Helium isotope record, CaCO3 concentration and accumulation rate of ODP Site ...
The cause of the 100 kyr glacial–interglacial cycles during the past 800 kyr is one of the fundamental puzzles in paleoclimatology. The widely accepted Milankovitch theory,... -

Filchner Ice Shelf cavity noble gas (helium and neon) measurements
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... -
