Assisted by a member of the Healy's crew, Stephane Plourde, of the Woods Hole Oceanographic Institution, fends off ice flows to retrieve the sampling net during the Western Shelf-Basin Interactions research cruise off Barrow, Alaska. Long hours and hard work are elements of any scientific research cruise.
