Fast and flexible spatial sampling methods based on the Quadtree algorithm for ocean monitoring

Although existing in situ oceanographic data are sparse, such data still play an important role in submarine monitoring and forecasting. Considering budget limitations, an efficient spatial sampling scheme is critical to obtain data with much information from as few sampling stations as possible. Th...
