 A Chem5 Dataset is a specialized [[:geoscene3d:project_content:datasets:tabular_dataset|]] containing columnar water chemistry data. A Chem5 Dataset may contain analysis of a single chemical parameter in multiple samples over a period of time. Each row in the dataset represents one analysis in time for one parameter from one screen. A Chem5 Dataset is a specialized [[:geoscene3d:project_content:datasets:tabular_dataset|]] containing columnar water chemistry data.
