Great Lakes Observing System

Great Lakes Observing System (GLOS) is a nonprofit environmental monitoring organization headquartered in Ann Arbor, Michigan. Established in 2004, the organization coordinates the collection, management, and distribution of scientific data related to the Great Lakes. Through partnerships with government agencies, universities, research institutions, industry, and nonprofit organizations, GLOS supports water monitoring, weather forecasting, navigation safety, environmental stewardship, and scientific research throughout the Great Lakes basin. GLOS serves as the federally recognized regional observing system for the Great Lakes under the Integrated Ocean Observing System (IOOS) network. ^{1) 2)}

The Great Lakes Observing System was established in 2004 in response to growing recognition of the need for coordinated environmental monitoring across the Great Lakes region. Scientists, government agencies, shipping interests, environmental organizations, and policymakers sought a unified system capable of collecting and sharing real-time information regarding lake conditions, weather, water quality, and ecosystem health. ³⁾

The organization became part of the broader national Integrated Ocean Observing System framework administered through the National Oceanic and Atmospheric Administration (NOAA). ^{4) 5)}

GLOS works to improve understanding of the Great Lakes through data collection, technology integration, and information sharing. Its mission focuses on providing reliable environmental information that supports decision-making by researchers, mariners, resource managers, policymakers, and the public. ⁶⁾

The organization serves as a central hub connecting diverse monitoring programs operating throughout the Great Lakes basin. ⁷⁾

One of GLOS's primary responsibilities is supporting monitoring systems across the Great Lakes. Data collected through these systems include:

* Water temperature * Wave height * Wind speed and direction * Ice conditions * Water levels * Currents * Water quality measurements * Meteorological observations

This information assists researchers and operational users in understanding changing conditions throughout the region. ⁸⁾

GLOS supports a network of observation platforms that include monitoring buoys, weather stations, coastal sensors, autonomous vehicles, and remote sensing technologies. ⁹⁾

These systems collect data continuously and provide real-time information that can be accessed by scientists, commercial operators, recreational boaters, emergency managers, and government agencies. ¹⁰⁾

The organization's observation network covers portions of:

* Lake Superior * Lake Michigan * Lake Huron * Lake Erie * Lake Ontario

A significant portion of GLOS's work involves integrating information from numerous agencies and research institutions into accessible data platforms. These systems allow users to locate, visualize, and analyze environmental information from across the Great Lakes basin. ¹¹⁾

The organization's data resources support scientific research, environmental management, transportation planning, emergency response, and public education. ¹²⁾

The Great Lakes support one of the largest freshwater transportation networks in the world. Accurate environmental information is critical to commercial shipping, recreational boating, fisheries, and port operations. ¹³⁾

GLOS data assists mariners by providing information about wave conditions, weather patterns, currents, water levels, and ice coverage. These services contribute to safer navigation throughout the region. ¹⁴⁾

GLOS works closely with universities, government agencies, environmental organizations, and research institutions. Collaborating organizations include:

* University of Michigan * Michigan State University * NOAA * United States Geological Survey * Environment and Climate Change Canada

These partnerships help advance scientific understanding of Great Lakes ecosystems and environmental processes. ¹⁵⁾

The Great Lakes contain approximately twenty percent of the world's surface freshwater and represent one of North America's most significant natural resources. GLOS contributes to stewardship efforts by supporting data-driven management of water quality, fisheries, coastal habitats, invasive species, and ecosystem health. ^{16) 17)}

The information generated through monitoring programs assists policymakers and resource managers in addressing environmental challenges affecting the region. ¹⁸⁾

Because GLOS is headquartered in Ann Arbor, Michigan, the organization maintains strong ties to Michigan universities, research institutions, environmental agencies, and Great Lakes communities. ¹⁹⁾

Michigan's extensive shoreline along four of the five Great Lakes makes environmental monitoring especially important for transportation, tourism, fisheries, recreation, and water resource management. ²⁰⁾

The Great Lakes Observing System has become one of the most important environmental information networks serving the Great Lakes region. By coordinating scientific observations, improving data accessibility, and supporting environmental decision-making, the organization plays a vital role in protecting and understanding one of the world's largest freshwater systems. ^{21) 22)}

As environmental challenges, climate variability, and resource management concerns continue to evolve, GLOS remains a key institution supporting scientific research, maritime safety, ecosystem stewardship, and public awareness throughout the Great Lakes basin. ^{23) 24)}
