As I’ve said before I will have limited bandwidth from the boat. I’d like to send not only text but images of the boat, icebergs, Antarctic wildlife, and anything else worth photographing, so I’ve been experimenting with ways of getting images off the ship. Based on the results below, I think I’ll stick to text descriptions rather than text graphics, and perhaps a very low quality (but decently sized) image every once in a while.
Here is a an image of the boat. This image is 77K, which would use 3 days of bandwidth quota to transmit:

The Nathaniel B. Palmer. Image courtesy of NSF. Image size is 77kb
If I shrink the image to 25k, or one day of bandwidth, it is this size

Nathaniel B. Palmer. Same image as above but resized so that it is 25 kilobytes in size, or 1 days bandwidth quota from the ship.
Or I can reduce quality rather that size, in which case it looks like this. The only real difference appears in the now-blurry name of the boat:

Nathaniel B. Palmer. Same image as above but quality reduced so that it is 25 kilobytes, or 1 days of bandwidth quota.
However, if I convert it to ASCII art, it looks like this, and takes up a mere 1.6k. I could transmit 15 of these a day before I reach my quota.

Here is an image I took last time I was in Antarctica, and the ASCII art version too. Image size is about 20k (a day of bandwidth). Text size is less than 2k (I can send around 15 per day):
