英文摘要	Massive seamounts have been surveyed and documented in the last decades. However, the morphologies of seamounts are usually described in qualitative manners, yet few quantitative detections have been carried out. Here, based on the high-resolution multi-beam bathymetric data, we report a recently-surveyed guyot on the Caroline Ridge in the West Pacific, and the large-scale volcanic structures and small-scale erosive-depositional landforms in the guyot area have been identified. The multifractal features of the guyot are characterized for the first time by applying multifractal detrended fluctuation analysis on the surveyed bathymetric data. The results indicate that the multifractal spectrum parameters of the seafloor have strong spatial dependency on the fluctuations of local landforms. Both small- and large-scale components contribute to the degree of asymmetry of the multifractal spectrum (B), while the fluctuations of B are mostly attributed to the changes in small-scale roughness. The maximum singularity strength (alpha(0)) correlates well with the roughness of large-scale landforms and likely reflects the large-scale topographic irregularity. Comparing to traditional roughness parameters or monofractal exponents, multifractal spectra are able to depict not only the multiscale characteristics of submarine landforms, but also the spatial variations of scaling behaviors. Although more comparative works are required for various seamounts, we hope this study, as a case of quantifying geomorphological characters and multiscale behaviors of seamounts, can encourage further studies on seamounts concerning geomorphological processes, ocean bottom circulations, and seamount ecosystems.
