Recent current measurements are incorporated into new heat and mass budgets for the Arctic Ocean. These budgets demonstrate the overwhelming importance of advection by the West Spitsbergen Current, which in 1971-1972 transported 16.3 X 109 kcal cm -2 s -• into the Arctic Ocean. Partially on the basis of the heat budget, we suggest that there is a large heat loss to the atmosphere in the southwestern Eurasian basin, in excess of 20 kcal cm -2 yr -•. Annual mean transport in the West Spitsbergen Current could easily vary by 35% and might constitute a significant perturbation on the Arctic heat budget. The mass budgets point toward the general ineffectiveness of the Arctic Ocean in transforming subsurface water masses, and they also indicate a large shear between the ice and the upper layer of the East Greenland Current. In recent years a great deal of interest has been attached to the heat budget of the Arctic, particularly with reference to climate and the distribution of sea ice and to their possible modification, either through agencies of nature or through those of man. The oceanic heat flux is an important factor in the Arctic heat budget. For example, the one-dimensional ice model of Maykut and Untersteiner [1969] indicates that for an upward oceanic heat flux in the Arctic basin exceeding about 5 kcal cm -•' yr -• the ice will vanish. We have therefore reexamined the advective exchange of heat and mass across the lateral boundaries of the Arctic Ocean (Figure 1) and synthesized new oceanic budgets; these budgets differ significantly from earlier constructions. The observational basis for our calculations includes numerous detailed current and

Ketazolam (both in once-daily and three-times-daily dosing), diazepam, and placebo were compared for effectiveness in relieving anxious symptomatology in a clinical trial conducted with a total of 222 anxious, non-psychotic outpatients. Results indicated that improvement occurred early in treatment, that ketazolam was equally effective in both once-daily and three-times-daily dosing, and that ketazolam was similar in effect to diazepam. Ketazolam (both once-daily and three-times-daily) and diazepam were significantly (P < 0.05) better than placebo in alleviating symptoms of anxiety, as measured by the Hamilton Anxiety Scale, the Covi Anxiety Scale, and a physician-rated measure of global improvement.
