Clients count on us to acquire the data needed for decisions on complex projects. Our services include defining data quality objectives, developing sampling and QA/QC plans, managing cruise logistics, and providing field services for oceanographic projects across the globe. Integral’s expertise includes large-scale data collection programs; deployment of state-of-the-art acoustic, optical, and water quality instrumentation; and analysis and modeling of coastal and open ocean systems.
Integral has worldwide experience in providing modeling solutions to our clients’ problems. Our numerical modeling of circulation, waves, and transport processes provides a cost-effective tool for site characterization. Experienced modeling staff use robust wave, current, sediment transport, and water quality modeling tools to provide high quality analysis and solutions for complex aquatic sites.
Sediment Transport Studies and Water Quality Analysis
We evaluate sediment and contaminant transport and water quality for projects involving dredging, monitoring, coastal protection, and contaminated sediment. Our tailored site-specific solutions may involve collecting wave, current, water quality, and tidal data, along with water and sediments samples for laboratory analysis. These capabilities ensure that in situ real-time measurements are informing any analysis required.
Hydrographic and Geophysical Surveys
Integral provides a full range of hydrographic and geophysical survey services, from planning and conducting surveys to analyzing data. Our primary areas of expertise include bathymetric and topographic surveying using tools such as multibeam sonar, side-scan sonar, magnetometers, and subbottom profilers. We also perform acoustic Doppler current profiler surveys, high frequency radar current measurements, and a full range of water quality monitoring.
Field and Laboratory Support
Integral’s field capabilities include instrumentation for measuring currents, waves, sediment properties, optical properties, and chemical constituents in the water column and at the sediment bed. We conduct shallow sediment coring and coordinate deep geophysical coring. Through our mobile and fixed laboratories, we perform unique erosion testing to accurately characterize sediment transport.
Coastal and Metocean Studies
Integral provides technical and environmental studies, engineering evaluation, and permitting to support coastal zone and metocean projects. Integral’s ocean monitoring systems obtain meteorological and oceanographic data for routine monitoring and scientific studies related to offshore oil and gas development and other projects. Our multidisciplinary expertise includes assessment of biological and ecological impacts on wetlands/sensitive habitats, marine species, and wildlife.
Marine Renewable Energy Studies
Renewable energy technologies require assessment of a site’s physical environment and characterization of potential environmental impacts. Our services span resource assessments, environmental impacts, and permitting and compliance for renewable energy projects. Integral scientists are also supporting the development of new technology, and have patented low-cost wave measurement devices for the characterization of wave resources and operation of wave energy converters.
Integral scientists characterize the effects of sound on the marine environment, including marine mammals and fish. Using state-of-the-art tools, we provide services to assess underwater noise generated by offshore activities, track marine mammals, and evaluate the movement of unexploded munitions. Technology development efforts include a low-cost real-time acoustic measurement platform, capable of 3-dimensional source localization to characterize sounds specific to offshore structures, ships, or construction activity.
Data Management and Visualization
From database design and management, to development of real-time, 3-dimensional visualizations of complicated data sets, we help clients and law firms analyze and understand their data.
Risk Assessment for Inland, Coastal, and Ocean Environments
A key component of our practice is the assessment of ecological and human health risks in complex and highly dynamic marine systems in the open ocean, estuaries and ports, and inland waters. We bring extensive experience to the assessment of risks and potential impacts associated with offshore projects, inclusive of physical processes as well as contaminants of potential concern, such as PAHs, PCBs, heavy metals, and emerging chemicals.
Natural Resource Damage Assessment
We assist clients and their counsel in managing natural resource damage (NRD) liabilities in offshore and coastal environments. On behalf of the State of Alaska, Integral led a technical synthesis of research collected over nearly two decades by Trustee, academic, and industry scientists on long-term injury by lingering oil resulting from the 1989 Exxon Valdez oil spill. Today, Integral supports major NRD activities related to the Deepwater Horizon accident in the Gulf of Mexico.
Ecosystem Assessment and Management
Integral is on the forefront of ecosystem assessment and management. We develop and apply models to quantify ecological production functions and impacts to biodiversity, and combine this information with economic principles to assess ecosystem services. For example, we have evaluated ecosystem level risks from mercury present in sediment and food webs near offshore installations, with particular focus on potential impacts on ecosystem services provided by regional fisheries.
Permitting, Design, and Studies for Ports and Harbors
We provide specialized evaluation, design, and permitting services for port and terminal operators and engineering firms involved in feasibility and design studies of new terminals or expansion of existing port facilities.
Dredging and Sediment Investigation
Integral has a full array of field evaluation and modeling tools to effectively and efficiently investigate dredge spoil disposal sites, channel infilling rates, dredge plumes, and coastal impacts associated with harbor structures or dredging activities.
