TLDR
In this paper, it was shown that seafloor sediments that blanket the ocean floor are of widely varying thickness but seismic observations indicate that 200 to 400 meters in the Pacific and one kilometer in the Atlantic are fairly typical values for deep water.Abstract:
: The unconsolidated sediments that blanket the ocean floor are of widely varying thickness but seismic observations indicate that 200 to 400 meters in the Pacific and one kilometer in the Atlantic are fairly typical values for deep water. At present direct observation of these sediments is limited to such samples as may be recovered by dredging or coring operations, for drilling has been carried out only in the shallow waters of the coastal shelves. Knowledge of the physical properties of the great bulk of the sediments deeper than the few tens of feet reached by coring equipment is thus necessarily derived from geophysical observations.read more

Mantle-lithosphere bodies in the Alboran crustal domain (Ronda peridotites, Betic-Rif orogenic belt)
TL;DR: In this article, a gravity study showed that the gravity field is mainly the result of a combined effect of crustal thinning and the presence of ultramafic bodies in the western Betics.

An integrated gravity model for Europe's crust and upper mantle
TL;DR: In this paper, an integrated gravity model of the European lithosphere based on an analysis of a number of new data-sets, leading to a much higher resolution than provided by previous models.

TL;DR: In this paper, particle mass fluxes and sedimentation processes were investigated on the slope of the Aquitanian margin of the Bay of Biscay, between the canyons of Cap-Breton and Cap-Ferret.

Sound velocity in deep sea sediments
TL;DR: In this article, the relationship of velocity to porosity and to median diameter is more clearly defined, and the variations exhibited by atypical materials are explained by high percentage biogenic content that yielded a high porosity for any given median diameter.
