NOAA Ship Thomas Jefferson

NOAA Ship Thomas Jefferson is one BIG ship.  Here is a list of some of its characteristics:

  • Length overall: 208 ft
  • Beam: 45 ft
  • Draft: 14 ft below the keel (15.6 ft below the transducer pod)
  • Registered gross tonnage/Displacement: 1767 tons
  • Cruising speed: 11 kts
  • Survey Speed: 10 kts
  • Cruising range: 19,200 NM, 45 days
  • Authorized Officers and Crew: 34
  • Scientific Berths: 4 (They can take up to 4 visiting scientists.)

Follow this link for more information about NOAA Ship Thomas Jefferson.

One thing not on this list is that currently, TJ is carrying four other boats + 6 life rafts aboard.  Of the boats aboard, two are the survey launches (mentioned in a previous blog), one is a Fast Rescue Boat (FRB) that is very fast and maneuverable (more about the FRBs in a future post), and the last is a work boat affectionately called 1717.  It is an inflatable boat with a ridged hull.  It is frequently used to do preservation work on the hull and inspect areas for future work.

Today, the crew used the 1717 to do a crew transfer to Erie, PA.  A crane (not a davit) is used to move this boat on and off the ship.

  • Crewmembers wearing hard hats stand in position around the boat. a crane hook lowers into view.
  • crewmembers secure hook to boat with harness attaching at four points
  • crewmembers steady boat as crane lifts it off the deck
  • crewmembers stand back as crane lifts boat above everyone's heads
  • crane swinging boat over the fantail
  • view of the boat suspended over the water
  • view of the boat suspended over the water, lowering
  • boat suspended over the water by the crane
  • boat being lowered to the water's surface
  • view of boat on water's surface, still attached to crane hook
  • overhead view of the boat, now with three crewmwmbers aboard

Able Bodied Seaman (AB) Thompson runs the crane and Chief Boatswain (CB) Pooser supervises getting the 1717 work boat in and out of the water.

There are many different types of ships.  People have been using ships for a long time! 

According to Britannica Kids,

“People use different types of ships for many different purposes. Some of the main types are trade ships, warships, industrial ships, and pleasure vessels, or cruise ships.

“Trade ships carry different types of cargo. Container ships carry cargo packaged in large containers. General cargo ships carry lumber, farm products, and other goods that are hard to ship in containers. Bulk ships carry coal, grains, and other loose cargo. Tankers carry oil and other liquid cargo. Refrigerated ships, or reefers, carry meat, fish, and other products that need to stay cold.

“Navies use several different kinds of warships. The largest are aircraft carriers. A carrier has a large flat surface called a flight deck that airplanes can use for takeoffs and landings. Other types of military ships include cruisers, destroyers, and submarines.

“Industrial ships are sometimes called factory ships. Some industrial ships are oil rigs. They have big machinery that pumps oil from the ocean floor. Another type of factory ship processes fish that the crew catches at sea.

“Before airplanes made long-distance travel quick and easy, people traveled in ships called ocean liners. Ocean liners had dining rooms and cabins where guests could sleep. Today this type of passenger ship is called a cruise ship. Cruise ships carry tourists and vacationers to seaside locations around the world. Cruise ships often have swimming pools, shopping malls, and live entertainment.”

History of Ships

From Britannica Kids:

“In early times people moved ships with oars. Many early ships also used the wind to move across the seas. These ships had sails—large, raised pieces of cloth that caught the wind. Ancient Egyptian warships had at least 40 oars and a single sail. The powerful longships of the Vikings also had oars and one sail.

“By the 1400s European ships had several sails. Sailing ships known as galleons carried large guns along their sides for making war. In the 1800s long, slim ships called clippers also had several sails. Clippers traveled faster than any ship before.

“Ships were made mainly of wood until the middle of the 1800s. At that time iron ships began to replace wooden ones. Steam-powered engines also began to replace sails.

Today most ships are made of steel or other modern materials. They have internal-combustion engines that run on diesel fuel or gas. Some modern ships run on nuclear power.”

Human-Interest Poll of the Crew

"What were the highest seas you have ever experienced? (Note to self: stay out of the Bering Sea!) 65ft in the Bering Sea, AK; 40+ ft in the Bering Sea, AK; 25 to 30 ft in the South China Sea; 20 to 30 ft approximately 2100 nm SE of Virginia; 20-25 ft in the Gulf of Alaska in January; 19 ft somewhere off the East Coast around North Carolina; 1+ ft off the coast of Presque Isle"

Personal Log – Christmas in July!

The U.S. Postal Service does not have an official moto.  If it did, it could be, “Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.”  What about Santa Claus?  He seems to deliver packages all over the world no matter the distance or weather!

Today, we had a delivery from a type of “Santa”.  At least that is what it felt like!  The U.S. Coast Guard delivered a package directly to our ship this afternoon.

Here comes Santa! He is bringing a very important package for our engineering department!

Our engineering department is very happy.  Maybe now they have what they need to fix one of our davits.  If the davits can be fixed, we will be able to deploy a launch (small survey boat) to assist with the survey mission.

It was fun to have some visitors, even if they just stayed for a few minutes.

Did you know . . .

Lake Erie is the fourth largest lake (by surface area) of the five Great Lakes?  It is the eleventh-largest lake in the whole world!

As I sign off, I will leave you with this thought: There are so many examples of career opportunities on Thomas Jefferson.  Do you like water?  Ships?  Machines?  Technology?  Cooking?  If you answered, “Yes” to any of these questions, a career with NOAA may be for you!  Think about it!

Science and Technology Log

Yesterday was probably the last RHIB ride I’ll ever get to go on and last night at midnight, we left the Stratus 5 buoy all alone moored to the Pacific Ocean floor. I felt a little wistful.

So far today has been a quiet day. We’re steaming toward the San Felix islands. We’ve started watch duty again. Alvaro Vera and I have watch duty together from 8:00 am to noon and from 8:00 pm to midnight. This evening we’ll do another CTD cast. All the WHOI guys are dismantling the old buoy and packing up all the components to be sent back to Woods Hole. I finally got tons of email from my students and many of them are tracking the adopted drifting buoy which makes me proud of them. It seems I’ve spent half the day answering them. I’ve enjoyed it though. It’s good to have connection across the miles. We came out from under the stratus cloud deck and what a beautiful day! People are sitting out on the fantail soaking in the sun and warmth.

Personal Log

I’ve just been out on the ship’s bow peering over the edge to watch the ship slice through the water. It’s mesmerizing and clears my mind of thoughts. I think it’s like meditating. It’s especially calming to just look and listen and forget everything else. I see the many hues of blue in the water. I hear the waves splashing and the hum of the ship’s engine. The salty air feels clean in my lungs. Even the greens of the slimy algae growth just below the water line add another dimension to the sights and sounds of life at sea.

With a clear mind and clean lungs,

Until tomorrow,

Mary

Question of the Day

For what purpose are the lights in the hallways colored red at night?

Positive Quote for the Day

“The life that conquers is the life that moves with a steady resolution and persistence toward a predetermined goal. Those who succeed are those who have thoroughly learned the immense importance of plan in life, and the tragic brevity of time.” W.J. Davison

Science and Technology Log

We had another early morning RHIB ride! The purpose was to visually inspect the newly deployed Stratus 5 buoy. It looked so small out there in the choppy ocean water. The buoy was found to be in good working condition with a minor break in a railing that surrounds the weather instruments that sit atop the buoy. The break will have no bearing on the workings of the instruments so all was approved by Jeff Lord, the WHOI engineering technician. Then we took another wild ride back to the mother ship!

I think today is a good day to show you pictures of the inside of the ship and talk about ship life. Here are some of my impressions of the ship interior. The hallways are narrow and if two people meet, one must step aside. The doors seem to weigh two tons and if one slammed on your fingers it would crush them off.

You must step up and over as you cross the threshold of a doorway. It’s built up to prevent water from getting into every room if there’s a flood. In the stateroom (bedroom), the bunk beds are comfortable but there’s no room to sit up in bed. The round windows are called portholes. The toilet (called the head) has no lid. The toilet is flushed by pressing a button then a powerful vacuum suctions everything down! There are handles to hold on to in the shower. The shower room doors have huge, strong magnets that hold them open. All the drawers and cabinets have latches so they won’t swing open when the ship moves around. Everything is tied down or secured in some fashion. There are no wheels on the office chairs. At night the hallway lights are turned to red instead of white. The food is outstanding. We eat three meals a day plus snacks are available 24 hours a day. There’s an exercise room and a laundry room and a TV room where two movies are shown each evening. There’s a library, too. It seems that computers are in every nook and cranny. There’s lots of equipment onboard like scientific instruments and big machinery. They make water on the ship. I’ll explain that on another day.

Diane, Bruce and I collaborated on the children’s book again today. Things are coming together nicely.

At “6:00 Science on the Fantail” we interview the Chief Scientist, Dr. Robert Weller of Woods Hole Oceanographic Institution. He gave us the reasons for placing the Stratus 5 buoy at this particular location in the Pacific Ocean. Bob said that there needs to be greater understanding of air-sea interactions for scientists to make better models and predictions of weather and climate patterns. The area just off the coast of Chile is one that has had minimal data collected in past years. Plus, it is an area that has a constant stratus cloud deck which isn’t clearly understood. That’s why the Woods Hole Oceanographic Institution and the Office of Climate Observation have partnered to fund the Stratus program for, possibly, as long as 15 years. Now, in its fifth year, the Stratus program has collected very useful data that has helped in better understanding the eastern Pacific Ocean and the weather that originates there. Dr. Weller was also very pleased with the work effort and cooperation between the WHOI scientists, the crew, and the Chilean scientists and students. It took a well organized work effort to get it all done. Now the WHOI scientists and engineers are taking the data collected from last year’s buoy and beginning the evaluation process.

I have to tell you about the exercise room. Last night, Diane invited me to go down for a workout. Diane’s a runner and so she goes to workout every evening. I’d never really taken a good look in there, except to see several pieces of equipment because I hadn’t brought any clothes or shoes appropriate for working out. So, I thought, why not? I need to exercise. So I put on my trusty, old clunky hiking boots and headed down to the exercise room. When I opened the door there was a red and black stairway leading down toward a yellow grate. Most of the exercise equipment was sitting on the grate. The room was dimly lit and the air was cool. I could hear the humming of fans. There was one gray door that had a claxon sounding off from within. I considered opening it but changed my mind. I saw a red “Danger High Voltage” sign and about ten huge carbon dioxide tanks sitting upright in the corner. There were some blinking lights coming from a partially opened doorway leading into another room. Running along the ceiling and walls were cables and pipes. I knew I was alone so I looked around to survey which machine I’d try first. Over in the far corner were rows of orange-colored coveralls hanging from the ceiling by their hoods with their arms outstretched. All the orange suits were moving with the swaying of the ship. It appeared as though people were inside the suits and just hanging in mid-air! I stopped, and looked around with an eerie thought. I felt like I was in an episode of Star Trek where they have rooms filled with extra worker-drones waiting to be activated during times of crisis. OK. Maybe I have been on this ship too long. But it’s a great place for the imagination to run wild. Don’t you think?

Until tomorrow,

Mary

Science and Technology Log

Today’s the big day! The Woods Hole Oceanographic Institution scientists will begin bringing the old Stratus 4 buoy onboard the RONALD H. BROWN. They’ve enlisted the help of just about everyone on the ship. At 6:00 this morning, the sky was dark blue and overcast. As daylight began to creep in, we all gathered in the main lab to prepare for the day’s work. First of all, the scientists triggered the acoustic release at the bottom of the ocean which is about 4400 meters deep. This released the buoy and array of instruments underneath it from the anchor. The 9000 pound anchor was left on the ocean floor. Then we waited.

And waited. And waited some more. It was about 45 minutes in all. We were waiting for the floats to come to the surface. The floats are big glass balls covered in yellow plastic hulls. They’re about the size of a medicine ball. And they are heavy, too. Wouldn’t you think a float would be lightweight? After the floats popped up out of the water, David, Phil, Jason and I went out on the RHIB to hook onto them and tow them to the ship. Once again the RHIB ride was awesome!

Pulling the floats onto the ship began the whole process of reeling in the old Stratus 4 mooring. This took all day. First they reeled in all the cable connecting the surface buoy to the anchor. At the beginning the buoy was a little speck near the horizon but as the cable got shorter, the buoy got closer and bigger until it was just behind the ship. That alone took several hours. When the instruments began coming in, we had to log and photograph each one. Then another RHIB ride was in order!

This was the RHIB ride of my life! Jeff, Diane, Jason, Phil and I went barreling across the swells and hit a wave that bounced Jason into midair for a second or two! I was hanging on with all my might and waves came over the edge right into my face. When we arrived at the buoy the guys hooked onto it and we towed it back to the ship. Then the crew on the ship hauled it aboard with a crane. While they were hauling it in we stayed out in the RHIB and pitched and rolled. That’s when I started to feel a little bit green. Fortunately, we were soon retrieved but on the starboard side of the ship…home, sweet home. We then watched the final removal of subsurface instrumentation. Wow! The Stratus 4 buoy was covered in amazing barnacles! Big ones and little ones. Long-necked barnacles are bizarre looking creatures. They attach themselves to anything in the water, just like suction cups. It’s like they’re stuck on with Super Glue. Once everything and everyone was safely onboard we had a barnacle scraping party. All available hands scraped those little rascals off and threw them back into the ocean. It was a mess but with everyone pitching in things got nicely cleaned. Tomorrow, we get everything ready for the deployment of the new and improved Stratus 5 buoy!

Positive Thought of the Day

“I think laughter may be a form of courage. As humans we sometimes stand tall and look into the sun and laugh, and I think we are never more brave than when we do that.” Linda Ellerbee

Science and Technology Log

This morning we arrived at the Stratus 4 buoy site! The buoy looked so small bobbing out there all alone on the ocean. David Owen took Jeff Lord, Phil Pokorski and I for a boat ride in the RHIB (rigid hull inflatable boat). The RHIB is an orange raft-looking motor boat. The RHIB is raised and lowered into the water on a lever lifting device called a small boat launch. We went out to make a quick inspection and to see if the temperature sensors were working. Jeff said it all looked pretty good and there weren’t as many barnacles as he’d expected. He took pictures then we returned to the ship. Today, all the scientists are quietly working on inter-comparison testing with the ship’s sensors and the buoy.

At “6:00 Science in the Main Lab”, we interviewed Jason Smith, an engineering technician for Woods Hole Oceanographic Institution. Jason explained the instrumentation that will be attached to the bottom of the Stratus 5 moored buoy. The first instrument is a temperature sensor, which is an electronic device. It has a resistance that changes with temperature and that resistance can be measured with an electronic circuit. These instruments can also measure conductivity which is an indicator of salinity. In addition, there are various styles of current meters used. Some are mechanical and some use acoustics. All these instruments will be suspended at different depths with most of them concentrated from the surface down to 300 meters. One problem that they encounter is marine animals adhering to the instruments and fouling up their functions. Different types and colors of anti-fouling paints are being tested to see which one inhibits the marine life from sticking to the machinery. Jason emphasized that it was very important to develop an anti-fouling paint that is both environmentally safe and keeps the marine life from setting up housekeeping on the instruments.

This evening, Diane and I sat down to begin writing the children’s book about the cruise. Don’t let anyone ever tell you this is easy. But we’re progressing nicely and I can see an interesting book emerging.

Personal Log

Well, the last thing my mentor, Diane, said to me last night was “Tomorrow will be a more relaxing day”. So I thought, “I’ll sleep in and take my sweet time getting out and about in the morning.” You know, do some of those personal hygiene things we often take for granted like blowing our hair dry and trimming our toenails.

And so there I am peacefully sleeping like a baby being rocked when Diane comes in and says, “Mary, Bob said the RHIB is leaving in about 30 minutes!” At first, I thought I was dreaming, but then I realized, “This is for real!” Anyway, I jumped up and threw on some clothes and ran out to the small boat launch deck. Sure enough, they were getting ready to leave. I made it in just the nick of time! Yeah! Diane and Bob had my life vest, hard hat and radio ready. I grabbed them and climbed in.

The RHIB ride was awesome! It’s funny how the ocean swells look a whole lot bigger when you’re in a little boat than from the ship’s deck. As the boat zipped up and down across the surface, I was hanging on for dear life and ocean spray was splashing me in the face and running down my back to make a puddle right where I was seated. The buoy would disappear then reappear time and again.

Even in all this excitement and adrenaline rush, my mind was thinking about those early explorers like the Polynesians who launched out in small thatched boats. For a moment, I felt a cosmic connection across time and cultures. And then it hit me, “What were they thinking? This is nuts!” I mean they had to be daring and bold of personage to cast their lives onto the rolling, endless waters in search of the unknown. Then, I gazed back on the RONALD H. BROWN, my temporary home, floating like a little toy ship in a great big tub. I like that ship. It’s like my whole universe for the next 2.5 weeks. Then what happens? My universe will disappear and everyone will go to their own real world lives. I’m still trying to wrap my mind around that thought.

After we did a visual inspection of the buoy, we posed for pictures and zoomed back to the mother ship. As David pulled alongside the ship, Phil and Jeff grabbed the ropes and hooked us up to the small boat launch, then, the operator lifted the RHIB aboard. We banged against the boat launch so hard it knocked my hat off! It went tumbling around in the bottom of the RHIB. I felt like one of those persons who loses their hat in the wind and keeps chasing after it.

We were all wet but with great big smiles on our faces. Riding the RHIB was as good as the Zippin’ Pippin’ rollercoaster in Libertyland! I’m ready to go again!

Until tomorrow,

Mary
