As the first South African female reporter to oversummer in Antarctica, I work at the leading edge of covering the issues shaping Far South — and North.

Spanning two decades, my polar reporting has appeared in multiple international publications, including PBS, Daily Maverick’s Our Burning Planet, the American Polar Society’s Polar Times, the Lonely Planet Guide to Antarctica, the Sunday Times and more.

My field assignments have helped to animate life at both poles. This work includes:

  • In 2022, my polar investigative series has shown that Russia is scouring Antarctica for fossil fuels despite a 1998 mining ban. Published by PBS and Daily Maverick.
  • No more Mr Ice Guy – China accused of striking down penguin protections.
  • The moment in January 2021 when Russian LNG vessels crossed paths on the Arctic’s Northern Sea Route for the first time in winter without icebreakers.
  • I have spent three months at South Africa’s Antarctic station and visited Norway’s Troll station in the Antarctic hinterland; reported on extremophiles from polar mountain tops; joined defence force personnel on a 400km cargo haul; and sailed the Southern Ocean to cover news/science events.

In the words of polar law expert Donald Rothwell, ‘The issues playing out in front of us in the Arctic must — subject to challenges like available markets — come home to roost in the Southern Ocean.’

Whether on Earth or in the outer realms, the human story is deeply embedded in the poles, as my reporting on global change, the climate crisis, the natural sciences and space sciences helps to show. Browse my latest features for more.

Battleground Antarctica II: Despite mining ban, Russia scours Antarctica for massive fossil fuel deposits

The Kremlin’s mineral explorer says it has found a stunning 500 billion barrels of oil and gas below the Southern Ocean’s climate-threatened waters. Tapping these mooted reserves would not only hamper global efforts to fight the climate crisis. Known for flouting major agreements, a defiant Russia in the Antarctic could destroy the decades-long protected status of Earth’s last unmined frontier. Read the full story

As Antarctic Treaty nations release the Paris Declaration, a new climate manifesto, Daily Maverick can reveal this international investigation: Russia has combed the fragile Southern Ocean for oil and gas on a staggering scale after Antarctica’s mining ban formally entered into force more than two decades ago.
