Without the help of icebreaking ships, all-terrain vehicles and tough machinery, most Antarctic science could not happen. The French ship L’Astrolabe is a crucial facility for scientists exploring the Earth’s climate, oceans, atmosphere and ecology.
Every year, the ship and its crew, managed by the French Navy for the Institut polaire français Paul-Émile Victor (IPEV) from Hobart, support approximately 50 French and international scientific projects based out of the French stations Dumont d’Urville and Concordia. L’Astrolabe also transports food, supplies, logistics officers and scientists to and from the Australian Antarctic Division’s base on Macquarie Island.
On a series of calm, cool mornings in April 2017, 70 French scientists (from the French space science agency CNES, CNRS IRAP, and the Université Paul Sabatier de Toulouse) launched three enormous balloons into the sky above the heart of Australia.
CNES was using the Alice Springs Balloon Launching Centre (ASBLS) to send three precision scientific instruments up to altitudes of 30–40 kilometres to make observations that are impossible from the ground.
Ocean acidification, caused by increasing amounts of atmospheric carbon dioxide dissolving in the ocean, poses a serious threat to marine ecosystems.
Increasing acidity affects the ability of some planktonic organisms to form shells, and is expected to change the species composition of plankton, with flow-on effects to higher levels of the food web.
Thermometer-based climate records started in 1850, so scientists have gone “back to nature” for sources of long-term climatic information to help them better understand climate change and rising sea levels.
