Oblique seafloor spreading across intermediate and superfast spreading centers
Earth and Planetary Science Letters, 2018 Abstract We show that oblique seafloor spreading occurs in several regions where obliquity, α, was not recognized before. These include the slow spreading centers of the Red Sea ( α ≈ 20 ° ), intermediate spreading centers of the Cocos–Nazca plate boundary between 91°W and 94°W ( α ≈ 9 ° ), and superfast spreading centers of the East ...

Geochemistry, Geophysics, Geosystems, 2011 Most hydrothermal systems at oceanic spreading centers are underlain by basaltic magma bodies; however, some are underlain by higher‐silica magmas such as andesite or dacite.

Geodynamic Models of Melt Generation and Extraction at Mid-Ocean Ridges [PDF]
Oceanography, 2012 It is widely accepted that plate divergence at mid-ocean ridges drives mantle flow, mantle melting, and the formation of new oceanic crust. However, many of the details of this process remain obscure because of the inaccessibility of the mantle to direct

Hydrothermal activity and magma genesis along a propagating back-arc basin: Valu Fa Ridge (southern Lau Basin) [PDF]
, 2006 Valu Fa Ridge is an intraoceanic back-arc spreading center located at the southern prolongation of the Lau basin. Bathymetric observations as well as detailed sampling have been carried out along the spreading axis in order to trace hydrothermal and ...

Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets [PDF]
Oceanography, 2012 Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate approaches are sometimes needed.

Links from Mantle to Microbe at the Lau Integrated Study Site: Insights from a Back-Arc Spreading Center [PDF]
Oceanography, 2012 The Lau Integrated Study Site (ISS) has provided unique opportunities for study of ridge processes because of its back-arc setting in the southwestern Pacific. Its location allows study of a biogeographical province distinct from those of eastern Pacific

Actin, α-actinin, and tropomyosin interaction in the structural organization of actin filaments in nonmuscle cells [PDF]
, 1975 During the spreading of a population of rat embryo cells, approximately 40% of the cells develop a strikingly regular network which precedes the formation of the straight actin filament bundles seen in the fully spread out cells.

Oceanography, 2012 It is with especially great pleasure, and a bit of nostalgia, that I introduce the March 2012 special issue of Oceanography on "Oceanic Spreading Center Processes: Ridge 2000 Program Research." My very first oceanographic cruise was to the Juan de Fuca ...

The Dynamical Dipole Mode in Dissipative Heavy Ion Collisions [PDF]
, 2000 We study the effect of a direct Giant Dipole Resonance ($GDR$) excitation in intermediate dinuclear systems with exotic shape and charge distributions formed in charge asymmetric fusion entrance channels. A related enhancement of the $GDR$ gamma yield in
