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
對所取得資料的初步研究表明gakkel洋中脊之下的地幔僅經受了較低程度的部分熔融，具有較低的溫度。 gakkel洋中脊處的地殼性質和巖漿活動與擴張速率之間不存在任何直接的巖石學相關性，擴張而導致的巖石圈頂部的冷卻並不是決定洋脊處地殼性質的最重要因素。地幔溫度和斷裂帶的存在與否及其密度對地殼性質具有重要的影響意義。 -
