Ocean Data Visualization Software (ODV and JOA) and New Applications in Marine Geochemical Studies

Climate and biogeochemical cycle are important issues in marine sciences research fields, and the demand for fully utilizing and deeply mining marine geochemical data is growing.The internal structure of the ocean is complex and the interaction processes are diverse. The study of the internal mechanism and biogeochemical cycle of the ocean usually requires collaborative analysis of various marine physical and chemical parameters. Therefore, ocean data visualization software becomes more and more important. At present, there are few Chinese guides on the use of ocean data visualization software. Detailed description of operation level is required. Here we outline the basic functions of two data visualization softwares: Ocean Data View (ODV) and Java OceanAtlas (JOA), and provide a detailed practical guide on the production of map, section, surface, scatter, station and waterfall for the visualization, with a comparison of the differences between the two software. We also give examples of some new applications of ODV within the broad field of marine geochemistry.
