Comment:

Nine samples from Heinrich events 8, 9, and 10 were obtained from cores HU91020-074 and HU204024-042 which are located some 1900 km south of Hudson Strait in the area of the Flemish Cap and Orphan Knoll. Samples were also processed on the < 45 µm fraction in order the assess the impact of foraminifera on the wt% of calcite. Mineral wt%s and source fractions from SedUnMix with and without calcite wt%.
