摘要
We use the 2021 GEBCO grid to interpret the seabed geomorphology within the Cook Islands and adjacent areas. A complex geological history dating back to 125 Ma is manifested in a range of geoforms. These include abyssal plains, plateaux, volcanic and tectonic rises, seamount-knolls and chains and troughs, as well as fault zones. A Main Map at 1:3,000,000 scale is presented with example cross-sections, with 1:10,000,000 scale inset maps of bathymetry, mineral occurrences (the Cook Islands has a major polymetallic nodule resource), feature names and regional setting. We expect these map products to be of value to stakeholders interested in exploration and mineral resource assessment, marine habitat management, and the general make-up of this small island large ocean country.
