Sediment echosounder profiles were collected during the EUROLEON cruise in 2007 with the Spanish research vessel BIO Hespérides using a SIMRAD TOPAS PS018 system. Real-time processing of the data consists of basic filters and gain control. Data were recorded both in the native system and in SEGY format. The data is projected to UTM WGS 1984 31N.
