Feeding Ecology of Coryphaenoides rupestris from the Mid-Atlantic Ridge

The Macrourid fish roundnose grenadier, Coryphaenoides rupestris, is one of the most common benthopelagic fishes on the northern mid-Atlantic Ridge. The ecology of the species is comparatively well studied in continental slope waters of the North Atlantic, but not on the mid-Atlantic Ridge, which is a central mid-ocean area of its distribution. In total, 166 specimens from the RV G.O. Sars crui...

Reverse Tectonic and Structural Analysis of North Tehran Fault hanging Wall Area

Introduction:    The study area has various types of geological structures, especially various types of fractures and folds. Evidence indicates that Structures with specific mechanisms in this area have been affected by Compressional - Tensile tensions.   Materials and methods:   To determine the direction of stress in the fault zone north of Tehran, from various tectonic evidences i...

Long-range backscatter from the Mid-Atlantic Ridge

Acoustic backscatter eturns measured with a vertical source and horizontal receiving array are beamformed and charted to respective scattering sites on the western flank of the Mid-Atlantic Ridge (MAR). Well-defined patterns of high-level backscatter esembling bottom morphology occur within the direct path and at convergence zone ranges. Measured backscatter is compared with modeled two-way tra...

A hydrous melting and fractionation model for mid-ocean ridge basalts: Application to the Mid-Atlantic Ridge near the Azores

[1] The major element, trace element, and isotopic composition of mid-ocean ridge basalt glasses affected by the Azores hotspot are strongly correlated with H2O content of the glass. Distinguishing the relative importance of source chemistry and potential temperature in ridge-hotspot interaction therefore requires a comprehensive model that accounts for the effect of H2O in the source on meltin...
