Personal Log
The last days of the survey cruise followed a pattern similar to the first days. Everyone got into the schedule of working 12-hour shifts and everyone accepted their role and responsibilities as a member of the team.
We all (morning and night shifts) ate dinner together and often (if there were no stations to be sampled) sat together to play board games, such as Chinese checkers.

We also all watched the sunsets together — each one was spectacular!

On the night of August 6th, we were towing the Neuston net through an area that had so many jellyfish that we could not lift the net out of the water. We had to get another net to help lift the heavy load. We all took bets to see how many jellyfish we had caught. I bet 15 jellyfish, but I was way off — there were over 50 jellyfish in the net! There were so many, that as we were counting them, they began to slide off the deck and back into the water. I have a great video that I cannot wait to share with you in September!

The ship arrived back in Miami on Sunday night around 7:30pm. It was amazing how quickly everyone unloaded the scientific equipment and started to go their separate ways. Because the NOAA building (Atlantic Oceanographic and Meterological Laboratory, AOML) is located right across the street from where the Walton Smith docks, we loaded all of the equipment into a truck and delivered it to the AOML building.
This was great because I got a quick tour of the labs where Lindsey, Nelson and others run the samples through elaborate tests and computer programs in order to better understand the composition of the ocean water.

In reflecting upon the entire experience, I feel extremely fortunate to have been granted the opportunity of a lifetime to participate in Teacher at Sea. I was able to help with all aspects of the scientific research from optics, to chemistry, to marine biology as well as help with equipment that is usually reserved for the ship’s crew, such as lowering the CTD or tow nets into the water.
There were many moments when I felt like some of my students who are struggling to learn either English or Spanish. There are a lot of scientific terms, terms used to describe the equipment (CTD and tow net parts), and basic boat terminology that I had not been exposed to previously. I am thankful that all of the members of the cruise were patient with my constant questions (even when I would ask the same thing 3 or 4 times!) and who tried to explain complex concepts to me at a level that I would understand and be able to take back to my students.
I am using the GER 1500 spectroradiometer
It makes me reflect again on everything I learned during my MEd classes in Multicultural/Multilingual Education — a good educator empowers students to ask questions, take risks, ask more questions, helps students access information at their level, is forever patient with students who are learning language at the same time that they are learning new concepts, provides plenty of hands-on experiments and experiences so students put into practice what they are learning about instead of just reading or writing about it.
A porthole on the R/V Walton Smith
As we sailed into Miami, a bottlenose dolphin greeted us – sailing between the two hulls of the catamaran and coming up often for air. It was so close, that I could almost touch it! Even though I was sad that the survey cruise was over, it was as though the dolphin was welcoming me home and on to the next phase of my Teacher at Sea adventure: I return to the classroom in September loaded with great memories, anecdotes, first hand-experiences, and a more complete knowledge of oceanography and related marine science careers to help empower my students so that they consider becoming future scientists and engineers. Thank you Teacher at Sea!

Science and Technology Log
Many of you have written comments asking about the marine biology (animals and plants) that I have seen while on this cruise. Thank you for your posts – I love your questions! In today’s log, I will talk about the biology component of the research and about the animals that we have been finding and documenting.
We have another graduate student aboard, Lorin, who is collecting samples of sargassum (a type of seaweed).
Sargassum sample from Neuston net tow
There are two types of sargassum. One of those types usually floats at the top of the water and the other has root-like structures that help it attach to the bottom of the ocean.
Lorin is filtering a sample from the Neuston net in the web lab
We are using a net, called a Neuston net, to collect samples of sargassum that float. The Neuston net is towed alongside the ship at the surface at specific stations. This means that the ship drives in large circles for 30 minutes which can make for a rocky/dizzy ride – some of the chairs in the dry lab have wheels and they roll around the floor during the tow!
Towing the Neuston net along the side of the ship
Lorin and other researchers are interested in studying sargassum because it provides a rich habitat for zooplankton, small fish, crabs, worms, baby sea turtles, and marine birds. It is also a feeding ground for larger fish that many of you may have eaten, such as billfish, tuna, and mahi mahi.
Small crab that was living in the sargassum
The net not only collects sargassum, but also small fish, small crabs, jellyfish, other types of seaweed, and small plankton.
Small fish from the Neuston net
Plankton can be divided into two main categories: zooplankton and phytoplankton. As I said in my last post, phytoplankton are mostly very small plants or single-celled organisms that photosynthesize (they make their own food) and are the base of the food chain. Zooplankton are one level up on the food chain from phytoplankton and most of them eat phytoplankton. Zooplankton include larva (babies) of starfish, lobster, crabs, and fish.
Small zooplankton viewed through the dissecting microscope
We also use a Plankton net to collect samples of plankton. This has a smaller mesh, so it collects organisms that are so small they would fall through the Neuston net. Scientists are interested in studying the zooplankton that we catch in the Plankton net to understand what larger organisms might one day grow-up and live in the habitats we are surveying. They study the phytoplankton from the Plankton net to see what types of phytoplankton are present in the water and in what quantities.
Washing off the Plankton net
Today we collected so many diatoms (which are a type of phytoplankton) in the Neuston net that we could not lift it out of the water! This tells us that there are a lot of nutrients in the water (a diatom bloom) – maybe even harmful levels. I am bringing some samples of the diatoms and zooplankton home with me so we can look at them under the microscopes at school!
Evidence of a diatom (phytoplankton) bloom in the Gulf of Mexico
The marine biologists on this cruise are mainly interested in looking at phytoplankton and zooplankton, but we also have seen some larger animals. I have seen many flying fish skim across the surface of the water as the boat moves along. I have also seen seagulls, dolphins, sea turtles, cormorants (skinny black seabirds with long necks), and lots of small fish.

Personal Log
Working as an oceanographer definitely demands flexibility. I have already mentioned that we chased the Mississippi River water during our second day. After collecting samples, we had to find blue water (open ocean water) to have a control to compare our samples against. We traveled south through the night until we were about 15 miles away from Cuba before finding blue water. All of this travel was in the opposite direction from our initial cruise plan, so we have had to extend our cruise by one day in order to visit all of the stations that we need to visit inside the Gulf of Mexico. This has meant waking-up the night shift so we can all change their airplane tickets and looking at maps to edit our cruise plan!
Changes to our cruise plan on the survey map
Many of you are writing comments about sharks – I have not seen any sharks and I will probably not see any. The chief scientist, Nelson, has worked on the ocean for about 33 years and he has sailed for more than 1,500 hours and he has only seen 3 sharks. They mostly live in the open ocean, not on the continental shelf where we are doing our survey. If there were a shark nearby, our ship is so big and loud that it would be scared away.
Playing with syringodium
Today I saw a group of about 4 dolphins off the side of the ship. They were pretty far away, so I could not take pictures. Their dorsal fins all seemed to exit the water at the same time – it was very beautiful. A member of the crew spotted a sea turtle off the bow (front) of the ship and I saw several different types of sea birds, especially seagulls.
Yesterday afternoon we passed through the Gulf of Mexico near the Everglades and there were storm clouds covering the coastline. The crew says that it rains a lot in this part of the Florida coast and that Florida receives more thunderstorms than any other state. It is strange to me because I always think of Florida as “the sunshine state.”
Grey sky and green water in the Gulf of Mexico
The color of the ocean has changed quite a lot during the cruise. The water is clear and light blue near Miami, clear and dark blue farther away from the coast in the Atlantic Ocean, cloudy and yellow-green in coastal Gulf of Mexico, and cloudy and turquoise in the Florida Bay. Scientists say that the cloudiness in coastal Gulf of Mexico is caused by chlorophyll and the cloudiness in the Florida Bay is caused by sediment.
It has been hot and sunny every day, but the wet lab (where we process the water samples and marine samples), the dry lab (where we work on our computers), the galley and the staterooms are nice and cool thanks to air conditioning! I can tell that I am getting used to being at sea because now when we are moving, I feel as though we are stopped. And when we do stop to take measurements, it feels strange.

Science and Technology Log
As I said yesterday, the oceanographic work on the boat basically falls into three categories: physical, chemical and biological. Today I will talk a bit more about the chemistry component of the work on the R/V Walton Smith. The information that the scientists are gathering from the ocean water is related to everything that we learn in science at Key – water, weather, ecosystems, habitats, the age of the water on Earth, erosion, pollution, etc.
First of all, we are using a CTD (a special oceanographic instrument) to measure salinity, temperature, light, chlorophyll, and depth of the water. The instrument on this boat is very large (it weights about 1,000 lbs!) so we use a hydraulic system to raise it, place it in the water, and lower it down into the water.
Lindsey takes a CO2 sample from the CTD
The CTD is surrounded by special niskin bottles that we can close at different depths in the water in order to get a pure sample of water from different specific depths. Nelson usually closes several bottles at the bottom of the ocean and at the surface and sometimes he closes others in the middle of the ocean if he is interested in getting specific information. For each layer, he closes at least 2 bottles in case one of them does not work properly. The Capitan lowers the CTD from a control booth on 01deck (the top deck of the boat), and two people wearing a hard hat and a life vest have to help guide the CTD into and out of the water. Safety first!
Once the CTD is back on the boat, the chemistry team (on the day shift, Lindsey and I are the chemistry team!) fills plastic bottles with water from each depth and takes them to the wet lab for processing. Throughout the entire process, it is very important to keep good records of the longitude and latitude, station #, depth of each sample, time, etc, and most importantly, which sample corresponds to which depth and station.
We are taking samples for 6 different types of analyses on this cruise: nutrient analysis, chlorophyll analysis, carbon analysis, microbiology analysis, water mass tracers analysis and CDOM analysis.
The nutrient analysis is to understand how much of each nutrient is in the water. This tells us about the availability of nutrients for phytoplankton. Phytoplankton need water, CO2, light and nutrients in order to live. The more nutrients there are in the water, the more phytoplankton can live in the water. This is important, because as I wrote yesterday – phytoplankton are the base of the food chain – they turn the sun’s energy into food.
Sampling dissolved inorganic carbon
That said, too many nutrients can cause a sudden rise in phytoplankton. If this occurs, two things can happen: one is called a harmful algal bloom. Too much phytoplankton (algae) can release toxins into the water, harming fish and shellfish, and sometimes humans who are swimming when this occurs. Another consequence is that this large amount of plankton die and fall to the seafloor where bacteria decompose the dead phytoplankton. Bacteria need oxygen to survive so they use up all of the available oxygen in the water. Lack of oxygen causes the fish and other animals to either die or move to a different area. The zone then becomes a “dead zone” that cannot support life. There is a very large dead zone at the mouth of the Mississippi River. So we want to find a good balance of nutrients – not too many and not too few.
The chlorophyll analysis serves a similar purpose. In the wet lab, we filter the phytoplankton onto a filter.
I am running a chlorophyll analysis of one of the water samples
Each phytoplankton has chloroplasts that contain chlorophyll. Do you remember from 4th grade science that plants use chlorophyll in order to undergo photosynthesis to make their own food? If scientists know the amount of chlorophyll in the ocean, they can estimate the amount of phytoplankton in the ocean.
Carbon can be found in the form of carbon dioxide (CO2) or in the cells of organisms. Do you remember from 2nd and 4th grade science that plants use CO2 in order to grow? Phytoplankton also need CO2 in order to grow. The carbon dioxide analysis is useful because it tells us the amount of CO2 in the ocean so we can understand if there is enough CO2 to support phytoplankton, algae and other plant life. The carbon analysis can tell us about the carbon cycle – the circulation of CO2 between the ocean and the air and this has an impact on climate change.
The microbiology analysis looks for DNA (the building-blocks of all living organisms – kind of like a recipe or a blueprint). All living things are created with different patterns or codes of DNA. This analysis tells us whose DNA is present in the ocean water – which specific types of fish, bacteria, zooplankton, etc.
The water mass tracers analysis (on this boat we are testing N15 – an isotope of Nitrogen, and also Tritium – a radioactive isotope of Hydrogen) helps scientists understand where the water here came from. These analyses will help us verify if the Mississippi River water is running through the Florida Coast right now. From a global viewpoint, this type of test is important because it helps us understand about the circulation of ocean water around the world. If the ocean water drastically changes its current “conveyor belt” circulation patterns, there could be real impact on the global climate. (Remember from 2nd and 3rd grade that the water cycle and oceans control the climate of Earth.) For example, Europe could become a lot colder and parts of the United States could become much hotter.
This is an image of the conveyor belt movement of ocean currents
The last type of analysis we prepared for was the CDOM (colored dissolved organic matter) analysis. This is important because like the water mass tracers, it tells us where this water came from. For example, did the water come from the Caribbean Sea, or did it come from freshwater rivers?
I am coming to understand that the main mission of this NOAA bimonthly survey cruise on the R/V Walton Smith is to monitor the waters of the Florida Coast and Florida Bay for changes in water chemistry. The Florida Bay has been receiving less fresh water runoff from the Everglades because many new housing developments have been built and fresh water is being sent along pipes to peoples’ houses. Because of this, the salinity of the Bay is getting higher and sea grass, fish, and other organisms are dying or leaving because they cannot live in such salty water. The Bay is very important for the marine ecosystem here because it provides a safe place for small fish and sea turtles to have babies and grow-up before heading out to the open ocean.
Personal Log
This cruise has provided me great opportunities to see real science in action. It really reinforces everything I tell my students about being a scientist: teamwork, flexibility, patience, listening and critical thinking skills are all very important. It is also important to always keep your lab space clean and organized. It is important to keep accurate records of everything that you do on the correct data sheet. It can be easy to get excited about a fish or algae discovery and forget to keep a record of it, but that is not practicing good science.
It is important to keep organized records
It is also important to stay safe – every time we are outside on the deck with the safety lines down, we must wear a life vest and if we are working with something that is overhead, we must wear a helmet.
I have been interviewing the scientists and crew aboard the ship and I cannot wait to return to Arlington and begin to edit the video clips. I really want to help my students understand the variety of science/engineering and technology jobs and skills that are related to marine science, oceanography, and ships. I have also been capturing videos of the ship and scientists in action so students can take a virtual fieldtrip on the R/V Walton Smith. I have been taking so many photos and videos, that the scientists and crew almost run away from me when they see me pick up my cameras!

The food continues to be wonderful, the sunsets spectacular, and my fellow shipmates entertaining. Tomorrow I hope to see dolphins swimming alongside the ship at sunrise! I will keep you posted!!
Did you know?
The scientists and crew are working 12-hour shifts. I am lucky to have the “day shift” which is from 8am to 8pm. But some unlucky people are working the “night shift” from 8pm to 8am. They wake-up just as the sun is setting and go to sleep right when it rises again.
Animals seen today…

– Many jellyfish
– Two small crabs
– Lots of plankton

Science and Technology Log
The oceanographic work on the boat can be divided into three categories: physical, chemical, and biological. In this log, I will explain a little bit about the part of the research related to the physics of light. Upcoming 5th graders – pay attention! We will be learning a lot about light in January/February and it all relates to this research project.
Brian and Maria are two PhD students who are working with the physical components. They are using several optical instruments: the SPECTRIX, the GER 1500, the Profiling Reflectance Radiometer (PRR), and the Profiling Ultraviolet Radiometer (PUV).
Brian and Maria take optic measurements with the SPECTRIX and GER 1500
The SPECTRIX is a type of spectroradiometer that measures the light coming out of the water in order to understand what is in the water. For example, we can measure the amount of green light that is reflected and red and blue light that is absorbed in order to get an idea about the amount of chlorophyll in the water. This is important because chlorophyll is the biggest part of phytoplankton and phytoplankton are tiny plant-like algae that form the base of the food chain on Earth.
Brian lowers PRR into the water
The PRR and the PUV measure light at different depths to also understand what is in the water and at what depth you will find each thing in the water. The light becomes less bright the further down you go in the water. Most of light is between 0-200 meters of depth. The light that hits the water also becomes less bright based upon what is in the water. For example, you might find that chlorophyll live at 10 meters below the surface. It is important to understand at what depth each thing is in the water because that tells you where the life is within the ocean. Most of the ocean is pitch-black because it is so deep that light cannot penetrate it. Anything that lives below the light level has to be able to either swim up to get food, or survive on “extras” that fall below to them.
Personal Log
These few days have been very fun and action-packed! I arrived on the ship on Sunday afternoon and helped Nelson and the crew get organized and set-up the stations for the cruise. Several other people had also arrived early – two graduate students who are studying the optics of the water as part of their PhD program, one college student and one observer from the Dominican Republic who are like me – trying to learn about what NOAA does and how scientists conduct experiments related to oceanography.
On Monday morning, we gathered for a team meeting to discuss the mission of the cruise, introduce ourselves, and get an updated report on the status of the Mississippi River water. It turns out that the water is going in a bit of a different direction than previously projected, so we will be changing the cruise path of the ship in order to try to intersect it and collect water samples.
I am helping lower the CTD into the water
Monday we all learned how to use the CTD (a machine that we use to collect samples of water from different depths of the ocean) and other stations at the first several stops. It was a bit confusing at the beginning because there is so much to learn and so many things to keep in mind in order to stay safe! We then ate lunch (delicious!) and had a long 4-hour ride to the next section of stops. When we arrived, it was low tide (only 2 ft. of water in some places) so we could not do the sampling that we wanted to do. We continued on to the next section of stops (another 3 hour ride away!), watched a safety presentation and ate another delicious meal. By this time, it was time for the night shift to start working and for the day shift to go to bed. Since I am in the day shift, I was able to sleep while the night shift worked all night long.
Today I woke up, took a shower in the very small shower and ate breakfast just as we arrived at another section of stops. I immediately started working with the CTD and on the water chemistry sampling. We drove through some sea grass and the optics team was excited to take optical measurements of the sea grass because it has a very similar optical profile to oil. The satellites from space see either oil or sea grass and report it as being the same thing. So scientists are working to better differentiate between the two so that we can tell sea grass from oil on the satellite images. The images that Maria and Brian took today are maybe some of the first images to be recorded! Everyone on the ship is very excited!
Several hours later, we came to a part of the open ocean within the Florida Current near Key West where we believe water from the Mississippi River has reached. Nelson and the scientific team believe this because the salinity (the amount of dissolved salt) of the surface water is much lower than it normally is at this time of year in these waters. Normally the salinity is about 36-36.5 PSUs in the first 20 meters and today we found it at 35.7 PSUs in the first 20 meters. This may not seem like a big difference, but it is.
The water from the Mississippi River is fresh water and the water in the Florida Keys is salt water. There is always a bit of fresh water mixing with the salt water, but usually it is not enough to really cause a change in the salinity. This time, there is enough fresh water entering the ocean to really change the salinity. This change can have an impact on the animals and other organisms that live in the Florida Keys.
Additionally, the water from the Mississippi River contains a lot of nutrients – for example, fertilizers that run off from farms and lawns into gutters and streams and rivers – and those nutrients also impact the sea life and the water in the area. Nelson says that this type of activity (fresh water from the Mississippi River entering the Florida Current) occurs so infrequently (only about ever 6 years), scientists are interested in documenting it so they can be prepared for any changes in the marine biology of the area.
For all of these reasons and more, we took a lot of extra samples at this station. And it took almost 2 hours to process them!
In the evening, we stopped outside of Key West and the director of this program for NOAA, Michelle Wood, took a small boat into the harbor because she cannot be with us for the entire cruise.
Sunset over Key West - a beautiful way to end the day
She asked me if I’d like to go along with the small boat to see Key West, since I have never been there before, and of course I agreed! I got some great pictures of the R/V Walton Smith from the water and we saw a great sunset on the way back to the ship after dropping her off with Jimmy Buffet blasting from the tourist boats on their own sunset cruises.
We will be in the Mississippi River plume for most of tonight. Everyone is very excited and things are pretty crazy with the CTD sampling because we are doing extra special tests while we are in the Mississippi River plume. We might not get much sleep tonight. I will explain in my next blog all about the chemistry sampling that we are doing with the CTD instrument and why it is so important.
Did you know?
On a ship, they call the kitchen the “galley,” the bathroom is the “head,” and the bedrooms are called “staterooms.”
One interesting thing about the ship is that it does not have regular toilets. The ship has a special marine toilet system that functions with a vacuum and very thin pipes. If one of the vacuums on one of the toilets is not closed, none of the toilets work!
Animals seen today…
Zooplankton that live in the sargassum (a type of seaweed that usually floats on the water) –baby crab, baby shrimp, and other zooplankton. The sargassum is a great habitat for baby crab, baby shrimp, and baby sea turtles.

Personal Log
Hola! My name is Caitlin Fine and I teach science at Escuela Key (Francis Scott Key School), a dual-language immersion elementary school in Arlington, VA. I am a Virginia native and my heart is constantly torn between the lively activities of the Washington, D.C. area and the peaceful beauty of the Shenandoah Valley. I left Virginia for college and graduate school, but returned 4 years ago to begin my teaching career for Arlington County Public Schools.
On top of Aspen Mountain during a recent trip to Colorado
Although I majored in Political Science and Spanish Literature and I have graduate degrees in Spanish Literature and Multicultural Education, I have always been interested in science. During college, I worked on an organic farm in Andalucia, Spain that practiced permaculture (this is a way of using the land that is sustainable so that the soil does not use-up all of its nutrients). I also traveled around the Southern Cone of South America (Chile, Argentina, Peru, Bolivia, Brazil) studying the geology of the region. As you can see, I have some experience with farming and the mountains. But I have never really spent an extended time at sea — I have never slept on a boat or studied the marine ecosystems up close and personal over a period of time. I hope that I am not seasick!
My interest in science mixed with my love of cooking has created a current obsession — the health of our national and global food and water supplies. Did you know that every time we take medicine or use pesticides on our plants, a small amount of it enters the water supply and some of it ends up in the rivers and oceans nearby where fish and water plants are trying to live?
The science program at Key is a bit different from traditional elementary schools in that there are three science teachers who teach all 630 students. For the past two years, I have taught the Kindergarteners, the 2nd graders and half of the 5th graders. Key kids are amazing scientists — they are full of questions about how the world works and they are not afraid to get busy trying to figure things out on their own through hands-on inquiry and cooperative learning. I cannot wait to return to Key with new knowledge of oceanography, ocean-related careers and ways to monitor the health of the ocean to share with my students and colleagues!
I am so excited to be a Teacher at Sea for the National Oceanic and Atmospheric Administration‘s 2011 Field Season! Teacher at Sea is a program that provides allows Kindergarten through college-level teachers to live and work alongside scientists on research and survey ships. The goal of the program is to help teachers understand our ocean planet, environmental literacy, and maritime work so that they can return to the classroom and share information with their students about what it is like to be a real scientist who studies the ocean.
I will be on a 5-day cruise on the R/V Walton Smithin south Florida.
This is the R/V Walton Smith
From what I understand, we will be taking measurements across the south Florida coastal marine ecosystem (the southwest Florida shelf, Biscayne and Florida Bays, and the Florida Keys reef tract). The program is important because the research has helped scientists keep an eye on the sensitive marine habitats, especially when the ecosystem has had to deal with extreme events, such as hurricanes, harmful algal blooms or potential oil spill contaminants. We will test the circulation, salinity, water quality and biology of the ecosystem.
The currents might move some of the Mississippi River water toward south Florida
During this cruise, I have been told that we might be able to measure Mississippi River water because it might enter our survey track.
Scientists are also going to be trying out new optical measurement tools! It sounds as though I will have a lot to report back to you about!
Please leave me a comment or any questions you have about the cruise.
