Antarctica is like nowhere else on Earth. Icy and unforgiving and not owned by any one nation. But with threats to polar security and the splintering world order, can Antarctica stay neutral and unclaimed?

In February, CBC's international climate correspondent Susan Ormiston, along with her producer and videographer, joined polar climate scientists and the Canadian Navy for a month-long journey to the Antarctic. It was the first all-Canadian trip to the continent.

With exclusive access, Susan and her team documented stunning vistas, curious penguins and the gritty daily grind of scientific field work as HMCS Margaret Brooke made its way through towering icebergs, beyond the Antarctic Circle to the South Pole.

Some of their footage and reporting was captured in a one-hour special program about the historic Canadian Antarctic expedition.
