East Victoria long term hydrodynamic modelling: dataset and methodology

This dataset is the output of a long term multi-resolution calibrated hydrodynamic model of Bass Strait waters in south-eastern Australia. The model has been developed to support a subsequent study which investigated the influence of habitat created by platforms and subsea pipelines operated by Esso Australia Pty Ltd (EAPL) for population connectivity of key marine biota. The model is 3 dimensional with 16 sigma layers. It is forced by tides, wind, non-tidal sea level variability as well as salinity and temperature through a nudging scheme. Stokes drift from gravity waves was added to the model output as a post-processing step. The model was calibrated against existing data from previous fixed location instrument deployments and hull mounted ADCP data. While the model has limitations, it performs well against measured data and provides a useful tool for describing spatially varying currents throughout East Victorian waters.The dataset is the output from a 3-dimensional hydrodynamic model used to describe physical oceanographic processes. The data were generated using a numerical model to simulate 10 years of hydrodynamics around Eastern Victoria in Australia.本数据集为澳大利亚东南部巴斯海峡（Bass Strait）海域长期多分辨率校准水动力模型的输出结果。该模型旨在支撑后续一项研究，该研究探究了埃索澳大利亚私人有限公司（Esso Australia Pty Ltd，EAPL）运营的钻井平台与海底管线所营造的生境，对关键海洋生物种群连通性的影响。该模型为三维模型，包含16个σ坐标层。模型由潮汐、风场、非潮汐海平面变化驱动，并通过逼进方案（nudging scheme）同化盐度与温度数据。研究通过后处理步骤，将重力波产生的斯托克斯漂流（Stokes drift）加入模型输出结果中。该模型基于既往定点仪器观测数据与船体搭载式声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）数据完成校准。尽管该模型存在一定局限性，但与实测数据对比表现优异，可作为描述东维多利亚州海域空间变化海流的有效工具。 本数据集为用于描述物理海洋过程的三维水动力模型的输出结果，其数据通过数值模型模拟了澳大利亚东维多利亚州周边10年的水动力过程。
