Here's my bonus post. :) Snacks in Antarctica!
At the Australian base, "expeditioners live mostly on frozen and canned food, supplemented to a small degree with hydroponically grown salad vegetables. At the beginning of the season, or following the arrival of a ship, some fresh food becomes available. ... With such a wide variety of frozen and canned food available today, expeditioners enjoy a mixed and interesting diet, very similar to what they would eat back home. The stations are stocked with about 700 different varieties of foods each year." But when going out into the field, even on short trips, researchers have to bring emergency ration packs. These include "freeze dried meat and vegetables, rice, pasta, biscuits, dried fruit, soups, muesli bars, desserts, chocolate, tea and coffee."
Thanks to the Australian Antarctic Division whose website (http://www.aad.gov.au) is totally amazing!
