Spotlight 1: Axial Seamount [PDF]

open access: yesOceanography, 2010
Axial Seamount is a hotspot volcano superimposed on the Juan de Fuca Ridge (JdFR) in the Northeast Pacific Ocean. Due to its robust magma supply, it rises ~ 800 m above the rest of JdFR and has a large elongate summit caldera with two rift zones that ...

Recent Seismic Studies at the East Pacific Rise 8°20'–10°10'N and Endeavour Segment: Insights into Mid-Ocean Ridge Hydrothermal and Magmatic Processes [PDF]

open access: yesOceanography, 2012
As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8°20'–10°10'N and Endeavour Segment of the Juan de Fuca ...

The geochemistry and geomicrobiology of relict hydrothermal sulphide deposits

open access: yes, 2000
The diagenetic re-mineralisation of seafloor-sulphide deposits and the role of microbes in the metal-exchange processes were investigated in metalliferous sediments from the Alvin relict hydrothermal zone in the TAG area at 26º8'N (Mid-Atlantic Ridge ...

The Electrical Properties of a 2D Conductive Zone underneath the Juan de Fuca Ridge

open access: yes, 1998
Vertical gradient electromagnetic sounding (VGS) on the Endeavour segment of Juan de Fuca mid‐ocean ridge reveals the presence of a 2D ridge‐parallel, conductivity anomaly.

Trace element distributions in ridge flank sediments from the east Pacific Rise, and their use as proxies of past ocean conditions

open access: yes, 2008
The eastern equatorial and tropical Pacific regions are areas of significant carbon fluxes from theatmosphere to the ocean interior. Changes in the function of marine biogeochemical cycles in thisregion potentially exert an important control on global ...
