Geochemical expression of volcanism in an on-axis and intraplate hotspot : Cobb and Marquesas

Creator:: Desonie, Dana L.
Abstract:: The Pacific Ocean basin is home to a set of hotspots diverse in their eruption rate, duration of volcanism, and basalt chemistry. Pacific hotspots are found in a spectrum of distinct plate tectonic settings, from near a spreading ridge to intraplate. Cobb hotspot, which resulted in formation of the Cobb-Eickelberg...

The petrology, geochemistry, and geochronology of hotspot seamounts in the North Pacific and arc/backarc volcanism on the northern Antarctic Peninsula

Creator:: Keller, Randall A.
Abstract:: Volcanic rocks from hotspots and island arcs/backarcs typically have enriched trace element and isotopic compositions that contain a contribution from subducted oceanic crust. Isotopic and trace element data suggest that the enriched components in hotspot volcanism are ancient subducted sediment and crust, and the enriched components in arc/backarc volcanism are...

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...
