Abstract Trace fossil communities are mainly bathymetry-controlled. Their relative depth sequence has been established in sedimentary series of up to Cambrian age. Actual depth figures can now be added from counterparts in the present oceans. As exemplified by the spreite burrows, behavioural response to a bathymetric gradient in food suply is ...

The two previous chapters described how depth measurements are made and elaborated on the accuracy and strengths of each type of data. Clearly, it would be wonderful if the entire world ocean were covered with multibeam data, but at the present time, there is only limited coverage; only a few ships are equipped with multibeam, and their speed remains ...

The previous chapter (Chapter 2) presented basic acoustic theory, from the generation of a sound wave to its scattering on/in the seabed and its reception by the sonar platform. Acoustic pressures are used to quantify the response of the seabed at the particular frequency used. These backscatter measurements are combined across-track to create a swath,
