Multi-sensor core logger and laboratory analysis data collected from Marcus G. Langseth in the North Atlantic Ocean from 20230605 to 20230608 (NCEI Accession 0311989)

Multi-sensor core logger data and laboratory consolidation and grain size tests performed on jumbo piston core samples.

This dataset contains Geotek multi-sensor core logger (MSCL) data from cores collected on the R/V Marcus G. Langseth in June 2023 and processed geotechnical data for the collected samples. All laboratory tests were performed at The University of Texas at Austin. The data include results of constant rate-of-strain consolidation tests (compression index, swelling index, permeability, porosity) and grain size measurements (% sand, % silt, % clay, and grain size distribution quartiles).

巨型活塞岩芯样品的多传感器岩芯测井数据与室内固结、粒度测试数据集
本数据集涵盖2023年6月于‘马库斯·G·兰塞斯号’（R/V Marcus G. Langseth）科考船采集的岩芯的吉泰克（Geotek）多传感器岩芯测井仪（Multi-sensor Core Logger, MSCL）数据，以及经标准化处理的采集样品岩土工程数据。所有室内测试均于德克萨斯大学奥斯汀分校完成。本次测试数据包含等应变速率固结试验结果（压缩指数、膨胀指数、渗透系数、孔隙率）与粒度测试结果（砂粒、粉粒、黏粒百分含量及粒度分布四分位数）。
