摘要

A multinational team of 36 researchers set sail on the Norwegian icebreaker Kronprins Haakon on September 19, 2019, from Svalbard, Norway, as part of the Hot Vents in an Ice-Covered Ocean (HACON) expedition to investigate biogeographical connections and biogeochemical interactions in this remote ocean.Deploying the hybrid ROV/AUV Nereid Under Ice (NUI) developed by Woods Hole Oceanographic Institution (Figure 1), the scientists wanted to investigate competing hypotheses concerning the genetics of hydrothermal vent fauna at the Arctic Ocean's Gakkel Ridge. Would the fauna show genetic similarities to vent fauna in the Norwegian-Greenland Sea or to chemosynthetic fauna from the far side of the Arctic near the Aleutians, or were they entirely new species?
