Colorado River Fish Contain Levels Of Selenium, Mercury

Largely seen as pristine and relatively untouched by human activity thanks to its protected status, the portion of the Colorado River flowing through Grand Canyon National Park is anything but, according to recently published research. This is evidenced by high levels of selenium and mercury found in the fishes there. Scientists from many institutions were involved in the years-long work, full results of which have been published in the journal Environmental Toxicology and Chemistry. It was led by the U.S. Geological Survey, but perhaps the contributors from Idaho State University got the best end of the stick. They were looking into the food webs of the river to evaluate concentrations of selenium and mercury gathering in fish.

Cellular Data Buoy Supports Lake Erie Algae Research, Public Outreach

Scientists at Ohio State University are at the fore of the fight against harmful algal blooms in Lake Erie. In fact, they deployed a new cellular data buoy off the shore of Gibraltar Island in 2014, months before the Toledo Water Crisis spurred a boom in monitoring platforms around the lake. That was in part because researchers at the university’s Stone Laboratory, backed by Ohio Sea Grant and housed on Gibraltar, had been seeing a resurgence of blooms in the lake long before international attention came around following the crisis. There was an opportunity, they saw, to continue advancing the mission of research, education and outreach on Lake Erie. The cellular data buoy complimented that in a great way.
