Abstract

Abstract

Cobalt-rich ferromanganese crusts are mainly distributed around the top brim and on the slope of Mid-Pacific seamounts and West Pacific seamounts. Calcium-pelagic sediment, carbonate rock and debris flow driven by gravity process are main seafloor sediment types of seamounts, which control the distribution of cobalt-rich ferromanganese crusts. In this paper, multibeam backscatter intensity data from EM122 multibeam system are first used in China to recognize seafloor geological types of Qianyu seamount on Mid-Pacific seamounts. Backscatter data are processed and classified statistically with verification of sub-bottom profile and ground-truthing data to identify four seafloor geological types including cobalt-rich crust, calcium-pelagic sediment, carbonate rock and debris flow. Different backscatter intensities are represented by different seafloor geological types, cobalt-rich crust area shows as uniform strong backscatter intensity representing, and calcium-pelagic sediment area shows as uniform weak backscatter, their backscatter difference is about 20 dB. The top of Qianyu seamount is mostly outcropped by carbonate rock, and locally covered by calcium-pelagic sediment, and cobalt-rich crust distribute around the top brim and southern and eastern slope ridges. Furthermore, three gravity slide areas are recognized on the Qianyu seamount, which are of debris flows.
- backscatter intensity,
- cobalt-rich crust,
- Qianyu seamount,
- seafloor geological classification,
- marine geology,
- geophysics
