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:
Depth is given in meter composite depth (mcd) ! Neogene: 198.7 m/(18.2-2.2) Ma; total time interval minus 2.2 Ma long hiatus. Average sedimentation rate: 12.4 m/MA; Paleogene: (404.8-198.7) m/(56.2-44.4) Ma. Average sedimentation
