Erin Pettit has conversations with glaciers. Mainly she listens. As she translates their language shell tell the rest of us what theyre saying about sea level rise climate change and how critical processes like ocean circulation may be transformed.
Pettit came up with the idea of using underwater listening instruments to record the noisy boundary of ice and sea. Acoustic research has already contributed much of what we know about the ocean she observes. But no one had applied the technique to studying glaciers.
Glaciologists love to examine the ice-ocean boundary because its dynamic nature may reveal what triggers glacial changewarmer water the atmosphere above or as yet unknown forces. Its also a very dangerous place. Scientists have long looked for ways to safely make measurements amid disintegrating ice shelves and iceberg-jammed waters. Pettits carefully placed hydrophones in Alaska and the Antarctic Peninsula could be one ingenious way.
