All About the Healy!

The USCGC Healy is the largest non-nuclear ice breaker in the world.  It can break ice as thick at 4 1/2 feet continuously at a speed of three knots.  According to the Healy’s website, the ship can accommodate up to 50 scientists and about 50-60 enlisted as well as officers at one time.  It can also work at a temperatures as low as -50 degree F.  No other ship will due in the challenging environment of the Arctic Ocean.

While onboard, USGS Ocean Acidification Project Chief Lisa Robbins had the chance to drive the Healy. She sent back some photos of the helm of the boat. The wheel was quite small for such a large ship.
