    Abstract An autonomous underwater vehicle (AUV) carrying a multibeam sonar and a chirp profiler was used to map sections of the seafloor within the La Jolla Canyon, offshore southern California, at sub-meter scales. Close-up observations and sampling were conducted duri...

    Trajectories of satellite-tracked surface drifters released in the continental margin area west of Kyushu indicate a separation of the inshore side of the Kuroshio that appears to form the beginning of the Tsushima Current. The trajectories also indicate an anticyclonic...

    The Japan Sea is a major marginal sea in the western Pacific comprised of basins and bathymetric highs. Technically, these features were created by multiple-rifting and spreading processes, as exemplified in the creation of the Japan Basin and Yamato Basin. However, the...

    Abstract The spatial organization and scaling properties of a number of physical variables in river basins are analyzed within the framework of the multifractal formalism using data from digital elevation maps. These variables include energy expenditure, slopes, dischar...

    A new measurement techique based on a model of a Gaussian seamount loading a thin elastic lithosphere was developed to analyze seamounts that, until then, were not surveyed or seamounts with poor bathymetric coverage. The model predicts that the seamount diameter is equ...

    Abstract Relatively undisturbed surficial sediment samples from three sedimentary provinces (pelagic, turbidite dominated and hemipelagic) in the Venezuela Basin were examined for spatial variability in water content and undrained shear strength. A miniature vane shear ...

    Abstract The carbonate edifice of the Maldives has an exceptional record of the global climate and ocean current reconfigurations during the Neogene that set the path for the establishment of the present-day global climate system. The study of seismic profiles, sediment...

    Abstract A high-resolution unstructured-grid global-regional nested ice-current coupled FVCOM system was configured for the Arctic Ocean and used to examine the impact of model resolution and geometrical fitting on the basin-coastal scale circulation and transport in th...

    Abstract Free-air, Bouguer and isostatic gravity anomalies of the Arctic regions, derived from 350,000 irregularly distributed gravity observations, were gridded at a 10 km interval and plotted against rock-equivalent topography. All of these anomalies show various degr...
