Based on analysis of the study of the sea surface temperature data and application, the author put forward a Web Service-based application framework for sea surface temperature information. The use of Web service was proposed to solve the problems in heterogeneity, distribution, and efficiency triggered by networking. A prototype application was successfully designed based on the framework, namely: The Application Service Platform of Sea Surface Temperature Information in the South China Sea. It can integrate heterogeneous sea surface temperature data services and application services, and provide users with transparent, “one-stop” web applications on sea surface temperature. Users can access the platform to search and fetch valuable information and value-added applications. On the platform, all of the heterogeneous and distributed sea surface temperature information is encrypted, decrypted, monitored, and hence interchangeable according to international standards. The results confirm the feasibility of the application of Web Services to sea surface temperature information integration, and this study can also be referenced by other marine information.
