Titanica is a 1992 IMAX documentary film about the RMS "Titanic".

 It was the second feature length IMAX film released, following "Stones at the Max" in 1991.
 An edited 40 minute version of the film was also later released for IMAX theatres in 1995; this version had new narration by Leonard Nimoy, though it retains most of White's narration.

9 North, or Nine North, is a region of hydrothermal vents on the East Pacific Rise in the Pacific Ocean, 900 kilometers off the coast of Acapulco, Mexico; it has been so named by scientists because its latitude is 9°50' N.
 It was first seen to erupt in 1991 by the deep submersible "Alvin" during a survey for the Ocean Drilling Program.
 In November 1999, scientists, students, education specialists, and film crews returned to 9 North to see how the biology and landscape had changed over time.
 IMAX, National Geographic, and BBC film crews have made videos about the vents at 9 North, most noticeably "Volcanoes of the Deep Sea".
Collaborative Research Into Small Arms Technology (CRISAT) is the name of a series of studies conducted by the North Atlantic Treaty Organisation (NATO), identifying and defining threats with regard to the standardisation in the manufacturing of military equipment.
 The CRISAT target is defined as a 1.6 mm titanium (UK IMI Ti 318) plate supplemented by 20 layers of Kevlar (UK/SC/4468) as defined in STANAG 4512.
 This target is intended to replicate the personal protection used by former Warsaw Pact countries, and it is still used as a reference.
 The CRISAT target will stop the commonly used 9×19mm Parabellum full metal jacket cartridge, but it is pierced by the newer 5.7×28mm and 4.6×30mm personal defense weapon cartridges at ranges in excess of 200 meters.
