Laura’s work looks at what the impact the melt water is having on the carbon cycle in the southern ocean.

“This isn’t just water like we drink. It’s full of nutrients and chemicals, as well as tiny animals like phytoplankton frozen inside,” Laura explains.

As it melts, the iceberg releases these into the water, changing the chemistry of the ocean.

That could store more carbon deep in the ocean and would lock away some of the planet’s carbon dioxide emissions that contribute to climate change.

For now scientists are hoping the iceberg will manage to stay away from the island.

On board the South Georgia government vessel Pharos, sea captain Simon Wallace said: “I would be extraordinarily happy if it just completely missed us.”
