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.

曼利水力学实验室(MHL)是新南威尔士州环境与遗产办公室(OEH)的一部分(职能现由新南威尔士州规划、工业和环境部(DPIE)承担)，在新南威尔士州海岸线外运行一个波浪浮标系统。浮标连续实时测量波高和其他波统计数据，如波周期。一些浮标还能够测量波浪方向和海面温度(可在另一个集合中发现：曼利水力实验室波浪浮标-海表面温度数据-https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/81c5f192-d4af-4dfe-a660-af15ae46a22a).该元数据记录是描述MHL Wiverider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一次部署，并提供了指向可下载数据的链接。数据是由荷兰公司Datawell开发的Wiverider系统收集的。Wiverider系统使用安装在一个松散的系绳浮标(直径为0.7或0.9米)中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，然后将这样获得的位移信号传输到岸站，在那里对其进行处理以提供波浪数据统计。波浪数据存储在接收站PC上，然后通过电子邮件例行传输到曼利水力实验室。具有波浪方向能力的Wiverider浮标利用升降俯仰滚动传感器、两个固定的X和Y加速度计和一个三轴磁通门罗盘来测量垂直和水平运动。车载处理器将浮标运动转换为三个垂直的(垂直的、南北的、东西的)转换信号，并传输到岸上站。<BR/> 最初由该元数据记录表示的数据已重新格式化，现在成为国家波浪档案馆的一部分，并可从该集合中访问-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)。
