Seamount Catalog
The Seamount Catalog is a digital archive for bathymetric seamount maps that can be viewed and downloaded in various formats. This catalog contains morphological data, sample information, related grid and multibeam data files, as well as user-contributed files that all can be downloaded. Currently this catalog contains more than 1,800 seamounts from all the oceans.

  • The Rurutu Hotspot RR1310 Expedition plans to dredge 20 seamounts in the Tuvalu-Samoa area of the western Pacific. We aim to address the hypothesis stating that the Rurutu hotspot in French Polynesia formed a long-lived seamount trail that extends at least into the Tuvalu area and contains a pronounced bend synchronous with the Hawaii-Emperor bend. The goals of the project will be accomplished by utilizing geochemical fingerprinting combined with absolute age dating. Visit the Expedition Website ...

  • Follow the third and final G-439 Expedition that uses the extreme environments of volcanoes in the McMurdo area as a model system to shed light on these questions on microbial life and life in extreme environments. G-439 will work below the sea-ice, in frozen lakes in the Dry Valleys and fumarolic ice caves on the ice-covered 14,000 feet tall Mt. Erebus volcano, the southernmost active volcano on Planet Earth. Follow this website read about the G-439 project. Visit the Expedition Website ...

  • Expedition MV1203 aims to dredge 40 seamounts along the southwest portion of the Walvis Ridge seamount trail. The Walvis Ridge begins on the African continent and extends to near the mid-Atlantic Ridge. The southwest half of the Walvis Ridge appears to bifurcate into two distinct physical and geochemical trends, the Tristan (northern) and Gough (southern) tracks. The data we collect will assist in improving absolute plate motion models for the African continent, and knowledge of the geochemical evolution of plumes and the regional tectonic setting of the surrounding area.

  • IODP Expedition 330 to the Louisville Seamount Trail will drill four underwater volcanoes off the NE coast of New Zealand. One hypothesis states that these volcanoes formed above a narrow plume of hot mantle rising from a position deep in the Earth's mantle. For decades scientists assumed these mantle plumes remain anchored there for tens of millions years, but there is mounting evidence that mantle plumes wander in a large-scale mantle wind. This expedition aims to establish how much mantle plumes may have moved over the last 80 million years and whether the Louisville hotspot moved coherently with the Hawaii hotspot.
