KEI has performed numerous multidisciplinary marine investigations that have included baseline studies as well as impact assessments for both industrial clients and regulatory agencies. Some of these studies were very large-scale, multiyear programs led by large firms where KEI played a key role in the success of the project. Investigations have included physical and chemical oceanography; marine biology; sediment dynamics; water and sediment characterization; toxicity evaluations; and bioaccumulation testing. Many of these investigations have focused on assessment of potential impacts from marine development including oil and gas operations, wastewater discharges and outfall construction, marine terminals, and ports and harbors.
