Seabed Classification at Ocean Margins

  • Ph. Blondel
Chapter

Abstract

Ocean margins have become the focus of numerous geophysical and environmental surveys, because of their economic, scientific and oceanographic significance. These surveys deliver increasingly larger volumes of data, acquired by many types of techniques and sensors. Despite their importance, most of these data are still interpreted visually and qualitatively by skilled interpreters. Human interpretation is time-consuming and difficult to standardise; and, in certain conditions, it can be error-prone. Current research in data processing is shifting toward computerbased interpretation techniques, and in particular seafloor classification. After a brief review of the main characteristics of ocean margins, the different notions of classification will be presented, along with the desired aims. These will be followed by a review of non-acoustic and acoustic (mainly sonar) classification techniques, supplemented with actual examples when applicable. Seabed classification, in general and at ocean margins, is fast becoming a major tool in seafloor surveying and monitoring. The last section will assess the latest tendencies and the technical developments that can be expected in the near future.
