In the aftermath of Hurricane Ida, Louisiana Maps could never look the same

Satellite iwise of Louisiana which was taken before and after HUrricane Ida is showing a dramaticly changing coastline, many low-lying areas still have water. Scientists are closely observing the site to see how it changes over time, as well as whether other changes are temporary.

Hurricane Ida made fall on August 29— 16th year of Hwind Katrina. Group 4 staged a riot in Louisiana, beating the government with strong winds, heavy rain, and more a storm. Ida was one of the strongest hurricanes to hit the state, causing power outages, destroying homes and businesses. destroying roads and bridges, and destroying Death 26 in government.

It also changed the place, although we do not know for how long. Ida passed along the shores of the Mississippi Delta, an area at risk of endangering Atlantic O dangerresponded Rivers, northern dams, and rising tides as a result of climate-induced climate change are causing the salt marshes to slow down. Other human activities, such as pumping groundwater and oil, also contribute to the project, such as the natural depth and stability of the new soil, according to via NASA’s Earth Observatory.

Land photographs taken before and after the storm show the changes in the river. The satellite image of Landsat 8 shows the New Orleans region as it was in September 19, 2015, then as it appears on September 3, 2021, Five days later Ida hit the circuit.

Muddy waters appear glossy blue in false positives-color images. A natural image of the same type (below) shows muddy waters in unspoiled lands, especially Lake Maurepas, Lake Pontchartrain, and the northwest coast of Lake Borgne.

The floodwaters were there for five days after the storm. The rivers, coastal ports, lakes, and swamps in the parks of Lafourche, Jefferson, and Plaquemines are less well known. Satellite imagery of the area in Lafourche Parish near Larose indicates a fixed position near the lower farm.

“The combination of floods, landslides and eruptions during the Ida era must have caused a lot of open water to be seen in the Landsat spacecraft,” Marc Simard, a senior researcher at NASA’s Delta-X mission, told Earth Observatory.

The Delta-X project on the Mississippi Delta is currently undergoing mud and water changes due to Hurine Ida. Later this month, when the water recedes, the team will walk down the aisle and use boats to monitor the area., in addition to the use of space radars.

“One of the great things to watch and see if the big change you see in this Landsat image is to be temporary or long-term,” said Simard. “Some of the losses may have been floating seeds that had been washed away or plants that had just lost their leaves to grow and perhaps regenerate. Some have been uprooted and will never again provide protection by the coast as in the past. ”

The Delta-X team is planning to track the salt content to see if the salt marshes are able to enter the salt marshes. They are also anticipating the abundance of river mud, which can fill coastal areas and provide shelter for crops.

“I think we will see that the wetlands with a lot of mud coming in will be much stronger than wetlands that receive little or no income from rivers,” said Simard. “We hope that the species created by Delta-X scientists will provide insight into the complex problems of wetlands development in the region in the future.”

Being an important word. Climate change that causes human suffering means that the Mississippi Delta is now under attack by nature, and it may never return. And, of course, there’s always the next big storm.
