In 2001, we revisited thickly sedimented 5.9 Ma crust on the southern flank of the Costa Rica Rift for wireline re-entry of two important ocean crustal boreholes, Holes 504B and 896A, more than 8 years after they were last drilled in 1993. Here we re

FFT beamforming is typically applied to arrays of coplanar and equally spaced elements. For curved arrays, conventional delay and sum beamforming should be the norm because the elements are not coplanar and the projection of their position on a tange

Bottom‐looking sonars operating at frequencies greater than 30 kHz transmit acoustic signals which penetrate at most a few meters into seafloor sediments, making them well suited to characterize the water/sediment interface. Acoustic wavelengths at

A temporal model of high‐frequency (10–250 kHz) seafloor acoustic backscatter has been developed which simulates the average squared echo envelope from a monostatic echo sounder. Tests comparing the model to measured backscatter echoes from pelag

Over the past 3 years, a multisensor digital Deep Tow vehicle has been developed at the Marine Physical Laboratory to carry out fine‐scale measurements near the seafloor down to 6000 m depth. The suite of sensors include: a pair of 110‐kHz side
