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 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...
