Welcome!
It’s nearly time to embark on this adventure! I’ve always appreciated chances in life to explore and learn about different parts of the world. Recently I’ve enjoyed the book “One Earth, Two Worlds” by the Minnesota SCUBA diver Bill Mathies. I’m fascinated by the realm of underwater exploration. A large percentage of our planet has never even been seen by humans! NOAA’s hydrographic research vessels are in place around the world to map the ocean floor and promote safe navigation.
Science and Technology Log
I am Eric Koser and I live in southern Minnesota where I have worked with students learning about physics for 24 years. I teach at Mankato West High School, one of two mid-sized high schools in our river community of about 100,000 people. Mankato and North Mankato are the regional hub of south-central Minnesota. Our school district is home to about 9000 students K-12. Our community has particular strengths in manufacturing, education, and healthcare. Read more here at greatermankato.com!
I teach a variety of physics courses at West including AP Physics and Physics First at grade 9. I love to engage kids in learning physics by helping them to discover patterns and systems in nature. I really enjoy developing experiments and demonstrations to illustrate ideas. I also coach our YES! Team as a part of our Science Club here at West. Youth Eco Solutions is a program to support students to make positive energy and environmental based changes in their communities. These kids have tackled some big tasks – replacing styrofoam lunch trays with permanent trays, updating our building lighting’s efficiency, and systematically monitoring campus electrical usage.
Personal Log
My wife Erica and I have four kids that we love to support. They are currently ages 20, 18, 15, and 10 and always on the move. Our oldest, Josh, is an engineering and technical theater student at the U of MN. Our next, Zach, just graduated from high school and is rebuilding a small hobby farm and an 1800’s house to become his rural home. Ben is an avid photographer now working at a local photo studio shooting professionally for events. Meron is headed to fifth grade– she is our most social kid who loves being with her friends and our many pets here at home.
Our summers often involve many days at ‘the lake’, a place we enjoy in northern Minnesota with extended family. We love to fish, swim, kayak and explore the water there. As a SCUBA diver, I’ve begun to explore below the surface of the water as well.
This summer has also involved lots of construction on Zach’s farm as we bring a once gutted two-story house into a finished home.
In a few short days, I look forward to joining the NOAA Ship Rainier on a hydrographic survey of Lisianski Inlet on the SE coast of Alaska. I’ll meet up with the Ship in port at Sitka, Alaska.
The Rainier is a 231 foot long ship equipped with a variety of tools to digitally map the bottom of the ocean with the goal of updating and improving navigational charts. I look forward to meeting and working alongside the experts on Rainier while I learn everything I can about the important work that they do. I look forward to bringing questions and ideas to my students and community during and after this experience!
Questions!
The Rainier design specifications list a “draft” of 14.3 feet. What does this mean?
This ship displaces 1800 tons of water. What does this mean?
How could you determine the ‘footprint’ of the ship in the sea based on these two pieces of data? What is the average area of the footprint of this ship?
