Carbon and nitrogen data measured on water samples from the multiple unit large volume filtration system (MULVFS) during John P. Tully cruise IOS_96-18@en

For MULVFS data, the QMA filters were first sub-sampled with a punch, and a small section of known size was cut from each of the sub-samples.针对MULVFS数据集，首先对QMA滤波器（QMA filters）通过冲孔法完成下采样，随后从每个下采样得到的样本中截取一段尺寸已知的片段。
