Hi Riannon
Consider the diagram below
Ocean Surface---------~~~~~~~~~~~~~~~~ 0 ft ~~~
| |
| |
| |
| |
| |
| |
| -259 ft Peak - 223 ft
| | |
| | |
| | |
| | |
| | |
| | 153 ft :)| diver location

---------------------------- Ocean Floor-----------------------------------
The peak is 153 ft relative to the ocean floor
The peak is then -259 + 153 = -106 ft relative to the ocean surface
The location of the diver relative to the peak of the rock formation is -106 ft - (-223 ft) = 117 ft
