“…The methods using the graph convolutional neural network and the GCN-LSTM model further improve the accuracy and have the best predictive effect. A more accurate SST prediction will provide solid technical support for responding to the challenges in marine biology [1,2], the global climate [3,4], and extreme weather events [5].…”

Sea surface temperature (SST) prediction plays an important role in scientific research, environmental protection, and other marine-related fields. However, most of the current prediction methods are not effective enough to utilize the spatial correlation of SSTs, which limits the improvement of SST prediction accuracy. Therefore, this paper first explores spatial correlation mining methods, including regular boundary division, convolutional sliding translation, and clustering neural networks. Then, spatial correlation mining through a graph convolutional neural network (GCN) is proposed, which solves the problem of the dependency on regular Euclidian space and the lack of spatial correlation around the boundary of groups for the above three methods. Based on that, this paper combines the spatial advantages of the GCN and the temporal advantages of the long short-term memory network (LSTM) and proposes a spatiotemporal fusion model (GCN-LSTM) for SST prediction. The proposed model can capture SST features in both the spatial and temporal dimensions more effectively and complete the SST prediction by spatiotemporal fusion. The experiments prove that the proposed model greatly improves the prediction accuracy and is an effective model for SST prediction.

“…Sea surface temperature (SST) changes have significant impacts on marine biology [1,2], the global climate [3,4], and extreme weather events [5], such as decreasing marine species diversity, altering global wind patterns, and increasing the incidence of floods. It also creates challenges for the ecosystem and for human life [6].…”
