Sediment trap data sets for sites around Cleveland Bay - 1993

Researchers: Ridd, Peter, Professor (Principal investigator)

Brief description This metadata record covers a subset of the 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. The data are grouped according to collection method and sampling location. See the metadata record title for collection method and geographic extent for the sampling location. Unique site numbers were assigned within Cleveland Bay at which data were collected. Some of these sites were named, and others were unnamed.

Lineage Maintenance and Update Frequency: notPlanned

Lineage Statement: Sediment traps were installed at a number of locations, in three groupings. The groupings represent the data collection strategy, rather than any pre-determined oceanographic grouping. a) Cleveland Bay CLEVELAB.ST b) Geoffrey Bay GEOFFREY.ST c) Rattlesnake Island RATTLESN.ST Data are stored with several sites per file. The structure of these files is illustrated below. Column 1 contains the date and time of the start 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 sedimentation rate in mg/cm^2/day. Column 4 represents the number of days over which the sediment was collected. Column 5 represents the site number. ----------------------------------------------- YYYYMMDDhhmmss t mg/cm^2/day days Site ----------------------------------------------- 19930120000000 20.00000 79.24 16.0 1 19930120000000 20.00000 72.18 15.8 2 19930120000000 20.00000 24.93 18.0 7 19930120000000 20.00000 68.44 18.0 6 19930120000000 20.00000 28.30 20.5 4 19930120000000 20.00000 54.03 20.5 3 19930120000000 20.00000 62.29 17.0 5 19930120000000 20.00000 17.09 15.8 12 19930120000000 20.00000 26.58 18.0 13 ----------------------------------------------- YYYYMMDDhhmmss t mg/cm^2/day days Site ----------------------------------------------- 19930202000000 33.00000 15.33 11.0 1 19930202000000 33.00000 14.86 11.0 2 19930202000000 33.00000 12.12 14.0 7 19930202000000 33.00000 27.64 13.8 6 19930202000000 33.00000 36.62 11.0 4 19930202000000 33.00000 16.54 11.0 3 19930202000000 33.00000 39.50 15.0 5 19930202000000 33.00000 24.64 14.0 13 19930202000000 33.00000 5.72 33.0 14 ........................................
