Water Level, Wave and Webcam (WWW) Network

IOOS Regional Associations, including MARACOOS, are deploying networks of low-cost water level sensors, wave buoys, and webcams to fill critical gaps in coastal hazard data. These systems provide real-time, hyper-local information to help coastal communities prepare for and respond to flooding, rip currents, and other coastal hazards. By partnering with local residents, decision-makers, and federal agencies, and integrating with existing national networks, this collaborative effort ensures access to vital ocean data to strengthen community safety.

WWW Network Goals:

The data collected from these sensors will be visualized through OceansMap providing clear, real-time insights on water levels, waves, and coastal conditions.

Decision-makers across the Mid-Atlantic—including emergency managers, planners, and municipal leaders—will use these tools to inform flood forecasting, emergency response, infrastructure planning, and public safety communications, ensuring timely and locally relevant decision support.

improve community safety

Deliver near-real-time, local information on flooding, waves, and coastal hazards to help keep people and property safe.

LOCALIZED DECISION-MAKING

Provide accessible data tools that support smarter planning and faster response during coastal emergencies.

connect people with ocean data

Make ocean and coastal information easy to understand, use, and trust—whether you’re a resident, a fisherman, a business owner, or an emergency manager.

BUILD PARTNERSHIPS FOR STRONGER COASTS

Work hand-in-hand with local communities, scientists, and government partners to create solutions that meet real-world needs.

Water Level Sensors

Expanding data access for flood risk, emergency response & public safety

Installed at strategic locations like bridges, marinas, and tidal creeks, low-cost water level sensors collect data every 15 minutes. This hyperlocal information helps track tidal flooding and storm surge in real-time, improve emergency response and planning, and support public safety and coastal decision-making.

Wave Sensors

Provide critical data for maritime navigation, beach safety and wave-driven flooding predictions during storms.

Wave buoys, whether floating or moored offshore, deliver hourly updates on wave height, wave period and wave direction, helping emergency managers make informed decisions during storms.

Webcams

Webcams enhance situational awareness and support alerts for coastal hazards and public safety

Webcams offer continuous visual observation of shoreline changes, rip current activity and surf zone dynamics. MARACOOS webcams are part of the larger WebCOOS web camera network and the data is also available in OceansMap.
