Real-time ice and snow monitoring

SIMB3 enhances your observational capabilities with ice thickness, growth, melt, and temperature data on demand. 

How it works

SIMB3 measures mass balance, snow accumulation, and temperature of sea ice, pond ice, or lake ice anywhere in the world.

Every hour, data are transmitted and available online immediately

Why Sea Ice Mass Balance Buoy 3?

Water icon

Collect data in summer

High-precision sonic rangefinders directly measure ice and snow position even when the ice is warm and melting.

Sun icon

Open water deployable

Waterproof and buoyant, SIMB3 is both deployable and operable in open water and seasonal ice.

Clock icon

Set it and forget it

Install SIMB3 in less than 30 minutes to collect a year's worth of data.

Time-Series Monitoring

SIMB3 enables year-long observations of ice melt, growth, and temperature profile that are impractical or impossible to collect by other means. Whether you’re conducting climate research or monitoring ice roads, SIMB3 stretches your data collection capabilities and dollars by automating routine observation.

Real-Time Connected

We believe that data is better when it’s in your hands quickly. From our data dashboard, you can view the data your SIMB3s collect immediately after they collect it. Current conditions, historical measurements, and instrument information are available within 5 minutes of transmission from anywhere in the world with an internet connection.

Performance Optimized

Observing the world's harshest environments is tough enough. SIMB3 was born out of the frustration of faulty and inconsistent equipment making a difficult job even harder. From deployment to recovery, we’ve optimized SIMB3 to make your life easier and ensure your research goals are met every time.

Testimonials

Don Perovich headshot
"The SIMB3 is a central component of our research program. It provides enhanced capabilities for sea ice mass balance measurements in a package that is easier to ship, easier to install, more reliable and less expensive than previous models. Data from SIMB3s are automatically posted on the web within minutes making it easy to track ice temperature and thickness at multiple locations in the polar oceans"
