1. Title of Dataset: Density_profiles Data were collected in the Laboratory of Hydrodynamic Micromodels, Institute of Geophysica, Polish Academy of Sciences Dataset contains density profiles profiles of water columns measured in each experimental set. DMA 4100 M (Anton Paar) densimeter was used to measure the density of solutions with an accuracy of 0.0001 g cm-3 in a controlled temperature with an accuracy of 0.03 ◦C. Details on each dataset is provided in README files in each subfolder: 2. Folder List: rho_depth_AS36_AS48 rho_depth_AS36_AS48XG08 3. Data specific information: Each folder contains two columns: 1st column is depth (m), second column is density (kg m-3).
