DOT Acoustic Wave and Current Deployments

This point feature class contains the locations of AWAC deployments across the state of Western Australia. Historic Tide and Wave data is held by DOT from Wyndham to Esperance. Tide; AWAC; Wave; Pressure and Current data currently available at the Department of Transport, Fremantle. This data can be ordered at the following link:http://www.transport.wa.gov.au/imarine/historical-tide-and-wave-data.aspWave data supplied is obtained by post-processing raw data from Datawell Wave rider. buoys. Wave statistics are produced by spectral analysis of raw elevations. The statistics supplied are the significant wave height (Hs) in metres, Peak Period (Tp) in seconds, Mean Period (T1) in seconds. These are supplied for the total wave as well as the separated sea and swell components. The sea:swell split is 8s.Directional data additionally has the direction at Tp of the sea and swell components. Directions are given in degrees from magnetic north. The directions as are calculated by the wave buoy at the Tp computed by the post-processing software.本点要素类包含西澳大利亚州全域内AWAC（声学波浪与海流剖面仪）布放点位的位置信息。西澳大利亚州交通部（DOT）持有从温德姆到埃斯佩兰斯区间的历史潮汐与海浪数据。弗里曼特尔交通部当前可提供潮汐、AWAC、海浪、压强及海流相关数据。可通过以下链接订购此类数据：http://www.transport.wa.gov.au/imarine/historical-tide-and-wave-data.asp。所提供的海浪数据源自对Datawell波浪浮标原始数据的后处理流程。海浪统计参数通过对原始海面高程数据的频谱分析生成，具体包括以米为单位的有效波高（Hs）、以秒为单位的峰值周期（Tp）与平均周期（T1）。此类参数同时覆盖全海浪场以及分离后的风浪与涌浪分量，二者的分界周期为8秒。方向数据额外包含风浪与涌浪分量在峰值周期（Tp）时刻的传播方向，该方向以相对于磁北的角度值表示，由波浪浮标在由后处理软件计算得到的峰值周期（Tp）时刻实测计算得出。
