The North American Great Lakes are the largest freshwater system on Earth. Those wishing to dive in have an enhanced resource: The Great Lakes Observing System (GLOS) has launched an updated website at
The site was developed for Great Lakes data users, and provides improved access to data, products, tools and information on GLOS projects.
“(GLOS) provides a key infrastructure for the expansion of beach water-quality ‘nowcasts,’ which can improve public safety and reduce the number of unnecessary advisories and beach closures throughout the Great Lakes,” according to Adam Mednick, a research scientist at the Wisconsin Department of Natural Resources.
“The redesigned GLOS website makes accessing meteorological and hydrodynamic data needed to operate daily nowcast models more efficient — and makes it easier for state, local, and federal partners to collaborate on the development and implementation of these systems.”
The Great Lakes Observing System is a nonprofit association that works to connect data users with data providers to support policy and decision-making.
GLOS is one of 11 regional associations of the Integrated Ocean Observing System, a partnership effort of 17 U.S. federal agencies led by the National Oceanic and Atmospheric Administration.
