This is composed by bathymetry which is estimated by satellite altimetry, and from ship surveys. However, after modeling recent similar data bases and also processing and modeling available multibeam bathymetry with ~100% of spatial coverage, those highs seem to be absent. The apparent creation of bathymetric artifacts would have been due to the inclusion of bad single beam data of a specific ships sounding track. The hypothesis regarding the origin of the alignment associated with the vertical displacement of a block at the outer shelf, would not be valid. 2011 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47919988014 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.2 Vol.46 |
