Wave rider data from 2 Cleveland Bay sites - 1993

Brief description

This is data collected during dredging by the Townsville Port Authority in Cleveland Bay in 1993. Data are divided into a number of main groups: Wind, tide gauge, wave rider, S4, sediment traps, water samples and nephelometers. Unique site numbers were assigned within Cleveland Bay at which data were collected. Some of these sites were named, and others were unnamed.

Statement: Wave ride data were collected at two sites. a) Dump site DUMPSITE.W b) Cape Cleveland CAPECLEV.W Data are stored in one file for each site. The structure of these files is illustrated below. Column 1 contains the date and time of a measurement as a 14 digit numeric string. Column 2 represents the same date and time, but as a decimal day number, where 1.00000 represents midnight of 1 January 1993. Column 3 represents the RMS wind wave height in m. Column 4 represents the significant wind wave height in m. Column 5 represents the RMS swell height in m. Column 6 represents the significant swell height in m. Column 8 represents the wind wave peak period. Column 9 represents the swell peak period. A several points in the file "-999999" appears in all nine columns and represents the end of a data set download. Each `break' is followed by the file header. This allows individual data sets to be easily identified. ------------------------------------------------------------------------- YYYYMMDDhhmmss t Hw Hws Hs Hss Twd Tw Ts ------------------------------------------------------------------------- 19930105180000 5.75000 0.126 0.355 0.043 0.121 2.439 2.479 10.201 19930105190000 5.79167 0.131 0.370 0.049 0.139 2.703 2.625 10.034 19930105200000 5.83333 0.130 0.367 0.054 0.152 2.778 2.737 9.952 19930105210000 5.87500 0.133 0.375 0.050 0.141 2.941 2.779 10.356 19930105220000 5.91667 0.136 0.386 0.045 0.127 3.226 2.890 10.367 .................................................................. 19930131220000 31.91667 0.292 0.825 0.089 0.251 5.556 3.677 9.366 19930131230000 31.95833 0.294 0.831 0.069 0.196 5.000 3.813 8.371 -999999 -999999 -999999 -999999 -999999 -999999 -999999 -999999 -999999 ------------------------------------------------------------------------- YYYYMMDDhhmmss t Hw Hws Hs Hss Twd Tw Ts ------------------------------------------------------------------------- 19930201000000 32.00000 0.321 0.907 0.071 0.201 5.556 3.767 8.481 19930201010000 32.04167 0.306 0.865 0.084 0.237 5.882 4.057 8.218 19930201020000 32.08333 0.316 0.895 0.088 0.248 5.000 4.068 8.355 ..................................................................
