Personal Log
A lot has to happen before the first pollock net is even cast. First the crew, including officers, engineers, deckhands and scientists must meet the NOAA Ship Oscar Dyson in Dutch Harbor, Alaska. If you are traveling from Dover, NH the trip is over 4,200 miles or about โ circumference of the Earth.ย Dutch is a remote community nestled within an archipelago of volcanic islands which formed approximately 60 million years ago where the Pacific tectonic plate forces under the North American Plate. This meetup takes planning, time, and sometimes patience as the Aleutian Islands are often windy and foggy, making air travel from mainland Alaska unpredictable. Read more information about NOAA Ocean Exploration’s geological studies in Alaskaโs Aleutian Islands.
Once everyone is onboard, NOAA officers pilot Oscar Dyson out of Dutch Harbor and the Aleutian Islands into the Bering Sea. Check out this map of the Summer Acoustic Pollock Survey. The black line represents the path of the summer pollock survey which takes place over the course of 3 separate trips. I am traveling on the final survey of the summer, so it’s the farthest western side of the Bering Sea pollock survey that needs to be completed, the black line on the map not yet highlighted. It takes over a day to get out to this part of the ocean, but the crew and scientist have lots to do to get ready for the trawl during the trip.
Science and Technology Log
Running a science research center in a remote part of the ocean comes with โboatloadsโ of STEM challenges. Without the ability to order things online, go to a local home improvement store, or buy specialized parts off the shelf, the scientists and crew need to create their own solutions to the challenges that arise. Just like a STEM makerspace, NOAA Ship Oscar Dyson is well stocked with a tool workshop, 3D printer, and rolls and rolls of duct tape. Here are some of the amazing inventions from the super simple to the more complex that were designed onboard the ship.
Pegboard Modifications: On the high sea, wave and wind motion can be powerful, traditional pegboard hooks are just not going to cut it. These bright-colored accessories were custom designed and 3D printed on board to secure tools in their place. The calipers proved a bit trickier due to their asymmetrical design.
Underwater Camera: This underwater camera was created because the science team needed more information about what is going on beneath the oceanโs surface. To keep it from crashing into the ocean floor and becoming damaged, it was designed with sensors that move the robotic cameras up and down as it detects obstacles.
Krill Scan: Needing a way to get tiny organisms measured and recorded, NOAA scientists came up with this 3D printed gadget designed to fit on the ship’s scanner. Soon after a trawl is pulled in, a pocket net (a small net used to recapture small fish that escape the larger net) is emptied and krill samples are sorted into their own square within the grid. Images are scanned and recorded while the creatures are still fresh. Marking around the squares allow scientists to calculate krill size easily and the boxes keep specimens from clumping together.
Microscope Camera Stand:This tool was designed and 3D printed to hold a cell phone in place to capture images of objects under the microscope.
Ichthystick: When fish come aboard, data on their length needs to be quickly calculated. The motion of the moving boat, and the slipperiness of a squirming fish make using traditional tools such as rulers and tape measures cumbersome and impractical. Meet the Ichthystick. This nifty device was designed by a NOAA scientist on Oscar Dyson for just these situations. Simply put the fish on the measuring board,ย set the magnetic marker at the fork of the fishโs tail and it instantly gives the fishโs length on screen. It can also toss the data right into a data collecting program. Look up the prefix โIchthyโ and find out why I think the name โIchthystickโ is such a perfect name for a device designed for keeping tabs on native Alaskan Pollock who often end up in your freezer.
Try It on Dry Land
STEM Scholars donโt just gripe about problems, they create solutions to these challenges. Think about things around you that donโt work quite right or annoy you as you try to complete your work. Design a device that helps you solve a reccuring challenge in your environment. Diagram your idea, orย build a prototype to see if it works.
Here are some common middle school challenges or think up your own:
- Your pencil frequently rolls of your desk
- Your pet leaves muddy footprints across the floor
- You can never find your sports gear when it’s time to leave
- You canโt reach something you want on a top shelf
- Your backpack is not keeping you organized
