Hydrobiology WA has recently acquired certification to dive in order to conduct monitoring studies for Rio Tinto.
Our Perth office has recently completed auditing and field assessments for their commercial diving to AS2299.1:2007 and Rio Tinto standards. The first diving operations for Rio Tinto were undertaken in May to retrieve and replace 30 loggers including turbidity, light (PAR) and temperature at their Cape Lambert port operations. We also collected sediment traps and water quality associated with their long term dredging monitoring.
Hydrobiology has conducted a wide range of programs for Rio Tinto at Cape Lambert over the previous 18 months including coral, macroalgae, mangrove, imposex, oyster biomonitoring, water and sediment quality studies associated with implementation of the port Marine Environmental Quality Management Plan (MEQMP). Other activities in the iron ore industry in Western Australia have included studies of ephemeral creeks and permanent pool hydrology, geomorphology, water quality and ecology for the in the eastern Pilbara and predicting pit lake water quality geochemical evolution at a proposed magnetite mine.
