Acoustically Navigated Geological Underwater Survey
Encyclopedia
The Acoustically Navigated Geological Underwater Survey (ANGUS) is a deep-towed still-camera sled operated by the Woods Hole Oceanographic Institute and can be fitted with three 35 mm
color cameras with 400 feet (121.9 m) of film. It is capable of working in depths up to 20000 feet (6,096 m). and can remain in the deep ocean
for work sessions of 12 to 14 hours at a time, taking up to 16,000 photographs in one session.
It has been used to search for and photograph underground geyser
s and the creatures living near them and is equipped with a heat sensor to alert the tether-ship when it passes a one. It was also used, along with Argo
, to survey the wreckage of the Titanic.
35 mm film
35 mm film is the film gauge most commonly used for chemical still photography and motion pictures. The name of the gauge refers to the width of the photographic film, which consists of strips 35 millimeters in width...

Deep sea
The deep sea, or deep layer, is the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1000 fathoms or more. Little or no light penetrates this part of the ocean and most of the organisms that live there rely for subsistence on falling organic matter...

Geyser
A geyser is a spring characterized by intermittent discharge of water ejected turbulently and accompanied by a vapour phase . The word geyser comes from Geysir, the name of an erupting spring at Haukadalur, Iceland; that name, in turn, comes from the Icelandic verb geysa, "to gush", the verb...

Argo (submersible)
Argo is an unmanned deep-towed undersea video camera sled developed by Dr. Robert Ballard through Woods Hole Oceanographic Institute's Deep Submergence Laboratory. Argo is most famous for its role in the 1985 discovery of the wreck of the RMS Titanic...
