NASA shows how plastic behaves in the ocean | Digital Trends Spanish


Plastic is one of the most polluting materials that exist. The problem is that this waste is very difficult to degrade so, unfortunately, in most cases it ends up in the ocean.

In fact, it is estimated that each year about 8,000 million kilograms of plastic reach the different oceans of the world, which constitutes a serious environmental problem.

It is often difficult to imagine this large amount of garbage floating in the water. For this reason, NASA shares a video that shows the behavior of these debris.

University of Michigan.

This is the first research of its kind that seeks to map plastics on a global scale and in a given period.

Thus, the animation shows concentrations of plastic moving in the planet’s oceans during a period of 18 months.

The registry allows us to appreciate in which regions concentrations of plastic garbage accumulate and for what reasons it is so difficult to eradicate.

Unpublished work

NASA was based on a new model for tracking and mapping the path that plastic makes in the world’s seas developed by researchers at the University of Michigan.

“In cleaner waters there is a high degree of agreement between ocean roughness and wind speed,” says part of the research.

“But as you head into the great Pacific garbage patch, you can see a greater discrepancy between measurements of wind speed and surface roughness.”

During the research, the scientists spotted some interesting elements, including the way that garbage concentrations in some regions of the Pacific increase in summer and decrease in winter.

The researchers now hope that this unprecedented mapping will help authorities think of more practical and effective ways to clean up the plastic trash that pollutes the oceans.
