Working across the continuum of offshore marine, coastal, rivers and wetland environments in both temperate and tropical climates, BMT’s expert environmental scientists and ecologists understand that maintaining environmental quality requires an understanding of the species and habitats that are present but also the underlying physical and chemical ecosystem processes that drive and determine habitat suitability.
Our multidisciplinary approach across relevant scientific fields, benefits our clients and their projects by providing an integrated in-house capacity for assessing ecological, water and sediment quality issues in marine and aquatic environments.
From modelling environmental carrying capacity through to offering practical management tools, we provide aquaculture customers with end-to-end, integrated solutions. Whether mapping the sea floor or estimating the benthic footprint and nitrogen carrying capacity of the local marine environment, we have evolved services that are not only highly innovative: they are immediately practical and relevant. Our team, for example, has developed an environmental modelling package encompassing 3D-hydrodynamic, water quality, particle transport and sediment biogeochemical models (AquaDEEP). When coupled with relevant site-specific information, AquaDEEP allows us to predict the impact of sea-cage operations, sea-floor recovery timelines and optimise water quality conditions for enhanced production.
Our approach to aquaculture development encompasses three stages: mapping, modelling and management.
Mapping: Site selection is critical to sustainable aquaculture development. We use custom spatial modelling tools and GIS mapping technologies to determine the suitability, depth and habitat complexity of potential sites.
Modelling: BMT has invested heavily in the development of integrated modelling products for the aquaculture industry (AquaDEEP). AquaDEEP provides capacity to estimate the environmental footprint of farms based on local hydrodynamics, feed inputs, and relevant environmental cause-effect pathways. AquaDEEP is assisting a range of government and industry-based clients in Australia, Saudi Arabia and the United Arab Emirates with decisions regarding placement of infrastructure and the management of proposed operations.
Management: BMT is an industry leader in the development and application of environmental management frameworks for the aquaculture industry, from low-impact sea-ranching operations to major off-shore sea-cage developments.
Successful marine and aquatic management is underpinned by understanding of the extent, and sensitivity of local marine habitats. Our high quality marine habitat maps are produced by remote sensing specialists, in consultation with our team of benthic marine ecologists. Depending on the depth and clarity of the water, mapping is undertaken using imagery (aerial or satellite) or hydroacoustic data (sidescan or multibeam backscatter), together with groundtruthing utilising towed video, RoV mounted video, or spot dives).
BMT has the experience and resources to respond rapidly to emergency situations including ship groundings, and unplanned discharges. Our team of experts remain on standby for a range of maritime industry clients and have the skills and expertise to design monitoring programs and collect meaningful data, no matter the size of the emergency nor the remoteness of the impacted area.
Our experts understand the complexities of water quality and sediment dynamics and use their knowledge to help you develop effective strategies to identify, monitor, measure, manage and mitigate changes in the environment.
Our understanding of environmental quality guidelines, standards and trigger values support compliance and smarter decision making. This together with our ability to separate environmental impacts from background noises, allows us to develop programmes which balance sensitivity and cost, and which provide precise measurements of environmental stressors: toxicants (and toxicity), nutrients, organics, pesticides, herbicides, PFAS and hydrocarbons.
Our marine biologists and quantitative ecologists are experts in the design, implementation and interpretation of marine flora and fauna surveys and monitoring programmes. Our staff have years of industry experience, which translates to survey designs and monitoring programmes that are of the highest scientific quality and support regulatory approvals.
We offer the following marine flora and fauna survey design, implementation and analysis services:
Healthy catchments, watersheds and adjacent wetland and riparian vegetation areas are essential to healthy aquatic ecosystems.
For these critical environments, we offer the following flora and fauna survey design, implementation and assessment services:
We marry the needs of the regulator with the constraints of the customer to create data-driven programmes that support business or governmental objectives while protecting the environment for future generations. We are also experts in the design, execution and interpretation of biological surveys.
Our specialists have designed hundreds of monitoring programmes for a wide range of projects and customers, including:
A key element in the design of environmental monitoring programmes is determining thresholds, beyond which there is a risk of unacceptable environmental impact. Our expert knowledge and extensive experience means that we understand and identify environmental cause and effect pathways to help you set the right threshold.
Some examples of thresholds and associated sectors that we work for include:
Assessment of the wetland meeting the Ramsar nomination requirements
Kakadu National Park is renowned world-wide for its iconic landscape, composed of a diversity of wetland types ranging from intertidal mangrove forests and mudflats, to permanent billabongs and vast expanses of seasonal freshwater marshes.
BMT was commissioned by the Abu Dhabi Environment Agency to undertake advanced numerical modelling at a site within the Arabian Gulf. This was to assess the viability of developing aquaculture operations at the site.
BMT has been engaged by Water Corporation since 2011 to oversee this multidimensional marine quality monitoring program.
BMT is presently working with the Environment Agency – Abu Dhabi to establish a finfish aquaculture zone adjacent to Dalma Island in western Abu Dhabi
The Port of Brisbane Pty Ltd (PBPL) has developed an environmental monitoring program which aims to provide an understanding of the condition, values and stressors operating at and adjacent to the port area.
