Sediment texture and composition of sediment cores collected during R/V Weatherbird II cruises in the northern Gulf of Mexico from 2010-11-18 to 2016-09-09

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. R., & Hollander, D. J. (2018). High-resolution investigation of event driven sedimentation: Northeastern Gulf of Mexico. Anthropocene, 24, 40–50. doi:10.1016/j.ancene.2018.11.002本数据集生成了经筛选的岩芯子样本的沉积物粒度与组成数据：针对“表层单元（surficial unit）”采用2mm的采样间距，针对岩芯全段则采用5mm的采样分辨率。沉积物粒度参数以干重（g）计算得到的砾石（Gravel）、砂粒（Sand）、粉粒（Silt）和黏粒（Clay）百分含量表示；粉粒与黏粒的百分含量之和可换算为泥质（Mud）百分含量。沉积物组成以酸浸法（acid leaching）测得的碳酸盐百分含量表征。本数据集支撑以下发表文献：Larson, R.
