Rising sea temperatures and shifting tidal patterns, fuelled by climate change, cause formidable threats to marine ecosystems. Accurate prediction of sea surface temperature (SST) and tidal height (TH) is essential to address these challenges. Recently, many studies have used machine learning or deep learning to predict SST and TH. However, achieving more precise predictions for SST and TH remains crucial. In this paper, we introduce an innovative deep learning approach that combines ensemble learning techniques with multi-featured spatiotemporal deep learning models to accurately predict SST and TH. First, we train a temporal model using LSTM for the nearby sea areas of the target prediction location. Then, we use various ensemble learning (EL) techniques to integrate the models of these nearby sea areas, forming a multi-featured spatiotemporal model (STH-LSTM). We test our model in the Penghu Sea area near Taiwan (Penghu, Dongji, Qimei, Jibei, Jiangjun, and Wangang) using data from the Central Weather Bureau (CBW) from 2020 to 2022. The ensemble techniques employed include STH-MLR-LSTM, STH-AGG-LSTM, STH-MAE-LSTM, and STH-SAM-LSTM. In this study, we evaluate the proposed model's performance using metrics such as Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and the coefficient of determination (R 2 ), alongside comparative analyses against SVR (Support Vector Regression), AdaBoost, and RF (Random Forest) models. The results show that STH-MLR-LSTM achieves the be...
