Shallow submarine hydrothermal systems in the Aeolian Volcanic Arc, Italy [PDF]

open access: yes, 2009
The majority of known high-temperature hydrothermal vents occur at mid-ocean ridges and back-arc spreading centers, typically at water depths from 2000 to 4000 meters.

Chemistry, Temperature, and Faunal Distributions at Diffuse-Flow Hydrothermal Vents: Comparison of Two Geologically Distinct Ridge Systems [PDF]

open access: yesOceanography, 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]

open access: yesOceanography, 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.

Behavioral Modeling of IC Ports Including Temperature Effects [PDF]

open access: yes, 2002
The development of temperature-dependent macromodels for digital IC ports is addressed. The proposed modeling approach is based on the theory of discrete-time parametric models and allows one to estimate the model parameters from voltage and current ...

Larval Dispersal: Vent Life in the Water Column [PDF]

open access: yesOceanography, 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.

Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics [PDF]

open access: yes, 2017
Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the Cocos Ridge at the Middle ...

Low-Temperature Hydrothermal Plumes in the Near-Bottom Boundary Layer at Endeavour Segment, Juan de Fuca Ridge [PDF]

open access: yesOceanography, 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 ...

Crustal structure and rift flank uplift of the Adare Trough, Antarctica [PDF]

open access: yes, 2005
The Adare Trough, located 100 km northeast of Cape Adare, Antarctica, represents the extinct third arm of a Tertiary spreading ridge between East and West Antarctica. It is characterized by pronounced asymmetric rift flanks elevated up to over 2 km above

Hydroacoustic Monitoring of Oceanic Spreading Centers: Past, Present, and Future [PDF]

open access: yesOceanography, 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.

The late Mesozoic-Cenozoic tectonic evolution of the South China Sea: A petrologic perspective [PDF]

open access: yes, 2014
This paper presents a review of available petrological, geochonological and geochemical data for late Mesozoic to Recent igneous rocks in the South China Sea (SCS) and adjacent regions and a discussion of their petrogeneses and tectonic implications. The
