1. Title of Dataset: Rheological_data Data were collected in the Warsaw Univesity of Technology, Faculty of Chemistry 2. Folder List: The folder Rheological_data contains AS48 XG0.8.csv Data on rheological characteristics of xanthan gum (0.8 g/L) dispersed in artificial seawater with salt content of 48 g/L. Aritifial seawater was prepared according to: ASTM, 2003. Standard practice for the preparation of Substitute Ocean water. ASTM D, 1141-98, with salinity adjustment. 3. Methodological information: MCR 301 rheometer with coaxial cylinders measuring geometry (CC17-SN12952, 0.714 mm gap) featuring a built-in Peltier device for temperature control at 21 °C. Flow curves were measured in the controlled shear rate (CSR) mode. 4. Data-specific information: *.csv files contain the following variables: - flow_curves: variables stored in six columns: shear rate [1/s], shear stress [Pa], viscosity [Pa s], speed [1/min], time [s], torque [µN m].
