Damian Carrington, an environment editor who boldly ventured to Greenland with scientists, joins interviewer Madeleine Finlay to discuss their groundbreaking expedition. They explore the uncharted abyss beneath the glaciers, investigating how ice and sea interact and the implications for rising sea levels. The conversation reveals the innovative technologies used, like the NERID Underwater submersible, and the urgency of understanding glacial dynamics in the context of climate change. Their findings could reshape our understanding of this critical issue.
The expedition underscored the importance of studying the interface between glaciers and oceans to better predict sea level rise.
Advanced underwater technology, like the NERID submersible, was crucial in capturing detailed data on glacier dynamics and sediment effects.

Expedition to Greenland's Glaciers
A journey to Greenland involved multiple modes of transportation, including planes, a helicopter, and a boat, to reach a research vessel in a remote area known for its stunning yet harsh landscape. The researchers aimed to study the interface where glaciers meet the ocean, as this region holds critical insights into climate change and sea level rise. As the team navigated this challenging environment, they recorded the natural sounds of melting ice and movement of glaciers, capturing the powerful dynamics of this unique ecosystem. Their mission focused on gathering data that could significantly enhance understanding of how ice melting contributes to global sea level rise.
Understanding Glacier Behavior
The scientists on the expedition sought to understand why some glaciers retreat faster than others, a crucial factor in predicting future sea level rise. They discovered that the behavior of these glaciers might be influenced by sedimentation, with layers of sediment acting as potential slowdowns for melting processes. By examining different types of glaciers, they aimed to create more accurate models for predicting their behavior and thus provide valuable information for coastal communities. This research is essential for improving responses to climate change, which poses threats to billions of people living in coastal areas.
Innovative Data Collection Techniques
To gather detailed data near glaciers, the team employed an advanced submersible named NERID Underwater, capable of operating in extreme conditions under the ice. The submersible was unique in its ability to capture high-resolution images and collect sediment samples while maneuvering close to glacier faces. The process of obtaining data was complicated due to high sediment flow and dynamic conditions, but the team successfully captured unprecedented information about the glacial environment. The new data is expected to enhance models of glacier behavior and improve understanding of the implications of ice melt for global sea levels.
Environment editor Damian Carrington tells Madeleine Finlay about his recent trip to Greenland on board a ship with a group of intrepid scientists. They were on a mission to explore the maelstrom beneath Greenland’s glaciers, an area that has never been studied before, and were hoping to find answers to one of the world’s most pressing questions – how quickly will sea levels rise?.
