Personal Log
Whew…I made it to Unalaska. After an entire day of sitting on airplanes and running through airport terminals, I am finally here. I can’t believe how beautiful it is here. The surrounding mountains are a stunning green color and there have even been some sightings of blue sky between the normal grey clouds. I am also amazed at how warm it is. It almost got up to 60°F today, but I was told that the weather can change here pretty quickly. We have already heard of bad weather coming our way next week. The National Weather Service issued a Gale Warning with predictions of wind gusts of up to 50 knots and waves above 20 feet. I had better take my seasickness medications.
We don’t ship out until tomorrow, so we decided to take advantage of the nice weather and explore Unalaska. Unalaska is much bigger than I thought that it would be. It is a major international fishing port and is one of the larger cities in Alaska with about 4,000 residents. Life in Unalaska revolves around fishing. Most residents are either commercial fishermen, work in the processing facilities, support the fishermen through stores and other services, or work in the ship yards where the seafood is shipped to all parts of the world. The name of the harbor where all of this is going on might be familiar to you. It is called Dutch Harbor and is where the show “Deadliest Catch” is filmed about the commercial crab fishermen. Crab is not the only type of commercial seafood coming out of Dutch Harbor. Pollock, Cod, Halibut, Rock Sole, and Mackerel are just a few of the other commercial fisheries in Dutch Harbor.
For those of you interested in history, Dutch Harbor also has historical significance from World War II. Dutch Harbor was the only land in North America, besides Pearl Harbor, that was bombed by Japanese Zeros during World War II. In our exploring around the island today, we saw evidence of Armed Forces’ bunkers, Quonset huts, and barracks still visible amongst the green hills of Unalaska. The National Park System opened a WWII National Historic Area and Visitor Center in 2002 in Unalaska and I hope to have time to visit it either before or after my cruise.
What’s the best place to go on a beautiful, sunny day in Unalaska? The beach, of course. We didn’t go to the beach to get sun tans or to go for a swim. We went to check out the tide pools. I love tide pools! It is amazing how resilient the little creatures are that live in the tide pools. When the tide is in they are completely submerged under water and then six hours later they are above the water level when the tide goes out. To make life even harder, they are also smashed by huge waves crashing on them as the tide goes in and out. It is a tough life, but there was such a diversity of life that they must be pretty tough and have some helpful adaptations. As I explored amongst the rocks, I found sea anemones, barnacles, mussels, and lots of different types of seaweeds. On our way back to the van, we also found a stream leading back to a brackish lake and the salmon were running. They are amazing creatures to watch too. The amount of energy that they exert and the sacrifice that they make to reproduce is incredible.
Unfortunately we couldn’t spend our entire day exploring. The plan for the rest of the day is to get settled onboard the Dyson, have a science team meeting to discuss the science that we will be doing and the logistics associated with the different stations and sample sites, and have a safety meeting with the crew of Dyson to discuss life onboard the ship and emergency situations. I am so excited to go out to sea tomorrow and actually start fishing.
