Water Levels, Waves & Webcams (WWW Network)

Back to Projects

MARACOOS, along with other IOOS Regional Associations, are deploying networks of low-cost water level sensors, wave buoys, and webcams to fill critical gaps in coastal hazard data. These systems provide near-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 at the local and state levels, and federal agencies—and integrating with the existing national WebCOOS network—this collaborative effort ensures access to vital ocean data to strengthen community safety.

WWW Network Goals

Enhance Community Safety

Deliver near real-time information on flooding, waves, and coastal hazards which can include rip currents, dangerous shore breaks, high waves, storms, flooding, marine life interactions, and other environmental risks. Providing this data and information can help communities protect people, property, and infrastructure during changing coastal conditions.

Support Local Decision-Making

Provide easy-to-use data tools that empower emergency managers, planners, and local leaders to make informed, timely decisions for flood forecasting, emergency response, and coastal resilience.

Connect People with Ocean Data

Visualize sensor data through OceansMap, turning complex ocean observations into clear, trustworthy insights on water levels, waves, and shoreline conditions—for residents, fishers, businesses, and decision-makers alike.

Build Partnerships for Stronger Coasts

Collaborate with communities, scientists, and government agencies to co-develop solutions that address real-world coastal challenges and strengthen regional preparedness.

WWW Webinar Series

Watch our summer 2025 webinar series recordings to learn more about the WWW Network and explore the latest options with OceansMap and our OceansMap Insights, broken down by state (Delaware, Maryland, New York & New Jersey, and Virginia).

If you don’t have time to watch the entire webinar, we’ve broken each session into bite-sized segments so you can dive into the topics that matter most to you, linked below each full-length video.
