AMA Services
Australasian Marine Associates leads and contributes to multi-disciplinary teams, to help guide engineering project design and maximise environmental outcomes. We have specialist knowledge of marine ecology, ecosystem and coastal processes functioning, physical–chemical characteristics, impact assessment, risk mitigation and marine environmental approvals.
Marine Environmental Studies
Our team have conducted numerous marine investigations for clients including habitat mapping and bathymetric surveys, seagrass, infauna and sediment contamination. Our team also boasts experienced statistical analysis practitioners.
- Tropical, sub-tropical and temperate reef ecology
- Monitoring of suspended solids and turbidity and modelling of sediment transport processes
- Monitoring and modelling of metocean conditions, including drogue and tracer validation studies
- Estuarine gill netting, bat trapping and seine netting
- Investigations of incident light levels and sedimentation
- Soft sediment community studies including infauna and epifauna investigations, surveys of seagrass meadows and low profile reef
- Intertidal surveys, including mangrove and saltmarsh studies
- Fish surveys, including baited remote underwater video
- Marine mammal observations and other charismatic megafauna studies
- Bathymetry surveys and habitat mapping, including drop camera and towed video
Water, Sediment and Metocean Investigations
Our project team has previously undertaken sediment geochemistry and characterisation studies for a range of projects. Our team has developed survey and monitoring techniques for both mobile water quality monitoring, as well as fixed site instrumentation.
- Mobile water column profiling and water quality sampling
- Fixed site water quality monitoring, using buoy and mooring systems and where applicable telemetry for gathering data in real time
- Multiparameter systems including CTD, AWAC, ADCP, Wave rider and tide gauge systems
- Sediment sampling using sediment traps, diver coring, piston samplers, grab samplers and drop corers
Marine Infrastructure and Dredging
AMA personnel have executed a large range of dredging and port infrastructure related works including Wharf and Barge Ramp Construction, Geotechnical, Geophysical and Geochemical Investigations, Maintenance Dredging, Diver Based Piston Coring, Artificial Reef Feasibility, Design and Installation and Vibrocore Sampling and Analysis Programs. Our project team has also previously managed some of the largest dredging projects on the east coast of Australia.
- Vibracoring investigations for characterising unconsolidated sediments
- Piston coring investigations, including boat-based surveys using hand held piston cores in up to 10m water depth or diver-based coring systems
- Borehole drilling programs, using PQ3 or HQ3 drilling equipment deployed from truck-mounted or tracked drill rigs atop of our alliance partner's Jack-Up Barge or Spud Barges
- A consolidated approach to geotechnical, geological, geochemical and geophysical investigations for informing on marine infrastructure design
- Dredge site superintendancy and dredging services including diver assisted dredging, use of small mini dredgers for marina maintenance as well as large cutter suction dredgers for maintenance and capital works programs
- Maritime infrastructure maintenance including underwater debris clearance, pile, wharf and concrete restoration works
- Dredge Management Plans and dredging disposal strategies for both onshore (beach renourishment and land reclamation) and offshore disposal
- Sound understanding of the biology and environmental processes, alongside the design and fabrication works as well as the methods of installation for artificial reefs
