Measurements of air‐sea gas exchange at high wind speeds in the Southern Ocean: Implications for global parameterizations
velocity is proposed, which is consistent with previou s 3 He/ SF 6 dual tracer result sf rom the coastal and open ocean obtained at lower wind speeds. This suggests that factors controlling air-seaExpand

River runoff, sea ice meltwater, and Pacific water distribution and mean residence times in the Arctic Ocean
Hydrographic and tracer data collected during ARK IV/3 (FS Polarstern in 1987), ARCTIC91 (IB Oden), and AOS94 (CCGS Louis S. St-Laurent) expeditions reveal the evolution of the near-surface waters inExpand

Cooling of Tropical Brazil (5�C) During the Last Glacial Maximum
A 30,000-year paleotemperature record derived from noble gases dissolved in carbon-14-dated ground water indicates that the climate in lowland Brazil (Piaui Province, 7�S, 41.5�W; altitude, 400Expand

Freshwater balance and the sources of deep and bottom waters in the Arctic Ocean inferred from the distribution of H218O
Data from sections across the Eurasian Basin of the Arctic Ocean occupied in 1987 and 1991 are used to derive information on the freshwater balance of the Arctic Ocean and on sources of the deepExpand

Redox control of arsenic mobilization in Bangladesh groundwater
Abstract Detailed hydrochemical measurements, δ34SSO4 and 3H analyses were performed on 37 groundwater samples collected during February 1999, January and March 2000 from 6 locations in eastern andExpand

Paleotemperatures in the Southwestern United States Derived from Noble Gases in Ground Water
A paleotemperature record based on measurements of atmospheric noble gases dissolved in ground water of the Carrizo aquifer (Texas) shows that the annual mean temperature in the southwestern UnitedExpand

Arctic river-runoff: mean residence time on the shelves and in the halocline
The mean residence time of river-runoff on the shelves and in the halocline of the Arctic Ocean is estimated from salinity and tracer data (tritium, 3He and the 18O/16O ratio). These estimates areExpand

Tritiogenic 3He in shallow groundwater
Tritium, helium isotope and neon data from a multi-level sampling well (DFG 7) at Liedern/Bocholt (West Germany) are presented and discussed. The presence of a radiogenic helium component leads toExpand

A paleotemperature record derived from dissolved noble gases in groundwater of the Aquia Aquifer (Maryland, USA)
Low 14C activities in groundwater of the confined part of the Aquia aquifer in southeastern Maryland suggest that most of this water infiltrated at least 30,000 years ago. However, radiocarbonExpand

Helium in deep circulating groundwater in the Great Hungarian Plain: Flow dynamics and crustal and mantle helium fluxes
Observed helium concentrations in deep circulating groundwater of the sedimentary basin of the Great Hungarian Plain (GHP), Hungary, cover a range of three orders of magnitude (≈4 ·10−8 to 4 · 10−5Expand
