There are at least two Antarctic symphonies, by Vaughan Williams and Maxwell Davies, both of which are splendid. The Vaughan Williams is more traditional and perhaps more approachable, while Maxwell Davies had the advantage of actually visiting the place, so you might find it more authentic.
[Added] It seems that the Maxwell Davies isn't available on disc, so that one may not work out!
