The Great Lakes Nearshore Buoy Network (formerly UGLOS) is a unique public-private partnership that provides real-time and historic data from across the Great Lakes. The Great Lakes Observing System (GLOS) brings together and supports partners from across sectors to provide valuable coastal observation data to the public. Buoy data gives users a glimpse of current lake conditions by reporting meteorological and oceanographic conditions, including physical data, e.g., wind (speed, direction, gusts), waves (height, period, direction), and water temperature, as well as selected bio-chemical data, phosphorous, chlorophyll a, and related remote sensing activities.

Nearshore buoys report all parameters to GLOS and NDBC throughout the navigation season. Data is reported every ten minutes, allowing users to track the extremely rapid changes that occur in nearshore waters. Buoy pages allow users to view and download real-time and historical data and visualize trends. Other features include Buoy Cams and text alerts from the station or buoy of choice.

Many users rely on buoy data, including coastal municipalities whose economy depends upon up to date and accurate meteorological and oceanographic information, municipal drinking water intakes, private coastal and water quality consulting firms, nuclear power generation facilities, commercial boating interests, Native communities, universities and government agencies.

The Great Lakes Nearshore Buoy Network partners include:

NOAA, National Data Buoy Center (NDBC), National Park Service (NPS), Great Lakes Research Center of Michigan Technological University (MTU-GLRC), the Michigan Tech Research Institute (MTRI), University of Michigan (UM), University of Michigan's Biological Station (UM-CILER), Northwestern Michigan College, Northern Michigan University (NMU), United States Coast Guard, US Army Corps of Engineers, LimnoTech Inc., Cook Nuclear Plant, Indiana Michigan Power, City of South Haven, Van Buren County, Entergy - Palisades Nuclear Plant, Illinois-Indiana Sea Grant (IISG), Purdue University, Enbridge, and others.

This network of partners and observing stations continues to grow annually, due primarily to increased public and commercial interests. For more information on how you can get involved, please contact
