NASA Satellite Captures Massive Wastewater Flow off California Coast

In 2022, NASA’s reactive immigration laboratory launched a satellite sensor to map minerals in the dusty areas of the Earth. However, it is not useful for a new job, scientists used a spectroscopic tool to study the magnifying amount of water from the Southern California coast.

Every year, millions of cents are not cleaned and treated, and treated, without reaching the ocean, the Tijuana River is transferred to the Tijuana River through communities on both sides of the United States. In a study published in the magazine The science of the general environmentResearchers were using Earth Surface Mineral Dust Source Investigation (Emit), a hyperspektral image tool from the International Space Station in this nauseating in the Tijuana River delta.

Pollution from sewage is not pretty. Toxic chemicals can bring harmful algal flowers and unfriendly bacteria, which can affect the health of the beaches.

People generally rely on areas where it is always dangerous to swim, it always covers the full degree of pollution. It also requires time and money to collect samples, especially in severe contaminated areas.

That is Patch up enters. This uses image spectroscopyIt is a technique that measures both space and spectral information by measuring sunlight and reflects the surface of the earth. Each image can seize hundreds of wavelengths per pixel, scientists provide detailed information by providing information on the molecular content and material features on the ground.

This allows researchers to measure the spectral signature of the wastewater. Researchers compared untreated wastewater, unprediated wastewater and plums with hyperpectric satellite images taken with nearby seawater. They compared the pictures of the emit with readings from a spectrometer on the ground. With high wastewater pollution, the water spreads a different red spectral feature that can allow researchers to follow the future contamination and the source of this feature is still unknown.

Researchers hope that the information hopes that the rivers can sample the quality of water near the mouth of the water near the mouth of the water.

Now the issue has another job. “The findings of the findings on the coast are the corresponding to the measurements in the field,” Eva Scrivner is the author of a doctoral student and research at Connecticut University. “Really excited.”
