echogram การใช้

High frequency echograms show that the top of the seamount is covered in sediment, but that the steep slopes are rocky.
In the following days, three scientific and seismic survey vessels studied the area : " Sarmiento da Gamboa " ( bathymetry, gravity and mapping seismic profiles ), " Ramon Margalef " ( multibeam bathymetric survey, sediment sampling and the acquisition of echograms of the water column ) and " Cornide de Saavedra " ( physical and chemical evolution of the volcano stain ).
