Welcome to my blog! My name is Taylor Planz, and I am so honored to be a Teacher at Sea this season! My passions in life besides education are my family, my cats, the mountains, and, of course, the ocean! In college I studied Oceanography and conducted undergraduate research in Chemical Oceanography where I explored phosphate dynamics in estuarine sediments. I went on multiple afternoon research cruises as part of my undergraduate degree, but I have never been on a ship overnight before now. I married my husband Derrick in 2014 on the beach, a childhood dream of mine. We got married on the Gulf of Mexico in Destin, Florida.

In the fall I will be teaching Physical Science and Forensic Science to juniors and seniors at Harlem High School in rural Harlem, GA. In the past, I taught middle school science and this year will be my first year in a high school classroom. I am excited to teach a new age group this fall as there are many big decisions students must make during these critical high school years. I hope that my experience with NOAA Teacher at Sea will inspire at least one student to pursue science, and maybe even ocean science, as a career! There is so much out there to be explored in the ocean, atmosphere, landscape, and even space!
Alaska is about to be the 34th state I have visited in my life! I never really understood how far away it was until my flights for this trip were booked. After departing Atlanta, Georgia, I will land briefly in Portland, Oregon and then Anchorage, Alaska before arriving in Nome, Alaska. From there, I will board NOAA Ship Fairweather for Point Hope. The flights and layovers alone will take 16 hours! It is quite amazing how far the United States stretches!
My trip from Atlanta, Georgia to Nome, Alaska will span 3 flights and 16 hours.
NOAA Ship Fairweather will be my home for 12 days next month where I will help conduct a hydrographic survey of the Point Hope region in northwestern Alaska. We will be so far north that we may cross the Arctic Circle! Only 30% of this region’s ocean floor has ever been surveyed, and those surveys need updating because they took place in the 1960s. Updated and new surveys will be vital for the continued safe navigation of the ever-increasing maritime traffic, especially because the size of the vessels navigating the local waters continues to grow.

Science and Technology Log
Most of the blog posts I write onboard NOAA Ship Fairweather will tie back to physical science, so today I would like to discuss some earth science! Point Hope, AK is located at 68.3478° N latitude and 166.8081° W longitude. As you may know, Earth is divided into 90° of latitude per hemisphere, so 68° is pretty far north! In comparison, Harlem, GA is located at 33.4146° N latitude and 82.3126° W longitude.
What is significant about a region’s latitude? Latitude affects many things including sunlight distribution, seasons, and climate. For most of us in the United States, we know that summer days are long and winter days are short (in reference to hours of sunlight per 24 hour day). In Alaska the effect is much more dramatic! Parts of Alaska experience 24 hours of daylight around the summer solstice in June and 24 hours of darkness around the winter solstice in December. Not only are the daylight hours much different than what most of us experience, the concentration of sunlight that reaches Alaska is different too.
No matter which hemisphere you live in, as your latitude increases away from the equator (0° latitude) the amount of sunlight that reaches you decreases. The sun has to travel a longer distance through more of Earth’s atmosphere to reach you. As the light travels, it becomes more diffuse and less of it reaches its final destination: the Earth’s surface. The less direct sunlight makes those places feel cooler throughout the year than places like Ecuador, which is close to the equator and gets direct sunlight year round. Regions closer to the equator also do not get the long summer days and long winter nights because their daylight hours average around 12 hours per day year round.
It’s a common misconception to think that Earth is closer to the Sun in the summer and farther in the winter. If this were true, summer would start in June all over the world! Instead, the Earth’s tilt (at 23.5°) determines which hemisphere is pointing towards the Sun and that hemisphere experiences summer while the other experiences winter. As latitude increases, the seasonal effect becomes more dramatic. In other words, the difference between summer and winter is more and more noticeable. That is why warm, tropical places near the equator stay warm and tropical year round.
With all of this important science to consider, my 12 days in Alaska will definitely be an adjustment! I purchased an eye mask to help me to get restful sleep while the sun shines around me close to 24 hours per day. In addition, I will be packing plenty of layers to stay warm during the cool days and cold nights. In Georgia, most summer days reach temperatures in the mid-90s with high humidity. In contrast, Alaskan days on the water will reach 50s-60s on average.
Did You Know?
NOAA Ship Fairweather was built in Jacksonville, Florida in the mid-1960s, and its home port today is on the opposite side of the country in Ketchikan, Alaska.
Question of the Day
How many hours of daylight did you experience in your home state during the summer solstice on June 21? Nome, Alaska had 21 hours and 21 minutes of daylight!
