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 ).
