Circulation of Tritium in the Pacific Ocean
Tritium Pacific Ocean high-latitude Northern Hemisphere waters
2009/2/9
The input of bomb tritium into the high-latitude Northern Hemisphere waters has demonstrated the spread of a tracer in three dimensions in the North Pacific Ocean. Subsurface tritium maxima in middle ...
Simulation of Bomb Tritium Entry into the Atlantic Ocean
Bomb Tritium Entry Atlantic Ocean March mixed-layer depth
2009/2/6
Atlantic tritium distribution is modeled using a three-dimensional advective field predicted by a primitive equation ocean circulation model. The effect of wintertime convection is parameterized by ho...
A Tritium Box Model of the North Atlantic Thermocline
Tritium Box Model North Atlantic Thermocline subtropical gyre
2009/2/5
A box model of 1972 tritium observations on isopycnal surface in the main thermocline of the North Atlantic subtropical gyre is used to estimate the time scales and volume of exchange of the thermocli...
The Penetration of Tritium into the Tropical Pacific
Tritium Tropical Pacific Equatorial Currents
2009/1/7
The persistence of subsurface tritium maxima coincident with the Equatorial Currents is used to show that advection along isopycnals by the mean wind-driven circulation is the dominant process in the ...
Numerical Studies of Tritium and Helium-3 in the Thermocline
Tritium Helium-3 Thermocline
2008/12/27
The effects of circulation and lateral mixing on the distributions of tritium and heliurn-3 in the thermocline are investigated using a two-dimensional numerical model. The gyre circulation was approx...
Ventilation of the Deep Western Boundary Current and Abyssal Western North Atlantic: Estimates from Tritium and 3He Distributions
North Atlantic Deep Water deep western boundary current
2008/12/15
The tritium and excess 3He data from the 1981 TTO/NAS program are used to study the time scales for the ventilation of the deep western basin by recently formed North Atlantic Deep Water (NADW). The l...
Why Is There a Tritium Maximum in the Central Equatorial Pacific Thermocline?
Central Equatorial North Equatorial Countercurrent
2008/10/27
It is suggested that the tritium maximum in the central Pacific is caused by two water pathways across the North Equatorial Countercurrent (NECC), one from the central Pacific and the other from the M...
A Basinwide Estimate of Vertical Mixing in the Upper Pycnocline: Spreading of Bomb Tritium in the North Pacific Ocean
Basinwide Estimate Vertical Mixing Upper Pycnocline Bomb Tritium North Pacific Ocean
2008/7/21
The vertical diffusivity KV in the upper half-kilometer of the North Pacific subtropical pycnocline is estimated from observations of the spreading rate of anthropogenic tritium. The calculation is ba...
