What is "everblue"

Everblue is an adventure game based on scuba diving. It is the first of the Everblue series and was followed by Everblue 2. It was released in Japan and Europe, but not in North America. It predates developer Arika's 2007 game Endless Ocean (Forever Blue in Japan). Both games share similar a theme of underwater scuba diving and photography, though Endless Ocean presented a third person perspective and significantly less focus on salvaging or ship. In 2002 it received a sequel, Everblue 2.
