An instrument has been designed which records the orientation of coring devices and other apparatus with respect to magnetic north, and can be used in any depth of water.
Orientation data on Recent marine structures from depths greater than shelf depth have not been obtained in routine fashion in previous studies, thus omitting an important factor of considerable stratigraphic importance. Paleodirectional studies have few modern marine counterparts.
Examples of oriented samples are described from test stations in the San Pedro basin.
