Bulk density/porewater data from sediment cores collected onboard R/V Weatherbird II cruises WB-0815 and WB-0915 in the Gulf of Mexico from 2015-08-16 to 2015-10-01

This dataset reports measurement of sediment sample wet weight (g) and dry weight (g) for core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to the base of cores. Bulk density is the dry weight per sampling volume expressed as g/cm3. Dataset also reports percent porewater. The sediment cores were collected onboard the R/V Weatherbird II cruises WB-0815 and WB-0915 in the Gulf of Mexico from 2015-08-16 to 2015-10-01. Chief Scientist for these cruises was Dr. Steve Murawski and the objective was to create Gulf-wide baselines for sediment and fish.

本数据集记录了表层单元（surficial unit）岩芯子样品的相关测定数据：其中表层单元的岩芯子样品以2毫米采样间隔采集沉积物样品的湿重（单位：克）与干重（单位：克）；岩芯其余部分直至底部则以5毫米采样分辨率间隔完成测定。容重（bulk density）指单位采样体积的干重，单位为克每立方厘米（g/cm³）。本数据集同时记录了孔隙水占比。本次沉积物岩芯采集工作依托2015年8月16日至10月1日在墨西哥湾开展的“气象鸟二号”（R/V Weatherbird II）考察船WB-0815与WB-0915航次完成，该航次首席科学家为史蒂夫·穆拉夫斯基（Steve Murawski）博士，研究目标为建立墨西哥湾全域沉积物与鱼类的基准基线。
