Manly Hydraulics Laboratory (MHL) part of the NSW Office of Environment and Heritage (OEH) (function now assumed by NSW Department of Planning, Industry and Environment (DPIE)) 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. Some of the buoys are also capable of measuring wave direction and sea surface temperature (discoverable in a separate collection: Manly Hydraulics Laboratory Waverider buoys - Sea surface temperature data - https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/81c5f192-d4af-4dfe-a660-af15ae46a22a). This metadata record is a parent record describing the MHL Waverider system as a whole. The child metadata records describe each deployment of the buoy in more detail with links to downloadable data. The data is gathered by the Waverider system developed by the Dutch company, Datawell. The Waverider system uses an accelerometer mounted in a loose tethered buoy (0.7 or 0.9m in diameter) to measure the vertical accelerations of the buoy as it moves with the water surface. The accelerations are integrated twice within the buoy and the displacement signal so obtained is then transmitted to a shore station where it is processed to provide wave data statistics. The wave data is stored on the receiving station PC before routine transfer to Manly Hydraulics Laboratory via email. The wave direction capable Waverider buoys utilise a heave-pitch-roll sensor, two fixed X and Y accelerometers and a three axis fluxgate compass to measure both vertical and horizontal motion. An on-board processor converts the buoy motion to three orthogonal (vertical, north-south, east-west) translation signals that are transmitted to the shore station. <br /> The data originally represented by this metadata record has been reformatted and now forms part of the National Wave Archive, and is accessible from that collection - https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/2807f3aa-4db0-4924-b64b-354ae8c10b58. The original data has been archived (contact IMOS for access).

Manly Hydraulics Laboratory（MHL）隶属于NSW Office of Environment and Heritage（OEH）（现由NSW Department of Planning，Industry and Environment（DPIE）承担），在NSW海岸线附近运营乘波号浮标系统。浮标连续实时测量波高和其他波浪统计数据，如波浪周期。一些浮标还能够测量波浪方向和海面温度（可在单独的集合中列出：Manly Hydraulics Laboratory Waverider buoys - Sea surface temperature data - https：//catalogue-imos.aodn.org.Au：443/geonetwork/srv/API/records/81 c5 f192-d4 af-4dfe-a660-af 15 ae 46 a22 a）。此元数据记录是描述MHL乘波号系统整体的父记录。子元数据记录更详细地描述了浮标的每次部署，并提供了可下载数据的链接。这些数据是由荷兰公司Datawell开发的Waverider系统收集的。乘波号系统使用安装在一个松散系留浮标（直径为0.7或0.9米）上的加速度计来测量浮标随水面移动时的垂直加速度。在浮标内对加速度进行两次积分，然后将如此获得的位移信号发送到海岸站，在那里处理该信号以提供波浪数据统计。在通过电子邮件向曼利液压实验室进行常规传输之前，波浪数据存储在接收站PC上。波浪方向的乘波浮标利用一个垂荡-俯仰-横摇传感器、两个固定的X和Y加速度计以及一个三轴磁通门罗盘来测量垂直和水平运动。机载处理器将浮标运动转换为三个正交（垂直、南北、东西）平移信号，并将其发送到海岸站。<br /> 最初由该元数据记录表示的数据已被重新格式化，现在构成国家波浪档案的一部分，可以从该集合访问-https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/2807f3aa-4db0-4924-b64b-354ae8c10b58。原始数据已存档（联系IMOS获取）。
