Abstract/Summary

This report forms part of a commissioned study of the seafloor surrounding Ascension Island undertaken by the British Geological Survey in partnership with the Ascension Island Government. This work has been funded by the Darwin Plus overseas conservation/biodiversity challenge funds programme. Project reference: DPR9S2\1018 BGS Report reference: OR/24/014 Project title: Bathymetry, and seafloor habitats within Ascension Island’s nearshore waters The United Kingdom Hydrographic Office (UKHO) have provided invaluable advice and data (HMS Protector – HI1571) and will be custodians of the multibeam collected for this project, ensuring the data is used beyond the timescales of this project. This report uses a template designed to cover the technical survey details requested by the UKHO for commissioned multibeam bathymetric surveys (Hydrographic Instructions - HI). The primary objective of this project was seabed geological and habitat mapping, so not all the elements required for a hydrographic instruction are covered or even appropriate due to the budget and time available. Some sections have been removed and we have also added more details when appropriate, particularly on the seabed sampling equipment and methodology (Part I – Seabed).
