Science and Technology Log

Some of you are about to begin your day, and mine is dragging on for a little while more. Today was a bit more full of wind and rain than yesterday. In fact, the seas have heightened to the point that we are in a continual state of bouncing back and forth like a ping-pong ball (or a rag doll, if you prefer the cliché). That would be ok if we were in fact a ping-pong ball. Instead, we are a 240-foot steel sailing vessel. The Pacific has definitely had her way with us today. Although we are all still healthy and the Sette continues to push back on the waves crashing at the bow just as hard as they are pushing on Her. Tomorrow is bound to be substantially worse than today according to preliminary weather reports from the bridge (remember, we are NOAA, the weather source!). As the French say… Yeah I caught myself before I quoted the French! The only French person worth quoting is Napoleon, who himself claims that he was not French! (I am only harassing France because Carole, one of our researchers, is French and I have not given her a hard time in my journals yet! I was treated very well by the French when I was in France, and I am also hoping to one day work with a man whose last name is Cousteau, so I better be kind to the French!)

I got to sleep in a little longer as the “runner” today than the last two days when I was a “cracker” and bait cutter. Having this job didn’t keep me any drier than the crackers. Nor did it keep me very far away from the smell of day old festering mackerel. But it was a nice change. Tomorrow I go back to my favorite job- that of a stacker. Being a stacker keeps me as far away from the science of this mission as possible. It puts me on the fantail with good music and good crew to keep me company. If you can’t tell, these two things have become some of my favorite aspects of the cruise. But now I am sounding redundant of past entries.

Today we lost eight more traps to the coral reef below. Good for it! Except that those traps will be there for some time. It is kind of ironic the way this mission and the next will work out for the Oscar Sette. On the next cruise, the Sette will be hosting scientists specializing in coral reef protection. Perhaps we should have their chief scientist and our chief scientist talk next time before anyone goes out to sea. Then maybe we wouldn’t tear down the bridges that they keep building!

Bob says that fishermen have a saying about losing gear to the sea: If you put it in, do not expect to get it back. I’ve thought about it all day long, a kind of sailor’s koan, and have only been able to conclude that fishermen who think this must have very little respect for the sea. But that is not my position to say. As a wise man has advised me, some battles are best not fought. The sad reality of this trip is that despite how much effort we put into protecting any or all species of marine animals, someone in some part of the world is doing his part to remove as many of those animals as possible to put as much money in his pocket as possible. Again, no negativity. Only reality.

On the lighter side of things, I found enjoyment in two particular marine species today. The first was a monk seal that passed by the port side (left side) of the ship between hauling strings of traps. It didn’t stop to give us much of a show, which is good because that is not its purpose in life. Instead it just dipped itself into the waves and moved on past the stern (rear) of the ship and out of sight.

The second was an albatross that didn’t seem to mind the fact that the wind picked up to about 30 knots today. In fact, it took advantage of this wind to perform some acrobatic maneuvers that I am sure any pilot would love to imitate in any aircraft. At times I swore that its wing tips were in the crest of a wave as it raced about just above the waves. It couldn’t have been more than six inches above the water at times. Which is remarkable because the waves were so sporadic an unequal in size that I expected it to wipe out at any point. Just when it seemed the albatross was going to crash into the water, it would tilt itself upwards and rise into the sky cutting the sky into two pieces as quickly as a warm knife through butter. The flight was so graceful and perfect in its form. As cliché as it sounds, I thought of how wonderful it must be to be that albatross today. It didn’t seem to be scavenging for food or drink. And it never seemed anxious that it was lost. It was just playing in the wind and waves, perhaps taking a day off of the trials of yesterday and the worries of tomorrow. Perhaps it too can say mooo!

Mission: Hydrographic and Fish Habitat Survey
Geographic Area: Alaska
Date: June 14, 2006

Science and Technology Log

Today the crew worked on deploying several devices that work to collect information about the ocean floor. Together with the fisheries department, the FAIRWEATHER is able to gather information about the layout of the ocean floor and the substrate itself which helps them better understand what type of fish live in what area and what kind of habitat they prefer. For example, it may be known that a certain fish whose existence may be threatened and protected lives in a specific area. Therefore it is important to protect that area. With the new information that is being collected, we can tell what the bottom habitat looks like and then also work to protect not just specific locations in the water, but also specific habitats.

This large torpedo-like device is called a towfish. It is dropped into the water behind the ship to collect pictures of the ocean floor. Teacher at Sea Lisa Kercher assists in bringing it back to deck.

Personal Log

I was able to help in deploying and retrieving several of the instruments used today. While it was cold and rainy, the learning experience outweighed the negatives in the climate. It is great to be out learning what goes on in the research aspect of the science field, rather than just within the classroom!

The penetrometer has been deployed into the water to collect information about the consistency of the ocean floor.

Question of the Day

I was told that there were many sea otters surrounding the ship last night. The water was also full of kelp. Why might the two of these organisms be found in the same location of the water at the same time?

The coffee pot. See the ring to keep the coffee from flying when the seas get rough?

A lot of you have been asking about the food on ship. How do we eat? What do we eat? Where do we get our food. All of these are great questions, so yesterday I spent some time with Chief Cook Russell Van Dyke to get some answers for you. He, along with the Chief Steward and the Second Cook, is responsible for preparing all the meals on NOAA Ship MILLER FREEMAN.

How do people eat on a ship? “With a knife and fork,” said our chief cook with a smile. Food is prepared and served on the ship in much the same way that you prepare and serve food athome. The main difference is quantity. Here on the ship, food is prepared for 40 people instead of just a few. “We don’t cook one, chicken, like you do at home,” said Mr. Van Dyke, “we cook 5 chickens. Here are some pictures of where the food is cooked, and where the food is served. On a ship, this is called the galley. Can you see the ring around the coffee pot? Can you guess what that is for? During storms at sea, when the waves are high, that ring keeps hot coffee from flying around the galley. Good idea!

Another interesting difference between food on a ship and food at home is that when you are out to see for a month, you cannot run down to the corner to get some milk if you run out. Each time NOAA Ship MILLER FREEMAN is in port, it must take on enough food to last for the entire journey to come. How do they keep all that food? Aside from being a great cook, Mr. Van Dyke and the rest of the crew are also experts in how to store food and keep it from going bad. NOAA Ship MILLER FREEMAN has not one but three refrigerators and two freezers. The refrigerators are kept at slightly different temperatures. The dairy products, like milk and cheese are kept at 37 degrees . The fruits and vegetables are kept in a separate refrigerator at 42 degrees. They keep the humidity in that refrigerator higher as well. Those slightly different conditions help keep the food fresh for a longer period. Meats and ice cream are kept frozen. Dry foods, like cereal are kept in a separate area. Put it all together and the crew on board eat great meals every day. The photo here shows the inside of one of the refrigerators.

How do you cook on board a ship?

Does the crew have a favorite food?

One more question: Does the crew eat split pea soup? There is a superstition among mariners that cooking split pea soup will bring on a storm. I asked Mr. Van Dyke about it. He told me they eat it all the time. This brave crew last had “storm soup” on May 27th and we may have it again in a few days. I guess the only thing they can’t do on board this ship at sea is have a pizza delivered.

Science Log

We continue surveying pollock and surveying birds as we move along the transact lines in the Bering Sea. Most of the surveying is being done with the echosounder, but from time to time, we put the nets into the water and trawl for fish. This helps the scientists know more detail about the fish they see on the echosounders. The nets on NOAA Ship MILLER FREEMAN work basically the same way that nets on large commercial trawlers work. We just catch far fewer fish. Would you like to learn more? Click here for a video on the nets.

Question of the Day:

How much wire would the ship need to let out if it wanted to put the nets 200 feet below the surface? Make sure to watch the video on nets before you try to answer the question.

Answer to Yesterday’s Question:

Look at the speed of the ship on this website: About how far would it go in 24 hours? To get your answer, you should multiply the speed you see by 24. Remember to express your answer in nautical m iles. At the moment, the ship is going about 12 nautical miles per hour. At that speed it will travel about 288 miles per day. The real figure will vary because of winds and currents that effect our speed, and because we sometimes stop to fish.

Answers to Your Questions:

I also had an email request from Marcelo for photos with Rusty and I. Here is one. I’m also putting a second photo on to show you one of Rusty’s favorite games. There is a mail slot in the door to the office where he spends a good part of his day. He loves to stick his paw through and introduce himself to passersby. Surprise!!

Mrs. McBride, thanks for your kind words.

Science and Technology Log

Today was the longest day of hauling traps since we have been out here. I guess that is partly due to the fact that the wind picked up this morning and made the ocean very choppy. We have been experiencing swells of around 5 feet for the last few days. But with the wind cutting into them, the waves smashing into the boat have the strength of the swells but the misdirection of a thousand firecrackers. It made navigating the ship very difficult for the bridge. If our winch (Yes, the Captain corrected me on my use of the word “wench” in a previous entry. A “wench,” he said was a servant girl of the Dark Ages. A “winch” is a machine used to haul lines up and down.) receives the trap strings at angles larger than about 30 degrees to the ship, it is very difficult to use.

A second reason why we had such difficulty hauling the traps this morning is that we set them on coral heads at the bottom of the ocean. The traps are made of sturdy, yet flexible plastic and are connected to each other with rope about a half inch in diameter. Further, there is a fair amount of rope between each trap, which is left to float and dangle in the current, frequently catching itself in the coral and making our job of hauling the traps to the ship extremely difficult.

Twice today the coral won decisive battles against us, and forced the rope to break. We lost a total of 7 traps to the ocean. Bob says that this is a minor loss. I wonder what is to become of the traps once we are gone. Yesterday we lost 9 traps while setting them because instead of attaching a float to the end of a string of eight, a crewmember attached a ninth trap. Instead of having a buoyant float to mark the string of eight traps, nine traps sank quickly to the ocean floor. There was talk this morning of diving the site to retrieve the floats. Then there was talk that the traps were expendable, and that the risk of shark attack was slightly too high. So after today, there are 16 traps on the bottom of the Pacific, full of bait, lobster, sharks, hermit crabs, eel, or anything else that had the misfortune to crawl inside.

I am still greatly enjoying the people. And the sunsets here have been some of the most amazing things that I have ever seen. Even the “full” moon rising the last few nights has left me in pure awe of the world and all its wonders. Last night, while sitting on the deck outside of the bridge, Sarah, an Ensign officer, showed me the Southern Cross rising in the horizon. She also pointed out several other series of constellations that I had never been aware of before. My father warned me about the beauty of the stars in the open sea. He was certainly right. Constellations that I could never begin to see back home in Jacksonville stuck out in the night sky like the ancient sailors’ visions of old. But even with all of the constant beauty of nature around me, I still wake up each morning with apprehension over what my work will bring.

I must move forward, regardless of how I feel towards the science–or rather methodology of the science. And maybe that is what I am supposed to learn through practice over the next three weeks. Usually when I run into something that tastes bitter at first bite, I back away from a second bite. I cannot back away from future bites in this situation. So I will be forced to move into a new realm of patience, perseverance, understanding, and personal growth. I have already given up on the thought of eating fish and lobster anytime soon. Lobster has never been a favorite of mine, but after spending the last four days staring into their fearful little eyes while I pull them from traps, or spread them across a table to take measurements, I have come to love the lobsters for their simple, yet perfect existence.

I hate reaching this point, where I feel as though I am guilty for being part of the human race. I am not about to make such a leap as in Walden, and presume that humans are supposed to act in such a small part in nature as everything else. I know that there is something special about us that gives us the right, perhaps out of desire rather than necessity, to remain at the “top” of the food chain…for now (I say “top” because as soon as I fall into the water during shark feeding time, I guarantee I am NOT at the top of the food chain anymore!). Still I feel as though part of this mission is to see how the lobsters live without the interaction and interference of man in their natural habitat. Then we come along in our ship with our traps and our scientific instruments and rip them from their homes, probe about them for a while, throw them into a bucket with so many of their likes that they would probably not have ever come across on the ocean floor had we not caught them in our traps, toss them back into the sea in a different location from where we pulled them, and then expect them to grow and multiply. I am sorry for the analogy, but in the tradition of practicing perception from different perspectives on this cruise, as I was probing lobsters in the wet lab yesterday I kind of felt like I was an alien in a space ship scooping up human beings, performing horrific torture on them as I took my measurements, and then throwing them back down. In a sick kind of way, I hope that aliens do come along some day (if they haven’t come already) and abduct some of our scientists. I don’t mean them any harm, but sometimes I feel very guilty for our egocentric belief that we can are supposed to analyze and break down everything in order to “fix” nature.

I am afraid that I am getting a little deep in my thought, and it’s not yet time for sunset (my drug of choice for inspiration while onboard the ship). I think that there are a lot of things in nature that we can seek to understand. But I think that we should take hint after hint from Mother Nature as she continues to bombard us with hurricanes in the Atlantic, volcanoes in Indonesia, and the melting of the icecaps in Greenland and Antarctica (and so on, and so forth of course!). Yes, it is truly wonderful to be a human being instead of a fat moo-cow! Do not get me wrong about that! But maybe a fat moo-cow doesn’t suffer so much as it goes about its life because it never thinks that it can control the type or amount of grass it eats, the temperature in which it lows each night, the cleanliness of the water that it drinks, and so forth. It just does what it is created to do, and offers its life as a perfect sacrifice to the Great Beyond by doing this most simple task to the best of its ability.

Visibility: Fair to poor
Wind direction: ESE
Average wind speed: 7 knots
Wave height: 1-2’ SE
Air temperature: 75^oF
Sea temperature: 79^oF
Cloud cover: 100%
Barometric pressure: 10144 mb

Mark Silverman and Nancy McClintock conclude their awesome adventure. My memories truly will last a lifetime and I thank NOAA for giving me the opportunity to participate in this excellent program.

Science and Technology Log

The FREEDOM STAR traveled approximately 200 miles during the night toward Port Canaveral, our final destination. Wave height increased and then decreased as morning arrived. It will take approximately 15 minutes to go through the lock and then 1-½ hours to travel upriver to the dock at Hanger AF. The FREEDOM STAR is the sister ship of the LIBERTY STAR and they are both used in the recovery of rocket boosters for the NASA Space program. Before leaving the dock, the FREEDOM STAR takes on freshwater that is stored in two tanks totaling 17,000 gallons – this is non-potable water. 5,000 gallons of potable (drinkable) water is stored in a separate tank. Once the FREEDOM STR reaches the dock the wastewater goes through the city purification system before being released into open water. Testing of this water reveals that it is drinkable at this time. However, it is not used for drinking water. Legally, the wastewater can be released at sea, but the FREEDOM STAR does not do this.

Personal Log

The waves did not reach the expectations of 30 knots and the ship did not rock and roll as much as expected. This morning is very gloomy and much cooler due to the cloud cover. The viewing of Port Canaveral in the distance brings a certain element of excitement, as does going under the drawbridge and entering the lock. However, I am sad to reach the conclusion of this wonderful adventure. I have many wonderful memories and pictures to keep forever. I thank NOAA for selecting me and giving me this fantastic opportunity to enhance my life and the lives of my students.

Question of the Day

Answer to yesterday’s question: In 330’ of sea water the pressure is equivalent to 10 atmospheres of pressure from the surface to outer space. The fish have difficulty withstanding the increase in pressure and, quite often, do not survive. Fish have swim bladders that help them keep position in the water. When they are brought to the surface from a deep depth, the pressure decrease causes the bladder to expand. Too much expansion kills the fish. Today’s question: How does it feel to be selected as a NOAA Teacher at Sea and spend six days on a NASA ship in the Atlantic Ocean?

Today’s answer: This has been one of the best experiences of my life and I can hardly wait to tell everyone about this cruise, the importance of exploring the ocean for scientific purposes, and show my pictures.

Interview with Marta Ribera

The ship passes beneath the drawbridge as it returns home to Port Canaveral.

Marta was born in Gainesville, Florida and moved to Barcelona, Spain at the age of 3 ½ years. She received an undergraduate degree with major emphasis in General Biology and a minor in Ecology from the Autonomous University of Barcelona. Following a year of graduate work in GIS, Marta received an internship at the National Marine Fisheries Service in Panama City and has been with NMFS for the past three years. On this cruise, Marta oversees the use of the CTDs (Conductivity, Temperature, Depth) and records all data collected. The larger CTD (valued at $18,000) is used to record conductivity, temperature, depth, salinity, dissolved oxygen, and clarity of water. A smaller CTD (valued at $1,800) is placed on the ROV and records pressure, temperature, and depth of the ocean. At the Panama City Lab, Marta also works with multi-beam mapping, GIS, and is conducting a study on juvenile snapper with Stacey Harter. One of her goals is to complete a Master’s Degree in GIS applied to Fisheries and Marine Biology. “The best thing about my job is that I love the people with whom I work and nothing is ever the same.”

Interview with Mr. Wally Exell

Chief mate and Relief Captain of the M/V FREEDOM STAR

Mr. Exell is the Captain of the FREEDOM STAR for our NOAA cruise. He was born in Bermuda and received his education from the Merchant Marine School in England. Ever since he was young he wanted to go to sea. His love for the sea led him to working with the NASA Missile Retrieving program for the past 24 years. He has been with the FREEDOM STAR for the past 16 years. When at sea, he is on an active duty for 4 hours and then on stand down (on call) for 8 hours. “The best thing about my job is that my work is very unique and interesting and I am honored working with this Program and the great crew.”
