The blow…a giant, audible exhale. Heads turned to look, hoping for a glance at the world’s second largest mammal, the fin whale. A single fin whale can be up to 85 feet long and weigh up to 160,000 pounds. At Cornwallis Island, guests aboard National Geographic Resolution had a once in a lifetime experience, the thrill and awe-inspiring delight of a super pod of fin whales. Audible and visible blows in every direction as far as the eye could see sent us all into sensory overload. The water surrounding the ship was filled with gentoo and chinstrap penguins, numerous seabirds, and an estimated 200 fin whales.  The visual blow, the audible sound, the overloaded sensory experience…a day we will never forget.
