Hi Bill, Have enjoyed following your posts, a great opportunity for your students and apparently the other classrooms that are following along as well. I like the topic question you left for your last post, and am wondering if you already planned another on time zones (same relationship). I think the concept of time relative to global position has some goodd teaching points as well. Shipboard time, how keeping a uniform time could cause the approaching sunrise/sets to fall at 'odd' times of day, and on a kind of related note, how length of days change in the Arctic as compared to say Colorado, now that we have passed the Autumnal Equinox and days are getting shorter. I have two specific questions to your trip though, and appologise if I missed the first one on an early post. How was shipboard time determined for the Healy? Is it set to Dutch Harbor, Coast Guard HQ, or some other standard? Also, did the Healy and Louis 'syncronize their watches' so to speak, or did you have to switch to a different tz for your visit?
All the best for the rest of your trip, congrats on the lifers. DaveABirding
