Excess3He in the Atlantic Ocean
TLDR
3/He4He measurements at two stations in the Atlantic have shown that the deep water (> 2 km) contains far less excess 3/He than the Pacific Ocean as mentioned in this paper.About:

The sulphur isotopic composition of ocean water sulphate
TL;DR: In this paper, the sulphur isotopic composition of ocean water sulphate was determined using the SF 6 method for samples from various depths of the Geosecs Stations II and 3 and for a single Pacific Ocean surface sample.

TERRESTRIAL INERT GASES: Isotope Tracer Studies and Clues to Primordial Components in the Mantle
TL;DR: Ozima et al. as mentioned in this paper focused on helium isotope variations in terrestrial systems, with occasional excursions into the discussions of heavier rare-gas isotopes, such as 3He and 129Xe.

A Major Helium-3 Source at 15°S on the East Pacific Rise
John E. Lupton,Harmon Craig +1 more
TL;DR: An extensive plume of water enriched with helium-3 has been discovered in the deep Pacific Ocean at latitude 15°S on the East Pacific Rise as mentioned in this paper, indicating a strong injection of mantle or primordial helium at the spreading center axis through local hydrothermal systems.
Journal ArticleDOI
Excess 3He in deep water on the East Pacific Rise
TL;DR: In this article, the authors show that water on the crest and flanks of the East Pacific Rise has the highest enrichment in 3He so far observed in the oceans; the 3He/4He ratio anomaly relative to atmospheric helium is + 32% at the mid-depth maximum in the profiles.

Excess 3He in the sea: Evidence for terrestrial primodal helium
TL;DR: In this paper, the authors found a large enrichment of 3He in deep Pacific water, relative to the atmospheric 3He/4He ratio, and concluded that the excess 3He is due to leakage into ocean water of a remnant of the earth's primodal 3He.

Continental water balance, ground water inventory and storage times, surface ocean mixing rates and world-wide water circulation patterns from cosmic-ray and bomb tritium☆
Friedrich Begemann,W.F. Libby +1 more
TL;DR: The tritium produced during the Castle operation in the spring of 1954 has been used to study the circulatory rates for waters in the northern hemisphere, particularly in the Mississippi Valley.

Dissolved gas saturation anomalies and excess helium in the ocean
Harmon Craig,Ray F. Weiss +1 more
TL;DR: In addition to T and P, a third parameter is also required for the study of saturation anomalies as mentioned in this paper, i.e., the magnitude of the injected air fraction, which accounts for about 60% of the excess He in Atlantic Deep Water and about 80% of He in the Pacific.

Helium isotope effect in solution in water and seawater.
TL;DR: The measured isotope effect is in agreement with the ratio of helium-3 to helium-4 in surface ocean water reported by Clarke, Beg, and Craig.

Trace element calibrations and profiles at the Geosecs Test Station in the northeast Pacific Ocean
TL;DR: In this paper, four laboratories collaborated on the trace element analysis of sea water samples obtained on the 1969 Geosecs test cruise in the northeast Pacific Ocean, and the elements determined were Sr, Cs, Rb, Co, Ni, Sc, Cu, Sb, Zn, Fe, and U. The general agreement was good.
