Science and Technology Log
Before getting into the technology that allows the scientific work to be completed, it’s important to mention the science and technology that make daily life on the ship safer, easier, and more convenient. Electricity powers everything from the powerful deck lights used for working at night to the vital navigation equipment on the bridge (main control and navigation center). Whether it makes things safer or more efficient, the work we’re doing would not be possible without power. Just in case, several digital devices have an analog (non-electronic) counterpart as a back-up, particularly those used for navigation, such as the magnetic compass.
To keep things cool, large freezers are used for storing bait, preserving scientific samples, and even storing ice cream (no chumsicles for dessert—they’re not all stored in the same freezer!). After one particularly sweltering shift, I was able to cool off with some frozen coffee milk (I improvised with cold coffee, ice cream, and milk). More importantly, without the freezers, the scientific samples we’re collecting wouldn’t last long enough to be studied further back at the lab on land.
Electricity also makes life at sea more convenient, comfortable, and even entertaining. We have access to many of the same devices, conveniences, and appliances we have at home: laundry machines, warm showers, air conditioning, home cooked meals, a coffee maker, TVs, computers with Wi-Fi, and special phones that allow calls to and from sea. A large collection of current movies is available in the lounge. During my downtime, I’ve been writing, exploring, enjoying the water, and learning more about the various NOAA careers on board.
To use my computer, I first needed to meet with Roy Toliver, Chief Electronics Technician, and connect to the ship’s Wi-Fi. While meeting with him, I asked about some of the devices I’d seen up on the flying bridge, the top deck of the ship. The modern conveniences on board are connected to several antennae, and Roy explained that I was looking at important navigation and communication equipment such as the ship’s GPS (Global Positioning System), radar, satellite, and weather instrumentation.
The weather devices on top are called anemometers, and they measure true wind speed and direction relative to the ship’s speed and direction. The term comes from the Greek word ‘anemos,’ which means wind. On the right is the fishing day shape, indicating to nearby ships that the Oregon II is using fishing gear.
These satellites help to provide the television and internet on the ship.
I was also intrigued by the net-like item (called a Day Shape) that communicates to other ships that we are deploying fishing equipment. This lets nearby ships know that the Oregon II has restricted maneuverability when the gear is in the water. At night, lights are used to communicate to other ships. Communication is crucial for safety at sea.
When I stopped by, Roy had just finished replacing some oxygen sensors for the CTD (that stands for Conductivity, Temperature, and Depth). For more information about CTDs click here: https://oceanexplorer.noaa.gov/facts/ctd.html
A dissolved oxygen sensor to be mounted on the environmental profiler, which collects environmental data through the water column.
A CTD refers to several electronic instruments that measure conductivity, temperature, depth, and other properties in the water column. Scientists are interested in changes in these properties relative to depth.
Without accurate sensors, it’s very difficult for the scientists to get the data they need. If the sensors are not working or calibrated correctly, the information collected could be inaccurate or not register at all. The combination of salt water and electronics poses many interesting problems and solutions. I noticed that several electronic devices, such as computers and cameras, are built for outdoor use or housed in durable plastic cases.
On this particular day, the ship sailed closer to an algal bloom (a large collection of tiny organisms in the water) responsible for red tide. Red tide can produce harmful toxins, and the most visible effect was the presence of dead fish drifting by. As I moved throughout the ship, the red tide was a red hot topic of conversation among both the scientists and the deck department. Everyone seemed to be discussing it. One scientist explained that dissolved oxygen levels in the Gulf of Mexico can vary based on temperature and depth, with average readings being higher than about 5 milligrams per milliliter. The algal bloom seemed to impact the readings by depleting the oxygen level, and I was able to see how that algal bloom registered and affected the dissolved oxygen readings on the electronics Roy was working on. It was fascinating to witness a real life example of cause and effect. For more information about red tide in Florida, click here: https://oceanservice.noaa.gov/news/redtide-florida/
Chief Electronics Technician Roy Toliver in his office on the Oregon II. The office is like the ship’s computer lab. When he’s not working on the ship’s electronics, Roy enjoys reading out on the stern. It’s a great place for fresh air, beautiful views, and a good book!
Preparing and packing for my time on the Oregon II reminded me of The Oregon Trail video game. How to pack for a lengthy journey to the unfamiliar and unknown?
I had a hard time finding bib overalls and deck boots at the general store.
I didn’t want to run out of toiletries or over pack, so before leaving home, I tracked how many uses I could get out of a travel-sized tube of toothpaste, shampoo bottle, and bar of soap, and that helped me to ration out how much to bring for fifteen days (with a few extras, just in case). The scientists and crew of the Oregon II also have to plan, prepare, and pack all of their food, clothing, supplies, tools, and equipment carefully. Unlike The Oregon Trail game, I didn’t need oxen for my journey, but I needed some special gear: deck boots, foul weather gear (rain jacket with a hood and bib overalls), polarized sunglasses (to protect my eyes by reducing the sun’s glare on the water), lots of potent sunscreen, and other items to make my time at sea safe and comfortable.
I was able to anticipate what I might need to make this a more efficient, comfortable experience, and my maritime instincts were accurate. Mesh packing cubes and small plastic baskets help to organize my drawers and shower items, making it easier to find things quickly in an unfamiliar setting.
This is where we sleep in the stateroom. The blue curtains can be closed to darken the room when sleeping during the day. On the left is a sink.
Reading and dreaming about sharks!
Dirt, guts, slime, and grime are part of the job. A bar of scrubby lemon soap takes off any leftover sunscreen, grime, or oceanic odors that leaked through my gloves. Little things like that make ship life pleasant. Not worrying about how I look is freeing, and I enjoy moving about the ship, being physically active. It reminds me of the summers I spent as a camp counselor working in the woods. The grubbier and more worn out I was, the more fun we were having.
The NOAA Corps is a uniformed service, so the officers wear their uniforms while on duty. For everyone else, old clothes are the uniform around here because the work is often messy, dirty, and sweaty. With tiny holes, frayed seams, mystery stains, cutoff sleeves, and nautical imagery, I am intrigued by the faded t-shirts from long-ago surveys and previous sailing adventures. Some of the shirts date back several years. The well-worn, faded fabric reveals the owner’s experience at sea and history with the ship. The shirts almost seem to have sea stories to tell of their own.
As we sail, the view is always changing and always interesting!
Being at sea is a very natural feeling for me, and I haven’t experienced any seasickness. One thing I didn’t fully expect: being cold at night. The inside of the ship is air-conditioned, which provides refreshing relief from the scorching sun outside. I expected cooler temperatures at night, so I brought some lightweight sweatshirts and an extra wool blanket from home. On my first night, I didn’t realize that I could control the temperature in my stateroom, so I shivered all night long.
It’s heavy, tough, and grey, but it’s not a shark!
My preparing and packing didn’t end once I embarked (got on) on the ship. Every day, I have to think ahead, plan, and make sure I have everything I need before I start my day. This may seem like the least interesting aspect of my day, but it was the biggest adjustment at first.
To put yourself in my shoes (well, my deck boots), imagine this:
Get a backpack. Transport yourself to completely new and unfamiliar surroundings. Try to adapt to strange new routines and procedures. Prepare to spend the next 12+ hours working, learning, exploring, and conducting daily routines, such as eating meals. Fill your backpack with anything you might possibly need or want for those twelve hours. Plan for the outdoor heat and the indoor chill, as well as rain. If you forgot something, you can’t just go back to your room or run to the store to get it because
- Your roommate is sleeping while you’re working (and vice versa), so you need to be quiet and respectful of their sleep schedule. That means you need to gather anything you may need for the day (or night, if you’re assigned to the night watch), and bring it with you. No going back into the room while your roommate is getting some much-needed rest.
- Land is not in sight, so everything you need must be on the ship. Going to the store is not an option.
Just some of the items in my backpack: sunscreen, sunglasses, a hat, sweatshirt, a water bottle, my camera, my phone, my computer, chargers for my electronics, an extra shirt, extra socks, snacks, etc.
I am assigned to the day watch, so my work shift is from noon-midnight. During those hours, I am a member of the science team. While on the day watch, the five of us rotate roles and responsibilities, and we work closely with the deck crew to complete our tasks. The deck department is responsible for rigging and handling the heavier equipment needed for fishing and sampling the water: the monofilament (thick, strong fishing line made from plastic), cranes and winches for lifting the CTD, and the cradle used for safely bringing up larger, heavier sharks. In addition to keeping the ship running smoothly and safely, they also deploy and retrieve the longline gear.
Pulleys, winches, and cranes are found throughout the boat.
Another adjustment has been learning the routines, procedures, and equipment. For the first week, it’s been a daily game of What-Am-I-Looking-At? as I try to decipher and comprehend the various monitors displayed throughout the ship. I follow this with a regular round of Now-What-Did-I-Forget? as I attempt to finesse my daily hygiene routine. The showers and bathroom (on a ship, it’s called the head) are down the hall from my shared stateroom, and so far, I’ve managed to forget my socks (day one), towel (day two), and an entire change of clothes (day four). With the unfamiliar setting and routine, it’s easy to forget something, and I’m often showering very late at night after a long day of work.
I’m more than ready to cool off and clean up after my shift.
One thing I never forget? Water. I am surrounded by glittering, glistening water or pitch-black water; water that churns and swells and soothingly rocks the ship. Swirling water that sometimes looks like ink or teal or indigo or navy, depending on the conditions and time of day.
Another thing I’ll never forget? This experience.
In case I forget, the heat of the sun reminds me to drink water all day long.
Did You Know?
The Gulf of Mexico is home to five species, or types, or sea turtles: Leatherback, Loggerhead, Green, Hawksbill, and Kemp’s Ridley.
Many of my students have never seen or experienced the ocean. To make the ocean more relevant and relatable to their environment, I recommend the picture book Skyfishing written by Gideon Sterer and illustrated by Poly Bernatene. A young girl’s grandfather moves to the city and notices there’s nowhere to fish. She and her grandfather imagine fishing from their high-rise apartment fire escape. The “fish” they catch are inspired by the vibrant ecosystem around them: the citizens and bustling activity in an urban environment. The catch of the day: “Flying Litterfish,” “Laundry Eels,” a “Constructionfish,” and many others, all inspired by the sights and sounds of the busy city around them.
The book could be used to make abstract, geographically far away concepts, such as coral ecosystems, more relatable for students in urban, suburban, and rural settings, or as a way for students in rural settings to learn more about urban communities. The young girl’s observations and imagination could spark a discussion about how prominent traits influence species’ common names, identification, and scientific naming conventions.
