Event(s):
302-CompSite * Latitude: 87.890000 * Longitude: 137.650000 * Elevation: -1251.0 m * Campaign: Exp302 (Arctic Coring Expedition, ACEX) * Basis: CCGS Captain Molly Kool (Vidar Viking) * Method/Device: Composite Core (COMPCORE) * Comment: Virtual core composed of spliced cores from Holes M0002A, M0003A, M0004A and M0004C. Virtual position and water depth is calculated as the mean of all Exp302 sites.
Comment:
The location for the northern Canadian Islands is represented by the island closest to the ACEX core site, Ellesmere Island. Ellef Ringnes Island could also be used for this source area. All distances are straight line, direct to ACEX core site at 15 Ma and today.
