Science and Technology Log
After our delayed departure, we are finally off and running! The science team on Oregon II has currently completed 28 out of the 56 stations that are scheduled for the first leg of this mission. Seventy-five stations were originally planned but due to inclement weather some stations had to be postponed until the 2nd leg. The stations are pre-arranged and randomly selected by a computer system to include a distributions of stations within each shrimp statistical zone and by depth from 5-20 and 21-60 fathoms.
Planned stations and routes
At each station there is an established routine that requires precise teamwork from the NOAA Corps officers, the professional mariners and the scientists. The first step when we arrive at a station, is to launch the CTD. The officers position the ship at the appropriate location. The mariners use the crane and the winch to move the CTD into the water and control the decent and return. The scientists set up the CTD and run the computer that collects and analyzes the data. Once the CTD is safely returned to the well deck, the team proceeds to the next step.

Step two is to launch the trawling net to take a sample of the biodiversity of the station. Again, this is a team effort with everyone working together to ensure success. The trawl net is launched on either the port or starboard side from the aft deck. The net is pulled behind the boat for exactly thirty minutes. When the net returns, the contents are emptied into the wooden pen or into baskets depending on the size of the haul.
This unusual haul weighed over 900 pounds and contained mostly red snapper. Though the population is improving, scientists do not typically catch so many red snapper in a single tow.
The baskets are weighed and brought into the wet lab. The scientists use smaller baskets to sort the catch by species. A sample of 20 individuals of each species is examined more closely and data about length, weight, and sex is collected.
The information gathered becomes part of a database and is used to monitor the health of the populations of fish in the Gulf. It is used to help make annual decisions for fishing regulations like catch and bag limits. In addition, the data collected from the groundfish survey can drive policy changes if significant issues are identified.
I have been keeping in touch with my students via the Remind App, Twitter, and this Blog. Each class has submitted a question for me to answer. I would like to use the personal log of this blog to do that.
3rd Period – Marine Science II: What have you learned so far on your expedition that you can bring back to the class and teach us?
The thing I am most excited to bring back to Marine 2 is the story of recovery for the Red Snapper in the Gulf of Mexico. I learned that due to improved fishing methods and growth in commercial fishing of this species, their decline was severe. The groundfish survey that I am working with is one way that data about the population of Red Snapper has been collected. This data has led to the creation of an action plan to help stop the decline and improve the future for this species.
4th Period – Marine Science I: What challenges have you had so far?
Our biggest challenge has been the weather! We left late due to Hurricane Michael and the weather over the past few days has meant that we had to miss a few stations. We are also expecting some bad weather in a couple of days that might mean we are not able to trawl.
5th Period – Marine Science I: How does the NOAA Teacher at Sea program support or help our environment?
The number one way that the NOAA Teacher at Sea program supports our environment is EDUCATION! What I learn here, I will share with my students and hopefully they will pass it on as well. If more people know about the dangers facing our ocean then I think more people will want to see changes to protect the ocean and all marine species.
7th Period – Marine Science I: What is the rarest or most interesting organism you have discovered throughout your exploration?
We have not seen anything that is rare for the Gulf of Mexico but I have seen two fish that I have never seen before, the singlespot frogfish and the Conger Eel. So for me these were really cool sightings.
8th Period – Marine Science I: What organism that you have observed is by far the most intriguing?
I have to admit that the most intriguing organism was not anything that came in via the trawl net. Instead it was the Atlantic Spotted Dolphin that greeted me one morning at the bow of the boat. There were a total of 7 and one was a baby about half the size of the others. As the boat moved through the water they jumped and played in the splashing water. I watched them for over a half hour and only stopped because it was time for my shift. I could watch them all day!
Do you know …
What the Oregon II looks like on the inside?
Here is a tour video that I created before we set sail.
Transcript: A Tour of NOAA Ship Oregon II.
(0:00) Hi, I’m Andria Keene from Plant High School in Tampa, Florida. And I’d like to take you for a tour aboard Oregon II, my NOAA Teacher at Sea home for the next two weeks.
Oregon II is a 170-foot research vessel that recently celebrated 50 years of service with NOAA. The gold lettering you see here commemorates this honor.
As we cross the gangway, our first stop is the well deck, where we can find equipment including the forecrane and winch used for the CTD and bongo nets. The starboard breezeway leads us along the exterior of the main deck, towards the aft deck.
Much of our scientific trawling operations will begin here. The nets will be unloaded and the organisms will be sorted on the fantail.
(1:00) From there, the baskets will be brought into the wet lab, for deeper investigation. They will be categorized and numerous sets of data will be collected, including size, sex, and stomach contents.
Next up is the dry lab. Additional data will be collected and analyzed here. Take notice of the CTD PC.
There is also a chemistry lab where further tests will be conducted, and it’s located right next to the wet lab.
Across from the ship’s office, you will find the mess hall and galley. The galley is where the stewards prepare meals for a hungry group of 19 crew and 12 scientists. But there are only 12 seats, so eating quickly is serious business.
(2:20) Moving further inside on the main deck, we pass lots of safety equipment and several staterooms. I’m currently thrilled to be staying here, in the Field Party Chief’s stateroom, a single room with a private shower and water closet.
Leaving my room, with can travel down the stairs to the lower level. This area has lots of storage and a large freezer for scientific samples.
There are community showers and additional staterooms, as well as laundry facilities, more bathrooms, and even a small exercise room.
(3:15) If we travel up both sets of stairs, we will arrive on the upper deck. On the starboard side, we can find the scientific data room.
And here, on the port side, is the radio and chart room. Heading to the stern of the upper deck will lead us to the conference room. I’m told that this is a great place for the staff to gather and watch movies.
Traveling back down the hall toward the bow of the ship, we will pass the senior officers’ staterooms, and arrive at the pilot house, also called the bridge.
(4:04) This is the command and control center for the entire ship. Look at all the amazing technology you will find here to help keep the ship safe and ensure the goals of each mission.
Just one last stop on our tour: the house top. From here, we have excellent views of the forecastle, the aft winch, and the crane control room. Also visible are lots of safety features, as well as an amazing array of technology.
Well, that’s it for now! Hope you enjoyed this tour of NOAA Ship Oregon II.
Challenge Question of the Day
Bonus Points for the first student in each class period to come up with the correct answer!
We have found a handful of these smooth bodied organisms which like to burrow into the sediment. What type of animal are they?
What type of animal are these?
