An autumn voyage to the heart of an Antarctic polynya has rewarded expeditioners on a US icebreaker, including IMAS researcher Dr Guy Williams, with a glimpse of a rarely seen type of sea ice.

The sighting of “Dragon-skin” ice (see photos below) was an early highlight of an ongoing voyage to the Ross Sea by the Nathan B Palmer that began in early April, well after most Antarctic expeditioners have departed for warmer climes.
