Watching the weather in the far southern seas

A group of young New Zealanders and two meteorologists travel to South Georgia Island in the southern Atlantic Ocean to collect weather observations - continuing the scientific legacy of early Antarctic explorers like Shackleton.

Clarification: In this episode there is a discussion about comparing notes about icebergs taken by Shackleton's team aboard the Aurora to that of the current expedition. What this fails to clarify is that the Aurora expedition travelled through the Ross Sea, not the Weddell sea, where ice activity is notably different.

It's home to one of Earth's most spectacular gatherings of wildlife, with millions of penguins, seabirds and seals crowding the shores.

South Georgia, in the far reaches of the Southern Atlantic, is a wild and isolated island. It's also the final resting place of famed Antarctic explorer Ernest Shackleton.

To commemorate the 100th anniversary of Shackleton's last journey, 22 young New Zealanders travelled with the Antarctic Heritage Trust's 9th Inspiring Explorers Expedition to South Georgia.

In the wake of Shackleton

One hundred years ago, Shackleton's untimely death at the age of 47 marked the end of the 'heroic age' of Antarctic exploration. The period left us inspiring stories of courage and survival - as well as an enduring scientific legacy, which continues to be built upon today.

As part of their expedition to South Georgia, the young New Zealanders continued Antarctic explorers' tradition of meticulous data collection, by recording rare weather observations from this remote and seldom-visited destination.

Accompanied by Kelly Davenport and Peter Fisher, two meteorologists from MetService, the Inspiring Explorers science team conducted regular and comprehensive weather reports using the same equipment, terminology and methods that would have been used in Shackleton's time. But they also brought some state-of-the art weather equipment, which can collect more data than a heroic-era meteorologist could ever have dreamed of.

Lots of data is important for weather and climate science today. Data feeds into global weather models - complex simulations of the planet's atmosphere that assist the near-term prediction of weather patterns worldwide. Data collected from remote locations such as South Georgia is particularly impactful, as it helps us fill in the blanks in the map of Earth's weather.
