Science and Technology Log

While I have been at sea,  I have spent time exploring Pisces and getting to know the people on board. This research vessel is 209 feet long, 50 feet wide, and it has a draft of 20 feet.  It is large enough to hold 39 passengers. The crew of the vessel during my sail consists of 5 NOAA Officers, 5 deck crew, 5 engineers, 4 technicians, 2 stewards and 5 scientists.

NOAA Ship Pisces

NOAA Ship Pisces

Pisces is loaded with science equipment. It has the capability to run acoustic surveys, marine mammal surveys, and various fish surveys. The onboard wet lab is used to process the marine life brought in on trawls, long lines, or bandit reels. In the dry lab, the mission data is stored and processed by the scientists and survey technicians on the ship.  There is a side sample station on the starboard deck where the cameras and ROVs are launched and the trawls are deployed on its stern. The centerboard, on the hull underneath the ship, has mounted sensors that send back various types of data for the scientist to use. This vessel was also engineered to be quiet while underway so it won’t scare marine life. The ship shares the oceanographic, hydrographic and weather data it gathers daily to the outside world.

The Commanding Officer gave me a tour of the bridge.  The bridge is the navigation center. The vessel can be operated from one of four different stations. The science that is being conducted determines where the officer will navigate from. The technology on the bridge is quite amazing.  The dynamic positioning system allows the vessel to stay within certain parameters when supporting science missions. It functions almost like an auto-pilot to keep the ship in the proper position.

NOAA Ship Pisces is like a floating city.   I had the opportunity to explore the engine room with the ship’s first assistant engineer to see how this mini-city works.  He showed me how they process sewage and garbage aboard the vessel. I learned how the vessel creates its own water and power.  I saw the huge engines. This ship has two 8 cylinder engines and two 12 cylinders engines that power the ship. I also learned how the bilge/ballast system keeps the ship stable and how the bow thruster aids in steering

Personal Log

Most of the days pass quickly and I lose track of time.  I can’t believe I have been at sea for 10 days. Having a different type of workday is very unusual to me.  I have taught for almost 18 years so school days are what I know. It is different to work with adults all day instead of children.  It is a definite change of pace. Today is a slow day. We are currently standing-by due to a weather delay. We have moved closer to shore and are riding out the storm.  Hopefully, we will be able to be back up and running tomorrow.

I will surely miss the trips to the galley when I get home. I have probably gained five pounds on this trip. The stewards that cook on this ship do an amazing job.  It is nice to have already prepared meals. I have gotten spoiled by not cooking too. I know will miss the view when I get back to land. Watching the waves never gets old.  I could stare at the water all day. Even when it is stormy the ocean is beautiful.

Being away from home is hard.  It’s difficult not to harass my team teachers about my classroom while I am gone.  I know that my students are well taken care of but it is hard not to worry. The letters from my students, emails from family,  texts from my husband, messages from friends, and sweet videos from my granddaughter help me combat homesickness.

Did You Know?

The Gulf of Mexico is home to 21 marine mammals and 5 sea turtle species

Student questions

How many species of sharks are in the gulf?  There are approximately 49 shark species in the gulf.

Science and Technology Log

This week I have learned a lot about the reef fish studied in this SEAMAP survey. I have learned how to weigh the fish and take various length measurements. I have also learned how to examine the gonads and distinguish a male from a female.  I can now properly remove the otolith bones from the otic capsule that is located at the base of the fish’s skull.

 

We have had some unusual catches that have provided great learning experiences as well.  The bandit reel caught a sharksucker on the line as it returned. This fish belongs to the Remora family.  It attaches to sharks and other marine animals. This was a really unusual creature to observe.

The camera arrays had fireworms hitch a ride to the deck from the bottom of the gulf. These guys look like large spikey caterpillars. They have venom in their bristles that can cause a painful sting.

Personal Log

Today was a beautiful day.  The water is such a beautiful blue.  The sky was cloudless last night so I finally got to look at the stars.  The night sky seems much more vast and bright away from the light pollution on land.  The stars are amazingly bright. I am enjoying life on the ship but I do miss home. I have a greater respect for those that work away from home for long periods of time.  Teamwork and a positive attitude seem to be the lifeblood of this NOAA vessel and that makes it much easier to adjust.

Did You Know?

Many birds will often land on the vessel to rest during their migration route across the Gulf of Mexico.

Questions from students:

Why do scientists need to know what types of fish are on the reef?  

It is important to manage and maintain the reef fish species because they are often over-fished.

Air Temperature: 18.1oC (64.5oF)
Water Temperature: 22.29oC (72oF)
Wind speed: 10.81 knots (12.4 mph)
Conditions: cloudy,  1 to 2 ft seas

Science and Technology Log

The most important equipment on this mission are the camera arrays. Most of the data collected are dependent on these cameras.  I mentioned in my last entry the two types of camera arrays used in this survey are the SatCam and the RIOT.  The video taken from these camera arrays is stitched together in a five-panel single view. The videos are reviewed and each species that appears is counted and recorded.  Images help the scientist determine the population of fish at a given site. The RIOT is a two-stacked spherical camera housing unit that contains 5 horizontal cameras and one upward facing camera.  The RIOT is the more expensive of the two arrays, but it gives the scientist a greater ability to measure fish when they are captured in the dual videos.

Over the past few days, we have caught several species of fish on the bandit reels. We have caught red snapper, vermilion snapper, and red porgy. These lines have 10 baited hooks and they are dropped into the water on a randomly selected site.  In order to obtain a proper sample of the fish, very little human interaction is made with the reel or the line. This leaves out any fisherman bias and allows for natural sampling of species on the site.  The hook sizes are rotated with each drop. The hooks sizes are 8, 11, and 15. If reel 1 starts with size 8 hook, it will have size 11 on the next drop, and then 15 on the third. Each reel has a different rotating pattern.  This allows each hook size to be in the water over the same site. The data will help determine if a certain hook type is favored by a species of fish.

Personal Log

My students will return to school tomorrow from spring break.  I am a little sad I am not there with them.  They wrote letters for me to read while I was away. I have read some of these already and they are pretty funny.  I want to reassure them that I will not fall overboard and that I am eating well.  I will answer student questions on the bottom of my blogs.

We are in the Gulf of Mexico about 70 to 80 miles offshore, on the Mississippi-Alabama Continental shelf.  I have not been this far out in the gulf before today. It is pretty humbling to look out and just see blue water. The sunrises and sunsets are spectacular. You can’t always see them though. The weather has been pretty gloomy the last two days, so I was unable to see last night’s sunset or this morning’s sunrise.   We had a storm yesterday followed by the much cooler weather today.  I hope this is the only cold snap we get.  I am not a fan of cold boat work.

Did You Know?

Turbidity is how cloudy the water is based on the suspended solids. The higher the turbidity the more sediment, algae and other solids are suspended in the water.  Clear water has low turbidity.

Questions from students:

What is hydrography? The science that measures and describes the physical features of bodies of water and land close to these bodies of water.  Multibeam echosounders are used to obtain hydrographic data.

New species that I have seen:  Red Porgy:  Pagrus pagrus

                           Vermilion Snapper:  Rhomboplites aurorubens

Science and Technology Log

I have been aboard Pisces for over 24 hours.  I have learned a lot about the technology used on the ship.  This vessel has a Simrad ME70 multibeam echo sounder. This device will create a bathymetric map of the survey areas that have been randomly selected for this mission.

The crew is on the third leg of a four leg reef fish survey.  This SEAMAP survey will use cameras as its primary instrument to study the population of fish in the survey area. There are two types of camera arrays the scientist use.   The SatCam has 7 cameras that allow a 360-degree view of the ocean floor.  The RIOT is a double-stacked version with 12 cameras. The RIOT allows the same visuals as the SatCam but can also be used for fish measurement.

SatCam ready to deploy

The SatCam and RIOT are rotated, one is deployed each site. The boat is positioned over the sampling site and the cameras are released into the water. The cameras free fall to the bottom and are buoyed. They are left to soak for 30 minutes before they are picked back up.  The camera begins recording 5 minutes after it hits the bottom to allow the sediment to settle, it then records for the remaining 25 minutes.

After the camera is sent into the water, the ship moves away and a CTD is released into the water in much the same way.  The CTD is an electronic instrument package that sends back real-time data of water conditions such as salinity, temperature, density, and light filtration versus water depth.

Bandit reels are also used in this survey.  There are three of these reels mounted on the starboard side of the boat. The line on each has 10 baited hooks.  This leg of the trip we are only fishing every other stop. The first round of fishing with the bandit reels yielded no fish. The second time the stern bandit reel caught silky sharks.  Three sharks made it to the deck to be weighed, measured and then safely released. The next time we used the reels two large red snappers were caught. They were weighed and measured. The otoliths and gonads were removed from each specimen.  These will be used to determine age and reproductive abilities.

I think I am getting adjusted to life aboard the ship. We are only working during daylight hours so I won’t have to change my sleeping schedule. I am working with a team of 4 scientists and they are doing a great job explaining everything and answering my questions. There is so much to learn about and I want to know it all.

I am taking medication to keep from getting seasick and it is working, but I was so exhausted yesterday that I went to bed after watching the sunset.  I hope that will get better in the coming days. I haven’t lost my excitement about being here.  Everything out here is interesting.

Did You Know?

A snapper otolith can tell the age of the fish.  The otolith is an ear bone. When removed from the fish and cut in half, the rings can be counted.

Ocean Springs, MS

Hello from the Mississippi Gulf Coast.  I am a 7th grade science teacher at St. Martin Middle School in Ocean Springs.  This is my 5th year as a St. Martin Yellow Jacket and my 17th year as an educator. I currently teach science to over 100 seventh graders every day.  This is most definitely a challenge, but one I enjoy taking on. Teachers are always looking for ways to improve classroom instruction and grab student interest.  I applied to NOAA’s Teacher at Sea program hoping to accomplish both of those tasks. Because we live so close to the Gulf of Mexico, it is a big part of my students’ lives.  I will use the experience and knowledge I gain at sea to link our curriculum to something they see every day. This will give real value and relevance to the content they learn in class. I have already spent some time explaining my trip and NOAA’s mission to my students.  They are interested and excited about my adventure. Most of them have written questions that they want me to answer in my future blogs. Students, keep checking back to see if your question is posted or just to make sure Mrs. K hasn’t fallen overboard.

I am eager to spend two weeks on the NOAA ship Pisces. I love the Gulf of Mexico and I can’t wait to learn more about it. My husband and I spend every possible weekend, on our on boat usually heading to one of Mississippi’s beautiful barrier islands. We spend most of our vacation days on Gulf beaches and we even got married on the beach in Orange Beach, AL.  IMG_0137[2]

In just a few weeks I will board Pisces in Pascagoula, MS, and join the crew on Leg 3 of a 4 Leg reef fish survey. I will be at sea for 14 days and disembark in Tampa, Florida. I am thrilled I have the opportunity to be on a fishing vessel.  I really enjoy fishing and I love seeing marine life. I feel like this is going to be very interesting and I am excited to do this type of hands-on research.

The next time I write I will be officially at sea. I know it won’t be easy to be away from home.  I will certainly miss my family, friends, and SMMS.  My students wrote me letters to read while I am on the boat to help combat homesickness.  I can’t wait to read them.  I am very grateful for the opportunity to take this trip and I look forward to sharing what I am learning along the way.

Don’t forget to check back in 13 days.

Did You Know?

The Pisces has a multi-beam echo sounder (MBES) that allows scientist to measure and count fish by the reflection of sound off their bodies. It projects a fan-shaped beam of sound that can also be used to map the seafloor.
