On June 25, 2011, a tug boat headed back to Dutch Harbor, Alaska, after guiding the U.S. Coast Guard Cutter Healy away from port as part of the ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment."

On June 25, 2011, a tug boat headed back to Dutch Harbor, Alaska, after guiding the U.S. Coast Guard Cutter Healy away from port as part of the ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment."
Stanford University researcher Kevin Arrigo led the ICESCAPE team as chief scientist.
ICESCAPE scientists watched from the deck of the Healy as it cut a path through thick multiyear ice on July 6, 2011. Cutting the path is key for getting researchers to remote research sites amid the sea ice.
The sea ice atop the Arctic Ocean can—as shown in this photograph from July 12, 2011—is dotted with fresh-water melt ponds and looks like Swiss cheese or a bright coastal wetland. Here, crew from the Healy retrieve a canister dropped by parachute from a C-130, which brought supplies for some mid-mission fixes.
Teams of scientists set up equipment on sea ice not far from the Healy in the Chukchi Sea on July 4, 2010, where they spent the day collecting data.
On July 19, 2011, Zachary Brown of Stanford University sipped freshwater from a melt pond on sea ice in the Arctic Ocean.
Sunsets started to tease the Arctic horizon as scientists on board the Healy headed south in the Chukchi Sea during the final days collecting ocean data for the 2011 ICESCAPE mission.
On July 25, 2011, Karen Frey of Clark University, scoped out the packing yet to be done in one of the labs aboard the Healy during the final week of the ICESCAPE mission.
On July 13, 2011, scientists and crew of the Healy lined up for a rare photo op to "tow" the icebreaker ship through sea ice in the Arctic Ocean, led by Captain Beverly Havlik.
On June 28, 2011, Holley Kelly, a teacher from Farragut High School, helped retrieve a data collection instrument from the Bering Strait, east of the Diomede Islands.
