I didn't realize the base was so big. I mean, obviously, it's not big, but there's a lot more there than I realized. How many bases are in use down there? Do you know what the average population is at Rothera at any given time?
The UK has two year-round bases - Rothera is the only one with a gravel runway, so it's used as a main port of entry to Antarctica for the planes (from various countries). The other is Halley, which about 1100 miles from Rothera and is the one on the ice shelf that looks like some blue alien building (which is being moved due to cracks in the ice) - Halley has had to close for the last 2 winters though, due to worry over human safety with the cracks in the ice.
There are also several other international bases around the continent:

The ship only comes in during the summer months (November and April - though the first one didn't arrive until Jan 31st when I was there), and the planes and pilots, and most of the staff (including us) only work there between October and March... so from March to October, there is no physical contact with the outside world - no post, no ships, no planes, no food deliveries, just those 20 people.
Here's the oncoming winter team from when I was there (so the team who stayed between March and October 2017 - they do 18 months in total: summer, winter, summer):
