The Florida Everglades is a swampy wilderness the size of Delaware. In some places along the road in southern Florida, it looks like tall saw grass to the horizon, a prairie punctuated with a few twisted cypress trees. The sky is the palest blue. But beneath the surface a different story is unfolding. Because of climate change and sea level rise, the ocean is starting to seep into the swampland. If the invasion grows worse, it could drastically change the Everglades, and a way of life for millions of residents in South Florida.
An experiment is going on here to help scientists understand more about what’s likely to happen as the ocean invades. “We’re making, basically, artificial seawater here,” a guy wearing a mosquito net over his face tells me, as he stirs water in a vat the size of a hot tub. The guy in the mosquito net is Joe Stachelek — a collaborator with Tiffany Troxler, from Florida International University. They’re making salt water and pumping it out into the wetland — dosing the plants and soil with their briny mix as a preview of what the ocean could do.
“As sea level rises,” Troxler explains, “the saltwater wedge moves inland.” And it infiltrates the bedrock. Read more >>
