The project overall aims to develop an optimised satellite-derived bathymetry model for monitoring offshore sandbanks in the southern North Sea using optical satellite data. This will help us to understand whether there have been any significant changes after the development of offshore wind farms. This will be achieved using these intermediate objectives, each of which builds from the work of the previous: Create an optimised pre-processing method to use with an industry standard satellite-derived bathymetry methodology, if necessary, refining a current pre-processing method if it is not currently optimised for oceanic data. Understand current sediment transport models, that are based on satellite data, and integrate the best fit into the satellite derived bathymetry, investigating statistically whether the change improves the accuracy. Consider different satellite-derived bathymetry models, to confirm whether the industry standard method is the most appropriate in this use case. This includes the integration of the pre-processing methodology and sediment transport model. If required, develop a statistically more accurate model using an alternate method. Using an optimised satellite-derived bathymetry model, track sandbanks over time.

该项目的总体目标是开发一种优化的卫星测深模型，用于使用光学卫星数据监测北海南部的近海沙洲。这将有助于我们了解海上风电场发展后是否有任何重大变化。这将利用这些中间目标来实现，每个中间目标都建立在前一个目标的基础上：创建一种优化的前处理方法，以便与行业标准的卫星测深方法一起使用，如有必要，改进目前的前处理方法，如果它目前没有针对海洋数据进行优化。了解目前基于卫星数据的泥沙输送模型，并将最佳拟合融入卫星得出的水深测量中，从统计上调查这种变化是否提高了精度。考虑不同的卫星测深模型，以确认行业标准方法是否最适合此用例。这包括将前处理方法与泥沙输移模型相结合。如果需要，使用另一种方法开发统计上更准确的模型。使用优化的卫星水深测量模型，追踪沙洲随时间的变化。
