Abstract

A comparison of object detection capability of side scan sonar, multibeam sonar, and Lidar was conducted by NOAA in Long Island Sound. The seafloor is characterised by thousands of glacial erratics-boulders varying in size from cobbles to 10m on a side. The water turbidity varies from Secchi depth of 3.5m to 6m. A set of 93 features was selected from the side scan data and was compared with data from the multibeam sonar and the Lidar. The percentages of targets detected by the different systems were compared as a function of target size, target height, and water depth.

Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form. In such cases referred material can be cited using numbered superscripts in the text and the list of references thus replaced by a section headed 'Notes' in which explanation of the superscripts is given. Material which has been consulted but not specifically referred to in the text can be included in a separate 'Bibliography'.
