Abstract

The DTM is a compilation of multibeam echosounder surveys at Central Aegean Sea - around Santorini Island (Greece), acquired with R/V Aegaeo using Seabeam 2120 (20 kHz) echosounder during 2001, 2006, 2016 and 2017 cruises. Grid resolution is 1/32 arc-minutes processed for the purpose of the HR DTMs layer of EMODnet Bathymetry HRSM, October 2018.
