In one of the first instances of large scale production of food in Antarctica, scientists at the US McMurdo research stations greenhouse, grew lettuce, mint and tomatoes.

The vegetables and herbs were grown under soil-less hydroponic conditions to avoid contaminating the environment with external microbes.

The development was an important step towards improving the nutritional intake of researchers on the continent.

A Chinese scientist, on a research expedition to Antarctica harvested vegetables that were grown in soil-less artificially controlled environment at the Zhongshan research station.

This was the first time lettuce, cucumber and tomatoes have been grown at the Chinese base in Antarctica.

Before the harvest, members of the expedition team had to rely on cargo vessels to ferry meat and canned food products.
