breakfast—they were high in fat and carbohydrates, two sources of energy I would need for the swim. Then I started through the hallway to my cabin, where many of the Orlova’s passengers were waiting, eager to find out if I was going to swim. They wished me luck and said they would wait for me at the finish. I stopped by Dan’s cabin to ask him if he would jump into the water with me at the end of the swim. He was already in his dry suit, prepared to go. Everyone was doing what we had practiced. All I could do was to go back to my room and wait. Gabriella came in to take a core temperature; it was up to 100.4 degrees. Knowing I was venturing into unknown waters, I must have psyched myself up so much that I increased my body temperature. Gabriella left me alone while I put on my swimsuit and sweats. I rubbed sunscreen on my face, but not on my arms or legs; it could make my skin slippery, and if my crew needed me to get out of the water quickly, that would create a problem. The night before, three of the crew had spotted a pod of eight killer whales swimming into the Gerlache Strait. They hadn’t been moving fast. I hoped they were still north of us.

I stared out the window at the brown crescent-shaped beach. There were snow-covered hills directly above the beach, and massive glaciers on either side. I picked out landmarks, places I could aim for, so I’d know if I was on or off course.

Dr. Block caught me at the top of the stairs, just before we stepped out the door and onto the ramp, and asked if I would sit down on a step so he could trace two veins on my hands with a blue Magic Marker. It was just a precaution, he said, in case I needed emergency assistance; this way he would easily be able to find a vein to start an IV. I gave him my right hand and watched him draw the blue lines for the television camera. It gave me the creeps. Why did he have to do this now, right before I swam? Didn’t he realize this kind of stuff psychs people out? I know the swim is dangerous, but he could have done this hours ago, not just before I swam. Get over it, I told myself. Shake it off. Take a deep breath. Refocus. Take another breath. Good. Now think about the swim. I smiled. I’m so ready for this.

Walking to the door, I peeked out and felt a blast of icy wind hit my face from the northwest. It was blowing in off the glaciers in gusts to twenty-five knots, and the air temperature was thirty-two degrees. I felt the hair rising on my arms and my jaw tighten to suppress a shiver. I was much more nervous than I had been during my first swim. I had greater expectations of myself now. I wanted to swim the first Antarctic mile, and I knew I would be very disappointed if I didn’t succeed.

I stared across the icy water at Neko Harbor’s beach and felt excitement building within me. Quickly before I could lose my chance, I pulled off my sweat suit and shoes and stuck them in a corner of the ship, climbed down the gangway, sat on the platform, and dangled my feet in the water. Surprisingly, it didn’t feel any colder than it had two days before. I didn’t realize then that the nerves on my skin’s surface had been damaged from the first swim. I didn’t know that the nerves that signaled danger weren’t firing. I wasn’t aware that my first line of defense was gone. I had no idea that prolonged exposure in thirty-two-degree water could cause permanent nerve and muscle damage. And I didn’t know then that when an untrained person is immersed in water colder than forty degrees, their nerves are cooled down so they can’t fire at the neuromuscular level. After only seven or eight minutes the person’s body seizes up and they can’t move. It was a good thing I didn’t know any of this. All I knew was that I was ready. I took a deep breath, leaned back, and threw myself forward into the thirty-two-degree water.

When I hit the water, I went all the way under. I hadn’t intended to do that; I hadn’t wanted to immerse my head, which could over-stimulate my vagus nerve and cause my heart to stop beating. Dog-paddling as quickly as I could, I popped up in the water, gasping
