Abstract: | A simple device for the measurement of length (or area) along an underwater transect is described. This instrument is pushed
or pulled by SCUBA divers along lake or river bottoms and the rotation of a paddle wheel is recorded on a digital counter.
The device eliminates the need for straight line and smooth bottom transects, and allows for greater versatility than that
provided by the more usual rope line transect. |
