Scientists have recently made a significant breakthrough in utilizing satellite technology to detect pollution in Earth’s oceans. Dutch researchers from Deltares have discovered how to effectively use satellites to locate floating plastic debris in ocean waters.
By using a combination of microwave sensors to detect trash and monitor water conditions, as well as optical sensors to identify different types of plastic based on color and infrared properties, the researchers have been able to continuously monitor pollution hotspots and identify new ones.
Their research found that microwaves were particularly useful in detecting plastic, even in small quantities, with the ability to locate as little as one item per square meter using X- and Ku-wavelengths.
Plastic waste is a rapidly growing issue for the planet, leading to the spread of microplastics in water bodies and posing significant threats to marine life. However, a recent discovery of a chemical produced by mussels that can help break down plastic waste offers hope in combating this problem.
The researchers hope that their study can be further tested in oceans worldwide to track plastic waste on a global scale. The European Space Agency (ESA) anticipates that this research will aid in developing space-based technologies for monitoring ocean pollution and implementing interventions in severely affected areas.
As efforts continue to address the plastic waste crisis, the collaboration between scientists and innovative technology offers a promising outlook for the future of ocean conservation.
