Martin Jakobsson, Larry Mayer, Ryder 2019 Scientific Party Data from expedition Ryder, off North Greenland, 2019 Bolin Centre Database 2021 Datafile Marine Expedition Icebreaker Oden Arctic Ocean Bathymetry Multibeam Oceanography Meteorology Glaciology Earth science > Oceans Martin Jakobsson The main scientific goal was to increase our knowledge on the marine cryosphere and ecosystem of Northwest Greenland, specifically changes that have or may occur due to a warming of the climate. The marine cryosphere includes outlet glaciers extending into the ocean, sea ice, frozen gas hydrates and subsea permafrost. In addition, land research included collection of driftwood for paleoclimate studies, mapping of uplifted shorelines and collections of clam shells for dating to reconstruct sea-level history, and terrestrial ecology. The latter included sediment coring in lakes for ancient DNA research. Scientists from Sweden, USA, Canada and Denmark made up the scientific party of 39. The logistics of the expedition was financially supported by the Swedish Polar Research Secretariat, the Center for Coastal and Ocean Mapping, University of New Hampshire, and Stockholm University. The Nippon Foundation of Japan supported multibeam bathymetry to be collected during the transects from and back to Sweden. All multibeam bathymetry data are contributed to the Nippon Foundation — GEBCO — Seabed 2030 project. The US Arctic Research Commission facilitated support from NOAA with satellite imagery for ice recognizance during the expedition. ##### Participants ###### Co-chief scientists * Martin Jakobsson, Department of Geological Sciences, Stockholm University, Sweden * Larry Mayer, Center for Coastal and Ocean Mapping/Joint Hydrographic Center, University of New Hampshire, USA ###### Expedition work package leaders * Geophysical Mapping: Brian Calder (University of New Hampshire) * Remotely Operated Mapping: Sam Reed (University of New Hampshire), Kevin Jerram (University of New Hampshire) * Water Column Imaging: Christian Stranne (Stockholm University), Liz Weidner (Stockholm University/University of New Hampshire) * Sediment Coring/Processing: Matt O’Regan (Stockholm University), Carina Johansson (Stockholm University) * Physical Oceanography: Johan Nilsson (Stockholm University), Christian Stranne (Stockholm University) * Sediment and Water Chemistry: Volker Brüchert (Stockholm University), Adam Ulfsbo (University of Gothenburg) * Water Column Biology: Julek Chawarski (Memorial University) * Glaciology: Nina Kirchner (Stockholm University), Abhay Prakash (Stockholm University), Felicity Holmes (Stockholm University) * Trace Gas Biogeochemistry: Brett Thornton (Stockholm University) * Sea level history: Alan Mix (Oregon State University) * Paleoclimatology: Hans Linderholm (University of Gothenburg) * Terrestrial ecology, paleoecology, and archaeology: Love Dalén (Swedish Natural History Museum), Fredrik Dalerum (Stockholm University) ###### Scientific party * Lee-Gray Boze, USGS USA * Volker Brüchert, Stockholm University, Sweden * Brian Calder, University of New Hampshire, CCOM, USA * Christian Carøe, Copenhagen University, Denmark * Julek Chawarski, Memorial University, Canada * Tom Cronin, USGS, USA * Love Dalé, Swedish Natural History Museum, Sweden * Fredrik Dalerum, Stockholm University, Sweden * Björn Eriksson, Stockholm University, Sweden * John Farrell, US Arctic Research Commission, USA * Jonas Fredriksson, Stockholm University, Sweden * Laura Gemery, USGS, USA * Anna Glüder, Oregon State University, USA * Anders Götherström, Stockholm University, Sweden * Björn Gunnarson, Stockholm University, Sweden * Dan Hammarlund, Lund University, Sweden * Tamara Handl, Stockholm University, Sweden * Felicity Holmes, Stockholm University, Sweden * Martin Jakobsson, Stockholm University, Sweden * Kevin Jerram, University of New Hampshire, CCOM, USA * Carina Johansson, Stockholm University, Sweden * Markus Karasti, Stockholm University, Sweden * Hans Linderholm, University of Gothenburg, Sweden * Johannes Måsviken, Stockholm University, Sweden * Larry Mayer, University of New Hampshire, CCOM, USA * Alan Mix Geologist, Oregon State University, USA * Julia Muchowski, Stockholm University, Sweden * Johan Nilsson, Stockholm University, Sweden * Matt O’Regan, Stockholm University, Sweden * June Padman, Oregon State University, USA * Abhay Prakash, Stockholm University, Sweden * Sam Reed, University of New Hampshire, CCOM, USA * Brendan Reilly, Oregon State University, USA * Emelie Ståhl, Stockholm University, Sweden * Christian Stranne, Stockholm University, Sweden * Brett Thornton, Stockholm University, Sweden * Adam Ulfsbo, University of Gothenburg, Sweden * Elizabeth Weidner, University of New Hampshire, CCOM, USA * Gabriel West, Stockholm University, Sweden See more information at the [Swedish Polar Research Secretariat]( #### Version history ##### Version 2.0 A glacier calving front imagery and two marine chemistry datasets added. ##### Version 1.0 Initial release.
