Journal Entry

Location: 43.13 N, 89.28 W

If you are reading this journal entry it means I was able to post it using the satellite phone and not an internet connection. This might sound easy to you, but I had to struggle to get the computer and satellite phone to work properly. Why would I go into all this trouble instead of using the internet if the expedition has not started? Because we do not know if we will have internet access at King George Island. Escudero base will be doing some maintenance work on their internet setup during our expedition, so it is not clear yet if it will be available.

The satellite phone works similarly to a cell phone. Your cell phone beams the information to a nearby cell tower, who relays the signal to another tower, and then another tower, until the cell phone you are calling is found. The satellite phone, as it names indicates, beams the information to a passing communications satellite, and not a tower on Earth. The satellite beams back the signal to a relay station that sends the information to a regular phone system. Our sat phone uses satellites that orbit the Earth at a low altitude (1500 Km or 930 miles). One of the challenges is that we need to have a clear line of sight to one of the many communication satellites orbiting the Earth. This means we probably need to be outdoors and away from buildings. Here is a picture of the setup at the high school when I was testing it for the first time at 18F. I managed to send a short test message to Alaska that said "This is a test" and only took me half an hour.

This setup, albeit very different, reminded me of the 1980's movie character E.T. calling home. We will use this phone for an occasional call to home as well, but it will mostly be used for sending the journals to the PolarTREC offices in Fairbanks, Alaska. Someone there will post them on this website using the internet. We need to practice setting up the equipment so we can troubleshoot here, where we have plenty of resources, and not in Antarctica, where resources will be more limited. I also need to condense the journal entries so they are small enough to be sent through the short connection time that the phone has. The images also need to be compress to a very small size (80 kBytes), and be sent one by one. That explains why these images are smaller than the ones from previous postings. I plan on replacing the small images we send from Antarctica with bigger ones once we get back to the internet world. Here I am, sending this text at 12F while my car is at the shop in Madison..

Wonderful to see you and the students working on this so diligently. Your timing, as always, is impeccable. We are in Fairbanks at orientation right now, so I know we will definitely bring your journal into the room tomorrow to share with those needing to learn about sat phone use. I'm so glad for you to be headed out again, love your journals.

Juan,Everything looks good and I'm sure you and the students are getting pretty excited about the expedition! You are the right man for the job. I can't wait to follow along and join in on the learning and the energy you all will generate! Keep up the good work and have a wonderful time. Be safe and have fun!

Hi Juan! So wonderful to see your smiling face and what an awesome expedition you and your students are going on! Wahoo! Very exciting. I'm so appreciative of you translating your journals into Spanish, my ELL students are really enjoying being able to learn about Antarctica in their native language! We started a project which included your student's journals before I headed up here.take care, enjoy the journey and safe travels!

I do nto blame you, Janet, for being concerned about the computer out there in the snow. It did nto get wet and survived better than my phone, which dies with a 70% of charge until I came indoors. Glad I did nto post the one in which it shows actual snow falling :)

Hi Susan, thanks for your comments. I am glad you were able to make it to orientation, that should be a lot of fun. Hoe you will see some auroras! Enjoy the week and say hello to all.

Thank you John,   you are right, we are very excited about this amazing opportunity. We have an amazing team of students from whom I will learn along the journey. I also look forward to learning from the teachers and students from Chile. Their project are very sophisticated. Thanks for the kind words. Hope to see you soon,Juan.

Hi Lisa, thank yo for your support and kind words. And for letting me know that the translation is useful! I sometimes wonder how useful is all the time and energy I put into them, and is wonderful to know that they are actually useful. Interesting to say that it is easier to translate myself; it is hard to translate others as I want o preserve their own writing style while making the text understandable. I am learning a lot already! Thanks, and enjoy Fairbanks.Juan.

When some one searches for his vital thing, therefore he/she wants to be available that in detail, thus that thing is maintained over here.

It's exciting to see this all coming together. I'm so glad the sat phone worked. Zeb and I are a little concerned about seeing our computer in the snow. We look forward to more journals!
Cheers,
Janet
