I extend the interferometric interpolation of ocean bottom seismic (OBS) data from two dimensional data to 3D data. The sparse OBS data are interferometrically correlated with the model-based Green’s functions for the sea-floor model to generate the densely recorded OBS traces, and a local matching filter is applied to reduce the artifacts in the interpolated data. Information about the source ...

Particulate biogenic barium (bio-Ba) fluxes obtained from three instrumented arrays moored in the Alboran Sea, the westernmost basin in the Mediterranean Sea, are presented in this study. The mooring lines were deployed over almost one year, from July 1997 to May 1998, and were equipped with sediment traps at ~500-700 m depth, ~1000-1200 m depth and 30 m above the sea floor (~1000-2200 m). The ...

Events of the Paleocene-Eocene boundary provide the clearest example to date of how a tectonic event may have global climatic consequences. Recent advances permit well-constrained stratigraphic determination of several events that occurred at that boundary, in chron C24R: a many-fold increase in sea-floor hydrothermal activity, a global warming, a reduction in the intensity of atmospheric circu...

We used simplifying assumptions to derive analytical formulae expressing the reflectance of shallow waters as a function of observation depth and of bottom depth and albedo. These formulae also involve two apparent optical properties of the water body: a mean diffise attenuation coefficient and a hypothetical reflectance which would be observed if the bottom was infinitely deep. The validity of...
