Students from Carmel Middle School in Carmel, Ind., welcomed home Christine Hedge, a seventh-grade science teacher who spent six weeks in the Arctic Ocean on board the U.S. Coast Guard icebreaker Healy as part of a multi-year, multi-agency effort to collect seafloor mapping and oceanographic data along the North American Extended Continental Shelf.

"The discovery of this seamount is a prime example of how little we know about the Arctic Ocean," said retired NOAA Capt. Andy Armstrong, the mission's co-chief scientist and co-director of the NOAA-University of New Hampshire Joint Hydrographic Center. "Christine's keen observations allowed us to react in time to turn the ship and explore this important seafloor feature in closer detail."
