Antarctica Journal 3.7.09 (sorry about the formatting - I typed this in Word)

The Drake Passage – Day 1

The ship was rolling pretty strongly during the night. At one point, there was a series of little crashes, as everything that wasn’t battened down flew across the room. When I got up to go to the bathroom, I mistimed it and got up when the ship was rolling towards the bathroom, so I hurtled right past it and hit the cabin door. Luckily, I didn’t wake my roommate.

After breakfast, we had two mandatory lectures. The first was on the Antarctica Treaty1 and the second was about zodiac safety2. In the hour before lunch, I did some bird watching, took some pictures (I tried to take pictures that showed the rocking of the ship) and took a nap.

At lunch, I had a salad from the salad bar, wild rice soup, chef salad and pound cake drizzled with dulce de leche and a scoop of vanilla ice-cream. During the announcements, we were told that the photo class was starting at 1:45 and would last until 3. The next announcement was that the gift shop would be opening at 2 for an hour. There were lectures at 3 and 5, as well, so I was going to miss the shopping hour and I’d already found several items in the catalog that I wanted to buy. The photo class3 was over twice as large as we’d been told (“limited to 10”) and a lot of time was spent on individual instruction for people who didn’t know how their cameras worked. It took 20 minutes just to get through ISO, so, when the instructor, Ellen, started helping people figure out their flashes, I ran across the ship to the gift shop and picked up the fleece I’d noticed in the catalog.

Ellen was still working on flash, so I didn’t miss anything. I’m more than a little disappointed about how the class started. There are too many people (especially since I only signed up because it was going to be a 10-person class) and we covered only ¼ of the material she’d expected to teach in a 2-hour session. We’re also going to have to fight over who gets to sit in her zodiac during the excursions.

The 3pm lecture was about the birds of Antarctica4 and then we got fresh, hot peanut-butter cookies at Afternoon Tea. The 5 pm lecture was about Shackleton’s 1914 expedition, but I didn’t learn anything that I hadn’t already known. More bird-watching until Happy Hour, but, by the time I got there, the lounge and bar were full, so I did some prep work on my running shoes (we had to clean them thoroughly before stepping foot on Antarctica) and rested in my room.

Dinner started with salad bar and pumpkin soup, which was pretty good. I had the pork entrée and dessert was a total disappointment – rhubarb tart. The ship was really rocking and rolling and the portholes were getting splashed. I tried to get pictures and vide, but wasn’t very successful. Ellen saw me taking pictures and asked me what I thought of the class. So I told her. She asked me to sit down and tried to show me my camera’s settings in more detail, but the battery died at that moment (3rd time in 3 days!), so she showed me on my old Casio. Not that it did much good. After dinner I was going to hang out in the lounge, but it was really crowded and noisy, so, after a few rounds of Trivial Pursuit questions, I went to bed.
