Antarctic advice needed

HI! My wife and I are about to realize a dream. We have booked a Linblad trip to the Antarctic Peninsula in late November and we are seeking advice from photographers that have been there. Any advice regarding photo gear and or clothing needed would be greatly appreciated.
We shoot with the following cameras D4s, D3, and D-800 and have an assortment of lenses. We are older but are in good health and don't want to carry unnecessary equipment but want to take best advantage of this photo opportunity.
Some concerns: tripod? hiking poles? most used lenses, other essentials

Best of Light!

Artie has been there many times, I believe he is going there again. I'd PM him.

Artie has his PM function turned off. You should e-mail directly if you want to reach him.
