Chemistry, Temperature, and Faunal Distributions at Diffuse-Flow Hydrothermal Vents: Comparison of Two Geologically Distinct Ridge Systems [PDF]
Oceanography, 2012 Diffuse-flow, low-temperature areas near hydrothermal vents support life via chemosynthesis: hydrogen sulfide (and other reduced chemical compounds) emanating from the subsurface is oxidized with bottom-water oxygen through bacterial mediation to fix ...

Diffuse Flow On and Around Hydrothermal Vents at Mid-Ocean Ridges [PDF]
Oceanography, 2012 Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor.

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 ...

Larval Dispersal: Vent Life in the Water Column [PDF]
Oceanography, 2012 Visually striking faunal communities of high abundance and biomass cluster around hydrothermal vents, but these animals don't spend all of their lives on the seafloor.

Low-Temperature Hydrothermal Plumes in the Near-Bottom Boundary Layer at Endeavour Segment, Juan de Fuca Ridge [PDF]
Oceanography, 2012 Low-temperature (typically 5–75°C) fluid, commonly referred to as "diffuse" hydrothermal flow, emanates from fractures over a significant portion of the Juan de Fuca Ridge seafloor in the Northeast Pacific Ocean (Kelley et al., 2012, in this issue ...

Hydroacoustic Monitoring of Oceanic Spreading Centers: Past, Present, and Future [PDF]
Oceanography, 2012 Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean.

Origen del Alineamiento Submarino de Pascua: morfología y lineamientos estructurales [PDF]
, 2014 Indexación: Web of Science; Scielo.ABSTRACT. The Easter submarine alignment corresponds to a sequence of seamounts and oceanic islands which runs from the Ahu-Umu volcanic fields in the west to its intersection with the Nazca Ridge in the east, with a ...

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 ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Geochemistry, Geophysics, Geosystems, 2022 Along ultraslow spreading ridges melt is distributed unequally, but melt focusing guides melt away from amagmatic segments toward volcanic centers. An interplay of tectonism and magmatism is thought to control melt ascent, but the detailed process of ...
