Guam - The Mermaid Sapphire is back on Guam with her crew of 59 including scientists and Hollywood film director James Cameron and of course the Deep Sea Challenger - the lime green mini submarine used by Cameron to dive the Challenger Deep - the deepest point on earth.

He accomplished that historic 3-hour dive last month, and announced more dives in the future. The Mermaid Sapphire pulled into Apra Harbor just a little after nine o'clock this morning and will be joined by her accompanying ship Barracuda that will dock in Guam tomorrow. According to the Ambyth representatives, the two ships are only on Guam to unload equipment at the University of Guam Marine Lab. According to UOG Marine Lab Director Laurie Raymundo they will be providing logistical support Friday morning.  Raymundo added a Memorandum of Understanding will be signed Monday between UOG and the Scripps Institution of Oceanography which will provide research, study and funding opportunities.

The Mermaid Sapphire arrived this morning from Ulithi.

Meanwhile according to Cameron's latest post on Twitter, his sub's co-designer Ron Allum made his first dive down challenger deep Sunday, diving 3,600 feet..."he dove the sub like a champ".
