The Ice Drilling Design and Operations (IDDO) group at the University of Wisconsin-Madison designed and built the South Pole Ice Core (SPICE) drilling system, called the Intermediate Depth Drill. Based on a Danish drill called the Hans-Taunsen drill, the Intermediate Depth Drill was purpose-built for coring 1,500 meters of ice. The ice cores collected at this depth (from the South Pole) contain atmospheric gases from the past 40,000 years, the time of transition from the last ice age to the present warm climate.

Photographs of alkaline magmatic intrusions in Greenland. The region was volcanically and tectonically active around 1.2 billion years ago. Although no longer active, it is of major interest to geologists because the subsequent uplift and glacial erosion have cut deep into the rift and exposed the magma chambers that once lay well below the surface. Greenland’s magmas were sourced from a mantle that was enriched and contaminated by ancient crustal materials. Credit: University of St Andrews
