The strength of that pressure may depend in part on the psychological impact of fresh discoveries about the diversity of ocean life.

Maarten Van Sluys, another member of the Brazilian victims' family association, said there was also concern about the condition of the black boxes after two years sitting in corrosive seawater under immense pressure, nearly 4km (2.5 miles) below the surface of the ocean.
