Let The Sun Shine!
Of course, when winter leaves, Antarctica is in for months of sunshine. Seeing as the sun now stays above the horizon before the summer equinox, rays of light always beat down on the icy surface.
This means that scientists return to continue their work, and the population jumps from around one thousand to four thousand people. Therefore it is also the perfect time for tourists to see the wonders this beautiful land has to offer, and everybody tries to get as much as possible done before the cold hands of winter make their way around again.
