Zodiac (DNS code for Ice-ocean boundary layer)
From the project summary: Melting of grounded ice mass in the Arctic and Antarctic may play a key role in future global sea level rise and Earth's climate system. The Antarctic Ice Sheet is losing ice at an increasing rate, primarily due to ocean-driven melting beneath ice shelves. The physics...
