Sample Data Files#
Three sample data files are provided to be used with OCEANLYZ:
The 3rd file is named “waterlevel_5burst.csv”, and contains 5 bursts of synthetic water level data generated from the JONSWAP spectrum in a single column.
The 1st file is named “waterpressure_1burst.csv”, and contains 1 burst of water pressure data recorded with a pressure sensor in a single column.
The 2nd file is named “waterpressure_5burst.csv”, and contains 5 bursts of water pressure data recorded with a pressure sensor in a single column.
Data in either of these files can be used as input data for OCEANLYZ.
