East Gakkel Ridge at 85°E

Tipo
Fisura volcánica
Altitud

Última erupción

Detailed bathymetry of the East Gakkel Ridge at 85°E in the Arctic Ocean. The inset map shows the location of the 85°E segment (yellow star) along the Gakkel Ridge (red line). The main panel shows illuminated color bathymetry (30-m grid spacing) of the 85°E segment acquired during the AGAVE expedition. The axial valley contains large numbers of distinctive, cratered volcanoes, including a cone on a fault terrace of the northern valley wall. Named features include two volcanic ridges in the center of the axial valley (Jessica’s Hill and Duque’s Hill), and three cratered volcanoes along a ridge-parallel fissure to the south (Oden, Thor, and Loke). The bathymetry data were plotted with Generic Mapping Tools.
