Science and Technology Log

Although our mission has been delayed by few days, there is still plenty of work to be done on board the NOAA Ship Henry B. Bigelow. The deck crew and engineering department have been working hard to prepare for our departure tomorrow morning.

Today, I had the opportunity to tag along with Kate and Patrick, two of our engineers, to learn more about the pre-check work they were completing. “On board ship, it is very important to keep the updated record of the quantity of liquids (in all forms) present in various tanks.” (Marine in Sight)

As part of the pre-check, Kate and Patrick recorded the readings from sensors, then manually checked the level of each fuel, bilge, and ballast water tank in a process known as “sounding” the tanks. They applied Kolor Kut paste to sound tape in the measurement range reported by the sensors and lowered the tape to the bottom of the tank. Upon retrieval, the paste changes color—from light pink to red for fuel and from brown to red for water—indicating the levels.

Kate and Patrick compared these manual measurements with the sensor readings to ensure the sensors were accurately reporting the levels. Then they used a table to convert the measurements to the number of barrels. Soundings are crucial for identifying leakages or losses of fuel, maintaining the ship’s stability, and ensuring that sufficient fuel and water are aboard for the voyage.

Personal Log

Meet My Roommates! There are so many amazing people aboard NOAA Ship Henry B. Bigelow for this mission. I would like to introduce you to my roommates who were kind enough to let me interview them for my blog and share information about their science career paths.

Emma stands one what is probably a boat in a marsh and holds up a snake for a photo. She wears orange fish gloves and a green high visibility vest. — Karen Beatty (Animals were handled in accordance with state and federal permits.)

What is your science degree, and how did you become interested in this field?

Emma Venarde recently graduated from Brown University with a double degree in Environmental Science, focused on Environmental Justice, and Music. Emma has always had a love for nature and became passionate about climate change as a child. She joined the Youth Climate Program and realized that she wanted to better understand human impact and discover ways to help humans and other animals and how they are affected by climate change.

Karen Beatty earned her bachelor’s degree in Zoology from Michigan State University, worked as an environmental consultant for five years, and recently graduated with a master’s in Ecology from Penn State University. Initially, Karen was interested in becoming a veterinarian, but she learned that she preferred working with exotic animals and focusing on their behavioral health. This led her to an interest in becoming a zookeeper but eventually transitioned to wildlife biology. For her master’s, Karen aimed to deepen her quantitative knowledge and understanding of anthropogenic disturbances.

What motivated you to become a NOAA at-sea volunteer?

Last summer, Emma participated in the NOAA Chesapeake Bay Office (NCBO) and decided to apply for another internship opportunity through NOAA student opportunities. She sought more experience in fieldwork, particularly in collecting data and understanding how it’s used for ocean energy. This unique experience aboard the NOAA Ship Henry B. Bigelow is something she wouldn’t typically get, and she’s thrilled to be part of it.

Karen joined this mission as a fellow of the Knauss Fellowship. She believes this fellowship will not only enhance her fieldwork experience, especially in data collection and analysis but will also help her achieve a federal career aligned with conservation and policy development.

What advice would you give my students who are interested in a science career?

Emma: We need more people who are not just good at understanding science but are also able to communicate, collaborate, and think critically.

Karen: Be well-rounded! Interdisciplinary learning is crucial. Having a solid understanding of and skills in math, communication, policy, and regulations is essential to being a successful scientist.

This is our stateroom, also known as a cabin, that we will be sharing for the next two weeks. It’s a cozy space designed for practicality, consisting of four bunks, a small office area, lockers for our personal belongings, and a bathroom with a shower. While the quarters are tight, it’s amazing how efficiently everything is arranged to make life at sea as comfortable as possible. We’ve settled in nicely, and this space will be our little home away from home as we embark on this exciting mission aboard the NOAA Ship Henry B. Bigelow.

Welcome

Hello from the Florida Keys! I am so excited to be embarking on my Teacher at Sea excursion in just 4 days. I will be joining the crew aboard NOAA Ship Gordon Gunter to participate in a Summer Ecosystem Monitoring Survey in the Northeast Atlantic, departing from Rhode Island and returning to port in Virginia. I am looking forward to working side by side with NOAA scientists, sharing knowledge with my students, and having the experience of a lifetime!

My students at Ocean Studies Charter School are prepared to follow me along on my journey via this blog and our online classroom. They have even practiced their own Summer Ecosystem Monitoring Survey of the Hardwood Hammock forest surrounding our school!

I hope you’ll join us in this adventure and check back here for more blog posts in a few days!

Science and Technology Log

I am very much looking forward to participating in the Summer Ecosystem Monitoring Survey aboard NOAA Ship Gordon Gunter. At Ocean Studies Charter School, we do projects to monitor the seagrass, mangrove, and coral reef ecosystems each year while out in the field. It will be interesting to see how NOAA scientists conduct these surveys; what tools and equipment they use, what animals and plants they will find, and what aspects of water quality they will measure.

The ecosystem we will be monitoring on the mission is called the Northeast U.S. Continental Shelf Large Marine Ecosystem (NES LME). You can just call it the “Northeast Shelf.” This ecosystem spans the coast and out to sea from North Carolina up to Maine. Scientists want to know a lot about this part of the ocean because it is very important for something we love to do here in the Keys: FISHING. Fishing is fun, but it’s also the way that many people in our country get their food and make money to live. Fishing is a major industry along the east coast, so the Northeast Shelf Ecosystem is considered a very important natural resource that we need to protect.

How can scientists understand and protect this resource? It starts with Ecosystem Monitoring.

An ecosystem is a place where living things and non-living things work together like a big machine. Each part of the machine, both living and non-living, is important for the whole system to work. For example, in an ocean ecosystem, every type fish is needed for the food web to function. Clean water and plenty of sunlight is needed for the ocean plants and phytoplankton to be healthy. The ocean plants are needed for the invertebrates that the fish eat… and the cycle continues! In order for scientists to understand the fish that are important to us, they need to understand EVERY piece of the ecosystem since it is all connected. That’s why we will be measuring lots of different things on our mission!

Monitoring means “observing and checking something over a period of time”. NOAA scientists observe, measure, and check on this ecosystem 6-7 times per year. Monitoring an ecosystem lets people know WHAT is going on within the ecosystem. Scientists can use this information to research WHY things are happening the way they are. Then, they can use modeling to find out WHAT might happen in the future. This helps the government make decisions about our precious resources and make plans for the future to keep our oceans healthy and our fish populations strong.

On our mission, scientists will collect plankton, invertebrates, and fish with special nets to count and measure them. They will look and listen for marine mammals and sea birds. They will take measurements of the water such as temperature, salinity (amount of salt), nutrient levels, and ocean acidification. These measurements will help them understand the quality of water and changes of the climate in this area. What other aspects of the ecosystem do you think are important to measure?

I can’t wait to see how we will take all of these measurements and what we will see out there!

Personal Log

I am proud to call myself the Marine Science Teacher at Ocean Studies Charter School in Tavernier, Florida Keys. We are a small public charter elementary school, focused on the surrounding marine environment and place-based learning. I teach science to all grades (K-5) and lead our weekly field labs. I even drive the school bus! We use the term “field labs” instead of “field trips” to highlight that we are not simply visiting a place. We are using the outdoors as our learning laboratory, working on projects, collecting data, and partnering with local organizations on our excursions. We study the local habitats of the shallow seagrass beds, mangrove forests, and coral reefs that we are so lucky to have in our backyard.

Upon my return from my Teacher at Sea mission, we will be hosting the grand opening of our new Marine Discovery Laboratory in the center of our school! After teaching marine science in an outdoor classroom for the past 7 years, I am excited for the opportunities that our state-of-the-art indoor lab will bring (no more visits from the local iguanas)!

Lionfish — Learning about lionfish in the lab.

My students impress and amaze me every day with their ideas and discoveries. I have watched them create and present model ecosystems, examine hurricane protection ideas by studying animal survival, and help scientists tag sharks to learn more about their populations. At the start of this new school year, I cannot wait to see what ideas they will come up with next!

It will be hard to be away from my family, especially my two awesome sons, ages 6 and 9. I hope they enjoy following along with Mom’s blog and that they are inspired by my experience!

I originally hail from New Hampshire but have lived in Florida for all my adult life. Prior to teaching, I worked on boats as an environmental educator and earned my captain’s license along the way. I have been a SCUBA instructor, marine aquarist, and guide for summer travel adventure camps. As a teacher, I have been lucky enough to also participate in “Teacher Under the Sea” through Florida International University. In this program, I assisted scientists under the ocean at the Aquarius Undersea Laboratory right here in the Florida Keys. Throughout my life, I have loved the ocean. One day, I hope to sail out to sea and travel the world on my own boat.
