This is a special message for my new Earth Science students, members of the class of 2014 who are participating in 9th Grade Orientation at Lincoln-Sudbury Regional High School today. I am sorry that I cannot be there with you. I am excited to be your teacher this year – you are important to me, and I look forward to getting to know you when I return. You are in the caring and capable hands of Mrs. Iskandar during my absence. Please be respectful of her and thank her for agreeing to cover my classes for the next week in addition to her normal responsibilities in the Science Department.
As you can see, I am a bit too far north to get there on time. I am currently in the Arctic Ocean on board the U.S. Coast Guard Cutter Healy. The ship icon on the map below shows where I was at midnight on 31 August, which was 3 a.m. in Massachusetts. The red lines on the map show different places that we have been during the last month.

We left Dutch Harbor, Alaska (pictured on the right) on Monday 2 August, cruised North through the Bering Sea, and have been in the region of the Arctic known as the Beaufort Sea and the Canada Basin for the last four weeks. I am here participating in an oceanography research expedition as a representative of the NOAA Teacher at Sea program. The research mission is called the Extended Continental Shelf Project. It is an international, multiyear effort between the United States and Canada to map the seafloor and the subsurface in the Arctic Ocean off the coasts of the two countries. Healy (pictured on right) and the Canadian Coast Guard Ship Louis S. St. Laurentare both icebreaker ships designed specifically for scientific expeditions in the polar regions. We made it as far north as 82.5º North and are now moving south again. There is still ice around us now, but not as much as we saw just a few days ago. I have been taking a lot of pictures, and I can’t wait to share them with you. Here are just a few from the last couple of days.

A week from now, on Monday, 6 September, we will leave the Healy by helicopter at Barrow, Alaska, the northernmost town in the United States. I expect to be back at school on Friday, 10 September.

Before then, I hope you will take some time to look through my blog and read about some of the things I have seen and done. Then, I would appreciate it if you would send me a short email at this address: Introduce yourself to me and then either make a comment or ask a question about the Arctic, either based on something you read in my blog or just something you wonder about and would like to know. I will do my best to answer all your questions, and I will give you an extra credit homework grade for your effort.

Enjoy your first week of high school. Don’t get too overwhelmed by the size of the building or the crazy way the class schedule works. You will get used to it in no time. Have fun.

I’m looking forward to hearing from you. I will see you soon.
Miss Singler
