Rare earth element (REE) and yttrium (Y) concentrations were measured in fluids collected
from deep-sea hydrothermal systems including the Mid-Atlantic Ridge (MAR), ie, Menez …

During the DIVA 1 cruise in May 1994, a series of 19 dives was conducted using the French
submersible Nautile at the topographic highs of three volcanic segments centered at 37° …

Recent seismic observations and new crustal thermal models suggest that near-axis (±1 km
from the spreading axis) hydrothermal cooling increases linearly with increasing spreading …

During the Naudur cruise in December 1993, 23 dives using the French submersible Nautile
were conducted on the axis of the East Pacific Rise between 17° and 19° S where the …

Simultaneous acoustic imaging of the seafloor and detection of particle-rich plumes in the
overlying water column have been used to identify and determine the tectonic setting of high …

Slow spreading mid-ocean ridges like the Mid-Atlantic Ridge host a remarkable diversity of
hydrothermal systems including vent systems located on the neovolcanic axis, large axial …

We have investigated the relations between volcanic, tectonic, and hydrothermal activity on
Lucky Strike Seamount (37° 17′ N, Mid‐Atlantic Ridge) using a nested survey strategy …

High-resolution, side-looking sonar data collected near the seafloor (∼ 100 m altitude)
provide important structural and topographic information for defining the geological history …

The crust at mid-ocean ridges is formed through a combination of magmatic and tectonic
processes. Along slow-spreading ridges, magmatism is inferred to be discontinuous and …

Systematic hydrothermal exploration and multi-beam bathymetry mapping have been
conducted along a 220-km-long section of the Southern Mid-Atlantic Ridge (SMAR) from 12° …
