Spectrums.zip contains two types of files. The .spt file contain the raw data from the BunkerHill buoy outside Sylt. The fourth entry is the relative PSD of the day, and in the main body of the file the coloumns represent: frequency [Hz], PSD [m^2/Hz], Main direction, directional spreading, Skew, Kurt. The .txt files contains the 2D SWAN spectrums used in the paper. For further description look to: https://swanmodel.sourceforge.io/online_doc/swanuse/node50.html. radsAndCircs.txt contain data about the circulations calculated in the surf zone. Each row corresponds to one circulations, and the coloumns correspond to: Number, tide [m], spreadfactor, main direction [degr], x-location [m], y-location [m], \(\sigma [m], \Gamma_{max} [m^2/s]\). Then 100 radii and then the 100 corresponding circulations. Tracers.zip contain the 6 orange paths described in the paper. They contain lon/lat coordinates for the oranges sampled at 3Hz. BOSZ_outputs contains all the data from all the runs used in the paper. The .bosz files must be opened with the load_BZ_array.py script. Of interest of the paper are the longitudes and latitudes, X.bosz and Y.bosz; averaged U and V velocites, Ubartmp.bosz and Vbartmp.bosz. The files are stored as a MxN array, where each element correspond to the value of the variable on the calcualted grid. The Drifter.txt files contains all the data of the numerical drifters. They are built up as: time, xDrift1, yDrift1, xDrift2, yDrift2, xDrift3, yDrift3, ... For data about the bathymetry we refer to the LKN.SH.
