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

Integrated geophysical modelling of the northern Cascadia subduction zone
TL;DR: In this article, an integrated interpretation of geophysical and geological data has been conducted for the northern Cascadia subduction zone, where surface geology, physical properties, and seismic reflection, refraction, heat flow, borehole, magnetotelluric, and seismicity data have provided constraints on structure and composition.

Evolution of the Lofoten‐Vesterålen margin inferred from gravity and crustal modeling
TL;DR: In this article, a boudinage mechanism was proposed to explain the generation of these density anomalies and respective crustal layer undulations, which can be explained by the crustal density anomalies that are observed.

Gravity modelling along the Southern Segment of the European Geotraverse from the Gulf of Genoa to the Swiss Molasse Basin
TL;DR: In this article, a profile running along the northern part of the Southern Segment of the European Geotraverse was modelled using gravity maps recently published in Italy and Switzerland.

The Nares Strait gravity anomaly and its implications for crustal structure
H. R. Jackson,L. Koppen +1 more
TL;DR: A negative free-air gravity anomaly is associated with Nares Strait, the waterway that separates Ellesmere Island and Greenland as discussed by the authors, and two-dimensional crustal models were created to identify the cause of the anomaly.

Tectonic evolution and crustal structure of the central Indonesian region from geology, gravity and other geophysical data
TL;DR: The Central Indonesian Region (CIR) as discussed by the authors represents a transition between the largely Eurasian elements of Western Indonesia and the Pacific and Australian related elements of Eastern Indonesia and is bounded by two major subduction zones; in the west by pre-Tertiary subduction zone at the southeastern margin of the Sundaland, and to the east by the Early Tertiary Subduction zone.
