Science and Technology Log
Yesterday we had a final meeting of “all hands.” At the meeting, we presented Captain Patrae and Dr. Molly with gifts from our schools. Students from Searles designed sea-life posters that had their pictures on it, and students from Cabello signed their class photo to be hung on the ship. At this meeting we thanked all the officers, crew and science party.
In closing our logs, we would like to honor everyone we sailed with by presenting a pictorial display (a display of pictures). Thanks for letting us sail with you, we’ve learned a lot, had great conversations with our students, and most importantly you’ve shared with us and our students the love of the sea!

Science and Technology Log
Today we had a special treat; we were a part of a “Man Over board” drill! A man overboard drill is held once during a three-month period so the crew is prepared in case someone falls off the ship into the ocean. The drill starts with a “dummy” which is made of an old Mustang (survival suit) and is named Oscar. Next, the Captain makes a call to the Bridge (where they run the ship), and three bells are sounded. These three bells are Morse code (a code of lights or bells that spell out words) and they make the letter “O” for Oscar. Everyone responds to a “Man Over Board” to search for the missing person, or in this case the dummy. Once the dummy was located, the ship traveled to the dummy and brought it on board by means of a large hook. At this point, LCDR Rodriguez and Chief Scientist Dr. Molly proceeded to practice CPR (Cardio Pulmonary Resuscitation– to get the heart started and air into the lungs) on the dummy. Finally, an all-clear signal was given and the dummy was then put away for a drill later on in the year. It was very exciting.
Water was collected from the Bermuda Triangle for Ms. Pratt’s fifth grade class. This area is known for strange disappearances. The Bermuda Triangle is located between the island of Bermuda, Miami, Florida and San Juan, Puerto Rico. Many people have tried to explain what happens to the ships, small boats and planes that disappear and the most reasonable explanation is that there are environmental factors (weather, sea conditions) at play or human mistakes.
Interview with Julia O’Hern
Julia O’Hern is a graduate student in biological oceanography at Texas A & M (Agriculture and Military) University. She comes from the Hawkeye State, Iowa. Julia loves being outside and in the water. She has an interest in environmental science, and this led her to the ocean. Her parents always promoted science activities. For instance, Julia recalls her summer, hiking through the prairie, catching bugs and identifying them. Julia had an environmental science course in her high school boarding school that taught her how to be a field scientist. Julia feels lucky that a creek ran by her home and she could collect big ugly tadpoles. From fifth grade through college she played softball, ran track, and she swam. Julia likes chemistry and physics and is working on a degree in biological oceanography but truly loves whales. “Marine biology,” Julia explains, “is different from oceanography,” which studies how some of the physical processes in the ocean (waves, sea floor, and water) affect where the whales live. Marine biology studies the whale itself including its life cycle, its behavior and how it is affected by people.
Ms. Pratt collecting water from the Bermuda Triangle.
“One of the only times I was out of Iowa, my parents took me on trip off of Maine and we saw whales,” said Julia. This inspired her. To top everything off, she shared, “The coolest thing to ever experience is to be in the water when a humpback whale is singing. It doesn’t even matter how far away they are, you feel their music.” Books she suggested reading are Farley Moats’s, Never Cry Wolf and Jack London’s Call for the Wild as well as anything by Jane Goodall. Her advice to students is: “If you want to do oceanography and study marine life you have to get past math and computers, and it won’t always be fun.” But, Julia agrees it’s worth it.
Assignment: In your sea logs, write the procedure for a “Man Over Board” drill. Label each step that happens. For example: #1 – Put “Oscar” into the ocean.

This has been a very exciting trip! I’ve been stretched beyond my wildest dreams. The correspondence with my students has been meaningful and very educational. Working with the scientists, officers, crew and my fellow teacher has taught me lessons that I’ll never forget! Thanks to all of you for this unforgettable experience.

Thanks to Captain Gary Petrae for welcoming us onboard and sharing so freely resources to help kids understand life at sea. Thanks, too, to Dr. Molly for extending this experience to us through NOAA. Thanks to my principal, Debbi Knoth, and the New Haven Unified School District Superintendent, Dr. Pat Jaurequi, for enabling this trip and to Kim Pratt for inviting me along. Thanks to the crew! Thanks to Mrs. Riach for substituting for me. There are so many interesting and exciting happenings on board. Juliet was a hit and remains with Lt. Commander Priscilla Rodriguez. As Professor Jochem Marotzke shared, life at sea sensitizes you to put yourself in another’s shoes, simply because the job isn’t done when my own shift is over. I had the pleasure of getting quotes from many people here. Robert Bayliss, onboard from the THOMAS JEFFERSON for this cruise, advised anyone interested in life at sea to “Be prepared to spend long times away from home.” Being one of Carlos’ boys with Rigo, Dallas and Mick was a “bonus.” At an all-hands meeting this afternoon we shared our gifts for the crew and NOAA scientists.
Afterwards those who wished got their picture taken in groups. Dr. Molly created a centralized computer space for sharing pictures. I have some CD’s to work with, thanks to Dr. Shari and LCDR Rodriguez. Those kinds of sensibilities make life pleasant. I understand my Uncle Sam better from this cruise. I cannot leave without a special hello to my 14-year-old daughter, Alexandria Jo. When we return, there will be extension activities, such as lesson plans, presentations to prepare and publicity pieces. My enriched enthusiasm and understanding of ocean science will be shared with every student. I got autographs from world-class oceanographers, modern-day explorers, and stand in awe at the collaborative efforts being made to better understand the ocean and its relationship to climate. The current issue of Mother Jones is devoted to the state of the seas. Gratitude was my beginning attitude and remains as I prepare to return to land. What makes a fine sailor also remains: someone who knows their job and gets it done, is dependable, a friendly person to be around, and one who you can trust to watch your back. This applies as a major lesson to those in all walks of life.

Mooring team at work
Science and Technology Log
Besides deploying (launching) buoys, and doing CTD casts, the RON BROWN also has a group of scientists from the United Kingdom (which consists of the countries England, Scotland, Wales, and Northern Ireland) and a scientist from Germany who are putting moorings in the ocean. Moorings are instruments that are sent to the bottom of the ocean and are held there with weights. They can weight up to 3000 pounds!
Also attached to the moorings are floats so that when the scientists decide to get the instruments, they send a signal to the mooring to detach from the weight and then it can float to the surface. After that, the scientists can easily locate the floats in the ocean and then pick the instrument up. The moorings send information to the scientists about the velocity (or speed) of the deep-water currents. They also measure temperature, salinity, pressure and tidal heights. Each mooring costs about $200,000 each!
On the RON BROWN, three large moorings were recovered (picked up) and four more were deployed (put into the ocean). This team has deployed moorings all across the Atlantic Ocean— from west of Morocco, near the Sahara desert region, to east of the coast of Florida (where we are now.)
LT Liz Jones
Interview with LT Liz Jones, Field Operations Officer
LT Liz Jones defined herself as Field Operations Officer, or FOO, as “a coordinator of scientific operations between the science party and the ship’s crew to ensure the mission is carried out and the scientific objectives are met.” While all NOAA Corps Officers have either science or engineering backgrounds, she also had prior seagoing experience before joining the NOAA Corps in 1999. Liz graduated from the Massachusetts Maritime Academy in 1996, majoring in Marine Safety and Environmental Protection. Maritime academies provide classrooms at sea aboard their training ships.
An interactive program called the “Voyage of the MIMI” sparked her interest in the 5th grade. It sounded similar to the current “Jason Project,” where a scientific team videotapes and teleconferences their work from interesting places in the ocean. Liz explained to a high school guidance counselor, “I love the ocean; I want to do some kind of work with the ocean.” Fifteen years later, she is doing just that!
NOAA Corps officers attend three months of Basic Officer Training at the US Merchant Marine Academy in Kings Point, New York. From there, they are sent to sea aboard one of NOAA’s research vessels. A typical career has one rotating two years at sea and three years on land. “I really like the idea of reinventing myself every few years,” Liz explained. The RONALD H BROWN is her second sea assignment. Liz worked at NOAA’s headquarters for her first land assignment She spent one year there as an aide to Rear Admiral Evelyn J. Fields, who was the first African American female to head the NOAA Corps.
As the FOO, Liz is always planning ahead. She stays very busy working on the plan of the day for tomorrow or the logistics for the next four cruises. The most challenging projects to coordinate are the ones where new technologies will be used for the first time. She is thankful to the crew that can make just about anything happen. In her spare time, Liz works out, reads a good book or just relaxes. For interested students, The California Maritime Academy in Vallejo has the Training Ship GOLDEN BEAR, which one day could be your very own classroom at sea.
Assignment: Using a world map, locate Morocco, the Sahara Desert and the east coast of Florida. Draw moorings straight across the ocean to connect these areas.

We finally finished our CTD casts! The last job I learned was how to be “Sample Cop”, which means I wrote down information about each water sample that was taken. When scientists take samples, they need to clean each bottle three times before they fill it with the sample. This is so the sample is pure and not contaminated (dirty) from the previous sample. We use a lot of seawater for this purpose. Thanks for all the e-mails!

I checked out the drifting buoy-tracking site and found our buoy! I have been busy responding to your emails and writing logs. The scientists and crew have been very helpful in helping me be accurate and sensitive in the presentation of the work being done out here. I salute my nephew, in the Navy now. We are getting excited about coming into port in a couple more days.

SHIP VOCABULARY
The meaning of common ship terms may help land “lubbers,” (people who love life off the sea), get around this home on the seas. First, let’s cover directions on a ship. The front is called the BOW and the back end is called the STERN. The very back deck over the propellers is the FANTAIL. Facing the bow, the right side is the STARBOARD SIDE and the left side is the PORT SIDE. The KEEL is under the middle of the boat. The WATERLINE is where the water meets the HULL on the outside of the ship. The picture today is of the interior, or inside of the ship. Use the picture diagram to practice your knowledge of shipboard terms.
A cross sectional view of the RONALD H. BROWN.
The floor of the ship is called the DECK. Stairs to the eight different levels are called LADDERS. The ceiling is called the OVERHEAD and the hallway is called the PASSAGEWAY. When seas are choppy, you hang onto RAILINGS along the passageway and ladders. Railings can keep you from falling. There is a safety phrase aboard that goes, “One hand for you and one hand for the ship.” That means it’s safer to always touch some part of the ship.
Let’s go down where food and supplies are STOWED or put away before being brought up to cook and eat. In the HOLD AND TANK TOP, two decks below the MAIN DECK you find the ship’s STORES, or storage area. There are dry stores, a chill box, a freeze box, a room for cleaning supplies, and another for ship’s supplies, including shelves of flags. That’s five different rooms for food or supplies on this bottom floor, the HOLD. The temperature in the CHILL BOX keeps fruits and vegetables just above freezing, but the FREEZE BOX feels like being turned into instant ice. Those two lockers have safety latches so you can’t get locked inside. Together they measure about 11 feet wide by 12 feet long by 8 feet high, the size of a medium size moving van.
The DRY STORES keep all the extra cereal, tea and dry foods that do not need to be chilled. It is bigger than the freezer locker, about 110 square feet, the size of a small garden shed. It has over 60 shelves, each 2 feet by 4 feet by 2 feet, the size of a garment or hanging clothes type-moving box. Michael Moats, the General Vessel Assistant, pointed out the SOPROLE, a milk product substitute that doesn’t need chilling for a long time. A phone and an elevator are handy outside the supply rooms. The kitchen areas, “the Galley,” and dining room, “the Mess Deck,” are two ladders up, so the elevator and phone make checking on and moving supplies easier. There is also a HEAD, or toilet, on the MESS DECK. The chief steward, Richard Whitehead, mentioned that in the GALLEY the safety bars on the ship’s stoves are called SEA RAILS. A great reference for these and many other ship terms and the flag alphabet is http://www.schoonerman.com/sailingterms/. Time for more ship term practice!
The RONALD H. BROWN is 274 feet long and sails worldwide supporting our scientific understanding of the world’s oceans and climate. The ship was commissioned, at a big birthday-like celebration, on July 19, 1997, in honor of the late Secretary of Commerce, Ronald H. Brown. To commission a ship is to put it into service at sea. The ship carries six NOAA Corps officers, 20 crewmembers, and a maximum of 33 scientists. The ship has two monster motors that give power to the ship. Each one has the power of 3,000 horses pulling a load, or 3,000 hp. Top speed is 15 knots or fifteen nautical miles per hour. That’s a little faster than a car going 17 miles per hour, mph. The ship makes 5,000 gallons of drinkable water a day just like the rain purifies water, by evaporation and condensation. We use about 4,000 gallons a day here. Since we can only make water thirteen miles away from shore we need to not waste our water supply.
Interview with Commander Stacy Birk, Executive Officer
Commander Stacy Birk said, “It’s a tough life at sea,” so she really tries to make life on the RONALD H. BROWN valuable and meaningful for all hands. Stacy is the Executive Officer, XO. As the captain’s back up, the XO is boss in the captain’s absence. She manages people, deals with people’s salaries and serves as safety officer while the ship sails from Charleston, SC, for about ten months of the year. In elementary school Stacy enjoyed the books Island of the Blue Dolphins and I, Nathaniel Bowditch. This California surfer girl completed college and joined the Coast Guard Reserves. She actually sailed around the Channel Islands.
As a personnel manager, Stacy hires people and evaluates them, like a teacher gives grades. As a safety officer, the XO helps people follow the rules, such as not wearing open toe shoes or not leaving kitchen cups around the ship or showing up at the wrong place for drills. You might compare this to a parent making sure rules are followed. She does everything possible to be fair with people. Stacy’s science background and sailing experience help her make accurate observations. Her uniformed service as a NOAA Corps Officer and her rank as XO fit with her respect of the sea from childhood. Not everyone has such a clear direction from youth. She just celebrated her 19th wedding anniversary and suggested to students, “Visit ships in port in San Francisco, explore the TECH museums or practice flag signals,” to grow in ocean knowledge.
XO, Stacy Birk, during the Port Authority passport-clearing trip at Marsh Harbor, Abaco Island, Bahamas
Assignment and question of the day: Use as many of the ship terms in place of the land names. Example: Instead of saying, “I’m walking down the hall,” say “I’m walking down the passageway.” BONUS: Check out that website to learn more ship terms. What is the perimeter of the CHILL BOX and FREEZE BOX together? Hint: Check the length and width of both boxes.

After a great night’s sleep I learned at breakfast that a small shark was sighted during the night as the CTD was at the surface. I also found out about an awesome website, http://www.ngsednet.org/oceans, that has pictures taken by students from my previous expedition to the Channel Islands with National Geographic. You will see more critters on that site, for those interested. In addition, over 7,000 living organisms will be under investigation on the RONALD H. BROWN’s next cruise. I took a tour of engineering today, thanks to Chief Engineer Frank Dunlap. The engineering department powers and maintains all systems on the ship; something like the Corps Yard does for our District. Juliet, the flat person, took some pictures with two of our Southampton college graduates and with a few of the people on Stuart Cunningham’s Mooring Team. Keep up your journal entries and emails.

Hi all. Last night I saw two Mahi Mahi fish, which they also call dolphins or dolphinfish. They were swimming along side of the ship and at first I thought they were sharks! They certainly are beautiful. Yesterday the scientists from the United Kingdom worked on moorings all day so I got some time off. Today we’re busy again doing CTD casts and my job lately has been “cast cop”, which means I log all the data. The weather continues to be nice, although today we went through a squall (which is a storm) and now it’s overcast outside. Also today we received a distress call from a Catamaran that was taking on water, so we proceeded to go to help, but the Coast Guard was on their way and they also called a tow service from a nearby island to help them. It sure added some excitement into our day! With less than a week to go, things have certainly been busy!

Preparing the sounder
Science and Technology Log: The Echo Sounder
For the past few days, we’ve been transiting back and forth picking up (recovering) and launching (deploying) a special kind of buoy called an Inverted Echo Sounder (IES). This buoy is attached to a weight and sinks to the bottom of the ocean. There it sends out a sound pulse to the surface and measures the travel time of that pulse to hit the surface and return to the unit on the bottom of the ocean. Using the travel time of the sound, scientists use it with a historical profile of the water to estimate temperature and salinity of the water. They obtain the historical profile by doing repeated CTD casts and especially the cast before deploying the IES. Sound speed is proportional to salinity/density and scientists use the density and temperature estimations to identify water mass and current movement. Remember, these currents are moving all over the world! The buoy we deployed also had a current sensor as well as a pressure and temperature sensor. When scientists are ready to get the information from the buoy, they travel to the site of the buoy, and park the ship right on top of it, and the buoy sends the information to them.
The buoy at night.
The buoys stay down in the bottom of the ocean sometimes as long as 6 to 7 years but usually they’re picked up after 5 years. They cost between $25,000 and $45,000 each! When scientists are ready to pick up the buoy, they send a signal that tells the buoy to detach from the weight holding it down and then it floats to the surface attached to a large yellow float. At night, it sends a strobe light flashing across the water so it can be easily found. Also in the past week, all the Styrofoam cups that have been decorated by students at Cabello, Searles Elementary, Key Biscayne Community School, and members of the crew of the RON BROWN were lowered into the ocean at about 5000 meters, or a little more than 3 miles below sea level. The effect of pressure can be as great as 70,500 pounds of pressure! This rids the cups of all the air and shrinks them to 75% of their original size. It’s sort of like when you dive into a swimming pool, and while going down you feel your ears get tight— that is the effect of pressure.
The buoy deployed
Finally, although we’ve been out to sea for over two weeks, we’ve seen very little wildlife. We’ve seen pilot whales, two or three squid, flying fish and some little fish called Ballyhoo that dance on top of the water with a long snout. They look like mini swordfish. The reason we haven’t seen much wildlife is that there is very little life in the middle of the ocean. In fact, if you look at the middle of the ocean from space, it almost looks purple because there is no phytoplankton, (green plant material that is the base of the food chain). You’ll find life near the coasts or in the North Atlantic because all animals need nutrients to live and you need currents or up welling to move the nutrients around to feed the phytoplankton (plants) which feed the zooplankton (little animals), which feed the fish, which feed the dolphins, which feed the sharks! This is an example of the food chain.
The cups before pressure…
Interview with Chris Churylo – Chief Electronics Technician
An important person on any cruise is the Chief Electronics Technician or Chief ET as they are called. Their main job is to make sure that all the electronics are working – that means sonar, networks, navigation, radio and all the things that keep the ship going to where it needs to go, and people talking to whom they need to talk. On board the RON BROWN, the Chief ET is Chris Churylo. Chris is multi-talented—not only is he a Chief ET, he’s also a Licensed Practical Nurse, an Emergency Medical Technician, a truck driver, a fireman, a pilot, has a real estate license and is a Notary. Chris likes working on the RON BROWN because he works two months on and gets two months off. While he’s at sea and not working, he likes to play chess, learn guitar and work out in the gym. During his off-time he likes to fly his plane, a Cessna 150, explore local places and hang out with his girlfriend of 18 years. Chris, who grew up in Philadelphia now calls a farm in West Virginia his home. During his career he has traveled all over the world, notably to the South Pole and Barrow Alaska during his 20 years of government service. Chris’s attitude on board the RON BROWN is contagious. He is a happy spirit, energetic and genuinely likes what he does.
Assignment: In your logs, illustrate the effect of pressure. Step one – Draw your decorated Styrofoam cup at the surface. Step two – draw it on the CTD in a bag ready to go to the bottom of the ocean. Step three – draw it now 2/3 smaller than when it started.
…and the cups after pressure!
Personal Log – Kimberly Pratt
Yesterday was a quiet day. We headed back to Marsh Harbor, Bahamas so the science staff had most of the day off with CTD casts in the evening. I got to do some reading about Great White Sharks off the Farallones Islands – outside of San Francisco Bay. One of the main researchers in the book is Peter Pyle, who I sailed with last year on the MCARTHUR II. I’ve really met some great people being a Teacher at Sea. This trip feels like it is winding down with less than a week to go. The weather is still beautiful. Sorry to hear about all the rain and hail back home. Keep writing I love hearing from you all.
Personal Log – Vince Rosato
Sad news came on three fronts today. First, a crewmember heard by ship’s phone of a tragedy in the family and had to be brought to shore to catch a plane back home. If you noticed the ship tracker had us going back and forth from Abaco Island, one of those trips was to bring a crewmate ashore. Second, I heard from my home that a neighbor friend had a stroke and is under observation in the hospital. And third, from my school, a teacher friend is taking the rest of the year off for health reasons. Those things drained my energy. Work doesn’t stop whether we are happy or sad, so I continued becoming proficient at salinity analysis. If counting time, however, I spent most of the day replying to your wonderful emails and working on logs. I got to call out on the radio set the depths to the winch driver, and fire the CTD bottles on the late night cast. That boosted my morale with Dallas, the author, and Mick, the father of Dr. Beal. We have formed a bond with Carlos, our CTD team leader, through our tradition of after-shift snack time in the galley.
