Abstract:

Sediment texture and composition data were generated for selected core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to base of cores. Sediment texture values are expressed as % Gravel, % Sand, % Silt and % Clay as calculated by dry weight (g). % Mud can be calculated by combining % Silt and % Clay. Sediment composition is expressed as % carbonate content measured by acid leaching. This dataset supports the publication: Larson, R. A., Brooks, G. R., Schwing, P. T., Holmes, C. W., Carter, S.
