▪ Abstract The recent recognition of a potentially vast, unexplored hot microbial biosphere
associated with active volcanism along the global mid-ocean ridge network has …

High-resolution images covering large areas of the seafloor reveal numerous discontinuities
along the mid-ocean ridge. These discontinuities occur at a range of scales (10–1,000 km) …

Convective circulation of seawater through oceanic crust at mid-ocean ridges (MOR) and on
ridge flanks has wide-ranging effects on heat transport, the chemical and isotopic …

The phenomenon of hydrothermal venting is a product of the deep-earth processes that
drive plate tectonics and the genesis of ocean crust at spreading centres. Trapped sea water …

Among the various university courses I took for my geoscience degree, volcanology and
structural geology motivated me by far the most. Volcanoes and deformed rocks are indeed …

In April, 1991, we witnessed from the submersible Alvin a suite of previously undocumented
seafloor phenomena accompanying an in-progress eruption of the mid-ocean ridge on the …

We analyze four expanded spread profiles acquired at distances of 0, 2.1, 3.1, and 10 km (0–
0.2 my) from the axis of the East Pacific Rise between 9° and 10° N. Velocity‐depth models …

The mid-ocean ridge (MOR) is the largest, most continuous volcanic system on Earth, yet we
have directly observed, mapped or sampled less than one percent of its total surface area …

Using the near-bottom ARGO imaging system, we visually and acoustically surveyed the
narrow (< 200 m wide) axial zone of the fast-spreading East Pacific Rise (EPR) along 83 km …

Crystalline basalt was reacted with a Na—Ca—K—Cl fluid of seawater chlorinity at 400, 350
and 300° C, 400 bar and a fluid/rock mass ratio of 1, to assess the effect of temperature on …
