The Great Lakes Observing System coordinates Great Lakes data collection, management, and sharing. 

The Great Lakes Observing System (GLOS) provides end-to-end data services that support science, policy, management, and industry in the Great Lakes.

A binational nonprofit, GLOS aims to enable easy access to the real-time and historical lake data that the people of the region need.

By taking a user-oriented approach to organizing the technologies, people, and processes involved in monitoring the Great Lakes, GLOS is building a system where data is sharable and interoperable so that our immensely valuable freshwater resources can be better managed and more fully understood.

Our focus falls into the following categories: maritime safety, ecosystems and fisheries, public health, and climate adaptation. Read more

An IOOS Regional Association

GLOS is one of 11 Regional Associations of the Integrated Ocean Observing System (IOOS), working to enhance the ability to collect, deliver, and use ocean and Great Lakes information. IOOS is a partnership among federal, regional, academic and private sector parties that work to provide data for tools and forecasts to improve safety, enhance the economy, and protect our environment.

IOOS supplies critical information about our nation’s oceans, coasts, and Great Lakes. Scientists working to understand climate change, governments adapting to changes in the Arctic, municipalities monitoring local water quality, and industries affected by coastal and marine spatial planning all have the same need: reliable, timely, and sustained access to data and information that inform decision making.

Improving access to key marine data and information supports several purposes. IOOS data sustain national defense, marine commerce and navigation safety. Scientists use these data to issue weather, climate and marine forecasts. IOOS data are also used to make decisions for energy siting and production, economic development, and ecosystem-based resource management. Emergency managers and health officials need IOOS information to make decisions about public safety. Teachers and government officials rely on IOOS data for public outreach, training and education.

GLOS is a certified Regional Information Coordination Entity for the U.S. IOOS network. Being certified means organizational and operational practices, including data management, meet recognized standards set by NOAA.
