Comments:
Superman mentions the disappearance of Mera in this story which indicates that it takes place during the Mera's Quest serial in Aquaman #40 through Aquaman #48. The only break in that storyline in which this story could chronologically take place is between Aquaman #40 and Aquaman #41.

Synopsis:
While reporting on the maiden voyage of a new atomic submarine, Jimmy Olsen rescues the crew when the sub is caught in a whirlpool. Aquaman then arrives to help save the submarine. The whirlpool was caused by Captain Bane, the disguised identity of the Old Man of the Sea.

Seeking revenge against Aquaman and Jimmy, the Old Man of the Sea arranges for Jimmy to gain Aquaman's powers. Then disguised as Superman he arranges for Jimmy and Aquaman to prove which is the best by taking them into the desert. Jimmy is barely able to stay alive, but Aquaman appears to die. The Old Man then strands Jimmy in the middle of the ocean without powers.

Superman apprehends the Old Man when he returns to Earth. He takes the trickster to a lifeless water world where he can't trouble Earth again. Superman also reveals that Aquaman survived when his body was returned to the ocean, the water revived it. Jimmy is also still alive having found a life preserver from the Titanic floating in the ocean.
