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... -
(Table 1) Helium concentration in sediments
Two decades ago, Merrihue (1964) reported 3He/4He ratios of >10-4 in ferromagnetic separates from a Pacific deep ocean red clay and concluded that the high ratio is due to... -
(Appendix 1) Crustal helium-4 abundance and flux data for ODP Hole 130-806B
The mass accumulation rates (MARs) of aeolian dust in the ocean basins provide an important record of climate in the continental source regions of atmospheric dust and of the... -

We present a data set of oceanic trace gases collected during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC, PS122) expedition, during which... -
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... -
