[{"name":"oden-lomrog-2007-expedition-1","title":"Data from expedition LOMROG, Lomonosov Ridge, Arctic Ocean, 2007","summary":"The LOMROG (Lomonosov Ridge off Greenland) 2007 expedition was carried out during summer of 2007. The expedition worked in the central Arctic Ocean over sections of the southern Lomonosov Ridge off Northern Greenland, the Morris Jesup Rise and Yermak Plateu.\r\n\r\nWith the Swedish icebreaker Oden serving as the research platform, a range of scientific investigations were made. The main scientific goal was to map and core the southern Lomonosov Ridge off Greenland and decipher the current flow across the ridge, specifically the pathway of intermediate Atlantic water. Data provided in the database here comprise processed multibeam bathymetry.\r\n\r\nThe expedition started in Troms\u00f8, Norway, August 12 and ended in Longyearbyen, Svalbard, September 17, 2007.","citations":"\n  Jakobsson, M., Marcussen, C., and LOMROG Scientific Party, 2008, Lomonosov Ridge Off Greenland 2007 (LOMROG) - Cruise Report, 122 pp, Special Publication of Geological Survey of Denmark and Greenland, Copenhagen, Denmark.\n\n  Cronin, T.M., Keller, K.J., Farmer, J.R., Schaller, M.F., O'Regan, M., Poirier, R., Coxall, H., Dwyer, G.S., Bauch, H., Kindstedt, I.G., Jakobsson, M., Marzen, R. and Santin, E., 2019, Interglacial Paleoclimate in the Arctic.
