Manly Hydraulics Laboratory (MHL) (part of the NSW Department of Planning, Industry and Environment (DPIE), which has assumed function of former NSW Office of Environment and Heritage (OEH)) operates a system of Waverider buoys off the NSW coastline. The buoys measure wave height and other wave statistics such as wave period on a continuous real-time basis, and are also capable of measuring wave direction (wave data accessible via related metadata record: Waverider buoys Observations - Australia - delayed (National Wave Archive) - https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/2807f3aa-4db0-4924-b64b-354ae8c10b58) and sea surface temperature (SST). The data is gathered by the Waverider system developed by the Dutch company, Datawell, namely thermistors that are mounted inside the hull of the buoys, at the base of the buoy about 0.5m below the water surface. The SST data is stored on the receiving station PC before routine transfer to Manly Hydraulics Laboratory via email.
