Well, well, well.. And I thought last night was something. Rather like an amusement ride on Coney Island! When I went to bed the swells were 14-15 ft., but during the night they increased to 20ft. And the winds increased from 30kts. to 40kts. No wonder I almost fell out of bed! The trick is to use your life jacket as a brace to wedge yourself into your bunk. Tends to give you a false sense of security.

This morning we had a “damage assessment” meeting, taking note of any equipment that became mobile during the night. It seems that some of the portable vans changed location on the deck during the night. There will not be much testing going on today. We are battening down the hatches until the storm passes. This morning, one humorous (or possibly disturbed) scientist was actually reading a book titled Shipwrecks of the Pacific while I, on the other hand, was looking for the book titled The One Minute Mariner. It occurred to me that this experience should be a mandatory freshman course for anyone interested in oceanography.  That would certainly separate the men from the boys (or girls as it were). And probably save some tuition strapped parent a few dollars as well.

Last nights “science night” meeting was very helpful to me It clarified a number of issues regarding the project as a whole. ACE-ASIA is a part of the International Aerosol Experiment that has been ongoing since 1995. One of the goals is to bring to the public a broader understanding of the impact of aerosols on society in general. Not only is the issue of climate change a concern, but also the issue of human health, crop production (particularly of wheat and rice in China) and other economic impact.

Specific goals of this trip are to quantify the interactions between aerosols in the atmosphere and to quantify the physical and chemical processes/characteristics of the various aerosols. The interactions of these particles in the air and at the air-water interface are believed to be of significant impact on multiple earth process systems. Not only can the aerosols create a cooling effect by reflecting light energy, but they also can create a warming effect by absorbing light energy. Another interesting point is that the aerosols can have a cloud nucleating effect. They can actually cause the clouds to become larger for longer periods of time… Or, possibly the opposite effect. The question is : What is the impact of all of these processes as they occur simultaneously? Interesting, isn’t it?

What I find particularly fascinating is the process in which Saharan dust clouds travel all the way to Europe and the Atlantic. What other interesting types of particles could be traveling along with that dust? Something to think about….

Since one of the pieces of testing equipment on board is an OCEC Analyzer (organic carbon/elemental carbon) lets have a question that relates to that instrument.

Questions of the Day: What is the difference between organic carbon and elemental carbon? What might be the sources of each type of carbon?

Oh, by the way. It is actually Thursday out here for me. It’s only Wednesday for you. When will I catch up with that lost day?

I am enjoying your email. Keep them coming!
Bye for now,
Susan

Tonight we are experiencing a bit of a storm. Earlier today the Navy notified the ship that it was to change course and head south. It seems that we were headed for a very nasty storm. At the moment we are experiencing some of the effects of it. 14-15 foot swells and 30-35kt. winds. My goodness, are we rocking and rolling! Anything not tied down is flying around. I think one of the experiment stations on the stern has come loose. A few more green faces running to the bathroom. Thank the Lord I am feeling fine. My husband tells me that if I am fine with this, I need not worry.

I will write another journal update tomorrow. It will be sure to include the details of tonight.

Take care
Bye for now,

This morning was another exciting morning up on the bridge, watching the swells and the albatross. We finally identified these birds as an adult and a young Black-footed Albatross. The swells appear to be smaller when viewing from the bridge. Lower down a few decks the swells appear to be a bit more intimidating. We are rocking and rolling today. It is interesting to see how we adapt to these motions. They don’t seem to be bothering anyone any more.

Today we cross the International Date Line and at midnight we turn our clocks back to 23:00 hrs. Then after an hour it will become Thursday instead of Wednesday.  How bizarre! Does that mean we will be “older” or “younger” or just confused?

Yesterday afternoon we turned the ship around and sailed backwards at 5 kt/hr.  Why, you ask? Because the wind was blowing the smoke stake fumes toward the aerosol testing equipment which would not be a good thing. So, we traveled at a leisurely pace for a number of hours and then decided “enough of that”. We turned around again and picked up speed (13 kt/hr) so that the ship would reach the correct position this morning to be directly under the Terra satellite for exchange of information.

Needless to say, the turning around and increasing of speed was like a very loud alarm clock in the middle of the night!

This evening will be the beginning of “science night” meetings. The teams of researchers will take turns explaining how and why they are conducting their experiments. This will be very helpful for me! Then I will be able to pass that information on to you.

QUESTION OF THE DAY: How many more time zones will we pass through by the time we reach Japan?

Bye for now, I am headed back to the bridge! That is the place to be..

My goodness, I am beginning to need the calendar to see what day it really is! The days are beginning to blend together.

There are some “green faces” today. After fairly gentle seas yesterday, the swells have increased in size and the gray clouds are threatening us with rain.  I am ever so grateful for my calm stomach, so far. The ships physician offers a guide with the following helpful hints to ease the discomfort of sea sickness.

1. Drink lots of water
2. Avoid fried foods
3. Take naps ( this is a particularly good suggestion !)
4. Keep some food in your stomach
5. Don’t work at a computer terminal too long
6. Don’t read too long
7. Get topside and breath in fresh air
8. Focus on the horizon or some object that is stationary

Apparently no one is immune to sea sickness. If the seas become rough enough for long enough we may all become green (like Kermit).

Testing continues daily. I am now becoming more familiar with the testing terminology. At times it is necessary for the ship to stop and hold position for a few hours for tests and other times, like today, the ship continues on course but tries to maintain a steadier position. Today is more difficult to do that.

What makes the RON BROWN such an excellent vessel for scientific experimentation
is the vast array of equipment on board. Here is a sample of that equipment.

a. Multibeam Echo Sounding System
b. Hydrographic/Sub-Bottom Profiler
c. Depth Recorder/Indicator System
d. Acoustic Doppler Current Profiler
e. Doppler Speed Log
f. Acoustic Positioning System
g. Conductivity, Temperature, Depth System (CTD)
h. Global Positioning System (GPS)
i. Scientific Computer System (SCS)

Sounds really impressive, doesn’t it? One of my goals is to understand how each piece of equipment actually works.

The albatross are gone now. Where could they go way out here anyway?

QUESTION OF THE DAY: What actually causes motion sickness? Why are some people more susceptible than others?

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,
Susan

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

I’m in the hotel in Honolulu getting ready to go to the ship (RON BROWN) for my trip.  We went to the ship yesterday and checked it all out, and I saw my room.  It was fun.  The people seem very nice.  Lots of activity.  People loading food, equipment, and other items.  We spent the whole day with the NOAA camera crew, and we did an interview for the local news last night KHNL (News 8/NBC).

I met my roommate.  We talked a couple times on the phone and via e-mail.  She seems just great.  I also spent some time with Dr. Tim Bates and met some other scientists.  Dr. Bates is very nice.  We also had lunch on the ship yesterday, and the food was good.

Well, I guess this is it; I can’t back out now. It looks like it will be great fun.  It’s beautiful in Honolulu.  I look forward to sending you all e-mail and pictures too.

Today, we went to the airport where the C-130 is housed.  The airplane is so awesome and so impressive; it’s overwhelming.  It barely fits in a hanger because it is so big.  We had a great session with Professor Barry Huebert, and he went through the airplane with me and explained all of the different forms of equipment and who designed the equipment, and what it all does. What was really good for me was that everything that Professor Huebert explained to me matched up with what my professor from West Chester gave me about aerosols and the experiments.

It was really exciting to see all of the technicians working on the equipment and getting it connected and hooked up and working on the airplane.  It was a wonderful and awesome experience.  I was also privileged to be able to meet the Department of Commerce Secretary Donald Evans.

Tomorrow we leave for Los Angeles to meet with another scientist; I’ll get a chance to talk to him and interview him and then I’m off to Honolulu.

I’ll write again soon,
Susan
