☆ Alaska's pristine rivers are turning a rusty orange even when seen from space, likely because of melting permafrost: study

Read previewAt least 75 of Alaska's brooks and streams have been turning a dirty orange likely due to thawing permafrost, with some rivers so impacted that the discoloration can be seen via satellite, a new study says. Rivers and lakes typically have a pH value of 6.5 to 8, and acid rain has a pH value of 4.2 to 4.4. Jon O'Donnell/National Park Service"These findings have considerable implications for drinking water supplies and subsistence fisheries in rural Alaska," researchers wrote. The 75 orange streams observed were scattered across northern Alaska over a span of about 600 miles, the study said. AdvertisementAn orange tributary joins the Kuguroruk River in Alaska.

☆ Alaska's once crystal-clear rivers now resemble dirty orange soda, puzzling researchers

The melting permafrostEven before researchers knew about the orange waters, they realized northern Alaska was rapidly changing. The Arctic Inventory and Monitoring Network mapped locations of orange streams, and aerial photos show how easy they are to spot because of their brightness. When scientists went to the orange streams to count fish, insects, algae, and other aquatic life , "biodiversity just crashed," biologist Mike Carey told Scientific American . Advertisement"The fish were totally gone," Koch told BI. The streams Koch monitors near the Brooks Range are fairly remote, but the rivers they feed into provide fish for human communities in this region.
