Globally-covered ocean monitoring system Argo with more than 3,700 floats has been working, and its accumulated big ocean observation data helps many studies such as investigation into climate change mechanism. Since the observed data sometimes involves errors, human experts must visually confirm and revise quality control (QC) labels. However, such manual QC by human experts cannot be performed in...
In the ocean around the world, depth series ocean data of temperature and salinity have being measured. However, it is difficult to discriminate the errors from the normal data since the variation of ocean areas are different. In this research, using hierarchical clustering, we partitioned the ocean into some areas so that the ocean data have the same variation in each area. Then, transforming the...
Globally-covered ocean monitoring system Argo with more than 3,600 small and light-weight drifting buoys is always working for oceanic temperature and salinity measurement. The accumulated big ocean observation data helps many studies such as investigation into climate change mechanism. Although human experts visually confirm and revise quality control (QC) labels, it is difficult to regularize the...
