Baseline Surveys and EIAs

Marine Solutions has the in-house expertise to design and implement quality baseline surveys and Environmental Impact Assessments (EIAs) for a wide variety of projects. Our team’s extensive knowledge of marine ecology and coastal engineering enables us to evaluate anthropogenic impacts on the surrounding environment using a variety of techniques, including characterisation of habitat, biological communities and sediments, and quantification of water quality parameters through space and time. We have a thorough understanding of legislative requirements surrounding coastal construction works in Tasmania and further afield. In the past, we have conducted baseline surveys and EIAs for marina redevelopments, jetty constructions, effluent outfalls, underwater pipeline constructions and aquaculture leases.

Ecological Assessments

Our project team is experienced in assessing benthic flora and fauna, with the relevant techniques varying to reflect different substrate types. Standard techniques include infauna grabs, quadrat and transect surveys, towed and diver video, photo quadrats, and diver surveys for mobile invertebrates, fish, algae and sessile invertebrate communities. Usually a combination of these and similar techniques are utilised to characterise the marine community and also survey for threatened and protected species. Introduced species and sensitive habitats are also identified through this process. Within our team is specific expert knowledge of macroalgae, reef fish, coral and other benthic invertebrates’ identification.

Marine Solutions has designed and conducted numerous monitoring programs utilising benthic infauna as an indicator of impact. Notably among these was a three year study into impact from the Coffs Harbour deep sea release, and other ongoing studies in southern Tasmania monitoring impact of effluent outfalls. Marine Solutions has also conducted numerous finfish, algae, invertebrate and coral baseline surveys and monitoring in the past.

Video and ROV Surveys

The project team has extensive experience in underwater videography and interpretation of qualitative results. Video is taken with a state of the art full HD Sony NEX 5 camera housed in an Aquapazza underwater housing, along with over 1000W underwater video lights resulting in high quality clear footage. Video footage is reviewed by marine scientists who are experienced in determining habitat structure, community type and species composition from video and still photos. Detailed image analysis for community structure can also be conducted if required. In addition we have towed video capability with GPS overlay and speed/direction stamp should this be a more suitable method of collecting imagery. Marine Solutions also has access to, and experience operating, a powerful ROV with dual lights, USBL positioning system, grabber arm and dual cameras suitable for working in deeper environments. This system is comfortably housed on our larger research vessel, providing a safe and efficient operational platform. Still photography is taken by a 14MP DSLR in a housing with external lighting, providing high resolution images, even in challenging environmental conditions. Marine solutions also employs the use of contemporary aerial photography to help inform surveying and results.

Water Quality Monitoring

Marine Solutions uses a YSI 6920 V2 Multi-parameter Water Quality Sonde for in situ water quality measurements, which include, but are not limited to, temperature, depth, conductivity, salinity, turbidity, dissolved oxygen and chlorophyll.  We have the means to conduct deployments of the Sonde for continuous data recording over extended time periods, depending on the requirements of the given project.  We are also experienced with the deployment and management of Acoustic Doppler Current Profilers (ADCP) and a wide range of other data loggers including Conductivity Temperature Depth (CTD) loggers. This includes calibration, field operation, data management and reporting.  The sampling, techniques and constraints of water sampling in the southern regions of Tasmania are all well known to Marine Solutions, and we have strong relationships with support networks to ensure samples are handled and stored appropriately and then assessed in a timely manner.

Working closely with the Tasmanian aquaculture industry, Marine Solutions conducts regular water quality monitoring for the Tasmanian Shellfish Quality Assurance Program (TSQAP) in the southern Tasmanian region, and TasWater throughout Tasmania including the Pieman River in the state’s west and the D’Entrecasteaux Channel. We also conducted the environmental assessments for Spring Bay Seafoods, which resulted in them gaining international aquaculture sustainability accreditation through Friend of the Sea.  We are one of only a few organisations that has been granted approval to sample treated abalone live-holding discharge water from processors for laboratory testing in the interests of biosecurity (granted as of mid-2013).  In addition, Marine Solutions conducts a large amount of water quality monitoring for Sorell, Kingborough and Huon Valley Councils in relation to their effluent outfalls.
