Science and Technology Log
In many ways, ships are like their own living organisms. From pontoons to sailboats, rowboats to mega-yachts, ships come in varieties just like plants and animals.
Preparing for the trip, I tried to approach learning about NOAA Ship Henry B. Bigelow as a species to study just like any other fish or bird species. I find research very comforting, so I tried my best to learn about ships in general, and the features of Henry B. Bigelow. NOAA has some excellent resources that cover the history, construction, and scientific specifications of the vessel. The end of this blog post contains links so you can dive even deeper, but here are some of the highlights (including some of my observations from onboard).
Basic Anatomy: Important Parts of a Ship to Know
Also called a command deck, wheelhouse, or pilothouse, the bridge is like the brain of the ship. This is where much of the navigation and mission logistics happen. Those working on the bridge also must maintain constant communication with other teams aboard, such as the engineers, scientists, and other crew.

On Henry B. Bigelow the bridge is very spacious and well-equipped with technology used to ensure that factors like the direction and speed are maintained as the scientific operations are performed. The bridge is commanded by a team of officers from the NOAA Commissioned Officer Corps.
The engine room is the heart and lungs of the operation. Without the engine machinery to propel the ship, you’re not getting very far. I have yet to see Henry B. Bigelow‘s engine room; that is a sensitive area. I’m a little nervous to inquire further because I know one thing for sure: engine rooms are LOUD.


What else could the mess and galley be other than the digestive system of a ship, of course? Food is stored and prepared in the galley and the crew aboard the vessel have their meals in the mess hall.
Also sometimes called cabins or berthings, staterooms for sleeping accommodations allow the hardworking crew aboard the ship to get some much-needed rest between watches. My room is a four-person room with two sets of bunk beds with a bathroom attached. There are also some rooms that are singles or doubles depending on the staffing needs of those onboard.
Life History
NOAA Ship Henry B. Bigelow is one of many within NOAA’s fleet of state-of-the-art research vessels. The construction of Henry B. Bigelow and other ships of the fleet were built with the intention of providing optimal facilities for NOAA’s scientists.

It was built in 2007 by VT Halter Marine Inc., in Moss Point, Mississippi. Because it was built for the purpose of being a fisheries survey ship, it has lots of unique characteristics not found in other vessels.
It has instruments used for recording crucial data for NOAA’s various projects. The ship is home ported in Newport, Rhode Island and its primary purpose is to perform fisheries stock research along the U.S. East Coast, including the Fall Bottom Trawl Survey that I am part of this year. Read even more about the other types of capabilities of Henry B. Bigelow here.
It recently underwent mid-life maintenance and its sister ship, NOAA Ship Pisces conducted the Spring Bottom Trawl earlier this year.
Personal Log
All aboard! We’ve arrived, folks. I landed in Rhode Island and was able to explore Newport. Okay, okay, perhaps I overpacked, but listen – my father, a retired U.S. Coast Guard Captain, instilled the official “Semper paratus” motto meaning “always ready” deep within me. Who knows what I might need?? Trekking about 100 lbs of luggage through the airport was quite the journey. I chose to count that walk to my rental car as my workout for the day.
After a lovely stay in Newport, I met up with the science team members that were also boarding the ship for the first leg of the bottom trawl survey. The large van transported us to the Navy pier where we then boarded a small boat to be transferred onto Henry B. Bigelow. Because we had about a dozen scientists with all their gear, we took multiple trips. I was on the last batch of folks transferred over so I boarded in the late afternoon. The evening included a whirlwind of orientation of the ship, safety trainings, and sneaking in a quick meal.

Now, time to get some much needed rest before the mission officially begins; can’t wait to start my first watch tonight!!!
Did You Know?
Something interesting I learned in my research was about some of the traditional terminology surrounding shipbuilding. Did you know that ships have specific stages of their construction? Laying the keel is the formal start of the ships construction.
