For those scientists who live in Antarctica, however, it's harder. They aren't going back to port every week to stock up on supplies. Instead, they get supplies delivered to them. And since it's so hard to get that much stuff to Antarctica, they have to do it all at once. Research stations in Antarctica will have big supply ships come through every couple of months and drop off thousands and thousands of pounds of food. And since that food has to last them for ages, they usually get stuff in cans.
You'd think that the whole continent would be like a refrigerator, but since the temperature changes so much, there's no way to control whether the food gets freezer burn or melts on a warm day. So the chance to eat "freshies," that is, food that isn't from a box or can, is a real treat for them!
Every morning, the boat had a buffet breakfast with eggs, sausages, bacon, fruit... you name it! For lunch, it was also a buffet, usually with a soup, some meat, and salad. At dinner, we got a set menu that usually had an appetizer like fried mushrooms, a soup, a salad, a main course with things like pork and apples or roasted salmon, plus a dessert.
The food was pretty good, but it was hardly the point of the trip for me. I was so excited to go sightseeing and exploring that I powered through all my meals and left the mess hall as quickly as possible.
A big boat like mine has a full kitchen like any restaurant, with waiters and everything.
