IMI30: 2005 Beaufort Sea Survey

Healy Frozen In

In 2005, IMI-30 was mobilized on the icebreaker Healy to map the surface and shallow subsurface of the Beaufort Margin, north of Alaska. Unfortunately, ice conditions were too severe to launch the IMI-30 except for one fixed station and a four hour survey just north of Barrow, Alaska (the figure above shows the Healy frozen in ice, which lasted for four days of the survey). The first deployment on station (below) was sufficient to demonstrate that the new IMI-30 subbottom system was working as expected.

The subbottom data below shows reflectors consistent with those imaged by the Knudsen system that is hull-mounted on Healy.
