Science and Technology Log

Today is our last day at sea and we have currently completed 53 stations!  At each station we send out the CTD.   CTD stands for Conductivity, Temperature and Depth.   However, this device measures much more than that.  During this mission we are looking at 4 parameters: temperature, conductivity, dissolved oxygen and fluorescence which can be used to measure the productivity of an area based on photosynthetic organisms.

Once the CTD is deployed, it is held at the surface for three minutes.  During this time, 4,320 scans are completed!  However, this data, which is used to acclimate the system, is discarded from the information that is collected for this station.

The crane lifts the CTD from the well deck and deploys it into the water.

Next, the CTD is slowly lowered through the water until it is about 1 meter from the bottom.  In about 30 meters of water this round trip takes about 5 minutes during which the CTD conducts 241 scans every 10 seconds for a grand total of approximately 7,230 scans collected at each station.

Our CTD scans have gathered the expected data but during the summer months the CTD has found areas of hypoxia off the coast of Louisiana and Texas.

Data from CTD scans was used to create this map of hypoxic zones off the coast of Louisiana in summer of 2018.

 

Personal Log

The gloomy weather has made the last few days of the voyage tricky. Wind and rough seas have made sleeping and working difficult. Plus, I have missed my morning visits with dolphins at the bow of the ship due to the poor weather.  But seeing the dark blue water and big waves has added to the adventure of the trip.

Dark clouds lifting

The gloom is lifting as a tanker passes in the distance.

We have had some interesting catches including one that weighed over 800 pounds and was mostly jellyfish.  Some of the catches are filled with heavy mud while others a very clean. Some have lots of shells or debris.  I am pleasantly surprised to see that even though I notice the occasional plastic bottle floating by, there has not been much human litter included in our catches.  I am constantly amazed by the diversity in each haul.  There are species that we see at just about every station and there are others that we have only seen once or twice during the whole trip.

I am thrilled to have had the experience of being a NOAA Teacher at Sea and I am excited to bring what I have learned back to the classroom to share with my students.  

 

Challenge Question:

Bonus points for the first student in each class to send me the correct answer!

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

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.

red snapper 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.

Personal Log

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

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

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

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

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

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.

Science/Technology and Personal Log

Hurricane Michael brought a three day delay to our departure. At first, I was a little disappointed that we were not setting sail right away but now I am glad because I had some extra time to explore Pascagoula, familiarize myself with the ship, and slowly meet the crew as they arrived spread out over several days. Plus, the additional time allowed me to start working on my career lesson plan and to prepare a video tour of the ship. I will upload the video to this blog page as soon as it is complete.

#1 – My first tour of Oregon II #2 – Hurricane Michael arrives in the center of where I am and my hometown of Tampa #3 – Exploring Round Point Lighthouse #4 – My first sunset aboard.

On Thursday, Oct 11th at 9:00am, we departed from Pascagoula and headed out into the Gulf of Mexico. I was amazed at how quickly we lost sight of land and at the vastness of this body of water with which I thought I was so familiar. My favorite part was watching the color of the water change from a dark teal to a deep blue.

On the “Plan of the Day” board under schedule it reads “Steam and Dream til Saturday Afternoon” and that is just what we are doing. Our path will lead us north of the Mexican border and south of Corpus Christi, Texas, where we will find our first station. Until then, in between steaming and dreaming, we are getting to know each other and learning about our roles and responsibilities.

 

 

 

 

 

 

Abandon ship drill

Abandon ship drill! Here I am in my survival suit.

For example, today we practiced our Fire and Abandon Ship Drills. While it is a little nerve-racking to think that something like that could actually happen, it was reassuring to see that everyone was well-trained and the operations ran smoothly.

 

 

 

 

 

 

 

 

My first lesson plan will focus on careers available through NOAA. It is amazing to see the variation in the positions and the backgrounds of the workers on this ship. Basically, on the Oregon II there are three types of employees who make up the ship’s complement.

Types of Employees

This graphic illustrates the structure of the employees aboard Oregon II.

I feel like NOAA has something to offer everyone from entry level positions that require no experience to positions requiring years of experience or advanced college degrees. The best part is that no matter where you start there is always room to advance through hard work and certification. I can’t wait to share all the opportunities with my students!

 

Did You Know?

Oregon II has a reverse osmosis system that uses salt water to create the freshwater needed aboard.  The salt that is removed is returned back to the Gulf.

Science and Technology Log

The past three days were light catch days.  One day, we only caught a snake fish, which, as you can see, is a pretty tiny little guy.  But, the data from a catch that brings up nothing is just as important as a catch that brings up 50 fish.  As the saying goes, “If we always caught something, we would call it catching, not fishing.”  We have brought up a few Sandbar sharks and Tiger sharks, some of them large enough to have to cradle.  I have gotten to tag a few of the Sandbar sharks, which is still an amazing experience.

Snakefish

Snakefish, our only catch one day

While we did not see many sharks, I had fun seeing the other organisms at the surface.  There have been a lot of moon jellyfish as we have been pulling the line in, and it was clear enough that I was able to get a picture of a few of them as they floated by.  One night, there were flying fish next to the ship, and one of them jumped onto the deck, so I was able to see one up close.  One of the days, a pod of dolphins joined us on a run, and followed the boat for quite a while.  So, while we did not see many sharks, I was able to see some awesome animals throughout the past few days.

The last night on the ship, I finished cleaning my shark jaws.  Overnight, they soaked in hydrogen peroxide to whiten them, and today I set them to dry.  I’m looking forward to taking them home and sharing them with all of my students.

It was an amazing two weeks.  On Friday night, we set our last line, and it was bittersweet.  Over the past two weeks, I have been able to fish with an amazing group of people.  They allowed me to be a part of the team, and attempt each job setting and pulling in the line.  I was able to put out the high flyer, sling bait, place numbers, clean barrels, and keep data on the computer.  I learned how to tie a double-overhand knot, handle small sharks, tag sharks of all sizes, and had lots of fun doing it.  I’m excited to head back to T-STEM Academy at East High School, but I will always fondly remember my time on the Oregon II.

Personal Log

One of the things that the night shift has done a few times is midnight hot dogs.  Chris, the night shift lead fisherman, brings different types of hot dogs on the boat and will cook them at midnight for the shift change.  It gives the night shift members something to eat before breakfast at 7 AM, and gives the day shift something to eat before bed.  They go all out, with a condiment bar and gourmet buns.

 

Did You Know?

Once the Oregon II returns to port from this fourth leg of the Shark/Red Snapper Longline Survey, they will spend a week cleaning and preparing the ship to return to the Gulf of Mexico on a Groundfish Survey that will run from October 8-November 21.  NOAA Groundfish surveys allow for the collection of data on the distribution of flora and fauna within the target region through the use of trawl nets.

 

Quote of the Day

The charm of fishing is that it is the pursuit of what is elusive but attainable, a perpetual series of occasions for hope.

Question of the Day

Sharks have teeth that are constantly being replaced.  How many teeth will the average shark go through in their lifetime?
