That's 96 feet DOWN from the lake surface, and then 49 feet towards the surface. His depth would be -96+49 feet, or -47 feet, where the surface would be 0 feet, down is negative and up is positive.

0 = Surface level

Beneath means subtraction.
0 - 96 = -96

Climbs means addition.

-96 + 49 = -47

The scuba diver is -47 feet beneath the surface of the lake.
