Nephelometer data sets for 14 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 Statement: Nephelometer data were collected at 14 sites. a) Seagrass site (south) SEAGRASS.N b) Seagrass site (centre) SEAGRASC.N c) Dredge area (west) DREDGEW.N d) Dredge area (east) DREDGEE.N e) Dump site (north) DUMPN.N f) Dump site (south) DUMPS.N g) Dump site (west) DUMPW.N h) Arthur Bay (edge of reef, top) ARTHURG.N i) Arthur Bay (deep, outside reef) ARTHURD.N j) Geoffrey Bay (edge of reef, top) GEOFFREG.N k) Geoffrey Bay (deep, outside reef) GEOFFRED.N l) Horseshoe Bay HORSESHO.N m) Middle Reef MIDDLERE.N n) Rattlesnake Island RATTLESN.N 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 suspended sediment concentration (SSC) in mg/l. A several points in the file "-999999" appears in all three 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 mg/l ------------------------------- 19921230095000 -0.59028 1.46 19921230095500 -0.58681 1.46 19921230100000 -0.58333 1.46 19921230100500 -0.57986 1.46 19921230101000 -0.57639 1.46 ......................... 19930117083500 17.35764 1.23 19930117084000 17.36111 1.23 -999999 -999999 -999999 ------------------------------- YYYYMMDDhhmmss t mg/l ------------------------------- 19930205061704 36.26185 10.91 19930205062204 36.26532 9.95 19930205062704 36.26880 9.31
