  abstract = {{T}his study is part of the {TOPOGULF} program, in which tracer measurements were closely associated with the hydrological data. {T}he sampled area was located near the {A}zores {I}slands on the both sides of the mid-{A}tlantic ridge. {T}he tritium content of the surface waters reveals a strong front along the {A}zores current. {T}he 3{H}e distributions are used to identify some areas where ventilation processes are active. {A}t depth, the spatial distribution of tritium is studied along isopycnals. {I}n the thermohaline it is essentially the anticyclonic gyre which is responsible for the northeast-southwest gradient in tritium concentrations. {T}he respective influence of the {L}abrador sea water and the {M}editerranean water seems to be ain end member responsible for a decrease of the tritium contents in the north and for ain increase in the south, by mixing. {A} quantitative approach using a mixing model is used to check the validity of the 3{H}e-3{H} "age". {T}he model leads to two extreme values of the time scales for the middepth circulation in the studied area.},
