Indicator: CO-52 Evidence or examples of impacts of channel dredging for shipping on marine life
Data
No data found specific to channel dredging in Australia.
What the data mean
No data found.
Data Limitations
No data found.
Issues for which this is an indicator and why
Coasts and Oceans — Direct pressure of human activities on coasts and oceans - Direct pressure of shipping
Dredging of channels to provide access to ports and harbours for larger vessels involves removing part of the benthos. It is reasonable to assume that this removal could be disruptive to benthic species and interdependent organisms.
No indicator has been developed for measuring or assessing the extent of this pressure or its actual impact on marine organisms.
Other indicators for this issue:
- CO-27 Number, frequency, extent and volume of oil spills from all sources
- CO-32 Number of injuries to marine animals from marine debris
- CO-50 Number of collisions with marine animals
- CO-51 Quantity of sewerage and ballast water dumped by shipping
- CO-53 Evidence or examples of noise or visual disturbance of marine species by human activities
- CO-65 Correlation between various human activities and introduction of coastal and marine species
- CO-67 Progress of the Australian shipping fleet towards meeting the targets of the International Convention on the control of harmful anti-fouling systems on ships
- LD-40 Current research into pressures and contributions of naturalised introduced species
Biodiversity — Pressures on biodiversity - Pressures on marine biodiversity: pressures of shipping
Dredging of channels for shipping has the potential to place pressure on marine biodiversity. No indicator has been developed for measuring or assessing the extent of this pressure or its actual impact on marine organisms.
