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...
متن کاملLong-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...
متن کاملDominance of one bacterial phylotype at a Mid-Atlantic Ridge
Microbial community structure in natural environments has remained largely unexplored yet is generally considered to be complex. It is shown here that in a Mid-Atlantic Ridge hydrothermal vent habitat, where food webs depend on prokaryotic primary production, the surface microbial community consists largely of only one bacterial phylogenetic type (phylotype) as indicated by the dominance ofa si...
متن کاملA 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...
متن کاملCopepod distribution and production in a Mid-Atlantic Ridge archipelago.
The Saint Peter and Saint Paul Archipelago (SPSPA) are located close to the Equator in the Atlantic Ocean. The aim of this study was to assess the spatial variations in the copepod community abundance, and the biomass and production patterns of the three most abundant calanoid species in the SPSPA. Plankton samples were collected with a 300 µm mesh size net along four transects (north, east, so...
