Tectonic structures on the Juan de Fuca Ridge
Geological Society of America Bulletin, 1977 The northern Juan de Fuca Ridge is an actively spreading part of the East Pacific Rise system that is flooded with young turbidite sediments from the nearby continental margin. A detailed geophysical survey was completed at the intersection of the ridge with the Sovanco Fracture Zone.

Propagation as a mechanism of reorientation of the Juan de Fuca Ridge
Journal of Geophysical Research: Solid Earth, 1984We present a revised model of the tectonic evolution of the Juan de Fuca ridge by propagating rifting. The new model has three different relative rotation poles, covering the time intervals 17.0–8.5 Ma, 8.5–5.0 Ma, and 5.0 Ma to the present. The rotation pole shifts at 8.5 and 5.0 Ma imply clockwise shifts in the direction of relative motion of 10° to ...

Sedimentation, stratigraphy and physical properties of sediment on the Juan de Fuca Ridge
Marine Geology, 2016 Sedimentation near mid-ocean ridges may differ from pelagic sedimentation due to the influence of the ridges' rough topography on sediment deposition and transport.

The distribution of geothermal fields on the Juan de Fuca Ridge
Journal of Geophysical Research: Solid Earth, 1985Near bottom water temperatures were mapped along 400 km of the strike of the Juan de Fuca Ridge as part of a combined Sea MARC/Seabeam experiment to image the variability of morphology and structure along a spreading center segment. The water temperature data collected by a continuously towed thermistor chain, in addition to salinity data, indicate ...

Hydrothermal effects west of the Juan de Fuca Ridge
Deep Sea Research Part I: Oceanographic Research Papers, 1993The Juan de Fuca Ridge in the northeast Pacific Ocean is a region of extensive hydrothermal activity, and plumes emanating from the ridge can be dispersed by the oceanic circulation at about 2000 m. Off-axis temperature-salinity characteristics and water-property maps suggest a history of variability in hydrothermal activity on the ridge.

EMRIDGE: The electromagnetic investigation of the Juan de Fuca Ridge
Marine Geophysical Researches, 1993From July to November 1988, a major electromagnetic (EM) experiment, known as EMRIDGE, took place over the southern end of the Juan de Fuca Ridge in the northeast Pacific. It was designed to complement the previous EMSLAB experiment which covered the entire Juan de Fuca Plate, from the spreading ridge to subduction zone.
