Amore 2001 has successfully investigated the gakkel ridge and arctic ocean in vicinity of its geological and geophysical nature, as well as the nature of sea ice and biology in this area. the preliminary onboard petrology and bathymetry results show that the mantle beneath the gakkel ridge with low temperature has only encountered very low degree partial melting during the spreading and there is no any direct relationship between the crust nature and the spreading rate along the gakkel ridge in any simple petrologic way. mantle temperature and fracture zone density also play a major role on the crust nature, besides spreading rate
