A new helium isotope recored of the Paleocene-Eocene Thermal Maximum from ODP...
The Paleocene-Eocene Thermal Maximum (PETM; around 56 Ma ago) is arguably the most intensively studied event of rapid greenhouse warming of the geological past. The duration and... -

(Table 1) Helium and Thorium 230 excess concentrations in sediment cores B18 ...
At four sites in the central equatorial Pacific Ocean the flux of extraterrestrial 3He, determined using the excess 230Th profiling method, is 8 * 10-13 cm3 STP/cm**2/ka. This... -
(Table 1) Helium isotope ratios of sediment core TT013_114
We present a helium isotope record for core TT013-114PC from the central equatorial Pacific (140°W, 4°N, 4432 m water depth) spanning a period of 1 million years. We focus on... -
(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... -
(Table 1) Helium concentration and flux in DSDP Hole 94-607 samples
Most of the helium-3 in oceanic sediments conies from interplanetary dust particles (IDPs), and can therefore be used to infer the accretion rate of dust to the Earth through... -
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... -

(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... -
STEIN - Stochastic erosion in-situ cosmogenic nuclide model
The stochastic erosion in-situ cosmogenic nuclide model is a 1D numerical model that simulates the evolution of the concentrations of in situ-produced Be-10, C-14, and He-3...
