Researchers from the Montana State University collaborated with the researchers from the University of Applied Sciences in Germany to study the extent and type of effect that tourism can have on our natural environment.
With the help of a simple mathematical model, the original colors of Yellowstone National Park’s hot spring pools were rebuilt by the researchers. The mathematical model made use of optical measurements to study the effect of physical and chemical substances on the spring pools.
The color of the pools altered because large number of coins and waste were thrown by tourists in the hot springs. From decades, the pools have been contaminated by tourists they throw make-a-wish coins and other trash. This causes the chemistry of the pools to alter, thereby turning them into green. The researchers said that originally the pools were deep blue in color.
For the process of the reconstruction, DSLR cameras have been used by the researchers. This was done to view all the stuff that can be noticeable to the human eye. They also made use of long-wave thermal imaging cameras to obtain readings for the water temperature in the pools, and hand held spectrometers.
The harmful impact that has been caused by tourism to this lovely place has been checked by the findings of the study. According to history, tourists started visiting this place around the 1940s. At this time, tourists began making use of the spring pools as wishing wells where tourists tossed their coins and made a wish.
