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... -

To maximize the size of the samples analyzed, aliquots of 2 to 3 g were leached in 10% acetic acid for 6 h to remove CaCO3. This resulted in residues of about 250 mg of... -
(Table 1) Helium isotope ratio of ODP Site 198-1209 sediments
We attempt to constrain the variability of the flux of extraterrestrial 3He in the Paleocene by studying sediments from Shatsky Rise (Ocean Drilling Program, ODP Leg 198) that... -
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,... -

(Table 1) CaCO3 and He concentrations in sediment core TTN13-72
The availability of CaCO3 and 3He content results for core TT 13-72 from 4.3 km depth in the equatorial Pacific (Marcantonio et al., 1996, doi:10.1038/383705a0) allows the... -
