The inversion of ocean subsurface temperature and salinity (TS) is a hot topic and challenging problem in the oceanic sciences. In this study, a new method for the inversion of underwater TS in the South China Sea is proposed based on an improved generative adversarial network (GAN). The proposed model can derive the underwater TS from sea surface...

The Array for Real-time Geostrophic Oceanography (Argo) program provides valuable data for maritime research and rescue operations. This paper is based on Argo historical and satellite observations, and inverted sea surface and submarine drift trajectories. A neural network method was developed to predict the position of Argo buoys, improving targe...

Plain Language Summary Generative adversarial networks (GANs) are undoubtedly one of the most creative advances in deep learning due to their excellent generation performances, but they are not widely used for interior ocean variables' deriving. Deriving sea subsurface temperature fields from satellite remote sensing data using deep learning method...

This paper introduces the realization algorithm of ocean element curves and profiles on GIS. The algorithm projects the curves and profiles of ocean elements onto the geographic map. It realizes the combination of two-dimensional spatial geographic location, time dimension of curve change and spatial dimension of vertical profile, and displays thre...

The United Nations Convention on the Law of the Sea provides only basic legal principles for maritime delimitation disputes among coastal states. The implementation of maritime delimitation requires the comprehensive use of legal, political, and technical means by relevant states to generate the expected equitable results. Accurate calculation of t...

The benthic structure of seamounts is critical for understanding the ecological environment and for assessing the influence of resource exploitation. However, the characteristics of the benthic structure of the seamount, especially for guyot, are still far from being clearly understood. For the first time, we carried out detailed hydroacoustic mapp...

Global warming has intensified the rise in sea levels and has caused severe ecological disasters in shallow coastal waters such as the Northeastern China's Bohai Sea. The prediction of the sea surface height anomaly (SSHA) has great significance in the context of monitoring changes in sea levels. However, the non-linearity of SSHA due to the occurr...

Housing is among the most pressing issues in urban China and has received considerable scholarly attention. Researchers have primarily concentrated on identifying the factors that influence residential property prices and how such mechanisms function. However, few studies have examined the potential factors that influence housing prices from a big...

Inventory control in hybrid manufacturing/remanufacturing systems (HMRS) with stochastic demand and return will be investigated in this paper. An integrated PUSH and PULL inventory policy is proposed for combining the advantages of the PUSH and PULL inventory policies. A dynamic model for inventory control in HMRS will be developed to seek the mini...

Two fuzzy models for inventory control in hybrid manufacturing/ remanufacturing systems were developed on the basis of the assumption that the demand rate and the return rate are characterized by triangular fuzzy numbers. The signed distance method is employed to derive the estimate of total cost per unit time. In addition, simple modifications of...
