Microearthquake studies of the Blanco fracture zone and Gorda Ridge using Sonobuoy arrays

Creator:: Jones, Paul Roy III
Abstract:: University deployed two arrays of three sonobuoys over the Blanco fracture zone and two arrays of four sonobuoys over the Gorda ridge to detect and locate microearthquakes. Microearthquake activity predicted by plate tectonic theory for the Blanco fracture zone and Gorda ridge was observed by these arrays to originate from...

Microseismicity on the Gorda Ridge

Creator:: Solano-Borrego, Ariel E.
Abstract:: The seismicity at the northern section of the Gorda Ridge has been studied with Ocean Bottom Seismographs. Nearly one hundred earthquakes were located with RMS travel time residuals less than 0.5 seconds. Most of these events lie within or near the array and they are probably associated with the dynamics...

A mesoscale study of coastal currents and upwelling off Peru

Creator:: Enfield, David B.
Abstract:: Moored instrument records, drogue displacements, and hydrographic observations are used in describing the coastal currents and upwelling off Peru. The data were obtained over the continental shelf near 15°S. during a two week study in late March and early April of 1969. First order statistics and graphical representations of current...

Comparison of sea level and currents off the Oregon coast using mean monthly data

Creator:: Marthaler, James Gordon
Abstract:: Sea level and current data collected near Newport, Oregon are compared to determine an empirical relationship from which the low frequency (f < .1 cpd) alongshore current field over the continental shelf is estimated from observed sea level measurements at the coast. Regression analysis of the near-surface (20-25 m) currents...

Vertical current measurement in the Oregon coastal upwelling region

Creator:: Deckard, Dennis E.
Abstract:: Direct measurements of vertical water motions were made in the Oregon coastal region during the 1972 summer upwelling season. The instruments used were the Webb-Voorhis vertical current meters which are freely drifting neutrally buoyant floats capable of sensing vertical motion. It was found that in the region studied, water tended...

Near-inertial motions off the Oregon coast

Creator:: Anderson, Iain
Abstract:: Nearly three months of current meter records from five moorings off the Oregon coast taken between October 1977 and January 1978 were analyzed for near-inertial motions. The moorings were located from the midshelf out to the foot of the continental slope, spanning the continental margin. All but two of the...
