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,
