Note that these are real-time data and are not quality-controlled. Long-range graphs are plotted from a randomised subsample of half-hourly data.
|Wave buoy location||50° 44.06' N 000° 29.64' W|
|Approximate water depth||9.9 m CD|
|Approximate spring tidal range||6.1 m|
|Storm alert threshold||3.34 m|
Wave parameters are recorded using a Datawell Directional WaveRider Mk III buoy. The buoy was deployed on 15 July 2003 from the MV Wessex Explorer, at which time the magnetic declination at the site was 2.7° west, changing by 0.14° east per year.
|20/06/2020||Electrical works at the shore station resulted in a temporary power outage.|
Due to recabling works takin gplace at the shore station, power has temporarily been cut.
We are working at setting up an alternative receiver station for the time being.
|16/03/2020||The buoy was recovered and a replacement buoy deployed.|
|05/03/2020||We have stopped receiving data from the buoy.|
|01/05/2019||Scheduled service. Temperature measurements should return to normal.|
|30/08/2018||The site is being used for beta testing of a new piece of equipment. The measurements provided on the Realtime Data pages are incorrect. Works to provide accurate realtime data are underway.|
||Replacement buoy deployed|
|21/03/2016||A noticeable change in the direction and spread readings has been observed since the last scheduled service was carried out when the buoy was swapped. The data are considered suspect and the buoy will be swapped out at the earliest opportunity. All other data are plausible.|
|03/04/2014||The intermittent data over the last two days has been due to issues with the computer at the shore station.|
|01/02/2013||Buoy came adrift from its mooring around 0300 but has now been recovered and will be redeployed asap|
|11/12/2011||The buoy has now been re-deployed following its becoming adrift several days ago, since when rough seas had prevented re-deployment|
|28/07/2009||Scheduled service, new GPS antenna and HF antenna|
|20/02/2009||The buoy was been taken into harbour for a battery change and re-deployed on station later that day|
|21/07/2008||Data not arriving at website|
|28/04/2008||The buoy came off its mooring at 0700 on Sunday 27 April. The buoy has been recovered and is being checked|
|05/03/2008||The buoy came adrift at 2330 on 03 March. A recovery boat was deployed and the buoy was picked up at 1400 today. There is no evidence of damage therefore the buoy will be re-deployed as soon as possible|
|29/11/2007||Deployment of a replacement DWR; the previous buoy came adrift and was sent for a re-paint on recovery|
|19/11/2007||The buoy has been recovered from the beach and has been redeployed|
|18/11/2007||The wave buoy appears to have been hit by a vessel and has become detached from its mooring|
|25/11/2005||The sea surface temperature readings appear to be incorrect. The thermistor will be checked on the next service visit|
|18/11/2005||All power will be turned off at Arun DC offices this weekend and therefore no data can be received from the waverider. The data are stored on the buoy and will be retrieved during the next service visit|
|18/05/2005||The buoy was recovered at 1630 yesterday, but has incurred some damage|
|17/05/2005||The buoy moved off station at about 0700 this morning, recovery efforts are underway|
|25/04/2005||The buoy has been serviced and calibrated by Datawell|
|20/12/2004||The radio signal became corrupted due, possibly, to atmospheric conditions. The fault is being investigated|
|13/05/2004||W@ves21 software has been updated and all wave parameters are being properly processed|
|29/03/2004||The RXD receiver required re-tuning|
|19/03/2004||The W@ves21 software is still not processing the incoming data properly. As a short-term fix, the values for Hs and Tm are being replaced on the website by H1/3 and T1/3, which are very similar approximations of Hs and Tm, and which are being properly processed by W@ves21.|
