Comment:

Samples from six piston cores from cruise HU90023-030, -031, -034, -045, 099 and 101 (MacLean, 1991) were processed to provide information of the source(s) of Hudson Strait Heinrich sediments in the Labrador Sea. The cores are located in terms of latitude, longitude, water depth, and the regional name for each site (MacLean, 2001a). Radiocarbon dates on the cores are listed in MacLean (ed) (2001) and in (Manley and Jennings, 1996).
