NGS and the Center for Operational Oceanographic Products and Services (CO-OPS) cooperated to upgrade communications and power systems at four Continuously Operating Reference Station (CORS) sites co-located with water-level stations in the Great Lakes region. A common, accurate, and well-defined height reference datum for water levels is essential for coordinated international management across the Great Lakes. Since the region is prone to postglacial uplift, understanding height and water-level changes over time is crucial for safe navigation and other activities.
