Abstract:
The multibeam data set was acquired in 2021 during the Instituto Hidrográfico cruise HI 09A/20 under the guideance of Captain Franco Leitão, and is originally available through the website (https://gridmarcv.hidrografico.pt/) but also at the IHO Data Centre for Digital Bathymetry (https://www.ngdc.noaa.gov/iho/). The hydrographic survey was carried out with the NRP ALMIRANTE GAGO COUTINHO, equipped with the EM 710 and EM120 multibeam sounding systems. Positioning was assured by a SEAPATH 330+ system from SMF KONGSBERG EM710/EM120, GNSS data. Depth values are referred to ZH (0.80m from the Average Level adopted in Cape Verde). Information on data processing is unavailable as we are not the orignial authors of this data set but re-issue it by permission. The original ungridded data set contained in the .txt file was gridded to a 25m cell size using GlobalMapper, and is submitted here as an ascii grid file.
