How many vent fields? New estimates of vent field populations on ocean ridges from precise mapping of hydrothermal discharge locations
Autor: Edward T. Baker, J. William Lavelle, Fernando Martinez, Rachel M. Haymon, Vicki Lynn Ferrini, Verena Tunnicliffe, Ko-ichi Nakamura, Joseph A. Resing, Sharon L. Walker
Publikováno v: Earth and Planetary Science Letters. 449:186-196
Decades of exploration for venting sites along spreading ridge crests have produced global datasets that yield estimated mean site spacings of ∼ 12 – 220 km . This conclusion demands that sites where hydrothermal fluid leaks from the seafloor are

EARTH AND PLANETARY SCIENCE LETTERS, vol 450
Numerous field, laboratory, and modeling studies have explored the flows of fluid, heat, and solutes during seafloor hydrothermal circulation, but it has been challenging to determine transport rates and flow directions within natural systems. Here w

Evidence for hydrothermal Archaea within the basaltic flanks of the East Pacific Rise
Autor: Christopher J. Ehrhardt, Patricia A. Holden, Michael G. LaMontagne, Rachel M. Haymon
Publikováno v: Environmental Microbiology. 9:900-912
Little is known about the fluids or the microbial communities present within potentially vast hydrothermal reservoirs contained in still-hot volcanic ocean crust beneath the flanks of the mid-ocean ridge. During Alvin dives in 2002, organic material

Fine-scale segmentation of volcanic/hydrothermal systems along fast-spreading ridge crests
Autor: Scott M. White, Rachel M. Haymon
Publikováno v: Earth and Planetary Science Letters. 226:367-382
Fine-scale (3rd and 4th order) segments of the mid-ocean ridge (MOR) are morphologically defined units of crustal accretion with enigmatic origins. At fast-spreading centers, 3rd order segments are bounded by discontinuities in the structure of the a

EARLY JURASSIC HYDROTHERMAL VENT COMMUNITY FROM THE FRANCISCAN COMPLEX, CALIFORNIA
Autor: Taniel Danelian, Rachel M. Haymon, Richard Herrington, Crispin T. S. Little
Publikováno v: Journal of Paleontology. 78:542-559
The Figueroa sulfide deposit located in Franciscan Complex rocks in the San Rafael Mountains, California, contains the only known Jurassic hydrothermal vent community. Based on radiolarian biostratigraphy it is Pliensbachian (early Jurassic) in age.

Time-series temperature measurements at high-temperature hydrothermal vents, East Pacific Rise 9°49′–51′N: evidence for monitoring a crustal cracking event
Autor: D. J. Fornari, A.M. Bray, Tracy K.P. Gregg, Michael R. Perfit, Marvin D. Lilley, Timothy M. Shank, K. L. Von Damm, Rachel M. Haymon, G Levai, Richard A. Lutz
Publikováno v: Earth and Planetary Science Letters. 160:419-431
Temperature measurements of hydrothermal vent fluids provide an important indicator of the physical and chemical state of mid-ocean ridge crest hydrothermal and magmatic systems. Changes in vent fluid temperature and chemistry can have dramatic effec

Axial summit trough of the East Pacific Rice 9°-10°N: Geological characteristics and evolution of the axial zone on fast spreading mid-ocean ridge
Autor: Michael R. Perfit, Margo H. Edwards, Rachel M. Haymon, Daniel J. Fornari, Tracy K. P. Gregg
Publikováno v: Journal of Geophysical Research: Solid Earth. 103:9827-9855
The nature and morphological characteristics of axial summit troughs on fast (∼90–130 mm/yr−1 full spreading rate) and superfast spreading (>130 mm/yr−1) mid-ocean ridge crests reflect the time-integrated effects of long-term magmatic cycles,
