Smectite composition as a tracer of deep circulation: the case of the Northern North Atlantic
peer reviewed The link between smectite composition in sediments from the northern North Atlantic and Labrador Sea, and deep circulation is being further investigated through detailed studies of the X-ray pattern of smectites and cation saturations. This allows clear distinction of dominant terrigen...
