Coast Guard MH-60 Jayhawk and MH-65 Dolphin helicopters prepare for take-off from the flight line at Air Station Kodiak, Alaska, Aug. 14, 2014. The air station provides primary support at this time of year by deploying aircraft and crews to forward operating locations such as Barrow, Alaska for Operation Arctic Shield, to stand the watch over areas of the vast arctic that see increased traffic during the summer months.
