Robotic Oceanographer

Icefin is a hybrid remote or autonomous underwater vehicle (ROV/AUV) that is both modular and field-portable; it is essentially a small, long-range, deep-water, under-ice, robotic oceanographer.

Icefin lab

Primary Capability

Icefin aims to characterize sub-ice environments using sonar, chemical, and biological sensors to explore ice and water conditions around and beneath ice shelves.

Our Goal

Through Icefin, we’re able to simultaneously explore Earth and develop the technology we need to one day explore other oceans in our solar system.

What's great about Icefin

Custom Missions

Icefin’s modules can be swapped or rotated for each mission, to point sensors either up at overhead ice or down towards the seafloor.

Modular Design

Icefin's modular design offers increased mission flexibility, capability, and operational simplicity, relative to traditional AUV/ROVs.

Slim Profile

Icefin is uniquely designed to fit through narrow ice shelf boreholes while still carrying a full suite of oceanographic sensors​

Icefin was developed first as a prototype under PI Schmidt’s startup funds in the College of Science at Georgia Tech. Since 2016, Icefin has been fully developed by the Planetary Habitability and Technology team featured on this page. Funds for development of the vehicle have come from NASA grants lead by Schmidt and field research with the vehicle has been funded by NASA, NSF, Antarctica New Zealand and the Marsden program.
