Today is my last full day on the Fairweather and tomorrow I will be departing when we dock in Seward, Alaska. I could not have asked for a better final day! But first, yesterday I went out on a launch to survey a near shore polygon. Let me explain. A project is the survey area that the Fairweather is tasked with, in this case, Sitkinak Strait. The project is then broken down into sheets which are areas to cover each day. The sheets are divided into areas called polygons and each day, the launches will be tasked with surveying specific polygons. Yesterday, our polygon was very close to shore. This was difficult because the rocks and vegetation could be hazards. The surveyor in charge, Pat, had to be in constant communication with our launch driver Rick so that they could maneuver safely as we used the multi-beam sonar to scan the area. Since we were so close to shore I kept a steady scan of the landscape for bears. I did this not because we were too close and in danger from a bear, but just because I wanted to see one. We accomplished our task and finished our polygons and did not see a bear, but we did see a brown fox walking along the black sand beach!
Now, for today. I did tide observations in Japanese Bay and as we were setting up I snapped this picture of a bald eagle in flight with prey in its claws, possibly some kind of rodent since it appears to have a tail! (Click on the picture to see it better) We took tide observations which were interesting today for three reasons. First, the tide level was totally different than it was last week when I took measurements. If you look at the two pictures below, one from June 28th and the other from today, July 2nd, you can see how much lower the tide is. Look at how close to the staff I was today and how far away last week. The water actually went lower than the tide staff today! Earth Science is so interesting.
Now, the second and third reason I found tide observations so cool today did not have anything to do with the tides. It was all about the animals. And no, it did not involve a bear. Second reason it was interesting was the bald eagle in the picture above. I just love how I was able to capture it with its wings spread so majestically. It has a nest in the tree that it was flying into. Since it was carrying lunch in its claws, I thought maybe it was taking food to the nest to feed baby eagles. What do you think? Now, third reason tide observations in Japanese Bay were so cool today was because of swimming deer! I know I should have led with that but I knew it would be pretty awesome to put a swimming deer video into the middle of my blog. The video is a little jumpy because I was fighting the waves in a small boat called a skiff. Check out the video!Before I thought to start videotaping I was able to capture a picture of them swimming!
Scientist of the Day Today I would like you to meet Shauna Glasser, a First Assistant Engineer for NOAA who is currently aboard the Fairweather. It’s old hat for Shauna to travel wherever the Fairweather may take her. Growing up, she moved so many times that college was the first school she went to for four years in a row! Even though she moved often she still managed to be successful in her academics. She received a BA in Marine Engineering Technology from California Maritime Academy but it was by chance that she even enrolled there. As a senior in high school she received a postcard in the mail from this college.
Knowing nothing about the school, Shauna decided to visit the school for a week long introduction program to see their campus and curriculum. She knew she wanted to be a marine biologist and she enrolled. However, before college began, her math teacher from high school recommended she take a summer class in chemical engineering. Shauna always excelled in math and she really liked the engineering, but not so much the chemical side. She soon switched paths from marine biology and became a marine engineering major.
Shauna has been with NOAA for five years and has worked her way up in the job. As first assistant engineer she is the person on the ship directly under the chief engineer. There are eight people who report under first assistant engineer. The engineers do all the maintenance on the ship and they keep it running. Shauna says that this is a job that is in high demand. The Fairweather, along with two other ships in the fleet, will actually be docked at port starting July 7th because they are in need of more engineers aboard. The ships can’t run without them! This young engineer has risen to a leadership role in her field and sees being a chief in her future. Shauna says, “Go for it! Ask questions, be yourself, think smart, and you can do it!”
My day today is ending just as magical as it began with several more animal sightings. We are underway to Seward, Alaska where I will say goodbye to the wonderful crew of the Fairweather. As we got underway we had a fire drill and then a little while later, an abandon ship drill. As the crew at my drill station were standing on the port side of the ship wearing our life jackets, hats, and in possession of our survival suits, a pod of orcas swam by spouting from their blowholes. They play and blow as they pass by our ship. Then, after dinner I am working on this blog and take a break and go to the bridge to see what’s going on. There were pods of orcas to the port side and humpback whales a mile north of us. The humpbacks were spouting and breaching. I have an out of focus picture of a whale going straight up in the air. It looks like it’s pirouetting. The crew on the bridge said that this was a large sighting of whales and everyone was excited.
I begin looking at the equipment on the bridge and asking questions when I was asked if I would like to steer the ship. Nervously I said yes. They explained that it was currently on a type of ship auto pilot which they would turn off and I would take the helm, similar to a steering wheel on a car, and I would be in control of the ship’s path. Jim Klapchuk, an Able Seaman on the Fairweather, showed me what to do. I would be at the helm and would continue in the correct direction by looking at my gyroscopic compass and my rudder angle indicator. The gyroscopic compass would tell me my heading, which was 030° which would keep me going north-east. The rudder angle indicator would move every time I moved the wheel because turning the wheel turned the rudder and the rudder changes the course of the ship. Keeping this lesson in mind, they turned off the auto pilot and I was steering the 231 foot ship on a heading for Seward! I kept constantly looking at the numbers and trying to keep it at exactly 030°. After a short while, the boat felt like it was swaying a bit so I gave the helm back to Jim and they set it back to auto. What a way to end my science adventure!
A warm thank you to all the crew aboard the Fairweather. I have learned so much and will take back to my classroom a new excitement along with tons of science. Terms like hydrographic, surveys, hydrographer, polygon, launch, CTD, gyroscopic compass, swells, tides, charts, cartographer and many more will be introduced. I have also enjoyed getting to know you and hearing about your lives. You are a talented group. And I learned to play cribbage – thanks Tim and Charlie!
Question: But first, an answer to the last plant or animal poll. It appears that all of you know what a jellyfish looks like because you voted animal. Thanks for voting and thanks for following my blog. There are a lot of jellyfish here in the Gulf of Alaska and I will leave you with a few of my favorite shots. It’s amazing how each one looks so different. Which is your favorite? Vote in the poll below!
