- Data starts 1st August 2005. All data since then has been processed using the POL tide/depth
model to provide water depth for the wave inversion.
- From 7th September 2007 onwards, a new utility was introduced by the manufacturers Helzel, to
give even more accurate positioning of the data on the sea surface.
- From March 2007 onwards, wave data for certain cells was no longer processed as the beam angle was
deamed too wide. Data for these cells therefore ceases after this date.

IMPORTANT. Since the data is recorded over 8mins 52 seconds and the time given in
the files is the start time, PLEASE ADD 266 SECONDS (4mins, 26secs) to supplied times to give the true data time.
Real-time data - 60 minute collection
The real-time data is collected and displayed automatically every hour, with up to a 30 minute
lag between completion of data collection and web display.
Real-time data will have gaps due to both operational problems and communication problems
and should therefore be used only as a guide to what is happening now. If data is needed
for scientific purposes then the 20 minute batch data time series data should be used.
Batch data - 20 minute collection
Batch data is collected manually monthly, so there is usually a lag in the latest time
processed.
The data is more complete than the real-time data.
