News stories from today's press conference are starting to appear. This one contributes no new information, but has some nice pictures, including some in the side bar to the right.

says:
On board the vessel will be three mini-submarines REMUS 6000, the same that allowed the location of the wreck of the Titanic.
which is not correct, considering that the wreck was located in 1985; perhaps this is a translation error. However, the REMUS 6000s did visit the Titanic last summer to participate in a survey of the wreck and debris field.
EDIT:
This German article has better technical information and gives the viewpoint from IMF-GOMAR, who are providing one of the REMUS-6000s. I think all of this information is known in this group.
