[{"name":"oden-ao-2016-bathymetry-1","title":"High-resolution bathymetry data from the Arctic Ocean 2016 expedition","summary":"Multibeam bathymetry from areas in the Arctic Ocean, mainly in the Amundsen Basin and in areas around the underwater mountain ranges Lomonosov Ridge and Alpha Ridge.\r\n\r\nHigh-resolution bathymetry data are commonly used to study, for example, general seafloor geology, glacial morphology, bottom habitats, and bottom current activities. The data were collected from Swedish icebreaker Oden during the Arctic Ocean 2016 (AO16) expedition.\r\n\r\nThe bathymetry is acquired with a multibeam echo-sounder. The data are provided in the form of a compiled Digital Terrain Model with a grid cell size of 100 m. The processing of the raw data was carried out using the Qimera software by QPS.","citations":"Jakobsson M, Mayer LA, Bringensparr C, Castro CF, Mohammad R, Johnson P, Ketter T, Accettella D, Amblas D, An L, Arndt JE, Canals M, Casamor JL, Chauch\u00e9 N, Coakley B, Danielson S, Demarte M, Dickson M-L, Dorschel B, Dowdeswell JA, Dreutter S, Fremand AC, Gallant D, Hall JK, Hehemann L, Hodnesdal H, Hong J, Ivaldi R, Kane E, Klaucke I, Krawczyk DW, Kristoffersen Y, Kuipers BR, Millan R, Masetti G, Morlighem M, Noormets R, Prescott MM, Rebesco M, Rignot E, Semiletov I, Tate AJ, Travaglini P, Velicogna I, Weatherall P, Weinrebe W, Willis JK, Wood M, Zarayskaya Y, Zhang T, Zimmermann M, Zinglersen KB, (2020) The International Bathymetric Chart of the Arctic Ocean Version 4.0.

A Kongsberg EM122 1\u00b0\u2060\u200a\u00d7\u200a1\u00b0\u2060, 12 kHz, multibeam echo-sounder was hull-mounted in IB Oden. Position, heading and attitude data were received from a Kongsberg-Seatex Seapath 320 navigation unit (GPS and GLONASS) with attached MRU5 motion sensor. The exact speed of sound at the multibeam transducers was provided by a Valeport Mini SVS\/T sound speed and temperature sensor mounted in the sea-chest in Oden\u2019s hull, close to the multibeam transducer arrays. This was interfaced with the multibeam system directly. In addition, sound speed profiles for the entire water column were provided by CTD (Conductivity, Temperature, Depth) stations as well as XBT (Expendable Bathy Thermograph) probes.","category":"Marine","subcategory":"Bathymetry","keywords":"Geophysics; Arctic Ocean; Bathymetry; Seafloor morphology; Multibeam; AO16 expedition; Icebreaker Oden","scientist":"Lara F.
