Science and Technology Log
Last night we spent the entire night steaming south west down the Aleutian island chain, through the Unimak pass to the western side of the islands and past Dutch Harbor. Tonight we plan on picking up 4 moorings at Amukta pass and no new buoys will be deployed. The decision to move to the west side of the chain was made due to a small storm with 5 knot winds on the east side of the chain. If the weather improves we will move back over to the east side of the chain in a day or 2.
Last night I was awoken at 2:00 AM by some large waves that were tossing the boat (and me) back and forth. I kept thinking…”this boat has no centerboard” and “should I wake
up my roommate?” In the morning I discovered that my roommate was already awake and…this boat can take a lot more than what we saw last night. All of the tests are done with the centerboard up so we are still well within the limits of this boat. This journey has been an invaluable experience but I am very much looking forward to arriving in Dutch Harbor and seeing the wild horses that live there.
Question of the day: What are the factors that effect the formation of waves? How do the weather patterns differ between the Gulf of Alaska and the Bearing Sea
