Weather Data from Newport, Oregon
NOAA Weather Service forecast for Wednesday, July 19th as of 7/17/23 6:35pm:
Mostly sunny, then sunny and breezy, with a high of 61 degrees. Wednesday night’s low around 55 degrees.

“Weather” is what it’s doing today. “Climate” is what it did today in 1942. Climate equates to the prevailing weather trends for a particular region. Having been born and raised in Oregon I know that you always dress in layers when going to the Oregon Coast. I know that sunburn is possible in March (anytime really) and balmy 60-degree weather is possible in February. Historically, the average temperature for the month of July in Lincoln County has remained between 60 and 63 degrees with a slight trend upward. I imagine it is a bit chillier out on the Pacific. I have packed accordingly!

A week from departure (July 16th) I was looking south from the cliffs on Cape Lookout near Tillamook, Oregon. The breeze was visible in shimmering white flashes across the surface of the ocean even as the tidal swells plowed steadily into shore beneath the gusts. The infamous summer fog shrouded much of the cape’s seaward view due to temperature and pressure differences between the coast and inland.

view of Cape Lookout from the cliffs. Beyond dirt cliffside and conifer trees, we can see the water is a vivid blue-teal color. A mountain range marks the far side of the cape. The sky is blue, but fog rises off the water.

As air heats up it ascends (rises), leading to low pressure at the earth’s surface. As air cools down it descends (sinks), leading to high pressure at the surface. Hot summer air rises inland and creates low pressure. Since the temperature of the ocean is much colder, high atmospheric pressure is formed. Higher-pressure air tends to move into lower-pressure regions, so the moist marine layer (caused by evaporation) gets pulled off the top layer of the water and moves inland. All that moisture creates low-flying clouds, known as “fog” when it touches the ground. Marine fog moves eastward (inland) and usually clings to the shoreline. Sometimes it moves further depending on the topography of the coast range. Summer winds on the Oregon Coast are caused by temperature-driven atmospheric pressure disturbances where the two pressure systems collide.

Listening to the weather forecast was something of a ritual in my childhood home. Mom would tune in to WKL96 at 162.475 and we’d dutifully hush up when the familiar “ding!” occurred to signal the top of the broadcast. To this day she still writes down the short-term forecast and puts it on the fridge. (Mom is an old-fashioned gal and doesn’t use the internet.) Find your local station here.

I got to tour my local National Weather Service office –home of the “ding!”– in Portland, Oregon during a DataStreme Climate class I took in 2016. Sponsored by the American Meteorological Society, I also took their DataStreme Oceans course. I highly recommend these classes to educators.

I’m a bit of a NOAA snob when it comes to the forecast. My old Subaru had a channel entirely devoted to NOAA Weather Radio. My new (used) one doesn’t, and I miss it! Friends and family look at a variety of weather apps, but I will always check their predictions against what NOAA says. When you visit National Park Visitor Centers around the country it’s usually the short-term NOAA forecast that is posted on visitor information boards. It is possible to access NOAA Weather from your phone. Go to the following website to learn how to add a bookmark to your phone’s home screen.

the cover of the book A Crack in the Sea by H. M. Bouwman.

Librarian at Sea

“Traditionally, a few people from Raftworld would decide to stay on the island; and a few from the Islands would elect to join Raftworld. These were volunteers, and they were celebrated for their choosing, for some people were simply happier living on land, and others happier at sea.” 
~H. M. Bouwman, A Crack in the Sea
(G.P. Putnam, 2017)

A Crack in the Sea is a middle-grade novel that blends fantasy with historical fiction, including characters who flee a slave ship, and those fleeing post-war Vietnam. One character also has a special skill: talking to fish. My special skill is talking to children about books…but I do much more than that. 

Introduction & Background

I have reported to 551.46 many times over my 18 years as a school librarian, but this will be my first reporting to its physical manifestation. Despite growing up near the coast I have never been out on the open ocean in a boat. I have visited the nonfiction shelves (organized by Melvil Dewey) countless times. You’ll find oceanography topics at 551.46. You’ll find my school, Peninsula Elementary, on an earthen finger of Portland, Oregon bordered by the Willamette River to the west and the mighty Columbia River to the north. Peninsula has been my anchor as an educator for the past 12 years. I call myself a “teacher librarian” in order to emphasize that my priority is to design and deliver lessons to students on top of managing a small library. My profession has state and national standards that cover information literacy, reading engagement, and social responsibility. One of the things I love most about being a school librarian is the academic freedom that I have. I can teach my standards by using the story of the haenyo mermaids of Korea, by analyzing infographics of the water cycle, and by playing truth or lie with shark facts. Cross-curricular approaches to learning are what get me excited about teaching. Science in particular is a subject I have long gravitated towards. 

My career in a, er, clamshell: As an undergraduate with a BA in Comparative Literature I said, what next? I promptly got a seasonal job as a Ranger Aide for Silver Falls State Park. What next? I applied to permanent ranger jobs…and my old school district (where I graduated high school) was looking for a school librarian. My alma mater hired me with zero experience on a restricted transitional license–which means I promised to go back to school and get certified. So, I got my teaching license, then a Master’s in Library Science–two distinct programs. While in graduate school I began branding myself as a “Ranger Librarian.” While working for the same junior high I once attended, I had the odd experience of working with colleagues who were formerly my teachers. A beloved high school social studies teacher still worked next door on our shared campus. He encouraged me to seek out opportunities for educators that provided residencies, travel opportunities, and hands-on learning. So, when I saw a brochure in the staff lounge for an Outward Bound course designed just for teachers I applied. What next? I applied for a Cultural Resources Internship at Grand Teton National Park where, among other things, I created an information package for prospective researchers to help them navigate the application process and eliminate research redundancy. I learned, for example, there is such a thing as collecting too many voles. I applied for a “Teacher Ranger Teacher” position at Grand Canyon National Park. I applied to be a seasonal ranger again, this time in the Columbia River Gorge. I applied for a Comparative Mountain Geography Institute with the Center for Geography Education in Oregon. I did all those things in the margins of my life as a teacher librarian. What next? I applied to be a NOAA Teacher at Sea! 

As the others in NOAA TAS Class of 2022 and 2023 will confirm, I then played the pandemic waiting game while the world figured out how to function with COVID. TAS candidates have to pass a medical clearance within a year of sailing so I even gave blood not once, but twice, while time and tide marched on. I have yet to sweat, and yet to cry, but the salt swims at the ready.

Science, Technology & Career Log
You can track the location of NOAA Ship Bell M. Shimada as well as other vessels here.  Alternatively, you can try this tracker.  Marine traffic includes all ships at sea such as tankers, military vessels, passenger ships, and fishing boats. An automatic identification system, or AIS technology, is used to follow traffic locations. The International Maritime Organization (a branch of the United Nations) launched the development of AIS as a collision avoidance tool for large vessels at sea that were not within range of tracking systems based on shore.

The IMO decided that all vessels over 300 gross tonnages on international voyages must have AIS aboard. A gross tonnage is calculated by measuring a ship’s volume. AIS allows ships to “see” each other and improves situational awareness before visual contact is possible. AIS is considered by some to be the most significant improvement to navigational safety since the development of radar. However, AIS is considered an enhancement and not a replacement for radar and other traffic services. Using a broadcast transponder system, AIS operates in the VHF (very high frequency) radio waves mobile maritime band. A complete system includes a transmitter and a receiver with data displayed on a screen (revealing the bearing and distance of nearby vessels). Originally, AIS made broadcasts from ships to land and had a capacity of 20 miles or so. Today, satellite-detected AIS allows us to “see” ships no matter how far away.

Radio waves are one type of electromagnetic radiation–in the same family as X-rays, visible light, microwaves, infrared, and ultraviolet. Naturally occurring radio waves include lightning and objects in space including Jupiter and The Sun. It is possible to turn information like text, sound, and images into electrical signals. These signals are combined with radio waves–energy that moves–to send information across long distances. High-frequency waves have a shorter wavelength and send more wavelengths per second than low-frequency waves. In general, higher frequencies do not travel as far, which is why satellites have proven so useful to AIS. (Further reading)

Career feature

I am excited to meet all the people behind the research and ship operations. Prior to sailing, I checked out the professional mariner hiring portal facilitated by NOAA’s Office of Marine and Aviation Operations.  Current fleet vacancies included able seaman, oiler, and first assistant engineer. Reading the job descriptions brought to mind two things. One is my maternal grandfather. He was a World War Two Navy Veteran who worked as a motor machinist and drove a Higgins Boat on D-Day during the invasion of Normandy. He did not die in the war, but lived to age 89 and passed away in 2012. Among the family archives are records of his completion of a diesel mechanics course. This association made me think about encouraging students to make personal connections to whatever we are learning about.  After reminiscing about Grandpa, my train of thought spitballed keywords like boat, engine, ship, sailor, mechanic, and Titanic–which served as a bridge to thought number two. The fleet vacancies prompted a daydream about the next time I am helping a student interested in library books on one of these tangential ocean topics. In addition to a forthcoming lesson on NOAA careers, I should remember to mention a related career during book shopping and plant a seed. “Hey Johnny, I see you are interested in ships. Did you know that being a sailor is an actual job that you could do one day?”

NOAA Fisheries has its own job opening portal. Openings at the time of my website visit included a statistician, IT Specialist (systems administrators are needed everywhere!), fish biologist, physical science technician, grants management specialist, budget analyst, enforcement technician, and acquisition management specialist. Fish biologist was an obvious choice but I had to click on enforcement technician to find out more. It appears to be an entry-level position related to NOAA’s Office of Law Enforcement (see video insert).  

Holy mackerel, this initial career investigation blew my mind with how many employment opportunities there are within NOAA. I think my students will be impressed with the broad scope of career choices as well. 

Floating Facts

NOAA Ship Bell M. Shimada (in service since 2010) serves the entire West Coast and furthers the NOAA Fisheries mission to be “responsible for the stewardship of the nation’s ocean resources and their habitat.” The imperative of NOAA Fisheries is to maintain healthy ecosystems, safe sources of seafood, productive and sustainable fisheries, as well as the recovery and conservation of protected resources. NOAA’s parent agency is the U. S. Department of Commerce and so relates to economic growth and opportunity. Bell M. Shimada is known as a “quiet” ship, using technology to decrease its noise signature and increase scientists’ abilities to study fish without disturbing them. 

Bell M. Shimada, the man, was known for his studies of Pacific tuna stocks important to the development of commercial fisheries post-World War Two.  His name was chosen by a group of California high school students in a contest to name a new ship in the NOAA fleet. Born to Japanese immigrants in Seattle, Washington, he was imprisoned at Minidoka War Relocation Center in 1942 during the mass internment of Americans with Japanese ancestry. He was 20 years old at the time. He was able to leave the camp by enlisting in the U. S. Army. Shimada began as an infantryman, then an interpreter, translator, and radio traffic monitor, then compiled data on the impact of bombings in Japan. He ended up in Tokyo during its occupation and remained after the war in a civilian position where he analyzed the activities of Japanese fisheries. He returned stateside to finish a college degree that had been interrupted by internment. He went on to earn a Master’s and moved to Honolulu to work for the Fish and Wildlife Service. He worked with an influential fisheries scientist pioneering a holistic approach to fish management, blending fish biology with oceanography and meteorology. While in Honolulu he also began work on a Ph.D. The tuna research he is most well known for occurred when he was transferred to the Inter-American Tropical Tuna Commission in La Jolla, California. 
His scientific pursuits were cut short in a plane crash en route to Mexico City on a return trip from a scientific cruise to Clarion Island off the west coast of Mexico. Shimada was just 36 years old. Think of this remarkable scientist next time you open a can of tuna…

Hook, Line, and Thinker

As a part of my interdisciplinary approach to learning in the library, I often use philosophical questioning in order to inspire dialogue among my students. Something to think about…Is taking a creature’s life justified when it benefits the greater good? Many hake have given their bodies to science in order to not only benefit human activity but their own species as well.

Hmm, I made a Freudian slip just now. I originally wrote, “when it benefits the greater food.” I guess I’ve outed myself as a meat eater and a utilitarian when it comes to the sacrifice of creaturely bodies–within reason (remember the voles)–in the name of science.

During the three years I was sailing through the rough waters of the pandemic I took a hard look at the ocean-themed books in our school library collection. Library acquisition budgets are always tight, so I wrote a Donors Choose grant to purchase about 50 new titles. Since this occurred while I taught remote classes, my thank you package was also virtual. Students did a lovely job documenting their thanks using the tools they had available to them. I believe my NOAA experience will help me further promote the content of 551.46!

DO YOU KNOW YOUR ABCs?

Can you understand this sentence?

“During a watch change, the XO checked the AIS then handed control over to the  CO.  When contacted by the mapping room regarding the XBT launch and CTD termination check, the CO said,“Roger that”.  

After reading this- you’ll have a better idea what some of these acronyms mean and how we use them on the Okeanos Explorer. In other words, you’ll be able to say- “roger that” to show you understand and agree.

Let’s start with the XO and CO  –  They are easy and make sense.

CO – The Commanding Officer – He or she is responsible for everything on the ship. (see Personal Log for more information on Commander Ramos of the Okeanos Explorer)

XO – The Executive Officer – Reports to the Commanding Officer and is second in command.

AIS –What is it and why do we need it?

Okeanos Explorer AIS screen

Automatic Identification System.  The Okeanos Explorer has an electronic chart display that includes a symbol for every ship within radio range.  Each ship “symbol” tells Commander Ramos the name of the ship, the actual size of the ship, where that ship is going, how fast it’s going, when or if it will cross our path, and a lot of other information just by “clicking” on a ship symbol!  Here is a link to get more information on AIS.  I also took a picture of the Okeanos Explorer AIS screen and below that there’s the actual picture of our closest neighbor,  the ship named “Joanna”(look closely on the horizon) .  If the CO feels like the ship is going to need to change course, he will inform the scientists in the mapping room right away.  Safety and science RULE!

XBT- What is it and why do we need one?

Sam Grosenick, mapping intern, launches the XBT.

Every two or three hours the mapping team calls the bridge (the driver seat of the ship) and asks permission to launch an XBT – which is short for an eXpendable BathyThermograph.   That’s a heavy weighted probe that is dropped from a ship and allows us to measure the temperature as it falls through the water. WHY do we need to measure the temperature of the water if we are using sonar?  Sound waves travel at different speeds in different temperature water, just like they travel at different speeds in cold air than warm air.  So they need to know the temperature of the water to help calculate how fast the sound or ping that the ship’s sonar sends out so they can map the bottom of the ocean.  A very thin wire sends the temperature data to the ship where the mapping team records it.  There is more information about XBT’s here:

CTD – What is it and why do we need one?

Chief Electronics Technician Richard Conway and Chief Boatswain Tyler Sheff prepare for a dawn launch of the CTD

Many oceanographic missions use CTD’s.  The Okeanos Explorer is no exception.  CTD stands for conductivity, temperature, and depth, and refers to the electronic instruments that measure these properties. The grey cylinders are water sampling bottles and the big white frame protects everything.   WHY do scientists need CTD’s? Scientists use a CTD to measure the chemistry of the Ocean from surface to bottom.  The CTD can go down to near the bottom and the cylinders close when the scientist on board ship pushes a key on the computer and close so that a water sample is captured at that depth.  It’s a lot easier than swimming down there and opening up a jar and closing it.

WHY do they want to know about conductivity? Why do they care how much electricity can go through the water?   If the water can conduct more electricity, then it has a higher salinity, i.e. more salt.   That helps the scientists know the density of the water at that depth and can help inform them of the biology and ocean currents of that area.

Personal Log 

Commander Ramos at the helm
Commander Ramos at the helm

As I mentioned in last blog, everyone plays a part on the Okeanos Explorer.  The CO plays a big part in making sure the scientists achieve their goals.  The man in charge- Commander Ricardo Ramos answered a few of my questions last night  in his office in the forward part of the ship.

When I say Oregon Trail, fifth graders usually think of covered wagons.  I doubt that they think of a family of immigrants from Mexico deciding to leave family and friends in sunny Los Angeles and hit the trail north to rainy Oregon. But the devastating riots in Watts in the 1960s caused Commander Ricardo Ramos’s parents to do exactly that. There were some adjustments to be made to life in tiny Klamath Falls, Oregon but his parents, 3 brothers and sister were up to the challenge of no family support and a new community.  The family worked for Weyerhaeuser and Commander Ramos knew he did not want to work in the plant the rest of his life.  It was never IF he’d go to college, but “WHERE”.  He was the second of the five children to attend college, earning 2 Associates degrees and a degree in Electrical Engineering.   After entering NOAA and gaining his masters from Averett University, he spent time on various NOAA ships and in other capacities.  He is also a graduate of Harvard’s Senior Executive Fellows program.

He had a couple words of advice for elementary school students.  First, take advantage of all learning opportunities, for you will never know when you might need the knowledge you will gain.  Second, that communication, both written and oral,  is probably the most important part of his job.  He is not afraid of getting input and editing of his writing for the job.  His greatest reward is realizing that he is charge of a tremendous asset of the United States that provides a platform for scientist to explore our vast oceans.

 

Did You Know? 

My ship – The Okeanos Explorer is about  70 meters - the length of the top of the  arch on the Eiffel Tower!
My ship – The Okeanos Explorer is about 70 meters – the length of the top of the arch on the Eiffel Tower!

Displacement – When you think displacement, you probably think of a quick definition like “moved aside” that we learned when we made aluminum foil boats.  When you get in a kiddie pool, bathtub or any body of water, you move aside water. If you measure the weight or amount of water that you move aside, that is your displacement.  The Okeanos Explorer moves aside a lot of water – more than 2,500 TONS of water.  That’s about 700,000- gallons of water that gets displaced.  The ship is 224 feet long and 43 feet wide in its widest part.  Now, I don’t know about you – but I start thinking about the really big ships and tankers that we see passing by the Okeanos Explorer on the radar (their ‘deets’ are given to us by the AIS system – See the Section on ABC’s for an explanation of AIS) Well, there was a ship called “The Knock Nevis” and it was 1500 feet long!  Did it displace water?  You bet!. 650,000 tons of water when fully loaded! (use a ton of water = gallon converter on google to figure out how many gallons that is). Let’s just say that it’s a lot more than our little MUFFIN – the winner of the Coon Creek Boat Race.
