NASA to launch satellite to track rising sea levels

NASA plans to launch a satellite tomorrow that can comply with the consequences of local weather change on the world’s oceans and collect knowledge to enhance climate forecasts. The satellite will proceed NASA’s three decades-long work to doc rising sea levels and can give scientists a extra exact view of the coastlines than they’ve ever had from house.

“The best front seat view on the oceans is from space,” says Thomas Zurbuchen, head of science at NASA.

The Sentinel-6 Michael Freilich satellite will launch from Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket. NASA’s stay protection of the occasion will begin at 8:45AM PT on its web site, with the launch anticipated to happen at 9:17AM. The satellite is the primary of a pair of ocean-focused satellites, which can lengthen NASA and the European Space Agency’s analysis on international sea levels for an additional ten years. The subsequent satellite, the Sentinel-6B, will comply with in about 5 years. To measure sea levels, they’ll beam electromagnetic indicators down to the world’s oceans after which measure how lengthy it takes for them to bounce again.

When NASA started its work on sea stage rise within the Nineties, scientists had been nonetheless interested in whether or not predictions in regards to the influence of local weather change had been coming true, in accordance to Zurbuchen. “The question of whether the oceans go up or not [as the planet heats up] has been settled by these satellites, it’s not a question,” Zurbuchen tells The Verge. “Just as sure as gravity right here where I’m sitting, these oceans are going up and we need to handle what that does to our lives.”

NASA scientists can be in a position to make higher-resolution observations a lot nearer to shore with the brand new satellites, which can enable for extra exact climate forecasts simply earlier than storms make landfall. As an enormous storm develops over the sea, the water buckles up. A satellite can decide up on that bubble of water rising and use that data for forecasts. The granular measurements may be used to see how modifications in sea stage close to coastlines may have an effect on ship navigation and industrial fishing.

Tides are creeping additional ashore on account of local weather change. That’s as a result of water expands because it heats up and since the world’s glaciers and ice sheets are melting. The encroaching water makes flooding and storm surges more and more harmful. It’s additionally drowning total islands and coastal communities. That’s already pressured folks from Louisiana to Papua New Guinea to abandon the locations they’ve referred to as dwelling for generations.

“What the question today is, what’s the impact [of sea level rise] and what can we do about it?” Zurbuchen says. “Those are the questions that matter to my family, to my friends, to all of our families because they affect how our families can live in the future.”
