv (power data) - SPC.csv (buoy-derived auto- and cross-spectra * note frequency vector is missing) - SST.csv (sea surface temperature) - *.log (various log files)
