Several cores raised from the NW Atlantic, mostly by CSS-Hudson or
by the Marion Dufresne, have been analyzed at GEOTOP in past years. Most of these cores
were collected within the framework of two major projects:
i) from 1990 to 1993, through a special collaborative project of the National Science and
Engineering Research Council of Canada (NSERC) on the Labrador Sea (see Can. J. Earth Sci.
vol 31, n°1, 1994)
ii) since 1995, through a Canadian contribution to Images (International
Marine Global Change Study) through the Climate System, History and
Dynamics (CSHD)
project supported by NSERC and the Geological
Survey of Canada (GSC).
Micropaleontological, sedimentological and stable isotopes analyses have been performed at variable resolutions on most of these cores. Files containing data on stable isotope composition of planktonic foraminifers, 14-C ages, organic carbon, carbonate and coarse fraction contents of the sediment (whenever available) can be downloaded from this data base. Higher resolution analyses are occasionnally available. They can be obtained by request to the principal investigator (see references).
Data can be seen by clicking on any of the the coring sites illustrated in the map link below and can be downloaded by clicking the appropriate core from the data list. They can be downloaded as a tab-delimited text file(*.txt) or as a comma delimited text file (*.csv).
