Oceanographic data collected from non-federal stations assembled by the Great Lakes Observing System (GLOS)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:12 AM | Dataset Last Updated: July 12, 2026 at 12:00 AM
This dataset contains oceanographic and surface meteorological data collected from non-Federal stations throughout the Great Lakes region of the United States. The data is predominantly long time series at fixed moorings and buoys with a variety of instruments including CTDs, fluorometers, oxygen sensors, optical turbidity sensors, pH sensors, meteorological sensors, and water quality sensors. The data files are in netCDF format, following the Climate and Forecast metadata convention (CF) and the Attribute Convention for Data Discovery (ACDD). Great Lakes Observing System (GLOS), which assembles data from sub-regional coastal and ocean observing systems, submitted the data to NCEI as part of the Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program.
