To obtain noble gas samples from the water column below an ice shelf, we have constructed a new gas-tight in-situ water sampler to prevent the water samples from the sub-glacial cavity from gas-fractionation and degassing due to freezing and expansion. The novel instrument contains a degreased soft...
