Why Sea Ice Mass Balance Buoy 3?

Collect data in summer

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

Open water deployable

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

Set it and forget it

Install withouth tools in less than 30 min for fully-autonomous, 4-season operation.

Feature-Packed & De-Risked

Building equipment that withstands the test of time in the world's harshest environment is no easy feat. SIMB3 is the result of years of R&D, and now we've packed it with even more features to help you accomplish your research goals.

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.

Testimonials

"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"
