Objective | The MD 142/ALIENOR 2 survey(A LIbon-El Ferrol cruise. A support for North Oriental Atlantic Research) includes the PRIMAROSA 3 and SEDICAR 4 programs.The core sampling cruise's aim is to discover the response of a complete sedimentary system, that of the Channel, to the high climatic variability of the terminal Quaternary period. The objectives consisted in: - studying sediment transfers from the shelf edge towards deep systems by characterizing the various sedimentary figures (interfluve, channels/levees) and by distinguishing between the different input sources (glacial from the British Isles, periglacial from the English Channel or Loire river systems). - reproduce the paleoenvironmental conditions of the Bay of Biscay and in particular, try to track back to a period whose environmental conditions are closer to the current ones, ie about 400,000 years ago. The related programs are Ifremer's margin program, Image, GDR Marge. |
