Distribution of Turbidity in Australian Tropical Waters
2006
Mulhearn, P. J.
Data on underwater visibility in tropical Australian waters, in the form of Secchi disc depths and light attenuation coefficients have been collected and are presented in the form of maps with Secchi depths grouped in the ranges: less than 5 m, 5 m to 10 m, and greater than 10 m. As one would expect there is a general trend for water turbidity to decrease (or Secchi depth to increase) with depth, and for turbidity to be high in areas with a large tidal range. It can be seen, from the maps, that high turbidity would not infrequently limit diver and remotely operated vehicle operations along Australia's northern coastal shipping routes and in major port approaches.
