Depth‐dependent permeability and heat output at basalt‐hosted hydrothermal systems across mid‐ocean ridge spreading rates
Barreyre, Thibaut; Olive, Jean-Arthur; Crone, Timothy; Sohn, Robert (Journal article; Peer reviewed, 2018)The permeability of the oceanic crust exerts a primary influence on the vigor of hydrothermal circulation at mid‐ocean ridges, but it is a difficult to measure parameter that varies with time, space, and geological setting. ... -
Discovery of active off-axis hydrothermal vents at 9° 54′N East Pacific Rise
McDermott, Jill M.; Parnell-Turner, Ross; Barreyre, Thibaut; Herrera, Santiago; Downing, Connor C.; Pittoors, Nicole C.; Pehr, Kelden; Vohsen, Samuel A.; Dowd, William S.; Wu, Jyun-Nai; Marjanović, Milena; Fornari, Daniel J. (Journal article; Peer reviewed, 2022)Comprehensive knowledge of the distribution of active hydrothermal vent fields along midocean ridges is essential to understanding global chemical and heat fluxes and endemic faunal distributions. However, current knowledge ... -
Extent and Volume of Lava Flows Erupted at 9°50′N, East Pacific Rise in 2005–2006 From Autonomous Underwater Vehicle Surveys
Wu, Jyun-Nai; Parnell-Turner, Ross; Fornari, Daniel J.; Kurras, Gregory; Berrios-Rivera, Natalia; Barreyre, Thibaut; McDermott, Jill M. (Journal article; Peer reviewed, 2022)Seafloor volcanic eruptions are difficult to directly observe due to lengthy eruption cycles and the remote location of mid-ocean ridges. Volcanic eruptions in 2005–2006 at 9°50′N on the East Pacific Rise have been well ... -
Hydrothermal fluid flow triggered by an earthquake in Iceland
Geoffroy, Laurent; Dorbath, Catherine; Ágústsson, Kristján; Kristjánsdóttir, Sigríður; Flóvenz, Ólafur G.; Doubre, Cécile; Gudmundsson, Ólafur; Barreyre, Thibaut; Bazin, Sara; Franco, Aurore (Journal article; Peer reviewed, 2022)Microearthquake hypocenters were analyzed in the Krýsuvík geothermal area in SW-Iceland with data taken from two consecutive passive seismic surveys, 2005 and 2009. Five years prior to the 2005 survey, this area was struck ... -
Investigating Fine‐Scale Permeability Structure and Its Control on Hydrothermal Activity Along a Fast‐Spreading Ridge (the East Pacific Rise, 9°43′–53′N) Using Seismic Velocity, Poroelastic Response, and Numerical Modeling
Marjanović, Milena; Barreyre, Thibaut; Fontaine, Fabrice; Escartín, Javier (Peer reviewed; Journal article, 2019)Along with the intracrustal heat source, crustal permeability is considered as the controlling factor for hydrothermal circulation within zero‐age oceanic crust. To obtain fine‐scale, 2‐D models of upper crustal permeability ... -
The Role of On- and Off-Axis Faults and Fissures During Eruption Cycles and Crustal Accretion at 9°50′N, East Pacific Rise
Wu, Jyun-Nai; Parnell-Turner, Ross; Fornari, Daniel J.; Berrios-Rivera, Natalia; Barreyre, Thibaut; McDermott, Jill M. (Journal article; Peer reviewed, 2023)Fissures and faults provide insight into how plate separation is accommodated by magmatism and brittle deformation during crustal accretion. Although fissure and fault geometry can be used to quantify the spreading process ... -
Significance of Short-Wavelength Magnetic Anomaly Low Along the East Pacific Rise Axis, 9°50′N
Berrios-Rivera, Natalia; Gee, Jeffrey S.; Parnell-Turner, Ross; Maher, Sarah; Wu, Jyun-Nai; Fornari, Daniel; Tivey, Maurice; Marjanović, Milena; Barreyre, Thibaut; McDermott, Jill (Journal article; Peer reviewed, 2023)Magnetic anomaly variations near mid-ocean ridge spreading centers are sensitive to a variety of crustal accretionary processes as well as geomagnetic field variations when the crust forms. We collected near-bottom vector ... -
Structure and metabolic potential of the prokaryotic communities from the hydrothermal system of Paleochori Bay, Milos, Greece
Moine-Bauer, Sven Le; Lu, Guang-Sin; Goulaouic, Steven; Puzenat, Valentine; Schouw, Anders; Barreyre, Thibaut; Pawlowsky-Glahn, Vera; Egozcue, Juan José; Martelat, Jean-Emmanuel; Escartin, Javier; Amend, Jan P.; Nomikou, Paraskevi; Vlasopoulos, Othonas; Polymenakou, Paraskevi; Jørgensen, Steffen Leth (Journal article; Peer reviewed, 2023)Introduction: Shallow hydrothermal systems share many characteristics with their deep-sea counterparts, but their accessibility facilitates their study. One of the most studied shallow hydrothermal vent fields lies at ... -
Unveiling the inherent physical-chemical dynamics: Direct measurements of hydrothermal fluid flow, heat, and nutrient outflow at the Tagoro submarine volcano (Canary Islands, Spain)
Martín-Díaz, Juan Pablo; González-Vega, Alba; Barreyre, Thibaut; Cornide, Bernardo; Arrieta, Jesús M.; Vázquez, Juan-Tomás; Palomino, Desirée; Lozano Rodríguez, José A.; Escánez-Pérez, José; Presas-Navarro, Carmen; Fraile-Nuez, Eugenio (Journal article; Peer reviewed, 2024)Tagoro is one of the few submarine volcanoes in the world that has been monitored since its early eruptive stage in 2011 to present day. After six multidisciplinary oceanographic cruises conducted between 2014 and 2023 to ...
