To find the total depth of the scuba diver after an additional descent, we need to add the initial descent and the additional descent.
The initial dive puts the diver at a depth of -18 meters (since depths below the surface are usually represented as negative). He then descends an additional 39 meters:
\[
-18 + (-39) = -18 - 39 = -57 \text{ meters}
\]
So, the integer that represents his depth after the additional descent is:
**A** -57
