Indagini preliminari su ripartizione e morfologia della prateria a <i>Posidonia oceanica</i> nella rada di Alghero = Preliminary investigations on distribution and morphology of a <i>Posidonia oceanica</i> meadow in the bay of Alghero

Abstract

An extensive side scan sonar survey has been conducted in the gulf of Alghero (N Sardinia, Italy) in order to map the main morphological and habitat features of the seafloor. The local Posidonia oceanica meadow covers a total area of 13 km2, extending from 2.5 to 35 meters depth and is medially divided by an ancient river channel developed during the last glacial stage
