From changes in Arctic mud to the future of the Larsen C ice shelf, come and join Pint of Science for one on the rocks as we explore the rapidly changing landscape of our frozen poles, and the trials and tribulations of conducting research in some of Planet Earth's wildest places.
Larsen C Ice Shelf: What's the Crack?
In July 2017, Antarctica’s Larsen C Ice Shelf hit headlines by releasing one of the biggest icebergs on record. Colossal in dimension (almost three West Yorkshires), iceberg A68 represents over 10% of the Larsen C area – but what do record-breaking stats mean for the future of the remaining Larsen C? After shedding so much ice in one go, does the rest of the shelf risk cracking up? This talk will show how geophysical field surveys are revealing the internal structure of the ice shelf, what they could mean for the future, and some cool photos of Antarctic life! Come along for a cold one!
Getting down and dirty: Unearthing the effects of rapidly disappearing Arctic sea ice
With sea ice shrinking to another near-record breaking low this year, the possibility of a seasonally ice-free Arctic Ocean by 2100 seems increasingly likely. This environmental transformation is fundamentally changing the Arctic ecosystem, affecting everything from bacteria to polar bears, and even us. Allie will talk about the nutrients that support life in the Arctic and show how scientists use mud collected from the bottom of the sea to understand how nutrient availability will change in an ice-free world. Stop by for a story of ice, mud and the adventures of Arctic scientists at sea.
