Growlers, Pancakes, and Bergy Bits
June 6, Tuesday
The engines roared. The rotor blades whirred. The butterflies in my stomach did cartwheels and handsprings. Here I was, strapped into my 5-point harness, about to lift off in a helicopter over the Arctic Ocean! Look out below!
How did Janice and I end up flying aboard a U.S. Coast Guard HH65 Dolphin?
Earlier that day, the Healy finally reached our destination - the ice! I couldn't believe how beautiful it was. Chunks of ice floated alongside the ship like dozens of enormous sugar cubes. A huge iceberg off the starboard side looked like an enchanted castle. We were in the frozen north at last!
It was only a matter of minutes before the Healy left the ice behind and sailed back into the open ocean. I asked Bob Whritner, a meteorologist with the Scripps Oceanographic Institute, what had happened. Bob explained that we had just passed through an ice field that had broken off from the solid pack ice. He assured me that we would find more ice as we traveled towards the coast of Labrador.
Every winter, new ice forms as the surface of the ocean freezes over. Depending on how cold it gets and how long it stays cold, the polar ice cap in the Arctic can double in size! In the summer, the ice cap begins to shrink as temperatures rise. Chunks of ice break off from the edge of the ice field and begin to drift with the currents. They crash into each other as they drift, breaking into even smaller pieces until they finally melt. This what we saw in the ice field.
Icebergs are different than sea ice. Once part of glaciers or ice caps on land, icebergs break off in huge chunks. Their appearance is deceptive. Even though they tower out of the water like giant ghost ships, most of their mass is hidden below the surface.
The Healy scientists weren't interested in icebergs. They were looking for a place where sea ice covered at least 70% of the surface of the water. To find it, the scientists and Captain Garrett first consulted today's satellite map of the ice. Once they had chosen a spot, they decided to send a helicopter to check it out.
So here we were, Janice and I, flying over the ocean in search of more ice. After lift off, the helicopter circled the Healy several times. Then we rose 1,000 feet into the air and headed north, flying at a speed of 150 miles per hour!
The Arctic Ocean was incredibly beautiful from the air. Patches of ice formed a giant jigsaw puzzle that stretched as far as the horizon. Turquoise water swirled at the base of giant icebergs. It was the most awesome sight I had ever seen!
