S4ADW浪潮仪测量与资料后处理关键技术

Key Technologies of Measuring and Data Post-processing with S4ADW Wave-Tide Gauge

海上石油水文勘探调查涉及海浪、海流等多种水文要素,S4ADW浪潮仪作为为数不多的能同时测量海浪、海流要素的设备,在浅海观测中灵活度高,应用广泛,采用坐底式观测,不易受海上恶劣环境的破坏,能够持续得到石油水文勘探调查所需要的海浪、海流的同步观测数据。但是在实际操作和后期数据处理过程中该仪器尚存在一些自身问题,限制了该仪器的观测能力。本研究就S4仪器自身及其波浪处理软件方面所存在的典型问题进行了讨论,并提供了一套实用的解决方案,填补了该仪器使用经验方面的空白,可供国内外S4用户参考。

Many hydrological elements such as sea waves and currents and so on are in- volved in the offshore petroleum hydrologic survey. As the few instruments that are a- ble to measure both waves and currents simultaneously, the S4ADW wave tidal gauge is flexible to-use in the shallow water observations, widely applied and unaffected by the severe weather conditions, and also can continuously acquire the simultaneous observa tion data of waves and currents in the offshore petroleum hydrologic surveys. However, problems which limit the investigation capability of the equipment still exist in the prac- tical operation and data post-processing procedures. Of them, some typical ones con- cerning both the S4 equipment itself and the wave processing software are discussed and a series of practical solutions are also proposed. All these have filled the blank of the ex- periences in using this device and can be as good references for the S4 users at home and abroad.
