Depth: 78
Each item refers to the answer to a puzzle. From the puzzle you can see what depth the puzzle is that. You then use the puzzle depth and dive/surface times with the PADI dive table to get the letters.

Using PADI dive tables like the following (from http://www.scubatoronto.com):
a time and depth gives a decompression group letter. Then a “surface interval” time (given by the workshop puzzles which are on the surface) gives a new letter group. These are plugged into table 2:
Combined with the depth for the next dive, it gives residual minutes of nitrogen. Added to the minutes of the next dive, and plugged into table 1, this again gives a letter. For example, 97 minutes at 40 feet gives U. A surface interval of 27 minutes lowers it to N. On table 2, N at 60 feet (the depth of the second dive gives 35 remaining minutes. Added to the 14 minutes of the dive, gives 49 minutes at 60 feet, which in table 1, gives a T.
Follow this procedure to the end, alternating dives and surfaces, to get the answer, UNTANGLE LINES.
