Search
Further information: Underwater searchesUnderwater searches, much like above water searches, are designed around specific search patterns. The most common forms of underwater search patterns are:
- Circular search
- Jackstay search
- Expanding square search
- "U" pattern search
The patterns are usually performed by divers in pairs or teams below the water, but they can also be conducted by use of a tender who may be a snorkeller at the surface, a person on a towing boat, or a person located on the shore.
In simple search operations, the patterns will usually be conducted by the divers simply looking visually for the object. In more sophisticated search operations, underwater magnetometers or hand held sonar may be used.

Famous quotes containing the word search:
“We spent them not in toys, in lusts, or wine,
But search of deep Philosophy,
Wit, Eloquence, and Poetry,
Arts which I loved, for they, my Friend, were thine.”
—Abraham Cowley (1618–1667)
“Adolescents are travelers, far from home with no native land, neither children nor adults. They are jet-setters who fly from one country to another with amazing speed. Sometimes they are four years old, an hour later they are twenty-five. They don’t really fit anywhere. There’s a yearning for place, a search for solid ground.”
—Mary Pipher (20th century)
“The danger lies in forgetting what we had. The flow between generations becomes a trickle, grandchildren tape-recording grandparents’ memories on special occasions perhaps—no casual storytelling jogged by daily life, there being no shared daily life what with migrations, exiles, diasporas, rendings, the search for work. Or there is a shared daily life riddled with holes of silence.”
—Adrienne Rich (b. 1929)
