The Cosmos with Suwannee River


In a dense swampland in Georgia, just north of the Florida border, you find the headwaters of the Suwannee River. The Suwannee is known as a “blackwater river” because of its dark-brown waters laden with organic material. This river system has been called one of the most pristine in the United States, but some environmental pressures are putting that distinction in jeopardy.

Unlike other blackwater rivers, the Suwannee maintains its inky color along its entire 400-kilometer (250-mile) journey to the sea. When the river finally meets the Gulf of Mexico along Florida’s Big Bend—that portion of coast where the state’s panhandle curves to meet its peninsula—its dark waters act like a tracer, revealing whereby the river water mixes with the sea. That mixing was on display on February 20, 2015, when the Operational Land Imager on Landsat 8 captured this view.

The image above was entered into NC State’s Envisioning Science image contest by Alice Alonso, a former research scientist in the university’s Biosystems Analytics Lab and now a researcher at the Université catholique de Louvain. As she described, the image “captures a large river discharge event, which resulted in a mesmerizing dark river plume contrasting with the deep blue color of the Gulf of Mexico.” It is, in effect, a testament to the freshwater contribution of the Suwannee River to the sea and an echo of the unique, swampy ecosystem.
