Today I thought it would be helpful to discuss why a ship is being used for the aerosol experiments. As you know, our planet is approx. 70% water which logically indicates that particles would be moving over water even more than land. The atmosphere over water, particularly remote waters, provides ideal conditions for sampling. The slower speed at which the ship moves permits the scientists to conduct testing at a manageable pace as compared to samplings taken from airplanes.

The ship can take the scientists to locations on the planet only accessible by water. It becomes a floating platform for data collection and experimentation.  The ship can also follow the wind patterns across the seas (ie:  tradewinds/westerlies). These winds carry particles from one continent to another.

The testing of air samples on board focuses on many aspects of aerosols. For example, some equipment may focus on how light energy and particles interact in the air as well as in the water, while another type of equipment focuses on size distribution of particles in the atmosphere. Understanding what types of organic and inorganic particles are collected is significant in terms of determining origin and interactive behaviors.

This is just a small sampling of the types of experiments taking place on the ship. The testing and collection of aerosols is a daily activity. At times the scientists must work under difficult and awkward conditions that are directly influenced by weather, seas and swells. They also conduct their testing at all hours of the day. It may look like a “cruise” but it is definitely a “working cruise”. It calls for committed scientists with a sense of adventure and endurance.

QUESTION OF THE DAY: What is the difference between a “sea” and a “swell”?

Talk to you tomorrow. The albatross are still with us!

Today is officially day 3 at sea. We just finished our 8:00 am organization meeting. Each day we post the actual location of the ship. Yesterday we were 26N,161W. Today we will be 34N nd 164 W. Time zone change will occur at around 23:00 hrs. Then we will be 6 hours earlier than the east coast time. We change from zone #10 to zone #11 at 160 W. You can see how just this information alone would be good for an interdisciplinary study with social studies or geography.

We have left the Tradewinds and are now in the Westerlies. Ocean is rougher and
air temp. is much cooler. They expect a period of sun this afternoon and then we could be heading into a rainy front. Last night the rocking of the ship was much more pronounced. I could feel myself rolling around in the bunk. I will try to tape record the sounds at night. They would be perfect for a horror movie. Lots of clanking, groaning, crashing of metal on metal and then water sloshing around. Cool!!!

Today, I had a tour of the bridge. WOW what an awesome sight that is! The technology involved with running this ship is amazing. That will be a place to visit when seas become higher.

The albatross are still following (remember the Rhyme of the Ancient Mariner?)
We had better treat them well.

Today’s testing off the stern was similar to yesterdays. Only today the measurements were not just practice. I learned that the phytoplankton are considered to be “particles” in the sea since they too have influence on the behavior of light in the waters and above the waters. They would definitely be considered to be some of the larger particles. Non the less, they have an impact.

Questions for today: What is a fetch? Why are they different in the Pacific compared to the Atlantic? When sailing, which sea would you prefer to experience and why?

Talk to you tomorrow,

First day at sea was terrific! Blue waters like I have never seen. Almost a Royal Blue. We had company off the stern today. Two young albatross having a great time soaring on the air wake behind us.

Questions of the Day: What is so unusual about the albatross? How long can these birds keep flying? Where do they sleep?

A number of practice runs on scientific equipment were performed today. Weather balloon was released (photo to follow) to measure the temperature, pressure, wind speed, humidity, etc.. Later a CTD was lowered into the waters to measure water temperature and conductivity at various depths. (photo to follow)

Two different satellites pass over the ship twice/day. The SeaWifs and the N16. It would be an interesting assignment for students to investigate these satellites in terms of: How they actually work, Who owns and operates them, and What types of images do they produce?

Other scientific was tested as well today. Tomorrow should be the “real thing” with a number of these devices. I will report on them later.

One final exciting happening! A beautiful Mahi Mahi was reeled in off the stern. Actually – no reel was involved, just a thick rope with a lure on the end. Now that’s “Fishin”!

We are off into the Pacific! Today and tomorrow we are in the trade winds, so the weather is beautiful! Seas are definitely rolling but it is really like an amusement park ride. Manageable! But, shortly we will be in the Westerlies where they say “batten down the hatches!”  Hope I have my sea legs by then.

Lots of activity on board.  Scientists getting their equipment in order. We had safety drills last night – “Man overboard” and “Abandon ship”. I received my protective gear for the abandon ship drill. Looks like an orange “Gumby “suit.  Lots of safety procedures to learn and respond to.  Ships are very dangerous places!

Sleeping was an interesting exercise. The ships anchor is not attached as securely as it might be. Therefore, we hear loud clinks and clanks during the night. The anti-roll tanks slosh water around particularly when the ship is rocking and rolling. Ear plugs were definitely a necessary piece of gear!

I will let you know what today’s experiments involve if there are any.

Talk to you soon

You know how sometimes in our lives we have opportunities presented to us and we hesitate? Then other times we dive right in without a second thought. No fear, no doubt. Who knows for sure what makes us behave differently at different times?

When I was offered the opportunity to go to the famous Marine Biological Laboratories to take a week long teacher workshop paid for by Pfizer, Inc. in August of 1999, there was no doubt or fear, I dove head on! The atmosphere there was awe inspiring to say the least. Fabulous laboratories, serious scientists, inspiring lectures, great lab activities, delicious food and of course great scenery.

Part of the scenery was a research ship, the ALBATROSS, sitting in the harbor. Each morning we would stand on the bank drinking our coffee looking at that ship. My mind began to run away with itself, and it occurred to me that I really wanted to go on that ship, or one like it. When I returned home I began to research the ship on the Internet. The email for the ship’s captain was listed on the website. With a push of a button my request flew into cyberspace. All he could do was say “no.” Months later I received a packet in the mail about the Teacher at Sea Program.

I began researching all the ships in the NOAA fleet and studied their schedules, searching for just the right project. In the meantime, my students were aware of my developing dream. Fairly regularly they would ask if I had heard anything or decided on any particular project. Once in a while I would draw a ship on the board with a stick figure of myself waving good-bye. They were amused… But I was dead serious.

The RON BROWN was one of the ships I had decided upon. New, modern and high tech made sense to me. A note with the ships name was posted on my bulletin board almost a year ago. “Never lose sight of your goal” and “keep it alive every day in some small way” was something I had read that stayed with me and that note was a constant reminder. I have since learned the serious reality of that quote. It really is true. It really works. Learning that is a signal to me that I have just begun. The journey begins in two days!

Think “calm seas and clear skies!”
