term seasonal cycle was used to remove seasonal effects. Most of the averages involve four stations; the error bars are the standard deviations of the 0-150 m mean values for the contributing stations for each case. The primary survey takes place in spring or early summer. The occasional fall and winter occupations included in Figure 5 are consistent with the other values. The average temperature over the past three years ( 003005) is more than 1 C warmer than the average during the cold period of 1990-1994 that ended with two years of intense deep convection. The early 1990s were anomalously cool. The most recent decade shows a warming trend, with interannual variability on shorter time scales. OWS Bravo measurements from 1963 to 1974 showed a decade-long cooling trend of similar magnitude, leading to a resumption of deep convection in the two winters before the abandonment of the weather station (Lazier 1980). Continued monitoring of the AR7W section is one means of resolving whether the recent trend is related to natural decadal variability, global warming, or a combination of both.
