Every summer, NOAA GLERL scientists travel far and wide across the Great Lakes region to study the biological, chemical, and physical properties of these amazing lakes. A portion of this fieldwork contributes to a larger project called the Cooperative Science and Monitoring Initiative – or CSMI – which helps us take a deeper dive into studying a different Great Lake each year. 2022 was Lake Huron’s turn to shine, and GLERL’s efforts focused on benthic and spatial surveys in Thunder Bay and Saginaw Bay.
