Abstract

In this paper, a visual analytics system that are used to analyze the causal relation- ship between fishing catches data in adjacent sea areas is proposed. By using the proposed system, the distribution of sea surface temperature is visualized so that the sea areas can be divided accordingly. Next, the daily fishing efficiency in each sea area are calculated and the convergent cross mapping is used to analyze the causality between the data in adjacent sea areas. The experimental results show that the possible causation between the data in two of the divided sub sea areas are detected. In addition, the causal variable can be further identified by referring to the prediction skills.
