Algal blooms occur frequently in the Yangtze River Basin, yet the public’s awareness and concern about ecological issues in the region remain insufficient, which continues to be a societal problem. Information visualization design plays a crucial role in enhancing public understanding and awareness of ecological issues. The goal of designing public-oriented information visualization installations is to transform complex scientific data into forms that are easy for the public to comprehend through intuitive and engaging means.

Project Overview

The experience is structured into three parts to guide users in a progressive manner to deepen their understanding of algal blooms in the Yangtze River:

Real-Time Temperature Data Visualization: A visualization installation driven by real-time temperature data simulates the occurrence of algal blooms in Taihu Lake and Chaohu Lake. This artistic representation aims to convey the sporadic nature of algal blooms and encourages viewers to reflect on the connection between human activities and the emergence of these phenomena.

Two-Dimensional Infographics: The current status of algal blooms in the Yangtze River Basin is presented using infographics that illustrate the causes of algal blooms, their types, and the diversity of algae. This visually engaging format provides a clear overview of the situation.

Three-Dimensional Modeling: Using petri dish-like displays, three-dimensional models artistically showcase the forms of various algae. This adds an aesthetic dimension to the scientific information, allowing users to appreciate the beauty and complexity of these organisms.

The simulation of algal bloom occurrence and spread is achieved through the dripping of algal powder liquid, creating an effect that visually represents the growth of algal blooms. The localized details of this simulation reveal that the algal powder liquid spreads outward on the paper, exhibiting a directional flow.

Additionally, the position and flow rate of the droplets correlate with the locations and temperatures where algal blooms occur. Urban and agricultural areas typically provide abundant nutrients that promote algal growth, resulting in varying visual effects across different lakes.
