Quantitative dispersion data, generated on a laboratory scale, using different experimental set-ups and approaches, in order to fill in different blanks in modelling the dispersion process. Main variables investigated are oil properties and dispersant concentration(/presence) in relation to; surface oil entrainment, oil droplet breakup and oil-sediment interaction.



Laboratory generated data, geographic and temporal extents are not relevant to this dataset

Supplemental Information

Laboratory data of natural and chemical dispersion of floating oil for model development. 1. Analyzed Pictures: a BMP file of every picture analyzed. Filenames are YYYYMMDD_##_[Close, chem_Close, chem_Total, Total]_#####.bmp 2. Blobanalyses: an output CSV for the BLOB analysis each test picture analyzed. Filenames are the same as for the Pictures. Area, Breadth, CoGX, CoGY, Eccentricity, EllipsFit, ExCircleR, FormFactor, Hu1, Hu2, Hu3, Hu4, Hu5, Hu6, Hu7, InCircleR, Length, LengthBreadthRatio, InCircleBreadthRatio, InCircleExCircleRatio, Class, Patch 3. Supplementary Pictures (fig6). Filenames are YYYYMMDD_[EmptyTank_Close, OilDisp_Close, Water_Close, Water_Total]_#####.bmp 4. Experiments list.csv (Layer Thickness and Oil Properties): The list of tests performed, with Date; TestName; Oil Type, Hoil =oil layer thickness (mm); Hplunge = Plunge height (cm); Dispersant to Oil Ratio; Estimated Actual oil layer thickness (um). 5. R.Output file.csv (Layer Thickness and Oil Properties): Combined results of Blobanalysis. X., Datummap,, Frame, Time..sec., Oil.Type, Hoil, Hplunge, Rep., Dispersant, cPx123, cPx4, cPx5, cPx6, cPx7, cPx8, cPx9, cPx10, cn (number of droplets in close up picture), cPx4F (oil in droplets with D=4pixels; Volume Fraction), cVol5F (oil in class 5 BLOB’s in the close up picture; Volume fraction), tVol5F (oil in class 5 BLOB’s in the close up picture; Volume fraction), cVol (Total volume of oil in the close up picture; px3), tVol (Total volume of oil in the close up picture; px3), cVolT (Total volume of oil in the test tank; ml) |The tests were performed using a plunging jet method with coupled camera system. A full description can be found in the paper named "Quantification of the effect of Oil Layer Thickness on Entrainment"(doi:10.1016/j.marpolbul.2015.04.015).||||
