Humboldt

General Information

A series of 10.2 cm diameter, ~20 m deep firn cores drilled in 1995 as a part of PARCA. There is only a small section remaining from each core. There was also a 10.2 cm diameter, 146 m long ice core drilled in 1995 for PARCA called Humboldt BII (HumB2), but that core has been consumed entirely.
