Fertilizers used in farming contain high amounts of nutrients, such as phosphorous, to help crops grow. But these same nutrients can cause unwanted plant growth and potentially harm ecosystems miles away if agricultural runoff flows into nearby rivers, lakes, or coastal waters.
From the vantage point of space, NASA’s fleet of Earth-observing satellites investigates connections between ecosystems that are continents apart, or right next door.
Saharan Dust Forecasts Minimize Health Risks in the Caribbean
Landsat imagery shows that the area covered by kelp forests off the coast of Northern California has dropped by more than 95 percent, with just a few small, isolated patches of bull kelp remaining. Species-rich kelp forests have been replaced by “urchin barrens,” where purple sea urchins cover a... Read More

NASA Harvest and CropX Partner to Support Sustainable Ag
Earth is on a budget – an energy budget. Our planet is constantly trying to balance the flow of energy in and out of Earth’s system. But human activities are throwing that off balance, causing our planet to warm in response.
Colorful bursts of energy above thunderstorms called transient luminous events can be observed from the International Space Station. Instruments on the station are helping scientists study these particle outbursts, which may prove useful to better understand our climate, weather, and the behaviors... Read More
