Seagull COAST

A New Mobile App for Great Lakes Coastal Safety

Seagull Coast is a new mobile application designed to help people make safer decisions when planning recreation in Great Lakes coastal areas.

With a user-centered design process that included workshops with recreational users and domain experts, surveys for requirements gathering, and multiple rounds of low-fidelity and high-fidelity design iterations, the app’s structure is informed by- and built for- the user. 

Seagull Coast offers:

  • Clear, easy-to-understand coastal safety information for recreational planning
  • Identification of unsafe lake conditions that may impact activities such as boating, swimming, paddling, and shoreline recreation
  • A mobile experience designed specifically for on-the-go decision-making
  • Science-based data translated into actionable insights for everyday users

The app was launched in July of 2026. Download and test the free app for yourself!

Seagull—a powerful, cloud-based platform for Great Lakes data and information

GLOS built Seagull to help connect people to the water like never before. A powerful, cloud-based platform, Seagull re-imagines how connected data becomes information and insights in peoples’ hands.

Seagull enables observers to:

  • Understand live lake conditions and make informed decisions
  • Contextualize information using search, a beautiful map, and simple visualizations
  • Easily connect a device or data source and share it with thousands of other people
  • Track their buoy, sensor, or other observing platform in real-time

Legacy Apps

Legacy applications have been phased out and decommissioned as the state-of-the-art platform Seagull has grown and developed advanced functionality.

Included in the decommissions:

  • GL Buoys – Retired in 2022, with data and buoy integrations now on Seagull
  • Huron-to-Erie Corridor Spill Tracking Tool, or HECSpill. We look forward to integrating features of the HECSpill tool into the Seagull platform in the future.
  • Great Lakes Geospatial Metadata Catalog
