Adopt-A-Float
The MERMAID App
Free · Designed for iPad
Adopt-A-Float allows users to access trajectory metadata and state-of-health parameters of the EarthScope-Oceans MERMAID fleet. MERMAID, short for Mobile Earthquake Recording in Marine Areas by Independent Divers, is a long-lived drifting autonomous float equipped with a hydrophone capable of recording acoustic waveforms generated by distant earthquakes. Most earthquakes occur at or near plate boundaries, yet most seismic monitoring stations are on dry land. Deployed but not recovered, telemetering data in near-real-time, MERMAIDs are uniquely positioned as a low-cost alternative for geophysical and environmental oceanic data collection. Diving down to a typical parking depth of 1500 m below the ocean surface, they passively drift with the ocean currents, recording the ambient acoustic wavefield, identifying earthquake signals, and surfacing to report those, on average every 4-7 days with the current settings, which are expected to give them a five-year life span. When at the surface, MERMAID collects GPS location and time information and communicates with the IRIDIUM satellite constellation using RUDICS.
Using this iOS app you can:
View the current location of all MERMAID instruments
View their most recent trajectories and obtain information about ocean depth
View instrumental metadata such as battery level and instrument pressure readings
Identify the instruments by name and by operating institution

MERMAID was designed by scientists and engineers and is now built by OSEAN SAS (www.osean.fr), from which it is commercially available.
EarthScope-Oceans (www.earthscopeoceans.org) is an organization founded by a multidisciplinary group of geoscientists who are coordinating efforts to create a global network of sensors that monitor the Earth from within the oceanic environment. As other organizations are doing for the land-based seismological communities today, EarthScope-Oceans shepherds national projects into the international arena where globally relevant, applicable, and mutually agreed-upon decisions can be made on instrument development, science objectives, data management, and outreach.
What’s New in This Version:
Enhanced Real-Time Data Integration: Improved initial buoy data retrieval with seamless caching, ensuring faster subsequent loads and a smoother tracking experience.
New Loading Pop-Up: Added a friendly pop-up to inform users of initial data download times, ensuring clear communication during setup.
Improved User Interface: Refined the map-based interface with smoother polylines for buoy paths, better performance, and more interactive visualizations.
Optimized Dark Mode: Updated the About View for better contrast and readability in dark mode, making the app visually appealing in all settings.
Minor Bug Fixes: Addressed stability issues and enhanced performance for a more reliable experience.
