GLOS - The Great Lakes node of the national Integrated Ocean Observing System
The Great Lakes Observing System (GLOS) is an effort dedicated to providing wide internet access to real-time and historic data on the hydrology, biology, chemistry, geology and cultural resources of the Great Lakes, its interconnecting waterways and the St. Lawrence River. GLOS is a regional node of the U.S. Integrated Ocean Observing System (IOOS) initiative.Read more about GLOS

GLOS Awards St. Clair River Dye Study Contract
GLOS is pleased to announce a contract with Applied Science Inc. (ASI) to conduct a dye study on the St. Clair River. The purpose of the study is to calibrate a 3d hydrodynamic model developed for the St. Clair River, Lake St. Clair and the Detroit River. In August, dye releases will take place upstream of Marysville, MI and sampling will provide data on elements such as time of travel and dispersion over distance to help calibrate the model. The results will address critical needs for protecting drinking water supplies; support commercial and recreational navigation; improve responsiveness for search and rescue operations; and improve reactions and recovery from hazardous materials and oil spills within the waterway.
