Bulk density and porewater data collected onboard R/V Weatherbird II cruises WB-0813 and WB-1405 in the northern Gulf of Mexico from 2013-08-15 to 2013-09-27

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. The dataset also reports percent porewater. The sediment cores were collected onboard the R/V Weatherbird II cruises WB-0813 and WB-1405 in the northern Gulf of Mexico from 2013-08-15 to 2013-09-27. Chief scientists for these cruises were Dr. Steve Murawski and Dr. David Hollander for WB-0813, and Oscar Garcia for WB-1405. The objective of cruise WB-0813 was to create Gulf-wide baselines for sediment and fish and cruise WB-1405 was dedicated for benthic ecology.本数据集记录了表层单元（surficial unit）岩心副样以2mm采样间隔、岩心底部以5mm采样分辨率采集的沉积物样品湿重（g）与干重（g）。容重（bulk density）指单位采样体积的干重，单位为g/cm³。本数据集同时收录了孔隙水占比数据。沉积物岩心采集自2013年8月15日至2013年9月27日在墨西哥湾北部执行科考任务的“气象鸟二号”（R/V Weatherbird II）科考船，对应航次为WB-0813与WB-1405。其中WB-0813航次的首席科学家为史蒂夫·穆拉夫斯基（Steve Murawski）博士与戴维·霍兰德（David Hollander）博士，WB-1405航次的首席科学家为奥斯卡·加西亚（Oscar Garcia）。WB-0813航次的目标是建立墨西哥湾全域沉积物与鱼类的基准基线，而WB-1405航次则专门针对底栖生态学开展研究。
