50 Years of Harmful Algal Blooms: Rotating Globe Unwraps to Robinson Projection
This data visualization shows 50 years of algal blooms collected across a spinning globe. Once all the data is accumulated, the globe then unwraps into a Robinson projection so the viewer can see the entire global dataset.
Mass fish deaths have ridden our planet's beaches and coastlines. New health risks have taken over coastal communities and millions of fishery-based employees are out of work. To bring light to the issue and show how new technology may revolutionize data we collect the current best data available to show the scope of the problem. As our global climate continues to change, more nutrients enter our water sources, coastal waters get warmer, algal blooms will continue to flourish in this ideal environment.
In January 2024, NASA is scheduled to launch the PACE satellite which is designed to improve and increase the data we have collected surrounding harmful algal blooms.
This data visualization depicts the scope of the data we currently have collected over the past 50 years. Much of it is taken from ships at sea and inland water ways. From this we can see that this is a global issue and learning more about this problem will greatly further our understanding of the issue at hand.
